Distributed Basing: The Key to Distributed Lethality’s Success in the Western Pacific

The following is a submission from guest author Eric Gomez for CIMSEC’s Distributed Lethality week.

The distributed lethality concept that was unveiled in Proceedings at the start of this year represents a new way of using naval forces against an adversary attempting to deny the U.S. Navy access to a combat area. Simply put, distributed lethality calls for creating hunter-killer surface action groups (SAG) consisting of a handful of surface combatants that conduct offensive anti-submarine and anti-surface operations.

In the Western Pacific, the greatest challenges to the U.S. Navy’s surface fleet are the air, naval, and missile forces of the People’s Republic of China, which are supported by a growing array of surveillance and reconnaissance systems. However, China’s ability to track and target American surface ships is still relatively weak and could be the “Achilles’ heel” of China’s anti-access/area-denial (A2/AD) strategy. Distributed lethality seeks to exploit this surveillance weakness by putting more targets into a combat area, making tracking and targeting a more complex problem.

If implemented as intended, distributed lethality will likely succeed at making it difficult for the Chinese military to target U.S. Navy surface ships that are underway. However, the ports and base facilities in the region that the Navy depends on to keep it surface forces in the fight would be at risk. For example, the naval base at Yokosuka, Japan, the only base west of Hawaii that can repair aircraft carriers, lies within the range of Chinese land-based missiles. Bases that are protected by distance from Chinese attack, such as Guam, are too far away to play a major role in the distributed lethality concept that calls for fast tempo offensive operations.

In order for distributed lethality to work, the U.S. Navy and government must start reaching out to Western Pacific partners to expand American access to naval bases and port facilities. Realistically, “expanded access” would probably look like the Enhanced Defense Cooperation Agreement with the Philippines, or the stationing of Littoral Combat Ships in Singapore. These are not full-fledged U.S. bases, but there is an expanding American military presence that should include more of the surface combatants that are the lynchpin of distributed lethality. The best way to implement the distributed lethality concept in the Western Pacific is through distributed basing, expanding the number of facilities where U.S. surface combatants can be based.

Distributed basing gives strategic heft to the distributed lethality concept in two ways. First, distributed basing increases the credibility of American extended deterrence in the Western Pacific by creating more “tripwires” similar to the token American forces stationed in Berlin during the Cold War. Second, distributed basing raises the costs of Chinese attacks by placing U.S. surface combatants alongside the military equipment of host countries. If the Chinese military wants to inflict a crippling first strike on U.S. Navy surface combatants in port, it will risk destroying the equipment and killing the personnel of another country’s military. This would likely draw that country into military conflict with China, thereby raising the economic, political, and military costs of the Chinese decision to strike.

However, no military decision comes without negative consequences, and it is important to consider the costs or pitfalls of distributed basing. Bases and other facilities will have to be able to withstand attacks. There has been much discussion about hardening U.S. Air Force bases against Chinese missile attacks. Similar hardening efforts or installing the Aegis Ashore missile defense system would be two examples of American efforts to keep a

distributed surface combatant force alive in the opening stages of a conflict. Fully implementing such base defenses will take time and resources, both of which might be in short supply. This could create a “window of opportunity” for Chinese military action in which the distributed lethality concept will be less effective as bases and facilities are upgraded.

Additionally, there is no guarantee that other states will allow the U.S. to implement distributed basing. Even in Japan, a U.S. treaty ally, there is considerable popular opposition to the basing of American forces. An increasingly threatening China could provide a compelling rationale for allowing American warships to be put back into bases and ports, but distributed basing is by no means a political slam dunk.

The distributed lethality concept does provide a new and potentially effective way for the U.S. Navy to respond to A2/AD threats, but more work needs to be done on the logistical side. In order for distributed lethality to be most effective, U.S. surface combatants should be distributed at more locations throughout the Western Pacific. This would enable them to get to their combat areas faster and would present more targets for the Chinese to engage in the early stages of an armed conflict. However, expanding access and distributing surface combatants across more facilities in the Western Pacific will not be easy tasks. Having the U.S. Navy spread across more facilities will not be beneficial unless those facilities can be adequately defended. Bringing many facilities up to an acceptable standard of protection will require an investment of time and resources that create a “window of opportunity” for Chinese action.

Having the distributed lethality concept is a good start because it shows the Navy is thinking creatively about new ways to counter the A2/AD strategy. However, more thinking and writing on the logistics aspect of distributed lethality needs to be done in order for distributed lethality to reach its full potential.

Distributed Endurance: Logistics and Distributed Lethality

The following is a submission by guest author Chris O’Connor for CIMSEC’s Distributed Lethality week.

Distributed lethality is a concept that harkens back to the glory days of the US Navy in the age of sail: small groups of ships with operational autonomy fighting the enemy with their organic firepower and capabilities. Operational autonomy was the default state for ships  until Marconi’s radio set- the lack of instantaneous communication meant that commanders had to make decisions by themselves. Concerning distributed lethality, the lack of communications is imposed upon our ships by enemy communications denial in an A2/AD environment. The parallel does not work in the logistics domain as well- warships then had to fend for themselves logistically, while today, we will have to force a new mode of supply on our ships in order for them to operate independently.

There are some lessons we can learn from how we supported our ships in the past, but there is a big difference in the sustainment modality of the 64-gun USS Bonhomme Richard of Revolutionary War legend and the modern namesake of her captain USS John Paul Jones (DDG-53).

First of all, those ships of sail operated with what is now called an “expeditionary mindset.” They operated with austerity, for threplenishment opportunities were few and far between. Most of our surface combatants are replenished from MSC ships with such frequency that fresh fruits and vegetables are a part of the staple on Carrier Strike Group (CSG) deployers and hard pack ice cream is not uncommon. Life on-board the hunter killer Surface Action Groups (SAGs) will be less comfortable, but it does not have to regress to the days of hard tack and picked herring. Instead, austere life on a modern surface ship life will be closer to that of how submariners live on nuclear attack subs. More canned and from scratch food could be served and valuable storeroom space that is now used for ship’s store items and soda vending could further extend the endurance of a vessel as food storage. Our refrigeration units could be converted to only carry frozen items, yet another adaptation for better food autonomy that sacrifices the comfort of salads and perishable fruit for several more days between replenishment hits.

Ships in the age of sail had carpenters in their crew and bosun’s mates that could repair a large part of what we would call ‘Hull, Mechanical, and Electrical’ systems on today’s warships, using materials that could be collected from almost any port- or from captured enemy ships, for that matter. Shot out rudders, rigging, sails- the prime movers of a ship of the day- could be at least “jury rigged” with organic capabilities on-board. The bridge that modern warships need to come even close to this capability is a suite of additive manufacturing systems that can build replacement parts of many shapes and materials, to include systems that can repair parts by building directly on their surfaces with an additive manufacturing (AM) system. Sailors will need to be able to repair their own systems with these new technologies, introducing an organizational level repair suite that can fix far more than the currently installed machine shops. In the near term, AM will not be the solution to all of our shipboard repair problems, especially on space constrained surface combatants. The state of the technology means that our ships will still depend on logistics assets for at least some of their repair parts, which will tend towards the complex in design, and will be most likely vital for the operation of our critical systems.

The delivery of high priority parts to ships at sea necessitates a solution that departs from our historical parallels. If we are to provide logistical supports to distributed assets in a emission-restricted or denied environment, a family of autonomous replenishment assets needs to be developed. In the “distributed lethality” environment, large, exquisite MH-60 helicopters should not be used to deliver small packages of critical parts (a situation that the author has personally experienced a number of times). These multi-mission aircraft are better utilized prosecuting targets, providing ISR, and acting as communications relays. The crews of the helicopters should also not be put to risk delivering parts where detection in contested airspace would have a fatal outcome. Vertical take-off and landing UAVs (VTUAV) lend themselves perfectly to this mission, but there is not currently a platform in the Navy that is suited for this mission.

The Navy needs to fill this capability gap by changing how VTUAVs are operated from ships and advancing existing technologies to a level that allows for a mature autonomous capability. We have to

operate these systems without flight following; controlled assets are no use to us an environment where communications are not guaranteed. To enable this, such a robotic replenishment asset would have to have “sense and avoid” systems so that they do not collide with other aircraft, ships, or oil platforms as they fly point to point from ship to ship or ship to shore. In addition, these aircraft will have systems that use a combination of EO/IR, LIDAR, and INS to first get in the vicinity of the receiving ship and then land on it without any outside input or control. This is an important difference from our current CONOPs, for there is no UAV that can land on any ship in our inventory by itself; they all require UCARs (UAV Common Automatic Recovery System), SPN radars, or man-in-the-loop input. To be truly useful, logistics missions should be able to be flown to and from any surface ship, as they are with manned helicopters. The all of the above technologies needed for an autonomous logistics UAV currently exist but have not been combined into one dedicated platform. When proven, a family of systems ranging from Fire Scout to optionally manned H-60s to hybrid airships could be employed, stretching a flexible sustainment chain that can leapfrog from asset to asset out to our hunter killer SAGs.

Austerity, additive manufacturing, and robotic replenishment can only take sustainment endurance so far without dealing with the five hundred pound gorilla of energy supply. At sea fuel replenishment will be much rarer if combatant ships operate in environments that make MSC ship operations difficult due to distance or enemy threats. In addition, these oilers might be occupied in other future missions as missile shooters with bolt-on launchers or adaptive force package elements. To start, a greater tolerance for lower levels of shipboard fuel bunkerage needs to be embraced operationally. Fuel cells and batteries need to be added to existing platforms to share the electrical generation burden from the gas turbine generators, so more fuel can be conserved for ship propulsion. The end solution to this problem could be much more radical and needs to be examined in great depth. Unmanned fuel tugs in concert with underwater fuel stations could service our ships, but the full implications of using such systems are far from certain.

“Distributed Lethality” will prove a sea change to how naval forces employ surface assets with significant implications for tactics, command and control methods, and platform employment means. In order for it all to work, we need to be as innovative with our sustainment methods we are in all the other enabling warfare disciplines. The sooner we get started, the more seamless the final package will be.

Distributed Lethality: A Cultural Shift

The following is a submission from guest author James Davenport for CIMSEC’s Distributed Lethality week.

Despite the recent article on Distributed Lethality1 and the paper on Offensive Sea Control2, there is a sense of hesitancy in the surface force in embracing these ideas. The hesitation is understandable. Distributed Lethality and Offensive Sea Control (henceforth referred to as Distributed Lethality for brevity) run counter to recent experience, and they appear to challenge the most successful surface program in history, Aegis, by suggesting that offensive warfare is equal to or greater in importance than the defensive operations the surface force is so well-equipped and trained to perform.

Distributed Lethality cannot succeed without a change in the surface force’s culture. To enable that change in culture the surface force must understand where its bias towards the defensive originates. The surface force must understand why Distributed Lethality is sound military theory. The surface force needs to be reminded that it has embraced Distributed Lethality before to great effect. The surface force must rethink how it views survivability in an anti-access/ area denial (A2/AD) environment. Finally, the surface force must change its culture through training and repeated exposure to the concept of Distributed Lethality.

Institutional Perception of the Surface Force

With the fall of the Soviet Union, the USN’s superiority was unchallenged for more than a decade. The USN became a victim of its own success. Assured of its superiority, the Navy started reducing its offensive flexibility. The USN built thirty-four guided-missile destroyers with no over the horizon anti-ship capability at all and retired the long-range anti-ship version of the Tomahawk missile. There was no challenger to use it, or practice using it, on. The surface force’s focus was squarely on visit, board, search, and seizure and air and missile defense operations.

The focus on air and missile defense operations is reinforced by the superb training on the Aegis Weapon System most Surface Warfare Officers receive at some point in their careers. Aegis Training and Readiness Center in Dahlgren, VA is rightly regarded as a center of 1975028_1481959128698444_800990737_nexcellence for training. Surface Warfare Officers can receive training there three or four times through their career inculcating Surface Warfare Officers in the Aegis culture of excellence. The success of Aegis and its adaptation to the ballistic missile defense mission is a tribute to the partnership between the Navy, the Missile Defense Agency, and our industry partners. No one system has dominated the thinking of the surface force in the way Aegis has.

The result of these influences is a defensive-minded surface force. Many in the surface force perceive their mission as providing defense against small surface vessels, cruise missiles, ballistic missiles, and submarines. In return, the air wing goes on the offensive against ships and aircraft, while the submarine force goes on the offense against threat submarines and ships. This mindset says in order to survive the force has to operate as a whole, while concentrating the majority of the offensive firepower in a small number of submarines and an even smaller number of aircraft carriers and their air wings. This concentration of offensive firepower limits flexibility, reducing the Navy’s ability to operate against anti-access /area denial threats.

The Theory Behind Offensive Sea Control

Recognizing wholesale command of the seas is impractical in the face of A2/AD threats, admirals Rowden, Gumataotao, and Fanta argue for the use of distributed lethality to take control of the seas in key areas in order to project power.1 This is certainly one significant advantage of distributed lethality and offensive sea control. It is not the only advantage, however.

Corbett also recognized it would be impractical to dominate the seas completely, at all times. Corbett does identify a solution; prevent the enemy from securing or controlling the seas by “active defensive operations.”3 In Corbett’s view, sea control is not sitting web_101210-N-2885V-025off the coast of a hostile nation, asserting air, sea, and electromagnetic dominance, while launching strikes ashore. Corbett’s opinion, in more modern terminology, is that sea denial is sufficient.

No matter what it is called, sea denial or sea control, the concept has value. Equipping our surface ships with more offensive capability complicates our adversaries’ planning. A distributed, lethal force must be accounted for, either by devoting resources, to defend against it, to negate it, or by amassing a robust enough force to absorb more losses and still perform their mission. Enough offensive capability may even deter our adversaries from adventurism in the first place.

Distributed Operations

Not only does distributed lethality have value in disrupting and deterring potential adversaries, but it can also play a significant part in defeating them. The bulk of the USN is generally located far from potential hot spots. Only a fraction of the fleet is forward deployed. Furthermore, that fraction is spread across the globe in support of the nation’s interests. The nation’s adversaries have the advantage of being able to operate near their own shores as well as to determining when and where they will strike; in effect, negating the advantages in capability and mass the USN possesses. Thus, at the onset of hostilities the USN will be likely the inferior force, which is not necessarily the disadvantage it may seem, as long as that forward-deployed force is lethal.

Clausewitz argues a force not concentrated at the same place at the same time has an advantage over a force that is concentrated. A concentrated force attacked by a smaller force will suffer disproportionate casualties and suffer disorganization from the attack, as long as the smaller force has reinforcements to press home this advantage.4 Although, the example is tactical in nature, this idea is remarkably similar to the situation the USN finds itself in today and has relevance in a modern operational context. If equipped properly with both offensive capability and mindset, a small number of forward deployed units could inflict disproportionate casualties, while being able to call upon a much larger force assembled from across the globe to administer a coup de grace against the aggressor.

What Was Old is New Again

The value of distributing lethality is not an unknown or a new idea. In the 1970s, the Soviet Navy was growing and the USN carrier force was dwindling. From the commissioning of the U.S.S. John F. Kennedy in 1968 to the commissioning of the U.S.S. Carl Vinson in 1982, four aircraft carriers were commissioned, while 17 aircraft carriers were decommissioned.5

Faced with this new reality, the USN embraced Corbett’s view of sea control and implemented it in two ways. First, lethality of surface combatants was increased by fielding Harpoon missiles and Tomahawk missiles in both land attack and anti-ship variants. Second, this increased lethality was distributed by retrofitting older classes of ships and equipping future classes of ships with one or both of these weapons. One of the desired effects of this first iteration of Distributed Lethality, was to complicate our adversary’s scouting picture, by making them devote resources to finding, not only our carriers, but our newly lethal surface ships as well.6

Distribution Contributes to Force Survivability

Captain Wayne P. Hughes echoes the issue of complicating an adversary’s scouting picture in the first points on survivability applicable to Distributed Lethality in his book Fleet Tactics: Theory and Practice. “The great constant of scouting seems to be there is never enough of it.”7 This is the effect of “spreading the playing field” admirals Rowden, Gumataotao, and Fanta want to achieve with Distributed Lethality.1

Captain Hughes’ makes and additional point that applies to survivability. That is offensive firepower has the advantage early in a conflict. At Jutland, in the Pacific Theater of Operations, and more recently in the Falklands, offensive weapons were more effective than their defensive counterparts, until defenses had the necessary time to adapt to the realities of those conflicts.8 The USN’s offense will be more effective than our adversary’s defense just at the time when the USN’s surface ships are most likely to encounter the enemy without the support of the larger fleet and its accompanying defensive umbrella. In light of historical examples, how the surface force currently perceives survivability must be challenged.

The Way Forward

The key enabler to Distributed Lethality is developing a training infrastructure rivaling that of Aegis while complementing, not challenging, Aegis . The new training must emphasize the advantages and how to mitigate perceived disadvantages of Distributed Lethality. In order to accomplish this, the training must address exploiting gaps in and deceiving an adversary’s scouting capability, over the horizon targeting, coordinating dispersed offensive capability in an A2/AD environment, and, of course, the proper employment of offensive weapons. Finally, Distributed Lethality training must be delivered at multiple points throughout a Surface Warfare Officer’s career to keep the officer current in the latest tactics, techniques, and procedures, and to build on the officer’s understanding of Distributed Lethality.

The surface force needs to embrace the advantages of a distributed lethal force. The foremost step is equipping our force to be lethal and offensive in posture. However, weapons and sensors are not enough. The surface force must change its mindset. Only through a change of mindset, enabled by time and training, will the surface force be able to fully exploit the strengths of Distributed Lethality.

Call for Articles – July’s Distributed Lethality Week

Week Dates: July 6-10
Articles Due: June 30
Article Length: 500-1500 words
Submit Articles to: nextwar (at) cimsec.org

Since the leaders of the Surface Navy unveiled the concept of
Distributed Lethality in January 2015, the idea has been met with
enthusiastic support.  The basic premise behind Distributed Lethality is that the Surface Navy can increase its combat power by distributing it across more platforms.  By threatening the adversary with more, capable platforms, the Distributed Lethality concept forces the adversary to spread his intelligence, surveillance, and reconnaissance (ISR) assets thin and complicates his targeting problem against U.S. Navy assets.  As Rear Admiral Peter Fanta, Director, Surface Warfare, put it, “if it floats, it fights.”

Distributed Lethality implies a radical shift in the way we train our Sailors, deploy our forces, and equip our ships.  Distributed Lethality will require a fundamental change in the way the U.S. Navy thinks about projecting firepower.  For decades, the centerpiece of U.S. Naval operations has been the Carrier Strike Group.  Some may see Distributed Lethality as the answer to China’s and other’s Anti Access Area Denial (A2AD) strategy, which is apparently designed to keep U.S. Navy aircraft carriers out of the East and South China Seas.  Along the same lines, there are those outside the Surface Navy that suspect Distributed Lethality may be in part a way to wrest control from an often dominant aviation community. Whatever the case is – Distributed Lethality is here and moving forward.

During the first full week of July, CIMSEC will host a series focused on the implementation, opportunities, and challenges of Distributed
Lethality.  Contributions may address programs already in place,
existing technology that could be reoriented toward Distributed
Lethality, new tactics or technologies that might enhance the concept, or some other facet of Distributed Lethality. How can Distributed Lethality defeat the A2AD strategy? What will Distributed Lethality Command and Control look like? How will logistics work? Should Distributed Lethality be employed only by the Surface Navy? Or should it be a Navy-wide concept of operations?

Publication reviews will also be accepted.
