Unmanned-Centric Force Structure

Alternative Naval Force Structure Week

By Javier Gonzalez 

The U.S. Navy is currently working on a new Fleet Structure Assessment, the results of which will eventually help inform the long-term force structure goals of the Navy’s 30-year shipbuilding plan. This ongoing analysis was generated due to the realization that some of the assumptions used to develop the current goal of 308 ships have changed significantly since its proposal in 2014. The Russian resurgence and China’s rapid military buildup defied expectations, and a review of the Navy’s force structure was absolutely warranted. The conundrum and implied assumption, with this or similar future force structure analyses, is that the Navy must have at least a vague understanding of an uncertain future. However, there is a better way to build a superior and more capable fleet—by continuing to build manned ships based on current and available capabilities while also fully embracing optionality (aka flexibility and adaptability) in unmanned systems. Additionally, and perhaps the better argument, is that a new, unmanned-centric fleet can be more affordable while maintaining its relevance over the expected service life.

Optionality

A relevant fleet is one that is robust, flexible, and adaptable—one that embraces optionality to anticipate uncertain and changing requirements. The author Nassim Taleb describes optionality as “the property of asymmetric upside with correspondingly limited downside.” The implication here is to clearly identify which options will provide the best ability to achieve this “asymmetric upside.” Systems such as the vertical launch system provide a certain degree of flexibility by allowing for the rapid fielding of any weapons that fit inside a missile. In addition, the concepts of modularity (Littoral Combat Ship program), modular hulls, containers interfaces, flexible infrastructures, and electronic modular enclosures are other examples of the Navy’s explicit efforts to add flexibility and adaptability into the fleet. The upsides of adding flexibility are self-evident—by having options added early in the design process, the Navy can quickly and affordably react to new geo-political situations and adjust to technological innovations. However, adding optionality is not an easy proposition, especially because today’s capabilities fielding process values optimization, affordability, and a discernable return on investment over adaptability and flexibility.

Optimization is contrary to optionality, but it is a main factor in today’s ship design. For instance, space optimization is intuitive—the better optimized a space, given today’s capabilities, the smaller the ship needs to be and, consequently, the more affordable it should be. However, this approach infers a level of certainty and inflexibility to change, contrary to optionality. The reality is that optimization is at times necessary on a manned warship. However, new unmanned system designs can provide a canvas to shift this focus to one that values optionality and takes advantage of uncertainty. The suggestion is to make the long-term investment on the unmanned “bus,” not the capabilities. These new unmanned buses must be designed to maximize power generation, cooling, and space availability. The design also needs a robust command and control system to enable the employment of multiple unmanned systems in a cooperative environment.

Affordable Fleet

The affordability of the fleet is not simply a function of budget availability. In 2014, the Chief of Naval Operations, Adm. Jonathan Greenert, testified to Congress that the Navy needed a 450 ship fleet to meet the global demands by the Combatant Commanders. This 450 ship number is likely better equipped to meet future Combatant Commanders’ needs than the current proposal of a 308 ship Navy. At a minimum, a 450 ship Navy provides more options to fulfill future requirements. However, the current and expected future fiscal environment suggests that building more ships is not an option unless a radical change occurs. Also, the enemy has a crucial vote on the affordability of the fleet. The fall of the USRR can be traced back to the U.S. strategy, in the 1970s and 1980s, to impose great costs on the Soviets by making investments to render their warfighting systems obsolete. This obsolescence created an incentive for the Soviets to make costly investments in an attempt to match the technology introductions by the United States. This strategy’s success was achieved in great part due to the apparent U.S. technological advantage over the Soviets. Today, the United States finds itself in a similar predicament as the Soviets in the Cold War, where technology is leaping in new and unexpected ways and China, in particular, is fielding systems that make many U.S. systems obsolete. The rapid fielding of “game changing” technology by China, such as the first quantum communications satellite or the DF-21D missile, results in a predictable reaction by the DoD to invest in more capable and expensive advancements to counter their efforts. If the Soviets are any indication of the dangers of this strategy, especially if the United States acknowledges that the technological edge over near competitors in the 20th century will no longer be assured, then the United States needs to shift its competitive model to one flexible enough to rapidly and affordably adjust to unforeseen challenges.

 Additionaly, long-term shipbuilding is inherently expensive and dependent on current and mature capabilities. Trying to build a ship with immature technologies can result in unnaceptable acquisition blunders. For instance, the Navy’s next-generation nuclear carrier, CVN-78 Gerard P. Ford, has resulted in massive cost overruns due in great part to the risk incurred in trying to include new and immature technologies into the shipbuilding plan. An unmanned-centric fleet provides the flexibility to value building manned ships based on current and available capabilities while also fully embracing optionality in unmanned systems. An added benefit of having optionality combined with unmanned systems is that it allows for prospective capabilities to be more rapidly prototyped while offering a robust means for experimentation both for technology and future concept of operations development. Unmanned systems could function similarly to a smartphone and its many applications. The benefit of this approach is that it provides an environment with stressors that will allow new technology to fail early and facilitate rapid change, evolution, and dramatically quicken the research and capabilities fielding cycles. The next Fleet Structure Assessment should also embrace optionality by finding the optimal mix of manned and unmanned vessels that will yield an asymmetric upside.

Unmanned-Centric

An unmanned-centric force structure will be dramatically different than today’s Navy, and it will require a departure from the 450 ship manned Navy ideal or the current 308 ship goal. The right mix of manned versus unmanned systems can be derived from a concept of operations that promotes judicious force structure discussions. The basis of this new concept is a fleet with more unmanned systems than manned systems where these platforms are fully integrated. For instance, instead of having a Surface Action Group (SAG) comprised of three manned ships, new SAGs could be comprised of a manned ship and at least two unmanned surface vehicles. Incorporating vehicles like DARPA’s ASW Continuous Trail Unmanned Vessel or General Dynamics’ Fleet-class unmanned surface vessel could add capabilities that will immediately increase lethality and adaptability. In the amphibious realm, the Navy could leverage unmanned platforms as resupply distribution systems for Marines on the beach. This could be of particular importance in a contested environment while supporting multiple fronts in an archipelago-like scenario. Further in the future, instead of having eleven 100,000-ton aircraft carriers, a mix of eight traditional carriers with eight to ten smaller (~40,000 ton) all-unmanned combat air vehicle carriers will provide the flexibility and presence that all Combatant Commanders are desperately seeking.

Presence is about having the right capability, in the right place, at the right time. To accomplish this the Navy will essentially need more assets. A plausible solution could be a force structure where the main employment of unmanned systems will be around unmanned-centric Surface Action Groups as the smallest force package to fulfill theater needs. The current 308 ship Navy plan is structured as follows:

CVNLSCSSCSSNSSGNSSBNAWSCLFSuptTotal
11885248012342934308

CVN – Carrier, LSC – Large Surface Combatants, SSC – Small Surface Combatants, SSN – Fast attack submarines, SSBN – Ballistics Submarines, AWS – Amphibious Warfare Ships, CLF – Combat Logistic Force, Supt – Support vessels.

A future force structure could start with trading large and small surface combatants for a new fleet of Unmanned Vessels. The affordability comes from the added presence afforded by the nature of an unmanned autonomous system and the need for fewer personnel to support their operations. The added capability comes from the introduction of 19 capable Surface Action Groups comprised of a manned ship with two unmanned vessels as depicted below and further explained in table I:

CVNLSCSSCUSVSSNSSBNAWSCLFSuptTotal
118450384812342934340

CVN – Carrier, LSC – Large Surface Combatants, SSC – Small Surface Combatants, USV – Unmanned Surface Vessel, SSN – Fast attack submarines, SSBN – Ballistics Submarines, AWS – Amphibious Warfare Ships, CLF – Combat Logistic Force, Supt – Support vessels.

screenshot_11– Rule of thumb used: 3 ships at home for every one deployed (for repairs, maintenance, training, and other requirements).
-Out of the 140 surface combatants (large and small) proposed in current 308 ship plan, 35 could be deployed at any time (based on rule of thumb).  Assuming 4 carriers deployed with an escort composition of three manned surface combatants per deployed carrier – the Navy could have 23 manned surface combatants available for tasking.
-Based on GAO yearly operational costs of a DDG ($70k per day) and assumed cost of DARPA’s ACTUV  ($15-20k per day) then one DDG is equivalent to 12 USVs (no personnel = affordability). Force structure was determined by trading 4 DDGs to provide 38 USVs. Four less DDGs = 19 very capable Surface Action Groups (a manned ship and two unmanned vessels).

Conclusion

The most important attributes for future force structures are relevance and affordability. This goal can be achieved by pivoting from the traditional to place the emphasis on developing unmanned capable buses that can accommodate all current technologies and have the capacity to flex and adapt to future technologies. Optionality to ship-building and unmanned systems integration can provide the flexibility and adaptability the Navy requires to remain relevant in an uncertain future. The result is a force structure that is more capable and conceptually more affordable. All great plans start with the end in mind – the upcoming Fleet Structure Assessment needs to showcase what the end of the Navy’s 30-year vision looks like. The suggestion is an unmanned-centric, man-led fleet.

Unmanned Systems: A New Era for the U.S. Navy?

By Marjorie Greene

The U.S. Navy’s Unmanned Systems Directorate, or N99, was formally stood up this past September with the focused mission of quickly assessing emerging technologies and applying them to unmanned platforms. The Director of Unmanned Warfare Systems is Rear Adm. Robert Girrier, who was recently interviewed by Scout Warrior, and outlined a new, evolving Navy Drone Strategy.

The idea is to capitalize upon the accelerating speed of computer processing and rapid improvements in the development of autonomy-increasing algorithms; this will allow unmanned systems to quickly operate with an improved level of autonomy, function together as part of an integrated network, and more quickly perform a wider range of functions without needing every individual task controlled by humans. “We aim to harness these technologies. In the next five years or so we are going to try to move from human operated systems to ones that are less dependent on people. Technology is going to enable increased autonomy,” Admiral Girrier told Scout Warrior.

Forward, into Autonomy

Although aerial drones have taken off a lot faster than their maritime and ground-based equivalent, there are some signs that the use of naval drones – especially underwater – is about to take a leap forward. As recently as February this year, U.S. Defense Secretary Ash Carter announced that the Pentagon plans to spend $600 million over the next five years on the development of unmanned underwater systems. DARPA (the Defense Advanced Research Projects Agency) recently announced that the Navy’s newest risk taker is an “unmanned ship that can cross the Pacific.”

Called the Sea Hunter, the vessel is a demonstrator version of an unmanned ship that will run autonomously for 60 – 80 days at a time. Known officially as the Anti-Submarine Warfare Continuous Trail Unmanned Vessel (ACTUV), the program started in 2010, when the defense innovations lab decided to look at what could be done with a large unmanned surface vessel and came up with submarine tracking and trailing. “It is really a mixture of manned-unmanned fleet,” said program manager Scott Littlefield. The big challenge was not related to programming the ship for missions. Rather, it was more basic – making an automated vessel at sea capable of driving safely. DARPA had to be certain the ship would not only avoid a collision on the open seas, but obey protocol for doing so.

As further evidence of the Navy’s progress toward computer-driven drones, the Navy and General Dynamics Electric Boat are testing a prototype of a system called the Universal Launch and Recovery Module that would allow the launch and recovery of unmanned underwater vehicles from the missile tube of a submarine. The Navy is also working with platforms designed to collect oceanographic and hydrographic information and is operating a small, hand-launched drone called “Puma” to provide over-the-horizon surveillance for surface platforms.

Both DARPA and the Office of Naval Research also continue to create more sophisticated Unmanned Aircraft Systems. DARPA recently awarded Phase 2 system integration contracts for its CODE (Collaborative Operations in Denied Environment) program to help the U.S. military’s unmanned aircraft systems (UAS) conduct dynamic, long-distance engagements against highly mobile ground and maritime targets in denied or contested electromagnetic airspace, all while reducing required communication bandwidth and cognitive burden on human supervisors.

CODE’s main objective is to develop and demonstrate the value of collective autonomy, in which UAS could perform sophisticated tasks, both individually and in teams under the supervision of a single human mission commander. The ONR LOCUST Program allows UAVs (Unmanned Aerial Vehicles) to stay in formation with little human control. At a recent demonstration, a single human controller was able to operate up to 32 UAVs.

The Networked Machine…

The principle by which individual UAVs are able to stay in formation with little human control is based on a concept called “swarm intelligence,” which refers to the collective behavior of decentralized, self-organized systems, as introduced by Norbert Wiener in his book, Cybernetics. Building on behavioral models of animal cultures such as the synchronous flocking of birds, he postulated that “self-organization” is a process by which machines – and, by analogy, humans – learn by adapting to their environment.

The flock behavior, or murmuration, of starlings is an excellent demonstration of self-organization. (Video: BBC via YouTube)

Self-organization refers to the emergence of higher-level properties and behaviors of a system that originate from the collective dynamics of that system’s components but are not found in nor are directly deducible from the lower-level properties of the system. Emergent properties are properties of the whole that are not possessed by any of the individual parts making up that whole. The parts act locally on local information and global order emerges without any need for external control. In short, the whole is truly greater than the sum of its parts.

There is also a relatively new concept called “artificial swarm intelligence,” in which there have been attempts to develop human swarms using the internet to achieve a collective, synchronous wisdom that outperforms individual members of the swarm. Still in its infancy, the concept offers another approach to the increasing vulnerability of centralized command and control systems.

Perhaps more importantly, the concept may also allay increasing concerns about the potential dangers of artificial intelligence without a human in the loop. A team of Naval Postgraduate researchers are currently exploring a concept of “network optional warfare” and proposing technologies to create a “mesh network” for independent SAG tactical operations with designated command and control.

…And The Connected Human

Adm. Girrier was quick to point out that the strategy – aimed primarily at enabling submarines, surface ships, and some land-based operations to take advantage of fast-emerging computer technologies — was by no means intended to replace humans. Rather, it aims to leverage human perception and cognitive ability to operate multiple drones while functioning in a command and control capacity. In the opinion of this author, a major issue to be resolved in optimizing humans and machines working together is the obstacle of “information overload” for the human.

Captain Wayne P. Hughes Jr, U.S. Navy (Ret.), a professor in the Department of Operations Research at the Naval Postgraduate School, has already noted the important trend in “scouting” (or ISR) effectiveness. In his opinion, processing information has become a greater challenge than collecting it. Thus, the emphasis must be shifted from the gathering and delivery of information to the fusion and interpretation of information. According to CAPT Hughes, “the current trend is a shift of emphasis from the means of scouting…to the fusion and interpretation of massive amounts of information into an essence on which commanders may decide and act.”

Leaders of the Surface Navy continue to lay the intellectual groundwork for Distributed Lethality – defined as a tactical shift to re-organize and re-equip the surface fleet by grouping ships into small Surface Action Groups (SAGs) and increasing their complement of anti-ship weapons. This may be an opportune time to introduce the concept of swarm intelligence for decentralized command and control. Technologies could still be developed to centralize the control of multiple SAGs designed to counter adversaries in an A2/AD environment. But swarm intelligence technologies could also be used in which small surface combatants would each act locally on local information, with systemic order “emerging” from their collective dynamics.

Conclusion

Yes, technology is going to enable increased autonomy, as noted by Adm. Girrier in his interview with Scout Warrior. But as he said, it will be critical to keep the human in the loop and to focus on optimizing how humans and machines can better work together. While noting that decisions about the use of lethal force with unmanned systems will, according to Pentagon doctrine, be made by human beings in a command and control capacity, we must be assured that global order will continue to emerge with humans in control.

Could Robot Submarines Replace Australia’s Ageing Collins Class Submarines?

This article originally featured on The Conversation. It can be read in its original form here.

By Sean Welsh

The decision to replace Australia’s submarines has been stalled for too long by politicians afraid of the bad media about “dud subs” the Collins class got last century.

Collins class subs deserved criticism in the 1990s. They did not meet Royal Australian Navy (RAN) specifications. But in this century, after much effort, they came good. Though they are expensive, Collins class boats have “sunk” US Navy attack submarines, destroyers and aircraft carriers in exercises.

Now that the Collins class is up for replacement, we have an opportunity to reevaluate our requirements and see what technology might meet them. And just as drones are replacing crewed aircraft in many roles, some military thinkers assume the future of naval war will be increasingly autonomous.

The advantages of autonomy in submarines are similar to those of autonomy in aircraft. Taking the pilot out of the plane means you don’t have to provide oxygen, worry about g-forces or provide bathrooms and meals for long trips.

Taking 40 sailors and 20 torpedoes out of a submarine will do wonders for its range and stealth. Autonomous submarines could be a far cheaper option to meet the RAN’s intelligence, surveillance and reconnaissance (ISR) requirements than crewed submarines.

Submarines do more than sink ships. Naval war is rare but ISR never stops. Before sinking the enemy you must find them and know what they look like. ISR was the original role of drones and remains their primary role today.

Last month, Boeing unveiled a prototype autonomous submarine with long range and high endurance. It has a modular design and could perhaps be adapted to meet RAN ISR requirements.

Boeing is developing a long range autonomous submarine that could have military applications.

Thus, rather than buy 12 crewed submarines to replace the Collins class, perhaps the project could be split into meeting the ISR requirement with autonomous submarines that can interoperate with a smaller number of crewed submarines that sink the enemy.

Future submarines might even be “carriers” for autonomous and semi-autonomous UAVs (unmanned aerial vehicles) and UUVs (unmanned undersea vehicles).

Keeping People on Deck

However, while there may be a role for autonomous submarines in the future of naval warfare, there are some significant limitations to what they can achieve today and in the foreseeable future.

Most of today’s autonomous submarines have short ranges and are designed for very specific missions, such as mine sweeping. They are not designed to sail from Perth to Singapore or Hong Kong, sneak up on enemy ships and submarines, and sink them with torpedoes.

Also, while drone aircraft can be controlled from a remote location, telepiloting is not an option for a long range sub at depth.

The very low frequency radio transceivers in Western Australia used by the Pentagon to signal “boomers” (nuclear-powered, nuclear-armed submarines) in the Indian Ocean have very low transmission rates: only a few hundred bytes per second.

You cannot telepilot a submarine lying below a thermocline in Asian waters from Canberra like you can telepilot a drone flying in Afghanistan with high-bandwidth satellite links from Nevada.

Contemporary telepiloted semi-autonomous submarines are controlled by physical tethers, basically waterproof network cables, when they dive. This limits range to a few kilometers.

Who’s the Captain?

To consider autonomy in the role of sinking the enemy, the RAN would likely want an “ethical governor” to skipper the submarines. This involves a machine making life and death decisions: a “Terminator” as captain so to speak.

This would present a policy challenge for government and a trust issue for the RAN. It would certainly attract protest and raise accountability questions.

On the other hand, at periscope depth, you can telepilot a submarine. To help solve the chronic recruitment problems of the Collins class, the RAN connected them to the internet. If you have a satellite “dongle on the periscope” so the crew can email their loved ones, then theoretically you can telepilot the submarine as well.

That said, if you are sneaking up on an enemy sub and are deep below the waves, you can’t.

Even if you can telepilot, radio emissions directing the sub’s actions above the waves might give away its position to the enemy. Telepiloting is just not as stealthy as radio silence. And stealth is critical to a submarine in war.

Telepiloting also exposes the sub to the operational risks of cyberwarfare and jamming.

There is great technological and political risk in the Future Submarine Project. I don’t think robot submarines can replace crewed submarines but they can augment them and, for some missions, shift risk from vital human crews to more expendable machines.

Ordering nothing but crewed submarines in 2016 might be a bad naval investment.
