The term multidomain has reached beyond mainstream military parlance to dominate defense-related discussions, concept papers, and op-eds. While the idea of operating across warfighting domains is hardly original, the rapid growth of capabilities tied to the newly minted space and cyber domains is forcing a re-examination of all previous military concepts and doctrine. This article explores the debate around multidomain battle (MDB). Developing a new warfighting concept (as opposed to a slogan or bumper sticker) is difficult because new concepts need to demonstrate that they are sufficiently better than the status quo at addressing the challenges and opportunities in order to justify the disruptive effects of the change. This, as it should be, is a high bar.

The desks of the Pentagon are littered with “transformative” joint warfighting concepts that have appeared with great fanfare only to fall into obscurity. Despite serving as a vehicle to explore ideas, in the end, concepts like Rapid Decisive Operations and Air-Sea Battle failed to move beyond the nascent stage. Some of this can be attributed to a natural resistance to top-down joint concepts, the difficulty of exploring future concepts while maintaining readiness, the lack of coherent institutional processes for examining concepts across organizational boundaries, and, ultimately, the lack of patience for what can be an intellectual slog. As a result, many such efforts were never sufficiently examined so as to generate compelling evidence to drive more than cosmetic changes across the force.

This article advocates two approaches to exploring MDB. The first is to link the MDB concept to the existing body of available evidence. The second is to generate new evidence through experimentation. These approaches are offered not because Service concept developers have not already begun this process—as evidenced by the MDB draft concepts and plans for U.S. Army MDB experimentation in 2018 and 2019. Rather, this article argues that in addition to the bottom-up development of what could arguably be deemed a joint concept, there should also be a parallel effort to explore the top-down or explicit joint, theater-level implications of MDB.

The term multidomain itself is most often used as a modifier for a particular application of military force, such as (multidomain) battles, (multidomain) operations, or (cross or multidomain) fires; however, more substantially, MDB promises more fluid, adaptive, and effective operations simultaneously across five domains (land, sea, air, space, and cyber). Although operations are conducted in and occasionally across these five domains, the promise of a concept that makes domain integration the norm and not the exception is a tall order. Extraordinary claims require extraordinary evidence.

The logic of MDB’s underlying tenets is widely accepted, but that is not the same as demonstrating the concept’s viability. Will the application of a multidomain approach enable the Department of Defense (DOD) to overcome current warfighting challenges? Will it allow the Services to seize new opportunities? Or, instead, will MDB distract the Services from restoring atrophied conventional warfighting capabilities? Perhaps more importantly, can MDB serve as a unifying concept that DOD business processes can be organized around for the development of future concepts and capabilities?

MDB is a future concept (perhaps near-future, but future nonetheless). As such, it “must be stated explicitly in order to be understood, debated and tested to influence the development process.”1 The maturation of a concept is a critical first step in the birth of any capability. Concepts are narrative descriptions of suppositions formulated from historical and contemporary experiences; however, as debatable propositions, they must be validated before they transition from concept to capability. This requires settling the debatable elements. This article thus argues that concepts on the scale of MDB require a campaign of experimentation that provides compelling evidence for the concept by fleshing out its operational and institutional contexts.2

The State of the Debate

Proponents of the emerging MDB concept make the case that the joint force must adapt to the times, or, as one author put it, “multi-domain battle . . . doctrine is being developed to address the interconnected, Omni domain battlespace of the 21st Century.”3 One of MDB’s strongest proponents, Admiral Harry Harris, commander of U.S. Pacific Command, argues that “MDB conceptualizes bringing jointness further down to the tactical level [by] allowing smaller echelons to communicate and coordinate directly while fighting in a decentralized manner.”4 Regardless of the operating theater and specific mission, tactical-level MDB operations, noted U.S. Army Pacific Commander General Robert Brown, will drive the Services to “change their distinct Service cultures to a culture of inclusion and openness, focusing on a purple (or joint) first mentality.”5 Rhetorically, at least, the emerging MDB concept is progressing from the often stated but little realized goal of Service deconfliction to increasing interdependency and, in the optimistic version of MDB, seamlessly integrated operations across domains.6

MDB critics dismiss its significance by arguing that it is old wine in a new bottle.7 Even proponents agree that the “idea and desire for cross-domain effects is not new” but contend the traditional Service-domain alignments are inadequate for coping with the new security environment.8 A more fundamental challenge is made by those arguing that the categorization of future war by domain—especially but not limited to the cyber domain—is neither logical nor practical. As one observer notes, “the word [domain] contains some built-in assumptions regarding how we view warfare that can limit our thinking . . . [and] could actually pose an intractable conceptual threat to an integrated joint force.”9

Joining the critics are the cynics, some of whom see MDB’s real purpose as programmatic: a ploy to restore or preserve force structure by returning land power to the tip of the spear in joint operations.10 Others see the concept as requiring deep institutional reforms that are simply unattainable.11 As one pessimist argued, “without consistently organizing, training, and equipping as a joint team, the Services will be ill-prepared to provide multi-domain capable forces to combatant commanders, continuing history’s trend of falling short of the vision of jointness.”12 The institutional questions loom large here. At one end of the spectrum there are calls to form separate Services for the space and cyber domains.13 At the other end, one MDB proponent provides fodder for the cynics by arguing that the only way to implement MDB is to create a single force and eliminate the independent Services.14

Running parallel to the ongoing MDB debate are distinct theater versions of the concept. Because practice trumps theory in the application of military force, how the MDB concept evolves will be strongly influenced by how the operating theaters find a way to employ its promise.

In the Pacific, where much of the initial energy behind the cross-domain idea began, MDB has been described as:

ground-based batteries of anti-aircraft, anti-missile, and anti-ship weapons, supported by long-range sensors and jammers, that can strike targets well out to sea. Islands defended by such Army batteries (or Marine Corps outposts) could serve as unsinkable anvils, with the Navy and the Air Force as the highly mobile hammers.15

In support of developing MDB, the Army has recently established a Multi-Domain Task Force in U.S. Army Pacific to accelerate the process of overcoming the tactical and technical challenges associated with reincarnating the Army’s capability to “sink ships.”16 This bottom-up approach to building a joint capability, as one commentator noted, has the potential to simultaneously work toward joint interoperability, interdependence, and integration. But this may fall short of answering how the Services can organize, train, and equip themselves to sustain the readiness required to operate as an MDB capable force.17

Meanwhile in Europe, the Army is offering MDB as a conceptual solution to a different, but in many ways familiar, problem set. The Russian army is no longer the colossus of the Cold War era, but it still presents the challenge of mass. Whereas the Russia’s army does not boast a raw-troop-strength advantage over the North Atlantic Treaty Organization (NATO), it is threatening a multidomain equivalence in long-range missiles, rockets, drones, sophisticated cyber attacks, jamming, and an integrated information campaign.18 The solution, argues the commander of the U.S. Army’s Training and Doctrine Command, is to take the multidomain fight to the adversary:

AirLand Battle started developing the concept of “extended battlefield.” This concept noted that different commanders had different views of the battlefield in geographical terms. [MDB] continues the concept of extended battlefield but now with a focus on the extension across domains and time. . . . [MDB] endeavors to integrate capabilities in such a way that to counteract one, the enemy must become more vulnerable to another, creating and exploiting temporary windows of advantage.19

This NATO-centric version of the MDB development process explicitly argues that, just as the earlier Soviet threat drove large-scale change in the U.S. military’s warfighting doctrines, the new Russian threat will drive long-overdue updates to Army force structure and critical warfighting capabilities, especially in the areas of long-range fires and cyber/electronic warfare.20

It is clear, then, that there are multiple lenses through which one can view the emerging MDB concept. Each perspective brings a unique set of operational and institutional contexts to the process of concept development. Having a unique perspective can be a healthy part of a robust debate, but progress requires an agreed-upon set of facts, or, in the case of an emerging concept, a common basis of evidence. The concept development challenge is to generate credible evidence that is relevant to decisionmakers from across the tactical-operational and conceptual-institutional divides.

The Emerging MDB Concept

According to a new Army–Marine Corps white paper, the MDB concept “describes how U.S. and partner forces organize and employ capabilities to project and apply power across domains, environments, and function over time and physical space to contest adversaries in relative ‘peace’ and, when required, defeat them in ‘war.’”21 The white paper posits three key tenets or “interrelated components of the solution,” as they are so labeled in the document.

First, MDB requires appropriate force posture for the “calibration of forward presence, expeditionary forces, and integration of partner capabilities to deter the adversary and, when necessary, defeat the enemy’s fait accompli campaign.” The latter is defined as an enemy campaign that seeks to rapidly achieve military and political objectives before an allied response can be generated. Next, MDB will be executed by resilient forces that “can operate semi-independently in the expanded operational area while projecting power into or accessing all domains.” Headquarters elements will use a mission command philosophy to integrate operations with advanced capabilities. Finally, converging joint force capabilities will “detect and create physical, virtual, and cognitive windows of advantage” during the three phases of an MDB campaign: competition, defeat the enemy in armed conflict, and return to competition. The white paper concludes by offering that the MDB concept allows U.S. forces to outmaneuver adversaries physically, virtually, and cognitively, applying combined arms in and across all domains. It provides a flexible means to present multiple dilemmas to an enemy by converging capabilities from multiple domains to create windows of advantage enabling friendly forces to seize, retain, and exploit the initiative to defeat enemies and achieve campaign objectives. Employing the ideas in this concept, the Joint Force can credibly deter adversary aggression, defeat actions short of armed conflict, deny the enemy freedom of action, overcome enemy defenses, control terrain, compel outcomes, and consolidate gains for sustainable results.

While these three tenets establish a useful framework for institutional considerations of the concept, they do not capture some of the explicit and tacit implications of MDB’s potential utility in a theater or joint campaign. To that end, this article offers the following four attributes, derived from the current MDB concept, as potentially useful in developing a joint campaign of experimentation to better understand the concept and to develop evidence for or against its military utility in the joint force.

First, despite the battle suffix, MDB may have more to do with campaigns than tactical actions. The battle aspects required to create windows of advantage are a necessary precondition to creating decisive overmatch.22 However, various descriptions point to an operational-level concept designed to maneuver friendly forces—and direct their kinetic and nonkinetic fires or effects—simultaneously across five domains.

Second, overmatch in one domain may trigger cross-domain multiplier effects that theater commanders can leverage to bypass, unhinge, and defeat an enemy. This, of course, works in both directions, which is why failing to adequately defend the force across multiple domains may have an outsize impact on war termination.23

Third, cyber and space domains may become tomorrow’s most valued battlespace given U.S. force dependence on the electromagnetic spectrum and satellite-enabled intelligence and communications. The continued development of sophisticated cyber weapons and employment means—as well as the direct and indirect weaponization of space—could exacerbate this trend.

Fourth, MDB implies the need to reexamine our approach to joint command and control. The authorities needed by geographic combatant commanders charged with planning, coordinating, integrating, deploying, and employing forces (and their effects) simultaneously across five domains will increasingly challenge the very concept of boundaries and the traditional relationships used to conduct joint campaigns.

The MDB concept remains more aspirational than practical at this point. To overcome the cognitive challenges and bureaucratic inertia described earlier, the concept needs to demonstrate that it is both more than the sum of its parts and sufficiently better than the status quo.

Operational Antecedents: Two Case Studies

Historical case studies aid the concept development process by contextualizing the problem. As critics and proponents alike have noted, “cross-domain” or combined arms operations stretch back into antiquity. The following case studies offer two examples of multidomain operations. Like any case study, some imagination is required to place the perceptions of the past into a future context. These cases provide some insights for how cross-domain capabilities, applied primarily at the tactical level, can have outsize operational implications.

Guadalcanal. The conceptual assumption in MDB is that the joint force commander must leverage the interdependencies occurring between diverse operational activities simultaneously across multiple domains. It is not enough just to manage, coordinate, deconflict, and integrate. In his 1987 article “Thinking About Warfare,” Lieutenant General Phillip D. Shutler, USMC (Ret.), used the 1942 South Pacific campaign to highlight the three strategic pathways (primarily air, sea, and undersea) that U.S. forces had to successfully transit during World War II before they could project combat power overseas. Although he labeled the strategic pathways regimes instead of domains, the underlying concept remains the same.

Shutler observed that once enemy airfield construction on Guadalcanal was completed, Japanese land-based aircraft were capable of attacking U.S. planes stationed 500 miles to the southeast on Espiritu Santo—threatening the supply lines connecting the United States with Australia and New Zealand. Accordingly, the Marines were ordered to seize the airfield on Guadalcanal to deny its use to the Japanese. In other words, U.S. land forces, in effect, were directed to create an antiair warfare shield at Guadalcanal to protect Espiritu Santo. But as the operational campaign progressed, the Marines’ (and later the Army’s) mission shifted from antiair warfare to enabling U.S. land-based aircraft to support subsequent island-hopping battles to the north and the eventual reduction of the Japanese strongpoint on Rabaul.

Initial success, however, required the United States to prevent Japanese ground forces from reinforcing Guadalcanal. A successful landing would have turned the battle into yet another symmetrical and protracted, single-domain, attritional fight between opposing land forces—both of whom sought to control the airfield. As Shutler noted, accomplishing this required U.S. submarines, surface ships, and naval aviation to establish maritime and aviation “shields” (that is, anti-submarine, anti-surface, antiair defenses) that the Japanese had to penetrate before their ground reinforcements could reach Guadalcanal.24

During the critical phases of the campaign, Japanese forces were unable to effectively penetrate the “multidomain” defensive shields, and the Marines were able to preserve their tactical overmatch ashore on Guadalcanal (approximately 11,000 Marines against 2,000 entrenched Japanese, many of whom were civilian laborers). The tipping point occurred on November 14, 1942, when U.S. naval forces attacked and sank seven Japanese troop transports that were carrying approximately 7,000 embarked Japanese troops trying to reinforce Guadalcanal.25 Although the Japanese did partially penetrate the U.S. shields during the campaign, they were unable to do so with sufficient combat power to alter the battle’s outcome.

Once U.S. air operations began at Guadalcanal’s Henderson Field, a multiplier effect occurred because the Japanese fleet was largely restricted to conducting night operations. This was due in part to additive U.S. airpower projected from ashore and concomitant flexibility gained from an untethered U.S. fleet that could inflict serious losses on Japanese shipping during daylight hours. This reduced Japanese flexibility and freedom of maneuver with implications well beyond the tactical area of operations and marked the start of the U.S. island-hopping campaign.

Like many similar operations in the Pacific theater, Guadalcanal had only marginal tactical utility as an island except for its value to the air domain. The airfield was the operational lynchpin that was denied to the enemy by adroit integration of multidomain activities on the land, sea, and in the air. This further enabled U.S. land-based airpower to support the drive from the Solomon Islands northward into the Central Pacific and eventually to the Japanese homeland.26

Falkland Islands. Almost 40 years after Guadalcanal, we can observe the same multiplier effect in a more modern campaign—the 1982 Battle of the Falklands—that revolved around a centuries-old territorial dispute between the United Kingdom and Argentina over the Falkland (Malvinas) Islands.27 Like the U.S. fleet in the Solomon’s Campaign, the United Kingdom established maritime and antiair shields around the Falklands in order to isolate the objective area, protect Royal Navy/Marines amphibious operations, and deny Buenos Aires the ability to reinforce its forces.

Multidomain actions in the Falklands campaign were numerous, and the multiplier effects these actions had on the campaign’s outcome were significant. The sinking of the 13,500-ton Argentine cruiser General Belgrano (armed with 15 6-inch guns and 8 5-inch guns) by three conventional torpedoes fired from the British nuclear submarine Conqueror took the lives of 323 Argentine sailors (slightly more than half of their total casualties suffered during the war). But more importantly, this action had a cross-domain effect that forced the Argentine surface navy to remain inside its territorial waters for the duration of the campaign.28 Additionally, the sinking of the Belgrano dramatically relieved naval surface pressure on Great Britain’s fleet operating in the Falkland littorals, which in turn allowed Royal Navy vessels on picket duty more time to visually detect Argentine aircraft being launched from the mainland and alert the British Task Force.29

The multiplier effect continued when British special operations forces, supported by naval gunfire, conducted an amphibious raid on Pebble Island to further reduce the Argentine air threat. The raid destroyed 11 forward-based Argentine aircraft. While Argentine helicopters and light aircraft were subsequently dispersed around the islands, the raid forced Argentina to withdraw most of its high-performance aircraft 400 miles back to the mainland.30 Thus, Argentine aircraft were required to fight at their maximum operating radius, which greatly reduced their time on station (Argentina had only limited aerial refueling capability). This was a major advantage for Great Britain’s amphibious fleet and embarked ground forces, who were worried they would not have air superiority during the amphibious landing.

Dismissing the Falklands as nothing more than a creative use of limited assets under extreme conditions risks overlooking key multidomain insights that contributed to operational success. If the notion of achieving dominance in one or more warfighting domains is a thing of the past, then learning to leverage a broader but perhaps relatively less robust toolkit is necessary. To modify a quotation often attributed to Winston Churchill, “Gentlemen we are out of overwhelming resources; Now we must think.”31

It might be easy to dismiss military case studies of the previous century as irrelevant to the challenges faced when looking forward into the current one. But it is worth considering how these multiple domains were integrated in the first place. The process (including technical, conceptual, and instructional efforts) of integrating new-fangled flying machines into the traditional warfighting domains of the land and sea began decades before a mature concept. It was not a straight line or a preordained outcome. The associated technologies and tactical concepts were leavened by decades of peacetime “experimentation” and wartime adaptation. The resulting capabilities for presenting an adversary with multiple, simultaneous dilemmas across domains changed the way the United States fights at both the tactical and operational levels of war.

Developing Evidence

The second source of evidence with which to examine the viability of the MDB concept is to look at it from operational perspectives and across a range of contexts. To do this, DOD should subject the MDB concept and its supporting tenets to a rigorous campaign of joint experimentation—even as the specific capabilities are still being developed. Joint experimentation in this context is an inclusive phrase meant to indicate the exploration of ideas, assumptions, and crucial elements of nascent MDB capabilities. To be clear, joint experimentation covers a wide range of activities (from structured seminars, virtual and constructive environments, to field events) and should be seen as complementary or undertaken in parallel with the development of specific capabilities or tactical employment concepts.

We employ the term campaign in association with joint experimentation to indicate that no single event can generate the quality or variety of necessary data. Moreover, only an experimentation campaign utilizing iterative activities with learning feedback loops (including workshops, wargames, constructive and virtual simulation, and live field events) can generate sufficient evidence to genuinely assess what it will take to realize, adapt, or abandon the MDB idea.

In terms of military experimentation, no single method has ever worked. The complex nature of military problems, and especially ones with interactions across five domains, argues for diverse forms of “discovery experimentation” to introduce novel systems, concepts, organizational structures, and technologies into settings where their use can be observed and Red Teamed.32 The results of such a comprehensive assessment will help identify MDB similarities and differences between the theaters, and will inform future doctrine, organization, training, materiel, leadership and education, personnel, facilities, and policy initiatives that must be addressed before MDB can become a deployable set of capabilities.

One of the most complex challenges in debates about future joint concepts is not the concept per se; it is the nature of jointness as practiced in a post–U.S. Joint Forces Command (USJFCOM) environment. Without digressing too far into the history of USJFCOM’s role in joint concept development and experimentation, it is worth contrasting the contexts. Formed in 1999, USJFCOM developed a generally top-down approach to joint concept development and experimentation. While this approach had some advantages, it often resulted in excessively large experiments, with the Services playing a limited or marginally productive role. When USJFCOM was disestablished in 2011, joint concept development reverted to the Joint Staff J7, whose time and resources for experimentation was more limited.33 More recently, Service or multi-Service–led efforts to develop and experiment with new joint concepts are increasing. This can be seen as a bottom-up, collaborative effort. While this approach has many practical advantages over the top-down approach, it is not without challenges—a key one being that the longer joint stakeholders (that is, combatant commands and prospective joint force commanders) remain spectators to the Service-dominated joint experimentation process, the less likely MDB’s theater-wide and strategic-level implications will be subjected to a full examination by the customer.

Under Joint Staff policy for concept development, experimentation begins after concept development. This may be adequate for narrow concepts or mission/domain capabilities where one Service has the lead. But this approach seems ill-suited for complex and multifaceted warfighting concepts such as MDB. As the two case studies indicate, cross-domain overmatch and multiplier effects are often discovered and subsequently leveraged in the course of operations. Early discovery experimentation with some level of joint analysis and sponsorship is essential. Not only will such early experiments increase the capacity to do joint experimentation, but they can also help co-develop Service concepts within a joint context.

As noted at the outset of this article, the MDB debate at this stage is a useful set of thought experiments, but it is not producing tangible evidence. Such evidence would shift the debate from a primarily subjective one to a more balanced and objective conversation. However, the recent history of joint concept development and the very nature of institutional jointness as practiced in DOD are not encouraging. According to the Joint Staff, joint concepts are assessed “using various analytical methods; the joint concept community evaluates both developing and approved concepts to determine whether they are feasible and promote informed decisions on developing new joint capabilities.”34

One potentially more lucrative approach would be to embark on a series of parallel joint discovery experiments designed to identify the specific characteristics, demands, and challenges associated with assessing the feasibility of MDB transcending theater-specific applications to serve as a more universal warfighting concept. Such a joint discovery experiment has historically been at the heart of military experimentation.35

The objective of discovery experiments is to learn, so it is useful to begin with a set of well-defined conceptual and operational conditions. One does not seek a well-defined “concept,” rather a statement of the military problem and a clear understanding of the initial military context. The discovery experimentation approach, supported by an initial data collection plan, is designed to tinker with the variables, modify the conditions, and challenge the assumptions and constraints in a way that dynamically helps refine a nascent concept and identify the kinds of capabilities worth considering. This notion of progressive learning through experimentation generates feedback that enables concept framing, definition, and refinement to occur dynamically.

The ability to use experimentation to explore the utility of emerging technologies and concepts is a force multiplier. Technology cannot be optimized until its impact on warfighting concepts and doctrine is fully appreciated. According to the National Academy of Sciences in a study done for the Navy:

By simulating future systems, [military commanders] can also learn how those systems will work in simulated combat environments and how to use forces equipped with such proposed systems. By such means they can explore new ideas and concepts for the use of variously composed and equipped forces against diverse anticipated threats, and they can learn how to integrate such forces on a large scale in the joint and combined force environment.36

One major challenge in calling for more joint experimentation is the large gap between the operating environment envisioned in the MDB concept and the availability of validated models and simulations. Earlier efforts to support joint analyses (both constructive and human-in-the-loop) with custom designed joint models “amounted to a costly failure with little or no resulting joint analysis capability gain for the Department.”37 Nevertheless, progress in MDB will require some capability to integrate space, cyber, and electromagnetic effects into models designed to explore the interaction of new capabilities and human decisionmaking. Any effort to explore MDB in a joint context must include an effort to integrate existing Service modeling and simulation tools (in the same bottom-up approach discussed here). This will help the Services to operate across new domains in support of specific joint priorities instead of attempting to create a standalone, top-down modeling and simulation solution.

Discovery experimentation is not a free-for-all, but a deliberately crafted and planned approach for addressing an issue long before it becomes a pressing problem. It allows operators to interact with new or potential concepts and capabilities to explore their military utility—something that is not often supported through traditional studies or hypothesis-based experiments. It requires careful attention to the specification and collection of data that will provide solid evidence for the conclusions reached by conducting experiments. If all these constraints are observed, discovery experimentation could be a valuable tool and a useful “way of weeding out ideas that simply do not work, forcing the community to ask rigorous questions about the benefits being sought and the dynamics involved in implementing the idea, or specifying the limiting conditions.”38

It is time to subject the MDB concept to discovery experimentation. To modify slightly Sir Michael Howard’s admonition about future doctrine, it is the “task of military science in the age of peace to prevent new capabilities from being too badly wrong” when the next war starts.39

The Air Force is developing a related Multi-Domain Operations concept that combines Air Force theater contributions into a unified air-space-cyberspace capability set in support of the joint force.

Saltzman makes the distinction with traditional combined arms by arguing, “[combined arms] is using the assets you have, in some cases from different functions or different domains. Whether it’s artillery, armor, infantry, aviation, those are the traditional arms we’re talking because a lot of times we talk about combined arms in terms of the Army sense of things.”

Although none of these aircraft threatened the overall outcome of the campaign, they remained a major concern throughout it.

Warfare Tactics Instructor: A Unique Opportunity for Junior Officers

By Rear Adm. John Wade and Cmdr. Jeff Heames

Rapid technological advancements and the re-emergence of near peer competition require that we continue to invest in high end tools – platforms, weaponry, and sensors. Equally important are the tactics to employ them and the associated training investment we must make in today’s warfighters and future leaders in the Surface Warfare Officer (SWO) cadre. The centerpiece of an amped-up warfighting culture in surface warfare is the Warfare Tactics Instructor (WTI) program, available to all division officers, department heads eligible for shore duty, and a small number of limited duty and chief warrant officers.

The ideal onramp into the WTI community is during the first shore tour following completion of at-sea division officer assignments. This timing allows the WTI program to fit neatly in a career pipeline. Three attributes set the WTI program apart: the opportunity to develop expertise in areas the Navy needs, exposure to exclusive professional development opportunities during the readiness production tour and throughout a career, and the empowerment to make significant contributions at a very junior level.

Expertise

The ability to develop confidence through professional expertise early in a career has a profound accelerating effect on an officer’s development, and directly contributes to a sense of purpose and fulfillment. WTIs are afforded the time, resources, and experience-building opportunities they need to learn while making substantive contributions to tactics and warfighting proficiency.

The WTI program offers a gateway for young officers to develop deep tactical expertise in the fields of Integrated Air and Missile Defense (IAMD), Anti-Submarine/Surface Warfare (ASW/SUW), and Amphibious Warfare (AMW). Each field begins with a two week Instructor and Tactics Course (ITC) followed by a tailored, 14-16 week course of instruction. During this instruction period, prospective WTIs are mentored and coached to develop their skills at leveraging the Plan, Brief, Execute, and Debrief (PBED) methodology for rapid learning. Following this training, WTIs complete a 24-month “readiness production tour” at SMWDC headquarters or one of four SMWDC Divisions – focused on Sea Combat, IAMD, AMW, or Mine Warfare – or selected training commands (CSG-4/15, TTGP/L, ATG, CSCS, or SWOS, to name a few). During this tour, WTI skills are matured both in the classroom – and at sea – during Surface Warfare Advanced Tactical Training (SWATT) and other fleet training events.

Learning by Teaching

The emphasis on teaching as a basis for learning is based on an idea espoused by the Roman philosopher Seneca, who declared, “docendo discimus” or, “by teaching, we learn.” This model of learning is also used to develop WTI candidates, which is why instructor skills are a main focus of ITC. Quality of lesson delivery is established through a rigorous standardization process that must be completed for each lecture delivered by a WTI. It’s not uncommon for a WTI to invest weeks or months of research, as well as conduct numerous “murder boards” with fellow WTIs, technical experts, and senior officers, before presenting at the podium. The process is meant to maintain a high standard of instruction where WTIs have established mastery of content and exhibit confidence in delivery.

Focused Specialty Areas

During initial WTI training, students are assigned relevant tactical projects that match critical fleet needs and account for student interests. Projects often involve new technology or capability that must be thoughtfully and effectively integrated into maritime warfare doctrine. Other projects center on updating existing doctrine or repurposing existing systems in new and innovative ways. Specialty areas and projects are assigned based on WTI preference and crosscut broadly, from high-end tactics to training systems and learning science.

Focus area research often extends past initial WTI training, into subsequent readiness production tours, and beyond. SMWDC provides mentorship, applies resources, and opens doors to connect WTIs to thought leaders, technical community experts, industry partners, and community leaders to develop their specialty area work.

Coaching and Training Skills

WTIs are the core workforce of SMWDC’s advanced tactical training at sea. They rely on replay tools that include systems data, voice, and other information to rapidly build ground truth and facilitate debrief sessions. Equipped with irrefutable data on what really happened, the “I thought” and “I felt” ambiguities are driven out of the debrief process, enabling shipboard watch teams to learn and grow together more rapidly.

The combination of WTI knowledge, replay-assisted PBED, and specialized training focused on team dynamics and coaching skills offers a powerful method for improving learning across the fleet. The aim is to create an environment of transparency and mutual trust among watch team members, where Sailors enter debrief sessions eager to identify their own shortfalls in order to improve team and unit performance.

At-sea training allows WTIs to observe multiple ships and teams across a variety of training and operational circumstances. The WTIs gain practical insight into how doctrine plays out on the deckplates, as well as hone their ability to identify team performance issues during at-sea training. While the immediate objective is to improve tactical proficiency and unit performance, the skills WTIs gain are extraordinarily useful in future roles as department heads.

Performance Analysis

The final link in WTI expertise development leverages the strong partnership between SMWDC and the technical community. Our ability to measure and analyze performance among units is a challenge due to complex weapons systems, ship configuration variance, and the number of watchstanders distributed in different controlling stations. To build a clear picture of how tactics, training, and systems converge into warfighting capability, a detailed event reconstruction must take place that considers system actions, operator actions, and tactics.

Naval Surface Warfare Center (NSWC) Corona, Naval Undersea Warfare Center (NUWC) Keyport, and SMWDC have developed a Data Analysis Working Group (DAWG) to conduct performance analysis of SMWDC training events. The intent is to extract empirical, data-driven insights from the careful analysis of systems, operators, and tactical performance.

The process is laborious, but straightforward. Following at-sea training, event data is extracted from unit combat systems and sensors and then brought to NSWC for detailed analysis. Following initial analysis from the technical community, WTIs and SMWDC leaders stand up a 1-2 week DAWG event.

By examining system performance, operator performance, and tactics as a consolidated effort, the process can lead to discoveries not captured by direct observation – system anomalies, operator actions, and flaws in tactics. Findings and lessons learned can be very useful because they are underpinned by empirical data and technical analysis. To date, more than 40 weapons system performance anomaly reports have been generated from DAWG events. Systems issues have been identified and funneled to the appropriate technical community to resolve, tactics have been updated, and numerous operator performance issues have been provided to the training community as opportunities to grow or strengthen curriculum. This allows SMWDC to advocate for tactical updates among partner warfighting development centers and provide feedback to the TYCOM and Surface Warfare training enterprise.

For the WTI, immersion in performance analysis activity with civilian technical experts offers a unique lens into how weapons systems, operator performance, and tactics are all linked to create combat potential.

Professional Development

Because the program is highly sought after by driven, focused professionals, the majority of WTIs are on track to return to sea as department heads. Notably, WTI cadre retention is double historical averages in the Surface Warfare community at roughly 70 percent. WTIs heading back to sea have a notable advantage given the training they receive and the experiences they gain at a formative stage of their career that others simply do not.

Assignment Consideration

Similar to officers with other subspecialty skills – Nuclear Program, Financial Management, Operations Analysis, and Space Systems – WTIs have unique skillsets based on their focus areas. For example, IAMD WTIs in readiness production tour billets at the Naval Air Warfare Development Center in Fallon, Nev., have completed the Carrier Airborne Early Warning Weapons School, becoming dual-patched WTIs. These officers are among very few in the Navy with expertise in Integrated Fire Control (IFC) from both the Aviation and Surface perspectives.

To maximize the return on investment for these unique WTI skills, SMWDC is closely aligned with PERS-41 in the distribution process, ensuring future assignments leverage these strengths (e.g., assigning a WTI with IFC expertise to IFC-capable units). While assignments will always consider many variables, this close relationship ensures WTI experience and skills are considered during the assignments process. 

Continuing Education

WTI training and readiness production tours leave less time to complete graduate education between division officer and department head assignments. To mitigate this challenge, WTIs are awarded priority for graduate degree programs at service colleges as well as the Naval Postgraduate School distance learning programs.

Additionally, WTIs are afforded unique and exclusive professional development opportunities that extend throughout their careers. Annual “Re-Blue” events held at SMWDC Divisions are a venue for WTIs, both in-and-out of readiness production tours to attend week-long immersive workshops where information is exchanged and re-distributed into the fleet. Funded travel to Re-Blue events keeps WTIs connected to the sharp edge of the operational Fleet during their readiness production tours and beyond. Re-Blue events are an example of SMWDC’s commitment to maintaining excellence within the WTI cadre.

Empowerment

SMWDC is unlocking the potential of our junior officers and post-department heads, empowering them to swarm and solve difficult problems. While experience will always have a place at the table, this new generation of naval officers holds several key advantages. Unencumbered by “the way things have always been,” these officers are better suited to envision a future that leverages trends in technology, communication, and learning. This is an area where fresh perspective is an asymmetric advantage. WTIs bring their creativity, ingenuity, and initiative to developing the next generation of cutting-edge tactics, techniques, and procedures.

WTI’s are creating a positive impact in the Fleet. From immersion in their focused specialty areas to tactical projects, and deckplate innovations, WTIs have built an impressive list of contributions since SMWDC’s formal establishment in June 2015. Consider the below examples of projects inspired, developed, and built by WTIs, while being supported by SMWDC leadership.

  • Lt. Cmdr. Katie Whitman was the lead action officer developing the SWATT in port and underway curriculum from the ground-up, using best-of-breed practices culled from aviation and other communities. She developed replay-assisted PBED for rapid learning and crafted the SWATT performance analysis strategy, which are now distinctive features of the exercise.
  • Lt. Ben Graybosch partnered with NUWC Keyport to revise the VISTA replay tool to include A/V-15 sonar system data, enabling the detailed “ground truth” ASW replay for unit sonar teams within 4 hours of completing ASW events. Graybosch’s effort moved the needle on ASW ground truth replay availability from days or weeks down to hours after an event. With replay tools that offer ground truth much earlier, we can increase the velocity of learning within surface ASW teams dramatically. VISTA is now employed in every ASW event supported by SMWDC and other fleet training events.
  • Lt. Brandon Naddel was the lead author for the Naval Surface Gunnery Publication released in 2017. Naddel and his team revised a 15-year-old document laden with technical jargon and dated systems into an information-packed and easily understood tactical publication relevant to all surface ships.
  • Lt. Tyson Eberhardt authored tactical guidance for the emerging Continuous Active Sonar (CAS) capability. Eberhardt leveraged at-sea training and experimentation events to rapidly refine tactical guidance in 2017. Based on his work, the CAS capability was used to great success in the operational fleet later that year.
  • Lt. Matt Clark designed and built a Target Motion Analysis (TMA) training tool accessible on any classified terminal with built-in performance analytics. Clark’s tool has potential to provide insight on the rate of individual skills decay in TMA. This type of information could then be used to inform currency thresholds for future training requirements.
  • Lt. Aaron Jochimsen was the lead author for the SM-6 TACMEMO. He conducted extensive research on SM-6 that included production site visits, participation in wargaming and experimentation, as well as involvement in fleet missile firings.
  • Chief Warrant Officer Troy Woods completed a readiness production tour with the Center for Surface Combat Systems, where he was involved in training individuals and teams on IAMD skills. Woods was subsequently assigned to USS BUNKER HILL (CG 52), where his skills are being put to use as lead IAMD planner within the Theodore Roosevelt Carrier Strike Group. Woods attended the IAMD WTI Re-Blue event in Dahlgren, Va., to share the operational perspective with his fellow IAMD WTIs and receive the latest tactical information from SMWDC IAMD Division leadership.

The WTI Program is a career opportunity that values our officers and empowers them to solve complex and challenging problems. SMWDC WTIs naturally have an eye toward innovation, are re-building the surface warfare library of tactical guidance, are shepherding new capability from delivery to operational success, and challenging the status quo in surface warfare training. Lt. Jochimsen, the lead author of the SM-6 TACMEMO, said it best:

“The opportunity to develop deep knowledge – Subject Matter Expertise – is a game-changing confidence builder as a junior officer. I feel much more prepared for the challenges of an at-sea department head assignment after completing a WTI readiness production tour.”

Conclusion 

The WTI cadre of warriors, thinkers, and teachers are uniquely equipped with the experience and knowledge to make significant contributions during their readiness production tours and throughout their careers. It is no coincidence that the same skills involved in developing tactical mastery are extraordinarily useful in subsequent assignments at sea – department head, XO, CO, and major command.

While statistically significant trend data does not yet exist for WTI selection for career milestone billets, members of the WTI cadre performed very well during recent administrative boards.

For those looking to increase their confidence and competitiveness for future at-sea assignments, the WTI program offers a unique opportunity to strengthen their professional attributes and shape the Navy for years to come.

A2/AD and the Long Lance Torpedo

In this two-part series on contested access in the Solomon Islands campaign, Part One will explore one of the IJN’s most successful weapons of World War II, which made area denial a reality for the IJN, the Type 93 ‘Long Lance’ torpedo. Part Two will compare the similarities of the Long Lance development to that of the DF-21D and discuss how the U.S. ultimately dealt with the Long Lance. 

By Bob Poling

As I mentioned in my introductory post, the intent of this column is to explore the historical use of strategies, tactics, and technologies which fall under the broad definition of anti-access and area denial (A2/AD). One of the most common practices of a nation using A2/AD is the adoption of asymmetric tactics and associated weapons systems to mitigate an adversary’s advantages in numbers and technology.

However, it this column’s assertion that the U.S. Navy may lack an appreciation for these asymmetric threats.  This is not due to a wanton disregard for A2/AD strategies and tactics, nor an unhealthy reliance on its weapons systems and technology. Instead, this lack of appreciation can be attributed to two factors. First, the U.S. Navy has not been truly challenged at sea since the end of the World War II. As such the Navy has produced several generations of naval officers that have no high-end combat experience. The second factor is a byproduct of the first. Since there has been no combat at sea for over 70 years, the Navy lacks case studies for training its current batch of officers. Therefore, this column will tap into the Navy’s combat history and offer historical examples that are arguably useful for contemporary and future challenges. For instance, the Solomon Islands Campaign is littered with examples of what today can easily be categorized as A2/AD strategies and tactics.

Contesting Access in the Solomon Islands

During the Solomon Islands Campaign, the Imperial Japanese Navy (IJN) employed a strategy based on anti-access, in which they aimed to keep out the U.S. and allied powers from the inner reaches of the Japanese Empire. To that end, Japan developed several platforms, weapons systems, and tactics which would facilitate this strategy. Moreover, in the years leading up to the start of WWII, the IJN faced a predicament like the one that drove the Chinese to develop the DF-21D anti-ship ballistic missile, that is, the challenge of how to deny freedom of access and maneuver to and ultimately defeat the U.S. Navy.

Type 93

One of the most sophisticated and deadly weapons of WWII was the Type 93 torpedo. This torpedo was the ship killer of that era. The asymmetric tactics developed for its use in combat were revolutionary. Much like the DF-21D, the Long Lance was in development for 20 years. Experimental work began in 1916, and by 1935, IJN weapons designers had produced a working 24-inch torpedo. “Long Lance was the most powerful weapon of its kind in the world as it was 29ft, 6.3 in long, weighed 5982 lbs, carried a warhead of 1080 lbs, and had a range of 21,900 yards at 48-50 knots, 35,000 yards at 40-42 knots or 43,700 yards at 36-38 knots.”1 Granted, launches beyond 20 miles were unlikely, but the Type 93 gave the IJN a standoff weapon that could be launched outside of visual detection range, especially at night.  Additionally, the Long Lance out-ranged the guns of all USN ships except battleships, making this a particularly effective long range anti-access weapon. Finally, the U.S. Navy had no effective countermeasures or defenses against this torpedo.

To optimize the capability and destructive power of the Long Lance, the IJN incorporated it into their night-fighting tactics. “The origin of the Japanese Navy’s tactic of stressing the night engagement was old; in both the Sino-Japanese and Russo-Japanese wars this tactic was used.”2 It should have come as no surprise that the IJN continued to develop night-fighting tactics given their success in these two conflicts. However, the USN surface forces had an air of invincibility and arrogance about them and held the IJN in contempt. 

This contempt was based on beliefs that the USN was technologically superior and more experienced, especially when compared to the IJN, which was only 70 years old.3 While USN battle tactics were still dominated by the pursuit of daytime gunnery engagements, and some U.S. Navy ships had radar, the IJN developed tactics to counter this practice mainly by the use of torpedoes coupled with guns fired in nighttime engagements. “Standard Japanese night-fighting doctrine was to launch torpedoes first, use gunfire only when necessary and searchlights as little as possible.” As the Long Lance was wakeless, it was nearly impossible to detect at night. The IJN counted on the USN to be taken unawares by this tactic and thus to be unlikely to maneuver. To facilitate this tactic and remain undetected, the Japanese’ primary method of detecting surface ships was the use of superb night optics. In fact, the IJN was constantly refining night optics during the interwar period and was regularly producing world-class optics in the 1930s. “Particularly noteworthy were binoculars of powerful magnification and light-gathering capacity, featuring lenses as large as 21 centimeters.”To use these binoculars, the IJN selected men to be trained as Masters in Lookout, and these petty officers trained day and night to hone their skills.6 No other navy of the era had lookouts as highly trained as these. When combined with the night optics, these men were in fact a part of the Long Lance weapons system. 

The U.S. Navy’s first encounter with the Long Lance was in the early morning of August 8, 1942 in Savo Sound off Guadalcanal. On the previous morning, the U.S. Navy had landed Marines on Guadalcanal and Tulagi as part of Operation Watchtower. Upon hearing the news of the invasion, Vice Admiral Gunichi Mikawa, Commander 8th Fleet, pulled together a force of seven cruisers and one destroyer and sailed for Guadalcanal that afternoon.

Arrayed against Mikawa were six heavy cruisers, two light cruisers, and eight destroyers, which were divided into three groups. Of the eight U.S. destroyers, two were assigned radar picket duties patrolling both the western and eastern approaches to Savo Sound, but Mikawa’s striking force remained undetected. According to IJN accounts both radar pickets were detected visually at 10,000 meters by the IJN cruiser Chokai. However, neither Blue nor Ralph Talbot made radar contact even though Mikawa’s ships were only a little over five miles away.7 Once clear of the picket, Mikawa gave the order to attack.  The IJN achieved complete surprise, and its use of an A2 weapon coupled with asymmetric tactics had devastating results on the USN and RAN. As RADM Crutchley wrote,

“The result of the night actions fought during the night 8th-9th August proved costly. Four of our heavy cruisers – Vincennes, Quincy, Astoria and Canberra had been lost. Another heavy cruiser Chicago had been damaged and required dockyard repair. Two destroyers had been damaged, Ralph Talbot fairly heavily and Patterson not seriously.8

During the engagement, IJN cruisers Chokai, Aoba, Kako, Kinugasa and Furrutaka fired 45 Type 93 torpedoes.9 Of the four USN cruisers participating in the battle, Quincy and Vincennes were sunk due to damage caused by Long Lance torpedo hits and Chicago had her bow blown off by a Long Lance, which immediately took her out of the fight.10 The other two cruisers lost in the battle, Astoria and Canberra, both were sunk due to damage inflicted by naval gunfire from the IJN cruisers.11

Two things stand out here as noteworthy anti-access tactics. First, part of an area defense strategy will likely include forward-based forces that can rapidly respond to an incursion and immediately conduct active defensive operations. In this case, it was Mikawa’s eight ships which caught the U.S. Navy completely unawares even though this operation was being conducted inside the IJN’s defensive sphere. The second A2 tactic was the night attack using a long-range, undetectable weapon. Much of today’s angst regarding A2 systems assumes the very same thing. Once the defenders realized they were under attack, it was entirely too late to respond and because of the nature of the Long Lance, it remained undetectable. The element of surprise was made all the more decisive by the effective use of a powerful anti-access weapon. 

Conclusion

A2 tactics are nothing new, and today’s Navy is aware of what those tactics may entail and which potential adversaries embrace these tactics today. Back in the Solomons, the USN’s troubles with the Long Lance would continue well into 1943. Ultimately, the Navy learned to adapt its tactics, techniques, and procedures (TTPs) to mitigate the threat posed by the Long Lance. However, what is important in this example is that no active counter measure was developed. Instead there was a realization that the threat was not going away, and a significant amount of risk was going to be present while conducting operations in the waters of the Solomon Islands. Acceptance of significant risk is an important part of defeating an adversary that aligns its strategy and tactics with A2/AD. Part Two will explore this aspect as well and how the Navy ultimate dealt with the Long Lance threat.
