While Amazon continues to pilot its fully autonomous drone delivery system, Amazon PrimeAir, an autonomous delivery system millions of times larger is occurring at sea. And whether you are the passenger on-board a cruise ship or you hire a shipping company to transport your belongings overseas, in a few years, you will increasingly be at the mercy of a self-driving ship.
The prevalence of self-driving ships, or in more technical terms, autonomous surfaced vessels (ASV) or unmanned surfaced vessels (USV), which operate either remotely or completely independent of humans, is growing. And while for centuries mariners have sailed in awe of the ocean’s size and reverence of its might, the emergence of the self-driving ship ushers a new era of commercial economic opportunity as well as maritime security risks of miscalculation.
Similar to self-driving cars, most of the technology necessary for the development of a self-driving ship is mature and available at reasonably low cost. Using state-of-the-art computer algorithms within advanced radar, navigation, acoustic, and optical sensor payloads, self-driving ships are expected to operate more efficiently and safely than those operated by humans.
However due to the technical complexity, lack of legal precedent, and political hedging associated with self-driving ships, one can expect the wave that brings higher commercial profits to also lower the propensity for international consensus on their use. Self-driving ships present challenges like those faced by federal and state governments today in implementing safeguards when introducing self-driving cars to the public. Yet unlike self-driving cars, these policies will need to address centuries-old maritime legal constructs, sovereignty protections, and universally established rules for how vessels interact on the high seas. The necessity of these policies to accommodate the commercial interests of ships longer than the height of the Empire State Building and communal practices of family owned fishing trawlers will be a significant challenge to policy makers.
Unlike driving your car on a well-regulated interstate highway system, moving further away from a given nation’s coast corresponds with the transition of sovereign territorial waters to an international patch work of treaty obligations under the United Nations (UN) Convention on the Law of the Sea and regulatory organizations, notably led by the International Maritime Organization (IMO). With its UN mandate to promote safe, secure, efficient, and environmentally sustainable shipping, the IMO has an opportunity to advance maritime safety, security, environmental protections, and economic opportunity through its embrace of technological innovation.
Nations seeking to capture a maritime strategic advantage may see the application of self-driving ships as a force multiplier to maritime search and rescue, mine clearance, and offensive operations. Conversely some nations may view the application of self-driving ships as their relief valve to unusually high operational demands resulting in accelerated personnel fatigue and vessel deterioration. When coupled with future advances in sustainable energy sources (solar, nuclear, and lithium-ion battery), self-driving ships will become an attractive investment alternative for global powers in extending their ability to project power by sea. Undoubtedly this regional and global great power competition will heighten the risk of miscalculation and unintentional conflict escalation as evident in the December 2016 seizure of an American unmanned oceanographic survey ship by Chinese naval forces.
For international maritime bodies, such as the IMO, International Seabed Authority, and International Whaling Commission, self-driving ships offer a low-cost approach for monitoring and reporting nation-state and private violators of maritime conventions. Through member nation financial support, the UN application of self-driving ships could respond to sustained maritime humanitarian crises while depoliticizing involvement and the risk to entrapment by member nations. This may serve as a pretext for the establishment of a sustainable internationally recognized unmanned maritime peacekeeping mission with the capacity to actively investigate illegal fishing off Somalia’s coast, resource exploitation near Fiji, environmentally damaging practices to the Great Barrier Reef, or freedom of navigation within the disputed South China Sea.
However, before the rewards of self-driving ships can be realized, their challenges must be acknowledged, accepted, and addressed through a combination of active diplomacy, smart policy, and visionary thinking.

The following two-part series discusses the command and control of future autonomous systems. Part 1 describes how we have arrived at the current tendency towards detailed control. Part 2 proposes how to refocus on mission command.
Today’s commanders are accustomed to operating in permissive environments and have grown addicted to the connectivity that makes detailed control possible. This is emerging as a major vulnerability. For example, while the surface Navy’s concept of “distributed lethality” will increase the complexity of the detection and targeting problems presented to adversaries, it will also increase the complexity of its own command and control. Even in a relatively uncontested environment, tightly coordinating widely dispersed forces will not be a trivial undertaking. This will tend toward lengthening decision cycles, at a time when the emphasis is on shortening them.1 How will the Navy execute operations in a future Anti-Access/Area-Denial (A2/AD) scenario, where every domain is contested (including the EM spectrum and cyberspace) and every fraction of a second counts?
The Navy must “rediscover” and fully embrace mission command now, to both address current vulnerabilities as well as unleash the future potential of autonomous systems. These systems offer increased precision, faster reaction times, longer endurance, and greater range, but these advantages may not be realized if the approach to command and control remains unchanged. For starters, to prepare for future environments where data links cannot be taken for granted, commanders must be prepared to give all subordinates, human and machine, wide latitude to operate, which is only afforded by mission command. Many systems will progress from a man “in” the loop (with the person integral to the functioning), to a man “on” the loop (where the person oversees the system and executes command by negation), and then to complete autonomy. In the future, fully autonomous systems may collaborate with one another across a given echelon and solve problems based on the parameters communicated to them as commander’s intent (swarms would fall into this category). However, it may go even further. Mission command calls for adaptable leaders at every level; what if at some level the leaders are no longer people but machines? It is not hard to imagine a forward deployed autonomous system tasking its own subordinates (fellow machines), particularly in scenarios where there is no available bandwidth to allow backhaul communications or enable detailed control from afar. In these cases, mission command will not just be the preferred option, it will be the only option. This reliance on mission command may be seen as a cultural shift, but in reality, it is a return to the Navy’s cultural roots.
Back to Basics
Culturally, the Navy should be well-suited to embrace the mission command model to employ autonomous systems. Traditionally once a ship passed over the horizon there was little if any communication for extended periods of time due to technological limitations. This led to a culture of mission command: captains were given basic orders and an overall intent; the rest was up to them. Indeed, captains might act as ambassadors and conduct diplomacy and other business on behalf of the government in remote areas with little direct guidance.2 John Paul Jones himself stated that “it often happens that sudden emergencies in foreign waters make him [the Naval Officer] the diplomatic as well as the military representative of his country, and in such cases he may have to act without opportunity of consulting his civic or ministerial superiors at home, and such action may easily involve the portentous issue of peace or war between great powers.”3 This is not to advocate that autonomous systems will participate in diplomatic functions, but it does illustrate the longstanding Navy precedent for autonomy of subordinate units.
Another factor in support of the Navy favoring mission command is that the physics of the operating environment may demand it. For example, the physical properties of the undersea domain prohibit direct, routine, high-bandwidth communication with submerged platforms. This is the case with submarines and is being applied to UUVs by extension. This has led to extensive development of autonomous underwater vehicles (AUVs) vice remotely operated ones; AUVs clearly favor mission command.
Finally, the Navy’s culture of decentralized command is the backbone of the Composite Warfare Commander (CWC) construct. CWC is essentially an expression of mission command. Just as technology (the telegraph cable, wireless, and global satellite communication) has afforded the means of detailed control and micromanagement, it has also increased the speed of warfighting, necessitating decentralized execution. Command by negation is the foundation of CWC, and has been ingrained in the Navy’s officer corps for decades. Extending this mindset to autonomous systems will be key to realizing their full capabilities.
This begs the question: how does one train senior commanders who rose through the ranks during the age of continuous connectivity to thrive in a world of autonomous systems where detailed control is not an option? For a start, they could adopt the mindset of General Norman Schwarzkopf, who described how hard it was to resist interfering with his subordinates:
“I desperately wanted to do something, anything, other than wait, yet the best thing I could do was stay out of the way. If I pestered my generals I’d distract them: I knew as well as anyone that commanders on the battlefield have more important things to worry about than keeping higher headquarters informed…”4
That said, even while restraining himself, at the height of OPERATION DESERT STORM, his U.S. Central Command used more than 700,000 telephone calls and 152,000 radio messages per day to coordinate the actions of their subordinate forces. In contrast, during the Battle of Trafalgar in 1805, Nelson used only three general tactical flag-hoist signals to maneuver the entire British fleet.5
Commanders must learn to be satisfied with the ambiguity inherent in mission command. They must become comfortable clearly communicating their intent and mission requirements, whether tasking people or autonomous systems. Again, there isn’t a choice; the Navy’s adversaries are investing in A2/AD capabilities that explicitly target the means that make detailed control possible. Furthermore, the ambiguity and complexity of today’s operating environments prohibit “a priori” composition of complete and perfect instructions.
Placing commanders into increasingly complex and ambiguous situations during training will push them toward mission command, where they will have to trust subordinates closer to the edge who will be able to execute based on commander’s intent and their own initiative. General Dempsey, former Chairman of the Joint Chiefs of Staff, stressed training that presented commanders with fleeting opportunities and rewarding those who seized them in order to encourage commanders to act in the face of uncertainty.
Familiarization training with autonomous systems could take place in large part via simulation, where commanders interact with the actual algorithms and rehearse at a fraction of the cost of executing a real-world exercise. In this setting, commanders could practice giving mission type orders and translating them for machine understanding. They could employ their systems to failure, analyze where they went wrong, and learn to adjust their level of supervision via multiple iterations. This training wouldn’t be just a one-way evolution; the algorithms would also learn about their commander’s preferences and thought process by finding patterns in their actions and thresholds for their decisions. Through this process, the autonomous system would understand even more about commander’s intent should it need to act alone in the future. If the autonomous system will be in a position to task its own robotic subordinates, that algorithm would be demonstrated so the commander understands how the system may act (which will have incorporated what it has learned about how its commander commands).
With this in mind, while it may seem trivial, consideration must be made for the fact that future autonomous systems may have a detailed algorithmic model of their commander’s thought process, “understand” his intent, and “know” at least a piece of “the big picture.” As such, in the future these systems cannot simply be considered disposable assets performing the dumb, dirty, dangerous work that exempt a human from having to go in harm’s way. They will require significant anti-tamper capabilities to prevent an adversary from extracting or downloading this valuable information if they are somehow taken or recovered by the enemy. Perhaps they could even be armed with algorithms to “resist” exploitation or give misleading information.
The Way Ahead
Above all, commanders will need to establish the same trust and confidence in autonomous systems that they have in manned systems and human operators.6 Commanders trust manned systems, even though they are far from infallible. This came to international attention with the airstrike on the Medecins Sans Frontieres hospital operating in Kunduz, Afghanistan. As this event illustrated, commanders must acknowledge the potential for human error, put mitigation measures in place where they can, and then accept a certain amount of risk. In the future, advances in machine learning and artificial intelligence will yield algorithms that far exceed human processing capabilities. Autonomous systems will be able to sense, process, coordinate, and act faster than their human counterparts. However, trust in these systems will only come from time and experience, and the way to secure that is to mainstream autonomous systems into exercises. Initially these opportunities should be carefully planned and executed, not just added in as an afterthought. For example, including autonomous systems in a particular Fleet Battle Experiment solely to check a box that they were used raises the potential for negative training, where the observers see the technology fail due to ill-conceived employment. As there may be limited opportunities to “win over” the officer corps, this must be avoided. Successfully demonstrating the capabilities (and the legitimate limitations) of autonomous systems is critical. Increased use over time will ensure maximum exposure to future commanders, and will be key to widespread adoption and full utilization.
The Navy must return to its roots and rediscover mission command in order to fully leverage the potential of autonomous systems. While it may make commanders uncomfortable, it has deep roots in historic practice and is a logical extension of existing doctrine. Former General Dempsey wrote that mission command “must pervade the force and drive leader development, organizational design and inform material acquisitions.”7 Taking this to heart and applying it across the board will have profound and lasting impacts as the Navy sails into the era of autonomous systems.

The following two-part series discusses the command and control of future autonomous systems. Part 1 describes how we have arrived at the current tendency towards detailed control. Part 2 proposes how to refocus on mission command.
In recent years, the U.S. Navy’s unmanned vehicles have achieved a number of game-changing “firsts.” The X-47B Unmanned Combat Air System (UCAS) executed the first carrier launch and recovery in 2013, first combined manned/unmanned carrier operations in 2014, and first aerial refueling in 2015.1 In 2014, the Office of Naval Research demonstrated the first swarm capability for Unmanned Surface Vehicles (USV).2 In 2015, the NORTH DAKOTA performed the first launch and recovery of an Unmanned Underwater Vehicle (UUV) from a submarine during an operational mission.3 While these successes may represent the vanguard of a revolution in military technology, the larger revolution in military affairs will only be possible with the optimization of the command and control concepts associated with these systems. Regardless of specific mode (air, surface, or undersea), Navy leaders must fully embrace mission command to fully realize the power of these capabilities.
“Unmanned” systems are not necessarily new. The U.S. Navy’s long history includes the employment of a variety of such platforms. For example, in 1919, Coast Battleship #4 (formerly USS IOWA (BB-1)) became the first radio-controlled target ship to be used in a fleet exercise.4 During World War II, participation in an early unmanned aircraft program called PROJECT ANVIL ultimately killed Navy Lieutenant Joe Kennedy (John F. Kennedy’s older brother), who was to parachute from his bomb-laden aircraft before it would be guided into a German target by radio-control.5 In 1946, F6F Hellcat fighters were modified for remote operation and employed to collect data during the OPERATION CROSSROADS atomic bomb tests at Bikini.6 These Hellcat “drones” could be controlled by another aircraft acting as the “queen” (flying up to 30 miles away). These drones were even launched from the deck of an aircraft carrier (almost 70 years before the X-47B performed that feat).
However, the Navy’s achievements over the last few years were groundbreaking because the platforms were autonomous (i.e. controlled by machine, not remotely operated by a person). The current discussion of autonomy frequently revolves around the issues of ethics and accountability. Is it ethical to imbue these machines with the authority to use lethal force? If the machine is not under direct human control but rather evaluating for itself, who is responsible for its decisions and actions when faced with dilemmas? Much has been written about these topics, but there is a related and less discussed question: what sort of mindset shift will be required for Navy leaders to employ these systems to their full potential?
Command, Control, and Unmanned Systems
According to Naval Doctrine Publication 6 – Command and Control (NDP 6), “a commander commands by deciding what must be done and exercising leadership to inspire subordinates toward a common goal; he controls by monitoring and influencing the action required to accomplish what must be done.”7 These enduring concepts have new implications in the realm of unmanned systems. For example, while a commander can assign tasks to any subordinate (human or machine), “inspiring subordinates” has varying levels of applicability based on whether his units consist of “remotely piloted” aircraft (where his subordinates are actual human pilots) or autonomous systems (where the “pilot” is an algorithm controlling a machine). “Command” also includes establishing intent, distributing guidance on allocation of roles, responsibilities, and resources, and defining constraints on actions.8 On one hand, this could be straightforward with autonomous systems as this guidance could be translated into a series of rules and parameters that define the mission and rules of engagement. One would simply upload the mission and deploy the vehicle, which would go out and execute, possibly reporting in for updates but mostly operating on its own, solving problems along the way. On the other hand, in the absence of instructions that cover every possibility, an autonomous system is only as good as the internal algorithms that control it. Even as machine learning drastically improves and advanced algorithms are developed from extensive “training data,” an autonomous system may not respond to novel and ambiguous situations with the same judgment as a human. Indeed, one can imagine a catastrophic military counterpart to the 2010 stock market “flash crash,” where high-frequency trading algorithms designed to act in accordance with certain, pre-arranged criteria did not understand context and misread the situation, briefly erasing $1 trillion in market value.9
“Control” includes the conduits and feedback from subordinates to their commander that allow them to determine if events are on track or to adjust instructions as necessary. This is reasonably straightforward for a remotely piloted aircraft with a constant data link between platform and operator, such as the ScanEagle or MQ-8 Fire Scout unmanned aerial systems. However, a fully autonomous system may not be in positive communication. Even if it is ostensibly intended to remain in communication, feedback to the commander could be limited or non-existent due to emissions control (EMCON) posture or a contested electromagnetic (EM) spectrum.
Mission Command and Unmanned Systems
In recent years, there has been a renewed focus across the Joint Force on the concept of “mission command.” Mission command is defined as “the conduct of military operations through decentralized execution based upon mission-type orders,” and it lends itself well to the employment of autonomous systems.10 Joint doctrine states:
“Mission command is built on subordinate leaders at all echelons who exercise disciplined initiative and act aggressively and independently to accomplish the mission. Mission-type orders focus on the purpose of the operation rather than details of how to perform assigned tasks. Commanders delegate decisions to subordinates wherever possible, which minimizes detailed control and empowers subordinates’ initiative to make decisions based on the commander’s guidance rather than constant communications.”11
Mission command for an autonomous system would require commanders to clearly confer their intent, objectives, constraints, and restraints in succinct instructions, and then rely on the “initiative” of said system. While this decentralized arrangement is more flexible and better suited to deal with ambiguity, it opens the door to unexpected or emergent behavior in the autonomous system. (Then again, emergent behavior is not confined to algorithms, as humans may perform in unexpected ways too.)
In addition to passing feedback and information up the chain of command to build a shared understanding of the situation, mission command also emphasizes horizontal flow across the echelon between the subordinates. Since it relies on subordinates knowing the intent and mission requirements, mission command is much less vulnerable to disruption than detailed means of command and control.
However, some commanders today do not fully embrace mission command with human subordinates, much less feel comfortable delegating trust to autonomous systems. They issue explicit instructions to subordinates in a highly-centralized arrangement, where volumes of information flow up and detailed orders flow down the chain of command. This may be acceptable in deliberate situations where time is not a major concern, where procedural compliance is emphasized, or where there can be no ambiguity or margin for error. Examples of unmanned systems suitable to this arrangement include a bomb disposal robot or remotely piloted aircraft that requires constant intervention and re-tasking, possibly for rapid repositioning of the platform for a better look at an emerging situation or better discrimination between friend and foe. However, this detailed control does not “function well when the vertical flow of information is disrupted.”12 Furthermore, when it comes to autonomous systems, such detailed control will undermine much of the purpose of having an autonomous system in the first place.
A fundamental task of the commander is to recognize which situations call for detailed control or mission command and act appropriately. Unfortunately, the experience gained by many commanders over the last decade has introduced a bias towards detailed control, which will hamstring the potential capabilities of autonomous systems if this tendency is not overcome.
The American military has enjoyed major advantages in recent conflicts due to global connectivity and continuous communications. However, this has redefined expectations and higher echelons increasingly rely on detailed control (for manned forces, let alone unmanned ones). Senior commanders (or their staffs) may levy demands to feed a seemingly insatiable thirst for information. This has led to friction between the echelons of command, and in some cases this interaction occurs at the expense of the decision-making capability of the unit in the field. Subordinate staff watch officers may spend more time answering requests for information and “feeding the beast” of higher headquarters than they spend overseeing their own operations.
It is understandable why this situation exists today. The senior commander (with whom responsibility ultimately resides) expects to be kept well-informed. To be fair, in some cases a senior commander located at a fusion center far from the front may have access to multiple streams of information, giving them a better overall view of what is going on than the commander actually on the ground. In other cases, it is today’s 24-hour news cycle and zero tolerance for mistakes that have led senior commanders to succumb to the temptation to second-guess their subordinates and micromanage their units in the field. A compounding factor that may be influencing commanders in today’s interconnected world is “Fear of Missing Out” (FoMO), which is described by psychologists as apprehension or anxiety stemming from the availability of volumes of information about what others are doing (think social media). It leads to a strong, almost compulsive desire to stay continually connected. 13
Whatever the reason, this is not a new phenomenon. Understanding previous episodes when leadership has “tightened the reins” and the subsequent impacts is key to developing a path forward to fully leverage the potential of autonomous systems.
Veering Off Course
The recent shift of preference away from mission command toward detailed control appears to echo the impacts of previous advances in the technology employed for command and control in general. For example, when speaking of his service with the U.S. Asiatic Squadron and the introduction of the telegraph before the turn of the 20th century, Rear Admiral Caspar Goodrich lamented “Before the submarine cable was laid, one was really somebody out there, but afterwards one simply became a damned errand boy at the end of a telegraph wire.”14
Later, the impact of wireless telegraphy proved to be a mixed blessing for commanders at sea. Interestingly, the contrasting points of view clearly described how it would enable micromanagement; the difference in opinion was whether this was good or bad. This was illustrated by two 1908 newspaper articles regarding the introduction of wireless in the Royal Navy. One article extolled its virtues, describing how the First Sea Lord in London could direct all fleet activities “as if they were maneuvering beneath his office windows.”15 The other article described how those same naval officers feared “armchair control… by means of wireless.”16 In century-old text that could be drawn from today’s press, the article quoted a Royal Navy officer:
“The paramount necessity in the next naval war will be rapidity of thought and of execution…The innovation is causing more than a little misgiving among naval officers afloat. So far as it will facilitate the interchange of information and the sending of important news, the erection of the [wireless] station is welcomed, but there is a strong fear that advantage will be taken of it to interfere with the independent action of fleet commanders in the event of war.”
Military historian Martin van Creveld related a more recent lesson of technology-enabled micromanagement from the U.S. Army. This time the technology in question was the helicopter, and its widespread use by multiple echelons of command during Viet Nam drove the shift away from mission command to detailed control:
“A hapless company commander engaged in a firefight on the ground was subjected to direct observation by the battalion commander circling above, who was in turn supervised by the brigade commander circling a thousand or so feet higher up, who in his turn was monitored by the division commander in the next highest chopper, who might even be so unlucky as to have his own performance watched by the Field Force (corps) commander. With each of these commanders asking the men on the ground to tune in his frequency and explain the situation, a heavy demand for information was generated that could and did interfere with the troops’ ability to operate effectively.”17
However, not all historic shifts toward detailed control are due to technology; some are cultural. For example, leadership had encroached so much on the authority of commanders in the days leading up to World War II that Admiral King had to issue a message to the fleet with the subject line “Exercise of Command – Excess of Detail in Orders and Instructions,” where he voiced his concern. He wrote that the:
“almost standard practice – of flag officers and other group commanders to issue orders and instructions in which their subordinates are told how as well as what to do to such an extent and in such detail that the Custom of the service has virtually become the antithesis of that essential element of command – initiative of the subordinate.”18
Admiral King attributed this trend to several cultural reasons, including anxiety of seniors that any mistake of a subordinate be attributed to the senior and thereby jeopardize promotion, activities of staffs infringing on lower echelon functions, and the habit and expectation of detailed instructions from junior and senior alike. He went on to say that they were preparing for war, when there would be neither time nor opportunity for this method of control, and this was conditioning subordinate commanders to rely on explicit guidance and depriving them from learning how to exercise initiative. Now, over 70 years later, as the Navy moves forward with autonomous systems the technology-enabled and culture-driven drift towards detailed control is again becoming an Achilles heel.

In 2018 the United States remains engaged worldwide. The 2017 National Security Strategy addresses the wide-range of threats to the security and prosperity of United States.1 These threats range from high-end peer competitors such as China and Russia, to rogue regimes such as North Korea and Iran, to the ongoing threat of terrorism represented by such groups as ISIL. In a preview of the National Security Strategy at the December 2017 Reagan National Defense Forum, National Security Advisor General H.R. McMaster highlighted these threats and reconfirmed the previous administration’s “4+1” strategy, naming the four countries – Russia, China, Iran and North Korea—and the “+1” — terrorists, particularly ISIL — as urgent threats that the United States must deal with today.2
The U.S. military is dealing with this threat landscape by deploying forces worldwide at an unprecedented rate. And in most cases, it is naval strike forces, represented by carrier strike groups centered on nuclear-powered aircraft carriers, and expeditionary strike groups built around large-deck amphibious ships, that are the forces of choice for dealing with crises worldwide.
For decades, when a crisis emerged anywhere on the globe, the first question a U.S. president asked was, “Where are the carriers?” Today, that question is still asked, but increasingly, the question has morphed into, “Where are the expeditionary strike groups?” The reasons for this focus on expeditionary strike groups are clear. These naval expeditionary formations have been the ones used extensively for a wide-array of missions short of war, from anti-piracy patrols, to personnel evacuation, to humanitarian assistance and disaster relief. And where tensions lead to hostilities, these forces are the only ones that give the U.S. military a forcible entry option.
During the past decade-and-a-half of wars in the Middle East and South Asia, the U.S. Marine Corps was used extensively as a land force and did not frequently deploy aboard U.S. Navy amphibious ships. Now the Marine Corps is largely disengaged from those conflicts and is, in the words of a former commandant of the U.S. Marine Corps, “Returning to its amphibious roots.”3 As this occurs, the Navy-Marine Corps team is looking to new technology to complement and enhance the capabilities its amphibious ships bring to the fight.
Because of their “Swiss Army Knife” utility, U.S. naval expeditionary forces have remained relatively robust even as the size of the U.S. Navy has shrunk from 594 ships in 1987 to 272 ships in early 2018. Naval expeditionary strike groups comprise a substantial percentage of the U.S. Navy’s current fleet. And the blueprint for the future fleet the U.S. Navy is building maintains, and even increases, that percentage of amphibious ships.4
However, ships are increasingly expensive and U.S. Navy-Marine Corps expeditionary forces have been proactive in looking to new technology to add capability to their ships. One of the technologies that offer the most promise in this regard is that of unmanned systems. The reasons for embracing unmanned systems stem from their ability to reduce the risk to human life in high-threat areas, to deliver persistent surveillance over areas of interest, and to provide options to warfighters that derive from the inherent advantages of unmanned technologies—especially their ability to operate autonomously.
The importance of unmanned systems to the U.S. Navy’s future has been highlighted in a series of documents, ranging from the 2015 A Cooperative Strategy for 21st Century Seapower, to the 2016 A Design for Maintaining Maritime Superiority, to the 2017 Chief of Naval Operations’ The Future Navy white paper. The Future Navy paper presents a compelling case for the rapid integration of unmanned systems into the Navy Fleet, noting, in part:
“There is no question that unmanned systems must also be an integral part of the future fleet. The advantages such systems offer are even greater when they incorporate autonomy and machine learning….Shifting more heavily to unmanned surface, undersea, and aircraft will help us to further drive down unit costs.”5
The U.S. Navy’s commitment to and growing dependence on unmanned systems is also seen in the Navy’s official Force Structure Assessment of December 2016, as well as in a series of “Future Fleet Architecture Studies.” In each of these studies—one by the Chief of Naval Operations staff, one by the MITRE Corporation, and one by the Center for Strategic and Budgetary Assessments—the proposed Navy future fleet architecture had large numbers of air, surface, and subsurface unmanned systems as part of the Navy force structure. Indeed, these reports highlight the fact that the attributes unmanned systems can bring to the U.S. Navy Fleet circa 2030 have the potential to be truly transformational.6
The Navy Project Team, Report to Congress: Alternative Future Fleet Platform Architecture Study is an example of the Navy’s vision for the increasing use of unmanned systems. This study notes that under a distributed fleet architecture, ships would deploy with many more unmanned surface (USV) and air (UAV) vehicles, and submarines would employ more unmanned underwater vehicles (UUVs). The distributed Fleet would also include large, self-deployable independent USVs and UUVs, increasing unmanned deployed presence to approximately 50 platforms.
This distributed Fleet study calls out specific numbers of unmanned systems that would complement the manned platforms projected to be part of the U.S. Navy inventory by 2030:
255 Conventional take-off UAVs
157 Vertical take-off UAVs
88 Unmanned surface vehicles
183 Medium unmanned underwater vehicles
48 Large unmanned underwater vehicles
By any measure the number of air, surface, and subsurface unmanned vehicles envisioned in the Navy alternative architecture studies represents not only a step-increase in the number of unmanned systems in the Fleet today, but also vastly more unmanned systems than current Navy plans call for. But it is one thing to state the aspiration for more unmanned systems in the Fleet, and quite another to develop and deploy them. There are compelling reasons why naval expeditionary forces have been proactive in experimenting with emerging unmanned systems.
Testing and Evaluating Unmanned Systems
While the U.S. Navy and Marine Corps have embraced unmanned systems of all types into their force structures, and a wide-range of studies looking at the makeup of the Sea Services in the future have endorsed this shift, it is the Navy-Marine Corps expeditionary forces that have been the most active in evaluating a wide variety of unmanned systems in various exercises, experiments, and demonstrations. Part of the reason for this accelerated evaluation of emerging unmanned systems is the fact that, unlike carrier strike groups that have access to unmanned platforms such as MQ-4C Triton and MQ-8 Fire Scout, expeditionary strike groups are not similarly equipped.
While several such exercises, experiments, and demonstrations occurred in 2017, two of the most prominent, based on the scope of the events, as well as the number of new technologies introduced, were the Ship-to-Shore Maneuver Exploration and Experimentation (S2ME2) Advanced Naval Technology Exercise (ANTX), and Bold Alligator 2017. These events highlighted the potential of unmanned naval systems to be force-multipliers for expeditionary strike groups.
S2ME2 ANTX provided an opportunity to demonstrate emerging, innovative technology that could be used to address gaps in capabilities for naval expeditionary strike groups. As there are few missions that are more hazardous to the Navy-Marine Corps team than putting troops ashore in the face of a prepared enemy force, the experiment focused specifically on exploring the operational impact of advanced unmanned maritime systems on the amphibious ship-to-shore mission.
For the amphibious assault mission, UAVs are useful—but are extremely vulnerable to enemy air defenses. UUVs are useful as well, but the underwater medium makes control of these assets at distance problematic. For these reasons, S2ME2 ANTX focused heavily on unmanned surface vehicles to conduct real-time ISR (intelligence, surveillance, and reconnaissance) and IPB (intelligence preparation of the battlespace) missions. These are critical missions that have traditionally been done by our warfighters, but ones that put them at extreme risk.
In an October 2017 interview with U.S. Naval Institute News, the deputy assistant secretary of the Navy for research, development, test and evaluation, William Bray, stressed the importance of using unmanned systems in the ISR and IPB roles:
“Responding to a threat today means using unmanned systems to collect data and then delivering that information to surface ships, submarines, and aircraft. The challenge is delivering this data quickly and in formats allowing for quick action.”7
During the assault phase of S2ME2 ANTX, the expeditionary commander used a USV to thwart enemy defenses. For this event, he used an eight-foot man-portable MANTAS USV (one of a family of stealthy, low profile, USVs) that swam undetected into the “enemy harbor” (the Del Mar Boat Basin on the Southern California coast), and relayed information to the amphibious force command center using its TASKER C2 system. Once this ISR mission was complete, the MANTAS USV was driven to the surf zone to provide IPB on obstacle location, beach gradient, water conditions and other information crucial to planners.
Carly Jackson, SPAWAR Systems Center Pacific’s director of prototyping for Information Warfare and one of the organizers of S2ME2, explained the key element of the exercise was to demonstrate new technology developed in rapid response to real-world problems facing the Fleet:
“This is a relatively new construct where we use the Navy’s organic labs and warfare centers to bring together emerging technologies and innovation to solve a very specific fleet force fighting problem. It’s focused on ‘first wave’ and mainly focused on unmanned systems with a big emphasis on intelligence gathering, surveillance, and reconnaissance.”8
The CHIPS interview article discussed the technologies on display and in demonstration at the S2ME2 ANTX event, especially networked autonomous air and maritime vehicles and ISR technologies. Tracy Conroy, SPAWAR Systems Center Pacific’s experimentation director, noted, “The innovative technology of unmanned vehicles offers a way to gather information that ultimately may help save lives. We take less of a risk of losing a Marine or Navy SEAL.”
S2ME2 ANTX was a precursor to Bold Alligator 2017, the annual Navy-Marine Corps expeditionary exercise. Bold Alligator 2017 was a live, scenario-driven exercise designed to demonstrate maritime and amphibious force capabilities, and was focused on planning and conducting amphibious operations, as well as evaluating new technologies that support the expeditionary force.9
Bold Alligator 2017 encompassed a substantial geographic area in the Virginia and North Carolina OPAREAS. The mission command center was located at Naval Station Norfolk, Virginia. The amphibious force and other units operated eastward of North and South Onslow Beaches, Camp Lejeune, North Carolina. For the littoral mission, some expeditionary units operated in the Intracoastal Waterway near Camp Lejeune.
The Bold Alligator 2017 scope was modified in the wake of Hurricanes Harvey, Irma and Maria, as many of the assets scheduled to participate were used for humanitarian assistance and disaster relief. The exercise featured a smaller number of amphibious forces but did include a carrier strike group.10 The 2nd Marine Expeditionary Brigade (MEB) orchestrated events and was embarked aboard USS Arlington (LPD-24), USS Fort McHenry (LSD-43), and USS Gunston Hall (LSD-44).
The 2nd MEB used a large (12-foot) MANTAS USV, equipped with a Gyro Stabilized SeaFLIR230 EO/IR Camera and a BlueView M900 Forward Looking Imaging Sonar to provide ISR and IPB for the amphibious assault. The sonar was employed to provide bottom imaging of the surf zone, looking for objects and obstacles—especially mine-like objects—that could pose a hazard to the landing craft–LCACs and LCUs–as they moved through the surf zone and onto the beach.
The early phases of Bold Alligator 2017 were dedicated to long-range reconnaissance. Operators at exercise command center at Naval Station Norfolk drove the six-foot and 12-foot MANTAS USVs off North and South Onslow Beaches, as well as up and into the Intracoastal Waterway. Both MANTAS USVs streamed live, high-resolution video and sonar images to the command center. The video images showed vehicles, personnel, and other objects on the beaches and in the Intracoastal Waterway, and the sonar images provided surf-zone bottom analysis and located objects and obstacles that could provide a hazard during the assault phase.
Bold Alligator 2017 underscored the importance of surface unmanned systems to provide real-time ISR and IPB early in the operation. This allowed planners to orchestrate the amphibious assault to ensure that the LCACs or LCUs passing through the surf zone and onto the beach did not encounter mines or other objects that could disable—or even destroy—these assault craft. Providing decision makers not on-scene with the confidence to order the assault was a critical capability and one that will likely be evaluated again in future amphibious exercises such as RIMPAC 2018, Valiant Shield 2018, Talisman Saber 2018, Bold Alligator 2018 and Cobra Gold, among others.
Navy Commitment to Unmanned Maritime Systems
One of the major challenges to the Navy making a substantial commitment to unmanned maritime systems is the fact that they are relatively new and their development has been “under the radar” for all but a few professionals in the science and technology (S&T), research and development (R&D), requirements, and acquisition communities. This lack of familiarity creates a high bar for unmanned naval systems in particular. A DoD Unmanned Systems Integrated Roadmap provided a window into the magnitude of this challenge:
“Creation of substantive autonomous systems/platforms within each domain will create resourcing and leadership challenges for all the services, while challenging their respective warfighter culture as well…Trust of unmanned systems is still in its infancy in ground and maritime systems….Unmanned systems are still a relatively new concept….As a result; there is a fear of new and unproven technology.”11
In spite of these concerns—or maybe because of them—the Naval Sea Systems Command and Navy laboratories have been accelerating the development of USVs and UUVs. The Navy has partnered with industry to develop, field, and test a family of USVs and UUVs such as the Medium Displacement Unmanned Surface Vehicle (“Sea Hunter”), MANTAS next-generation unmanned surface vessels, the Large Displacement Unmanned Underwater Vehicle (LDUUV), and others.
Indeed, this initial prototype testing has been so successful that the Department of the Navy has begun to provide increased support for USVs and UUVs and has established program guidance for many of these systems important to the Navy and Marine Corps. This programmatic commitment is reflected in the 2017 Navy Program Guide as well as in the 2017 Marine Corps Concepts and Programs publications. Both show a commitment to unmanned systems programs.12
In September 2017, Captain Jon Rucker, the program manager of the Navy program office (PMS-406) with stewardship over unmanned maritime systems (unmanned surface vehicles and unmanned underwater vehicles), discussed his programs with USNI News. The title of the article, “Navy Racing to Test, Field, Unmanned Maritime Vehicles for Future Ships,” captured the essence of where unmanned maritime systems will fit in tomorrow’s Navy, as well as the Navy-after-next. Captain Rucker shared:
“In addition to these programs of record, the Navy and Marine Corps have been testing as many unmanned vehicle prototypes as they can, hoping to see the art of the possible for unmanned systems taking on new mission sets. Many of these systems being tested are small surface and underwater vehicles that can be tested by the dozens at tech demonstrations or by operating units.”13
While the Navy is committed to several programs of record for large unmanned maritime systems such as the Knifefish UUV, the Common Unmanned Surface Vehicle (CUSV), the Large Displacement UUV (LDUUV) and Extra Large UUV (XLUUV), and the Anti-Submarine Warfare Continuous Trail Unmanned Vessel (ACTUV) vehicle (since renamed the Medium Displacement USV [MDUSV] and also called Sea Hunter), the Navy also sees great potential in expanding the scope of unmanned maritime systems testing:
“Rucker said a lot of the small unmanned vehicles are used to extend the reach of a mission through aiding in communications or reconnaissance. None have become programs of record yet, but PMS 406 is monitoring their development and their participation in events like the Ship-to-Shore Maneuver Exploration and Experimentation Advanced Naval Technology Exercise, which featured several small UUVs and USVs.”14
The ship-to-shore movement of an expeditionary assault force remains the most hazardous mission for any navy. Real-time ISR and IPB will spell the difference between victory and defeat. For this reason, the types of unmanned systems the Navy and Marine Corps should acquire are those systems that directly support our expeditionary forces. This suggests a need for unmanned surface systems to complement expeditionary naval formations. Indeed, USVs might well be the bridge to the Navy-after-next.
