As the US Navy begins to pivot away from dependent tactical group paradigms and towards more independent striking units under distributed lethality, it will become increasingly necessary to revise our operational dynamics. The rapid increase in communications and tracking has led to an era in which a remote admiral can guide the hand of all units under his or her purview. We must resist such temptations. The remote warfighter knows significantly less than the commanding officer (CO) on the scene. Moreover, the administrative and procedural burden placed upon these commanding officers has sapped much of their tactical creativity and tenacity, as Ian Akisoglu has argued. Equipping ships with upgraded combat systems is all well and good, but the warfighters who utilize them and their operational paradigms must also be upgraded. We must decentralize tactical authority back down to the unit level and significantly enhance tactical knowledge and creativity.

The Naval Surface and Mine Warfighting Development Center (NSMWDC)’s Warfare Tactics Instructors (WTI) program is a huge step towards a low centralization, high unit proficiency operational model. As these WTIs spread throughout the Fleet disseminating ideas and rising to command, we will see a manifest change in unit-level tactical understanding and ability. However, the WTIs alone cannot overhaul our tired Preplanned Responses (PPRs) and outdated doctrines. They need to be empowered with the flexibility and out-of-the-box thinking that are the hallmarks of successful, evolutionary organizations. Our overly rigid combat procedures cannot handle the complexities of gray wars and supersonic conflict. Hence we must accomplish this shift through both the WTI program and a cocktail of long-term reforms: create accelerated CO pipelines with longer CO billets, enhance and widely distribute warfighting simulators, expand Personnel Exchange Program (PEP) billets, and form an across-the-board “task force” to resolve the over-management of unit commanders.

The Surface Warfare Officer (SWO) community has long suffered from having truly great officers mired in bureaucratic office jobs while their surface skills atrophy. Yes, it is crucial that our rising stars learn from staff and Pentagon billets, but their command leadership must be prioritized if they are to be retained. As VADM Rowden explained during the previous distributed lethality topic week, “Distributed Lethality is MUCH more than just putting more missiles on ships—it is about investing in warfighting expertise.” In this spirit we must push our rising stars to the tip of the spear as fast as possible. We must provide an accelerated command pipeline for our most able officers if we are going to get the elite commanding officers that are the bedrock of distributed lethality’s effective implementation. By giving these high potential candidates more early command opportunities and accelerated pipelines to CO/XO billets, we will keep our best and brightest plugged into the Fleet with the latest tactics.

Far too many officers have wasted years waiting for command only to then get short 12-15 month stints. This is a misunderstanding of what kind of commanding officers we want and how to utilize talent. A crew does not care about making sure every decent SWO gets the opportunity to command, they care about having the best CO possible. We push for quantity over quality for no real end as most post-command SWOs go on to do staff and other mostly dead-end oversight-based administrative jobs before retiring. Instead we must focus on providing our best prospective command officers with multiple years of command and sea time in order to make them the great, salty warfighters we need in future conflicts.
This adjustment will also renew Sailors’ faith in the position of CO as an elite surface warrior. One talented, highly-experienced CO with three years of DDG command is more valuable than three “good” quick-stint COs who are not able to come into their full leadership and warfighting potential in such a short time. If a CO is doing a great job, then there is no reason to rotate him or her out at 15 months just to let another officer wear the crown. Bureaucracy and entitlement should not get in the way of us accelerating, retaining, and utilizing the very best SWOs. No one should be destined for CO just because of good FITREPs. Only our very finest should assume command, and they should do so for multiple years to gain the critical, diverse experiences required of a true warfighting commanding officer. By allowing the best SWOs to skip obligatory shore duties and be screened early for command, and allowing more fleet elements to be commanded by early command LCDRs, we can offer an enticing value proposition to our most elite SWOs and keep them firing on all cylinders on their path to being the world’s finest naval captains. These COs are the glue that will make distributed lethality effective in practice.
Another crucial step is rolling out well-made, easy to use, and highly accurate warfighting simulators. These can proliferate at all levels and will have demonstrable impacts on units’ tactical knowledge, understanding, and performance. As a child I played Jane’s Fleet Command (1997) ad nausem. In the process I became an 8 year-old who could speak intelligently about Exocet missiles and the dangers of submarine operations in the Taiwan straits. By allowing SWOs to continuously fight the enemy, wargame, revise tactics, and practically learn of the world’s military capabilities, we will have a more engaged and competent cohort of warfighters. We must find a way to leverage the enormous advances in computing technology and wargaming in order to best equip the minds of those who will be on the frontlines in future conflicts. Drills, PowerPoint, and brief-based schools are banal compared to the image of a cruiser being struck by an SS-N-22 while you scramble an F-18 squadron to counterattack against a flotilla of enemy DDGs hiding in the shadows of mountainous islands. Instinct and competence are forged in the fire of conflict, so – sans conflict – we must utilize highly-realistic simulators as the best alternative.

Moreover, our officer corps must not remain a closed system, an echo chamber of similar sounds. In order to best equip our frontline leaders with a diverse understanding of how to fight and know how other navies think and operate, we must go to these other navies. Seeing how a foreign navy functions can be incredibly illuminating and provide crucial perspective on what we do right and how we can improve. From the Dutch to the Japanese, we have a broad array of powerful naval allies who use alternative systems and doctrines to pursue their national maritime objectives. The Personnel Exchange Program (PEP) as it exists today is a woefully inadequate means of accomplishing such an exchange of ideas. Only a handful of SWOs are able to participate and gain critical foreign insight and experience. By ramping up PEP, we will open our officer corps to a diversity of ideas, procedures, and technologies that can only help our critical thinking and tactical skills in unpredictable and complex conflict scenarios. The core of distributed lethality’s effectiveness will lie in COs’ ability to harness their wardrooms’ creativity and diverse experiences to fight unexpectedly in spontaneous, unusual battlefields. This skillset can be enhanced by observing and understanding other navies and their methods.
Ultimately, the most critical and immediate reform that is necessary is a Task Force designed to peel back the red-tape and operational micromanagement of COs. This group would be composed of all levels of officers from ensigns to admirals. It would discuss and delineate exactly which procedures and processes are absolutely necessary for a flag officer to control and kick all other authorities back down to the unit CO. In combat there is no time to wait for the admiral’s move; the unit commander must be able to execute in an innovative and effective manner in order for distributed lethality to succeed. The CO needs to feel that they are the one fighting a battle, not their boss a thousand miles away.
All too often we are slaves to procedure and protocol even when they don’t make tactical or operational sense. This environmental context is the key to tactical victory and must be exploited, not glossed over by a PPR. In the end, distributed lethality can only succeed if it is executed by well-versed, innovative, and empowered commanding officers and their crews. If individual units cannot fight independently, then distributed lethality will become little more than beefed-up units operating in the same defensive strike group arrangements we currently utilize. Therefore the solution to our current tactical weakness is twofold: restrain over-management and bureaucratization while enhancing opportunities for our best talent in order to produce independent, highly capable warfighters with the operational latitude to sink fleets and win wars. We must do everything in our power to make this a reality now before the first missiles fly in a hot conflict.

The BISMARCK, a single ship whose threat was sufficient to muster an entire fleet for the hunt.
The essence of naval warfare has always been opportunism – from the vague area of gravity generated by an in-port “fleet in being,” to the fleet-rallying threat generated by even a BISMARK or RANGER alone. The opportunity is generated by forces more mobile and self-contained than any army, more persistent than an air force, and empowered to act with no connection to higher authority in a domain that leaves no trace. It is that ability for a small number of independent ships, or even a single vessel, to provide opportunity and create, “battlespace complexity,” that is distributed lethality’s core. Distributed lethality is not naval warfighting by new principles; it is a return to principles.

The best defense is not an overwhelming obsession with defense.
Unfortunately, the virtuous autonomy of the past was, in part, only protected by the limited technology of the day. As technology allowed, decentralized execution was replaced by the luxury and false confidence of constant connection to higher authority through an electronic umbilical. It is the kind of devolution that turned into Secretary Gates’ nightmare, “I was touring a [Joint Special Operations Command] in Kabul and discovered a direct line to somebody on the NSC, and I had them tear it out while I was standing there.” In parallel, America began the ahistorical project of investing all offensive opportunity not even in a single class of ship, but a single ship surrounded by a fleet obsessed with its defense. As early as 1993, President Clinton stated that when a crisis broke out, his first question would be, “where is the nearest carrier.” Sorry, other ships! For the Navy to sensibly rebalance, distributed lethality must succeed. For distributed lethality to succeed, we must decentralize and de-tether mission command, weapons release authority, and weapons support systems.
Decentralized and disconnected methods of command must be embraced, as centralization is only an imagined luxury. Modern centralization is based on the assumption we will have the connectivity appropriate for it. This is no longer tenable in a world of increasingly advanced peers and hyundaized lesser adversaries. Anti-Access, Area-Denial (A2/AD) depends on opponents making themselves visible, of which electronic emission is critical. A2/AD will also inevitably seek to disrupt our C2 connections.

We don’t need no stinkin’ permissions.” “The Battle for Fox Green Beach,” watercolor by Dwight Shepler, showing the Gleaves class destroyer USS Emmons(DD 457) foreground and her sister-ship, the USS Doyle, to the right, within a few hundred yards of the landing beach, mixing it up with German shore batteries on D-Day.
The current major-node CWC concept will need to be broken down to a more compact, internal model designed around the Hunter Killer Surface Action Group. Rules of Engagement must be flexible to the point that American commanders need not look over their shoulders to a higher OPCON. Consider, the destroyer CO’s at Normandy didn’t consider waiting for direction or requesting approval before shifting from small boat screening to shore bombardment from the shoals. They recognized the opportunity – the necessity – and executed of their own will.
In contrast, today it might be a regular occurrence to double-and-triple check our actions with American OPCON while operating with NATO in TACON off Somalia. American CO’s could use the freedom to make pragmatic, on-the-spot decisions not only for immediate concerns of mission effectiveness, but as representatives of their higher military command and, potentially, the state. Coalition commanders would have greater trust in the spot decisions of their American counterparts, rather than worry they sit precariously atop a changing several-step staffing process.
Though encouraging equivalent RoE flexibility for coalition partners may be challenging, our autonomy may encourage our partners to interpret their home nation guidance in a flexibility equivalent to their trust in the US commander they fight beside. That lack of hesitancy will be critical during a conflict, and in that sudden moment in the South China Sea or Mediterranean when a small SAG of coalition partners find themselves in the midst of a conflict that has just begun. Imposing the peacetime discipline necessary to trust the CO’s we have trained, prepared, and empowered to do their jobs is the only thing that will jump-start a shift in a mind-set now dominated by subordination.
In the execution of more flexible orders, ships must be re-invested with control of their own weapon systems. CO’s oversee non-nuclear weapon systems that they do not control – that are solely the purview of off-ship authorities. In particular, as weapon systems like Tomahawk become deployable for ASuW, off-ship authority’s iron grip on their control must break. This decentralization also matters outside the stand-up fight at sea. The organic ability to program and deploy Tomahawk missiles for land strike allows surface ships to execute attacks of opportunity on land infrastructure, or execute and support opportunistic maritime raids as groups of marines harass adversaries, or turn isolated islands into temporary logistics or aviation operations bases. For winning the sudden-and-deadly fight in the littoral environment but integrating with opportunistic amphibious operations, the surface fleet could find some inspiration from the USS BARB, the only submarine in WWII to “sink” a train with its crew-come-amateur-commandos. From Somalia to the South China Sea, naval commanders should be told what to do, not how – and be allowed to do it. The less reliant the force is on these ephemeral links and the less these links are unnecessarily exercised in peacetime, the greater a force’s instinct to operate independently and with confidence in an imposed or needed silence.
CAPT Ramius, relieved to discover he is not dealing with “some buckaroo.”
There may be a level of discomfort with decentralization and disconnection. If leaders fear the impact of a “strategic corporal,” surely a “buckaroo,” as CAPT Ramius would call him, that would be truly horrifying. That fear would be a reflection of a failure of the system to produce leaders, not the importance and operational effectiveness of independence. There is a reason the US once considered the Department of the Navy to be separate and peer to the Department of War – noting the institution and its individual commanders as unique peace and wartime tools for strategic security and diplomacy. Compare today’s autonomy and trust with that invested in Commodore Perry during his mission to Japan or Commodore Preble’s mission to seek partnership with Naples during the First Barbary Pirates War. Reliance on call-backs and outside authority will gut a naval force’s ability to operate in a distributed manner when those connections disappear. Encouraging it by default will ensure the muscle memory is there when needed.
Finally, Distributed Lethality requires the hardware to allow surface combatants to operate as effective offensive surface units in small groups. The kinetic end of the spectrum, upgraded legacy weapons and an introduction of new weapon systems has been extensively discussed since the 2015 Surface Navy Association National Symposiumwhen VADM Rowden and RADM Fanta rolled out Distributed Lethality in force. However, weapon systems are only as good as the available detection systems. Current naval operations rely heavily on shore-based assets, assets from the carrier, and joint assets for reconnaissance. In the previous Distributed Lethality topic week, LT Glynn argued for a suite of surveillance assets, some organic to individual ships, but most deploying from the shore or from carriers. Presuming a denied environment, and commanders empowered to seek and exploit opportunities within their space, the best argument would be for greater emphasis on ship-organic assets. They may not provide the best capabilities, but capabilities are worthless if assets cannot find, reach, or communicate with a Hunter-Killer SAG operating in silence imposed by self or the enemy. They also prevent an HKSAG from being completely at the mercy or limitations of a Navy or joint asset coordinator – while simultaneously relieving those theater assets for higher-level operations and opportunity exploitation.
Ultimately – distributed lethality is the historical default mode of independent naval operations given a new name due to the strength of the current carrier-based operational construct. Admiral Halsey ordered CAPT Arleigh Burke to intercept a Japanese convoy at Bougainville, “GET ATHWART THE BUKA-RABAUL EVACUATION LINE ABOUT 35 MILES WEST OF… IF ENEMY CONTACTED YOU KNOW WHAT TO DO.” The surface fleet must embrace a culture assuming our commanders “KNOW WHAT TO DO.” We must build an operational construct in which acting on that instinct is practiced and exercised in peacetime, for wartime. The operational and diplomatic autonomy, as well as the OLD IRONSIDES style firepower of single surface combatants, is necessary to rebalance a force gutted of its many natural operational advantages. Distributed lethality must return the surface force to its cultural and operational roots of distributed autonomy, returning to the ideas that will maximize opportunity to threaten, undermine, engage with, and destroy the adversary.

–Wayne P. Hughes, Captain, United States Navy (ret)[i]
Introduction
In January of 2015 the U.S. Navy’s surface leadership publicly described the concept of distributed lethality.[ii] In broad terms, distributed lethality proposes creating small offensive adaptive force packages comprised of surface action groups (SAG) with a variety of support elements that operate across a wide region and under an adversary’s anti-access sea denial umbrella. Its purpose is to confound adversary locating and targeting while introducing a threat to their sea control ambitions. It is an offensive concept for the U.S. surface forces. After decades of investment in defensive technology, systems, and training to counter cruise missiles, ballistic missiles, and submarines, distributed lethality represents a course change for surface warfare, or at least a return to accepting a major role in sea strike that had been ceded to the carrier air wings. With several world powers developing challenging sea denial capabilities, establishing sea control in contested areas is again a concern of naval planners. A return to the offensive capability of surface action groups (SAG) is necessary to add resilience to a naval force structure operating in these contested areas. It also leverages the tactical offense, which in naval warfare is advantageous to overemphasizing defensive capabilities.
This paper describes a tactical doctrine to mature the concept of distributed lethality. By tactical doctrine we mean fundamental principles by which surface forces operate in the function-specific case of naval surface-to-surface engagements in a challenging electronic emission condition where adversaries may have an advantage in long-range detection of contacts.[iii] Its purpose is to guide efforts in providing surface forces with capabilities to conduct independent offensive actions and to develop specific combat tactics to employ organic surveillance assets, ships, and weapon systems to find, fix, and finish enemy surface ships in wartime.
Distributed Lethality empowers the surface navy to reclaim a role in sea strike. The Arleigh Burke-class guided-missile destroyer USS Stethem (DDG 63) fires a Harpoon missile during a sinking exercise as part of Valiant Shield 2014. (U.S. Navy photo).
The tactical doctrine’s essence is that continuous emissions will be fatal and allow the enemy to strike first. It is not meant to preclude use of additional capabilities provided by cross-domain contributions, but it does focus first on the ship as the basic unit to build a distributed lethality system. This is a key philosophy for surface ship survival in a modern missile surface duel and somewhat of a sea change: we must use networked systems when they are available, but not rely on them. To do otherwise invites creating our own vulnerability for the enemy to exploit.
This tactical doctrine is based on three principal objectives:
Out think the enemy
Out scout the enemy
Out shoot the enemy
Out Think the Enemy: Delegated C2 and Independent SAG Tactical Operations
Ensuring a Captain’s technical ability to exercise his ship’s entire kill chain, as well as the authority to employ his weapons under the general guidance of commander’s intent, relieves an external command and control burden, provides the fleet a faster search-to-kill decision cycle, and increases fleet resiliency to operate in the most demanding electromagnetic environments.[iv]Many individual SAG operations, each within their own operating areas controlling their own search assets, tasked with obtaining sea control in a restricted emissions control status, strive to achieve an overall cumulative sea control effect.[v] When a central authority can provide broad area targeting information, a blind broadcast across the operating area may be made. This concept mimics submarine independent operations to establish undersea dominance with each submarine having its own water space. It is not efficient in a network-centric sense, but it does complicate the enemy’s surveillance, search, command and control efforts and therefore enhances our fleet wide survivability.
Delegated command authority is not a new concept to the U.S. Navy. It empowers American initiative at the lowest level of command. We, however, must be careful that our desire for efficiencies in technological investments does not inhibit an individual Captain from exercising all his weapon systems and thereby restrict command initiative. For example, a communal surveillance resource like a maritime Global Hawk controlled from ashore provides cost-efficient sensor coverage usable by all in an operating area. But, if we rely on it, and it is lost due to enemy fire or intrusion, we blind all our SAGs. Instead, we should leverage its coverage when available, but rely on a SAG’s organic sensors to provide over the horizon targeting within its own operating area. Empowering American initiative at the lowest level of command is the most effective counter to a tactical surprise by an enemy.[vi]
This distributed lethality tactical doctrine implies each ship’s crew is trained to find, target, and kill without off-ship support, under a full range of emission control conditions. As ships are added to a surface action group, and other platforms added to the adaptive force package, the group must also be capable of fighting as a team, in any emission control condition. Specific techniques will be addressed in the scouting section.
Out Scout the Enemy: Fighting in the “Electronic Night”
Just as the U.S. land forces’ motto is “we own the night,” U.S. surface forces must be capable and proficient in fighting in the electronic night, or without the benefit of our powerful sensors and communications networks. Each additional electronic emission we rely on to find an enemy’s surface group increases the risk of counter-detection, and therefore being detected, localized and targeted by the enemy. The surface force’s objective must be to achieve this search-to-kill cycle faster than any adversary.
Passive electro-optic communications will need to be developed again between ships operating under the most restrictive emissions control (US Navy photo).
In Fleet Tactics, Wayne Hughes addresses both scouting and anti-scouting as methods to achieve a faster targeting cycle than the enemy.[vii] The U.S. surface navy’s current Distributed Lethality Task Force recognizes this and is exploring a concept of “deceive-target-destroy” to use both anti-scouting and scouting methods to gain the advantage.[viii] This paper will refer to these two broad categories while making tactical suggestions influenced by emission control conditions (or loss level of the EM spectrum) and number of platforms in an adaptive force package.
Single Ship Operation: Alone and Unafraid
Although adaptive force packages are envisioned as teams of several ship types with other support elements, the ability for each ship to operate independently in the most challenging emission control environment is a desired quality for force flexibility and resilience. In a truly contested environment friendly attrition may demand it. Technologies such as Low Probability of Intercept (LPI) radar operations, burst communications and bi-statistic active-passive operations using remote active sensors may allow for active emissions while limiting counter-detection. Nevertheless, we first address single ship operations in a completely passive condition with no organic air support or external targeting support. This is the most demanding scouting environment and is an effective anti-scouting technique particularly when combined with active decoys.
Completely passive scouting techniques for a single ship include visual, electronic surveillance, and acoustic surveillance. These techniques rely on the older concept of firing solutions being a function of the target’s relative position to the shooter, instead of requiring global positioning. Visual targeting is, of course, the least desirable as it exposes both forces to simultaneous targeting, but with many historical examples of combating forces “stumbling” upon each other, and as both surface forces may be conducting passive search, U.S. surface forces need to train for “quick response” firing. Technologies such laser target designators, long range guided gun munitions, wire-guided heavyweight torpedoes for surface ships, and visually fired missile systems may need to be developed to enhance U.S. combatants in the race to shoot first.
Passive and active search tactics with organic assets will need to be developed for each ship and helicopter pair (US Navy Photo).
Beyond visual range, passive electronic and acoustic surveillance may be conducted with onboard electronic surveillance receivers and passive hull mounted and towed array hydrophones. Their information can be converted to a targeting technique through the use of Ekelund ranging and target motion analysis as used by the U.S. submarine force. [ix] Depending on atmospheric ducting and ocean convergent zone conditions, these passive techniques may allow detection as far as 50 nautical miles, with area of uncertainty for targeting dependent on line of bearing error and suspected target range. The decision to shoot passively either on a line of bearing or with a bearing-range solution rests on the factors of missile seeker capability, size of area of uncertainty, the risk of counter-detection, and the level of concern for clutter.[x]
Relaxing the tactical condition slightly by receiving information from off-board organic sensors, we add the use of organic tactical air reconnaissance from embarked helicopters or UAVs, and employment of sonobouys as trip-wires. These assets can either enable passive cross fixing for cooperative targets[xi], visual targeting, or in the case of an intelligent passive sonobouy trip wire design, range information. For air assets, use of off-axis, passive low flying and pop up techniques are anti-scouting tactics to mitigate the risk of enemy counter-detection.
As additional emission control relaxations are allowed like the use of LPI radar, dual use radar (military or civilian), or allowing organic air or unmanned surface assets to conduct active search while the host remains passive (bi-static active-passive operations), additional area may be added to the surface ship’s search space and its area of operations. Use of air asset active radar sensors will extend search areas, but expose manned helicopters to the risk of being engaged. Specific active-passive tactics combined with pop maneuvers should be a priority for each ship-helicopter pair to develop. Care to use off-axis operations and random active search with these remote assets to avoid counter detection must be a given. One advantage to remote active operations is the possibility of seducing an adversary operating in passive mode to risk active emissions for a better defense condition, thereby increasing the U.S. ship’s chance to combine active and passive targeting information. This is different than the anti-scouting use of active decoys to entice the enemy to misuse their own targeting and striking assets, which is another appropriate tactic in this contested environment. Both techniques enhance the “Deceive-Target-Destroy” operating philosophy.
In addition to tactical deception using decoys, other anti-scouting techniques for single surface ship operations include concealment and evasion. Concealment may involve operations close to land to mask radar returns or confound missile seekers and electro-optic sensors; the use of commercial shipping or fishers to mask movement; or a combination of both. High speed evasion is used to increase the enemy’s area of uncertainty if we believe we have been localized by opening what is their datum on us.
As information is received from non-organic methods (national intelligence, higher command, or orbiting maritime aircraft) it may be silently fused with these other information to provide or enhance strike operations. Since these sources approach today’s normal methods of targeting they need not be expanded upon here.
The most challenging command decision for a Captain in this environment is when to switch from a passive offensive mode to an active defense condition in the face of a potential threat. If this is done too early based on only a few indicators we become susceptible to the enemy’s decoy seduction for us to provide targeting information to him. If too late, we mitigate our advantage in defensive hard kill systems. The Captain must weigh the timing and compounding of evidence and consider employing defensive soft kill systems first since these have been historically more effective than hard kill, and reveal less to the enemy’s scouting efforts. Activation of short range hard kill systems should follow and long range radar and hard kill systems employed last, all to give as little information to enemy scouts as possible. Of course, an active missile homing signal with a rapid increasing frequency shift is a red flag for all active defense systems. After an actual attack and successful defense when any electronic emissions are employed, passive high speed evasion should immediately follow.
Multiple Ship Operations: Better as a Team
Most capabilities for tactical employment of scouting and anti-scouting in various levels of emission control for a single ship apply to a multiple ship surface action group or an adaptive force package. Additional ships require formation configuration to best capitalize on passive cross bearing fixes allowing for environmental and acoustic conditions. For example, a two ship SAG may steam in a staggered line of bearing perpendicular to a threat axis with a distance between ships that gives a good cross fix area of uncertainty[xii] while allowing for mutual defense and electro-optic communications. Another example is a three-ship SAG steaming in roughly a triangular formation when no threat axis is available to cover a 360 degree passive surveillance area. Frequent individual course changes should be made along base course to put passive towed array beams in the best position to acquire acoustic information.
Exchanging information across a surface hunter-killer group in a strict emission control environment requires local C4I networks relaying on electro-optic communications such as laser, visual, or IR transmitters and receivers. Use of atmospheric layers by bending and reflecting signals may be explored to extend beyond line of sight, but intra-SAG communication that has no or little electromagnetic emissions will enhance SAG anti-scouting efforts.[xiii]
As emission control conditions are relaxed to employ organic off board sensors, helicopters, UAVs, or USVs may be positioned to either “complete triangles” in a two ship SAG, or be positioned forward to offset the threat axis and provide right angle passive surveillance. UAVs may be used as communication relays with low power emission or electro optic transmitters and receivers.
Options for dispersed SAG operations exist where one or two ships are sent miles ahead along a known threat axis in completely silent emission control. The ships in the rear are active on radar and control forward unmanned sensors, transmitting their information to ships in the van to create an opportunity for covert and surprise attack. This increases the intermittent risk to the active ships, but use of anti-scouting techniques of remote active decoys, LPI radar, and random active operations may be used mitigate the danger.
Multiple levels of active defense become an option with multi-ship SAG operations. Depending on indications and warnings of an attack, a SAG commander may decide the most capable air defense ship go active with hard kill systems while others employ soft kill only, or all go active, or some passively evade while others go active with hard kill. Again, these decisions are weighed against inadvertently providing targeting information to an enemy SAG too early in a defense cycle. The advantage of combat tactical doctrine is to permit training and rapid advances in tactical readiness through practice.
Out Shoot the Enemy: Don’t Take a Knife to a Gun Fight
Hughes writes “..the battle will be decided by scouting effectiveness and weapon range” and “the choice of tactics will also be governed by scouting effectiveness and weapons range.”[xiv] The obvious statement must be made that a SAG may kill no further than its longest missile system. Ship to ship missile systems should be designed for as much range as possible limited only by weight and size considerations for ship employment and possibly the ability to reload at sea. It is dangerous, and a bit arrogant for weapons systems designers to limit a missile range based on assumed future tactical situations.
Payload constraints of organic air assets limit the aggregate firepower needed to attack a capable enemy effectively, although they may be used to augment a shipborne attack, or attack independently with the purpose of making an uncooperative enemy go into active defense to provide better targeting data.
Traditionally, the key to effective surface missile attack is to penetrate enemy defenses by having missiles arrive while they are in a passive search mode (surprise), or to overwhelm his defenses with sufficient missiles arriving simultaneously. Another method is to attack with enough missiles, UAVs, and/or decoys to exhaust enemy weapon magazines and then follow with another attack. U.S. surface forces are susceptible to this tactic by nations with UCAV swarm capabilities.

When U.S. missile systems have the same range, or greater range than an enemy, a simultaneous attack is best conducted when sufficient scouting information is available for a targeting solution. If U.S. systems are out ranged by an enemy, the dispersed SAG tactic of silent shooters along the threat axis with active ships in the rear may be employed to get ships silently within range of their quarry. [xv] In both cases it is preferred to conduct missile launches in an emission control constrained status to make the arrival of the missiles a short notice event for the enemy.
Conclusions
With the guidance that doctrine serves the glue of tactics, [xvi] this paper’s purpose is to provide direction for specific tactic development to employ ships and weapon systems under the distributed lethality concept. This includes specific passive target acquisition techniques informed by electronic and acoustic capabilities and environmental conditions, targeting methods informed by missile seeker capabilities, and passive defense measures informed by enemy missile seeker capabilities. By nature these tactics will be in the classified realm and modified as new technologies are introduced for the SAG or emerge as a threat from our adversaries. However, the general goals of out thinking the enemy by creating situations to allow a faster search to kill cycle and resilient operational employment; out scouting the enemy through the intelligent use of scouting and anti-scouting techniques; and out shooting the enemy through missile range and/or tactics provide a foundation for detailed tactic exploration, at sea experimentation, and refinement.

[x] “Clobber” is a term for a sea skimming missile flying without seeker turn on accidently hitting a ship that is not the target, but along the bearing of the flight path.
[xi] The term cooperative target here means one that is radiating either electronically or acoustically
[xii] “Good” here is defined as an area of uncertainty which a surface missile seeker can cover when it goes active or if passive, the area coverage of its sensor. Depending on environment conditions, missile seeker size and passive sensor error, a distance between ships of 10 – 15 nautical miles and provide adequate targeting for a cooperative target to 100 nautical miles
[xiii] A team of Naval Postgraduate researchers including Bordetsky, Brutzman, Benson and Hughes are exploring a concept of “Network optional warfare” and proposing technologies to create a “mess network” for the SAG
This week CIMSEC is hosting articles exploring the US Navy’s Distributed Lethality concept. The US Navy is investigating distributed lethality as a potentially game changing approach for the conduct of naval warfare. We at CIMSEC are grateful for the Distributed Lethality Task Force’s partnership in launching this topic week, for the thought-provoking insights of our contributors, and to the sustained interest of our audience. The Task Force’s call for articles may be read here. Below is a list of articles featuring during the topic week, which will be updated as the topic week rolls out and as prospective authors finalize additional publications.
