Submit to: nextwar(at)cimsec(dot)org

In a watershed moment, the Chinese Ministry of National Defense recently published a white paper on the Chinese Military Strategy (with an English-language version made available and published almost immediately by USNI News). This document lays out a policy for future Chinese military engagement with the world, proclaiming the centrality of active defense as the essence of the Chinese Communist Party’s military strategic thought and then describing an approach for implementing this military policy in the air, cyber, land, and maritime domains. This document comes at a particularly interesting time as General Martin Dempsey, Chairman on the Joint Chiefs of Staff, has since approved a new National Military Strategy for the United States, a strategy that names China explicitly as culpable for increased tension in the Asia-Pacific region and establishes an explicit interactive dynamic between the Chinese and U.S. strategies. While this is not the first time a U.S. National Military Strategy names China as a consideration, the shift in tone here is noteworthy.

During the first week of August, CIMSEC will host a series focused on exploring the relationship between the new Chinese military strategy and the strategic policies of the United States and others. Of particular interest are the dynamics of symmetry and asymmetry in their respective National Military Strategies (ideological, technological, doctrinal, coalitional, etc.); the implicit and explicit assumptions in each; the potentially divergent social and political purposes of such documents given their sources; and the implications for the other elements of national power in China, the United States, and the other actors (state and otherwise) in the international system. If the United States and China were to pursue their stated military strategies in whole or in part, what are the implications for their relative and absolute advantage? What are the acknowledged and unacknowledged risks for each in their stated policies?

Contributions should be between 500 and 1500 words in length and submitted no later than 29 July 2015. Publication reviews will also be accepted.

The Role of Swarm Intelligence for Distributed Lethality C2

This article was submitted by guest author Marjorie Greene for CIMSEC’s Distributed Lethality week.  Ms. Greene is a Research Analyst with CNA.  Views expressed are her own.

What will distributed lethality command and control look like?   This article introduces a self-organizing approach that addresses this question.   The increasing vulnerability of centralized command and control systems in network warfare suggests it may be time to take an entirely new approach that builds on the human capacity to interact locally and collectively with one another. Building on the concept of swarm intelligence, the approach suggests that information could be “shared” in a decentralized control system, much as insect colonies share information by constructing paths that represent the evolution of their collective knowledge.

This article builds on a self-organizing system that was developed for military analyses aimed at finding out “who talks to whom, about what, and how effectively” in a wide range of operational situations featuring the involvement of naval forces and commands. In an effort to describe the content of message traffic throughout the chain of command during a crisis, a technique was used to associate messages with each other through their formal references. “Reference-connected sets” were constructed that required no interpretation of the subject matter of the messages and, when further analyzed, were found to uniquely identify events during the crisis. For example, one set that was constructed from crisis-related message traffic found in files at three command headquarters contained 105 messages that dealt with preparation for landing airborne troops. Other sets of messages represented communications related to other events such as providing medical supplies and preparing evacuation lists. The technique therefore provided a “filter” of all messages during the crisis into events that could be analyzed – by computers or humans – without predetermined subject categories. It simply provided a way of quickly locating a message that had the information (as it was expressed in natural language) that was necessary to make a decision [1].

As the leaders of the Surface Navy continue to lay the intellectual groundwork for Distributed Lethality, this may be a good time to re-introduce the concept of creating “paths” to represent the “collective behavior” of decentralized self-organized systems” for control of hunter-killer surface action groups. Technologies could still be developed to centralize the control of multiple SAGs designed to counter adversaries in an A2/AD environment. But swarm intelligence techniques could also be used in which small surface combatants would each act locally on local information, with global control “emerging” from their collective dynamics. Such intelligence has been used in animal cultures to detect and respond to unanticipated environmental changes, including predator presence, resource challenges, and other adverse conditions without a centralized communication and control system. Perhaps a similar approach could be used for decentralized control of Distributed Lethality.

Swarm intelligence builds on behavioral models of animal cultures. For example, the ant routing algorithm tells us that when an ant forages for food, it lays pheromones on a trail from source to destination. When it arrives at its destination, it returns to its source following the same path it came from. If other ants have travelled along the same path, pheromone level is higher. Similarly, if other ants have not travelled along the path, the pheromone level is lower. If every ant tries to choose a trail that has higher pheromone concentration, eventually the pheromones accumulate when multiple ants use the same path and evaporate when no ant passes.

Just as an ant leaves a chemical trace of its movement along a path, an individual surface combatant could send messages to other surface ships that include traces of previous messages by means of “digital pheromones.” One way to do this would be through a simple rule that ensures that all surface ships are kept informed of all previous communications related to the same subject. This is a way to proactively create a reference-connected message set that relates to an event across all surface ships during an offense operation.

In his book, Cybernetics, Norbert Wiener discusses the ant routing algorithm and the concept of self-organizing systems. He does not explicitly define “self-organization” except to suggest it is a process which machines – and, by analogy, humans – learn by adapting to their environment. Now considered to be a fundamental characteristic of complex systems, 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.

The Office of Naval Research has recently demonstrated a new era in autonomy and unmanned systems for naval operations that has great promise for Distributed Lethality. The LOCUST (Low-Cost UAV Swarming Technology) program utilizes information-sharing

between UAVs to enable autonomous collaborative behavior in either defensive or offensive scenarios. In the opinion of this author, this program should be analyzed for its potential application to Distributed Lethality.

Professor Vannevar Bush at MIT was perhaps the first person to come up with a new way of thinking about constructing paths for information-sharing. He suggested that an individual’s personal information storage and selection system could be based on direct connections between documents instead of the usual connections between index terms and documents. These direct connections were to be stored in the form of trails through the literature. Then at any future time the individual himself or one of his friends could retrieve this trail from document to document without the necessity of describing each document with a set of descriptors or tracing it down through a classification tree [2].

The current response to the dilemmas associated with command and control in any distributed operation has led this author to embrace the concept of swarm intelligence. Rather than attempting to interpret the subject matter of information exchanged by entities in confronting an adversary, why not build control systems that simply track information “flows”? Such flows would define the subject matter contained in a naval message without having to classify the information at all.

Any discussion of command and control would be incomplete without including the concept of fuzzy sets, introduced by Professor Lotfi Zadeh at the University of California, Berkeley in 1965. The concept addresses the vagueness that is inherent in most natural language and provides a basis for a qualitative approach to the analysis of command and control in Distributed Lethality. It is currently used in a wide range of domains in which information is incomplete or imprecise and has been extended into many, largely mathematical, constructions and theorems treating inexactness, ambiguity, and uncertainty. This approach to the study of information systems has gained a significant following and now includes major research areas such as pattern recognition, data mining, machine learning algorithms, and visualization, which all build on the theoretical foundations established in information systems theory [3].

Ultimately, the information paths constructed for the control of Distributed Lethality will be a function of organizational relationships and the distribution of information between them. Since a message in a path cannot reference a previous message unless its originator is cognizant of the previous message, the paths in a “reference-connected set” of messages will often reflect the information flows within a Surface Action Group. When paths are joined with other paths, the resulting path often reflects communications across Surface Action Groups. It remains to be determined whether the Surface Navy can use these concepts as it continues to explore the intellectual groundwork for Distributed Lethality. Nevertheless, it is very tempting to speculate that swarm intelligence will play an important role in the future. The most important consideration is that this approach concentrates on the evolution of an event, rather than upon a description of the event. Even if a satisfactory classification scheme could be found for control of hunter-killer Surface Action Groups, the dynamic nature of their operations suggests that predetermined categories would not suffice to describe the complex developments inherent in evolving and potentially changing situations.

Many organizations have supported research and development designed to explore the full benefits of shared information in an environment in which users will be linked through interconnected communications networks. However, in the view of this author, the model of “trails of messages” should be explored again. “Network warfare” will force an increased emphasis on human collaborative networks. Dynamic command and control will be based on communications paths and direct connections between human commanders of distributed surface ships rather than upon technologies that mechanically or electronically select information from a central store. Such an approach would not only prepare for Distributed Lethality, but may improve command and control altogether.

Airborne Over The Horizon Targeting Options to Enable Distributed Lethality

This article was submitted by guest author Michael Glynn for CIMSEC’s Distributed Lethality week. 

The Navy’s surface warfare community is committed to remedying its lack of anti-surface warfare (ASuW) punch with the concept of Distributed Lethality. “If it floats, it fights,” is the rallying cry.[1] Dispersed forces operating together pose challenges for an adversary, but also create targeting difficulties we must solve.

The detection range of shipboard sensors is limited by their height above the waterline and the curvature of the earth. Since it appears doubtful leaders would call on a ship to steam into visual range of adversaries, airborne assets are most likely to provide over the horizon (OTH) targeting.

In a January 2015 article in Proceedings, Vice Admiral Rowden, Rear Admiral Gumataotao, and Rear Admiral Fanta reference “persistent organic” air assets as key enablers of Distributed Lethality.[2] While a completely organic targeting solution offers opportunities in some scenarios, it has limits in high-end contingencies. In empowering the surface force, let us not ignore inorganic air assets. Distributed Lethality is far more effective with them.

TASM: A Cautionary Tale

During a January 2015 test, a Tomahawk Block IV test missile received in-flight updates from an aircraft and impacted its target, a mock cargo ship near the Channel Islands of California.[3] “This is potentially a game changing capability for not a lot of cost,” said Deputy Secretary of defense Bob Work. “It’s a 1000 mile anti-ship cruise missile.”[4]

But this test did not solve the fleet’s ASuW problem. Nor was it the first time the service had used Tomahawk in an anti-shipping role. To understand the difficulty of OTH targeting, we have to examine the final days of the Cold War.

In the late 1980’s, various ships and submarines carried the radar guided Tomahawk Anti-Ship Missile, or TASM. The TASM boasted a range of over 200 nm. But because TASM was subsonic, it took as long as 30 minutes to reach its target. In this time, a fast warship could steam as far as 15 miles from its initial location. Additionally, neutral shipping could inadvertently become the target of the seeker if the enemy vessel was not the closest to the missile when the radar activated.

Therefore, TASM could only reliably be used when there was no neutral shipping around, or in a massive conflict where collateral damage considerations were minimal. The Navy sought to remedy this by developing OTH targeting systems known as Outlaw Hunter and Outlaw Viking on the P-3 and S-3 aircraft. But with the demise of the Soviet Union, massive defense cuts and the evaporation of any blue water surface threat led to the retirement of TASM.

OTH targeting is not a new problem. To solve it, airborne platforms are critical. Let’s examine the organic and inorganic assets that can fill these roles. We will then discuss how inorganic assets offer the most promise.

Organic Assets: Benefits and Limitations

The surface force is equipped with rotary and fixed wing assets to enable OTH targeting. From a sensors standpoint, the MH-60R is most capable. Its inverse synthetic aperture radar (ISAR) can identify ships from long range, but it is limited in altitude and radar horizon. MQ-8 UAV’s offer increased endurance over manned assets. Their maximum altitudes are higher, but still constrain sensor range. The RQ-21 fixed wing UAV rounds out this group. It has solid endurance, but very limited speed.

The limited speed and altitude capabilities of these aircraft mean that the area they can search is small. Also, they must operate well within the weapons engagement zone of their targets to identify their prey. If these sensors platforms are radiating, a capable adversary will hunt them down or lure them into missile traps and destroy them in an effort to deny our forces a clear targeting picture.

Large Fixed Wing Assets: Increased Capability

While not organic to a surface action group, fixed wing aircraft bring speed, altitude, and persistence to the fight. P-8 and P-3 patrol aircraft offer standoff targeting and C5I capabilities. So too do the MQ-4 UAV and the E-8 JSTARS aircraft.

The carrier air wing brings blended detection and OTH targeting capabilities. The E-2 lacks ISAR identification capability, but does boast a passive electronic warfare (EW) suite and the ability to coordinate with the powerful EW system onboard EA-18G aircraft.  Additionally, the latest E-2 model can pass targeting quality data to surface ships to allow them to engage from the aircraft’s track, significantly increasing the ship’s effective missile envelope.

These platforms are expensive and limited in number, but their altitude capability and resulting sensor range allows them to standoff further from the enemy, radiating at will. Additionally, their high dash speed allows them to better escape targeting by enemy fighter aircraft. Their speed, persistence, sensor coverage, and survivability make them logical targeting platforms. They are far more capable and enable better effects than shipboard rotary assets and UAV’s.

Stand-in Stealthy Aircraft: The Ultimate Targeting Asset

The ultimate platform to provide targeting updates to long-range ASCM’s would be a stealthy UAV similar to the RQ-170.[5] Such an aircraft could receive cueing from other platforms, an onboard EW suite, or its own low probability of intercept (LPI) radar.[6] Able to stand in, it could provide visual identification, satisfying rules of engagement. It could provide target updates via a LPI datalink to inbound weapons. These technologies have their roots in the “Assault Breaker” initiative that led to the creation of the Tacit Blue test aircraft and the rise of modern stealth technology.[7],[8] Similar radars, datalinks, and low observable platforms have been proven and are flying today in various forms.[9]

Cost of a new platform is high, but their ability to get close and persist while unobserved is very useful and provides high confidence visual identification to commanders. Their survivability removes the need to provide airborne early warning (AEW) and high value airborne asset protection. Their stealth frees AEW aircraft and fighters to focus their energies elsewhere.

Conclusion

The concept of Distributed Lethality offers promise, but will be limited if its scope is confined to only utilizing capabilities resident in the surface fleet. It is best to pursue organic capabilities while also integrating inorganic assets when planning how the fleet will fight the conflicts of tomorrow. Let us pursue solutions that incorporate forces from many communities to best meet future warfare challenges.

Weaponized Hovercraft for Distributed Lethality

This post was submitted by guest author John Salak for CIMSEC’s Distributed Lethality week. 

Distributed Lethality is a concept that offers the Navy an opportunity to transform our force structure to both enhance and expand mission capabilities to meet our national military objectives. It takes our contemporary carrier-strike group model centered around the striking power of the carrier – and re-distributes that offensive power across an up-armed fleet, and across the battlefield in distributed SAGs. Transforming that concept into reality may call for a little out-of-the-box thinking on how the Navy can achieve a larger footprint that is both scalable to a conflict and adaptable to a variety of missions. Better yet, in an era of significant budget constraints, it would be achieving those capabilities by utilizing existing technologies and assets in platforms, weapons, communications, and sensors in a new combinations that significantly transform tactical employment.

One of those out-of-the-box ideas started out as a way of indirectly enhancing LCS mission capability by utilizing off-board systems to increase the defensive and offensive perimeter with remote weapons platforms. Cooperative Engagement Capability (CEC), a foundation block for distributed lethality, is one of those key technologies for extending the reach of LCS off-board defensive and offensive weapons. Utilizing off-board weapons platforms at a significant distance from the ship effectively buys time in the kill chain for early engagements in a defensive mode, and quicker strike in an offensive mode. As an example, selection of the Vertical Launch capable Hellfire Longbow for LCS opened up the potential to outfit smaller off-board craft with the same weapon and forward deploy those craft to extend the LCS weapons radius. Another foundation block of distributed lethality, the battle space sensor network, eliminates the need for local sensor capabilities on the off-board platform to develop threat and targeting data. CEC provides the communications mechanism to integrate the off-board weapons and fire control with C2 assets to select and engage with the appropriate asset. While the idea was initially applied to enhancing LCS capability, the same concept and capability can be extended to any Navy capital ship with the C2 assets to control an engagement.

The LCS is a pretty fast ship, so off-board weapons platforms have to be not only as fast, but preferably much faster in order to maintain that extended footprint as the LCS force maneuvers. Helicopters (manned or unmanned) are the obvious answer, but they come with their own set of limitations for payload capability, time on-station, and a host of other resource limitations.

So what is the best solution for this high speed, large payload, and high endurance off-board craft? If we look at the Navy’s LCAC hovercraft/air cushion vehicle (ACV), the answer to this providing this new, unique capability becomes apparent. The LCAC is designed to carry payloads up to 70 tons at design speed. Like any ship or aircraft, high speed and high payload usually require significant amounts of propulsion power. In the case of LCAC, what if that power was diverted from payload capacity to increased speed with the end result being a craft capable of near helicopter speeds with 10 times the weapons payload of a helicopter and 4 to 5 times the mission endurance?  We call this modified craft the Fast Air Cushion Expeditionary Craft (FACEC), with a speed capability in the 85-100 knot range and weapon payloads up to 35-45 tons. This high speed craft would use its open cargo deck to provide the capability for utilizing reconfigurable strap-down modular weapons loads, much like an aircraft, matched to specific mission needs.

While the skeptics maybe already firing up their keyboards to mention the problems with Patrol Hydrofoils (PHM) and numerous other past attempts at very high speed naval craft, this is a varied approach. The key difference in this case, and why LCAC has been successful, is the craft was not designed as a ship, it was designed as an aircraft that flies 3m above the water. With all ship based designs, one literally brings along the kitchen sink as part of the weight/speed/power trade, and that has consequences in mission endurance/range, speed, and weapons payloads. With LCAC the kitchen sink, along with everything else not essential to mission performance, gets left behind to the benefit of speed, payload and endurance.  The trade is LCAC requires a host carrier ship for long range transport, crew accommodations, maintenance, fuel, and weapons.

The FACEC conversion of an LCAC would be optimized for high speed by significantly reducing that 70 ton payload capability to a range sufficient for any weapons modules that would fit on the deck. The envisioned weapon payload modules, such as a 24 cell LCS VL-Hellfire, 4 cell Naval Strike Missiles, Harpoon, APKWS, and even MK-41 VLS modules can be combined or swapped out to meet specific mission tasking. Layered weapons capabilities would include remote control guns and self-defense systems. The ability to shoot from the LCAC platform has been demonstrated in the past with efforts such as the GAU-5 based Gun Ship Air Cushion and rocket launched systems such as DET/SABER and the MK-58 lane clearance system.

The utilization of a very high-speed air cushion craft as forward deployed weapons platform/picket in a CEC network provides some interesting engagement scenarios for an opposing force. The speed capability makes rapid deployment and maneuver 50 to 100 miles forward of the main force a practical reality. The off-board weapons capability cannot be ignored in any attempt to engage the main force if the FACEC are deployed in sufficient numbers. The opposing force must either concentrate on taking out small, relatively low value assets or risk being attacked or neutralized by those same assets if they engage the main force directly.

Being an ACV, the FACEC is not restricted by any shallow water maneuvers, which opens up large operating areas that make the A2AD much more difficult for opposing forces. The speed and maneuver capability of FACEC would make it nearly impossible for any surface based vessel like a corvette or fast patrol boat to outrun or hide in an engagement. Being an ACV, the FACEC could hide anywhere there is enough space to park it, including on land, for fire and evade scenarios. In areas of the world where restricted maneuverability is a constraint, FACEC enables the weapons systems to venture into those areas while safely leaving the command ship behind.  Need an AEGIS ashore battery?  Send a FACEC loaded with a pod of SM-x equipped MK-41 VLS on an erectable base and park it anywhere you have a clearing.  Running a mission against a large force of small craft? Send a FACEC with 48 VL Hellfire Longbows and a remote control 25mm gun. Need something to reach and touch the enemy at 100 miles? Send a FACEC with NSMs and/or Harpoons.

FACEC

The astute observer might be wondering about that host ship carrier mentioned earlier. The USMC is already looking for more lift capability and more Lxx type host ships that carry LCAC are not in budget. The additional lift problem is addressed by utilizing a type of commercial off-shore platform support vessel capable of ballasting down to launch and recover the FACEC craft. A 105m craft has been identified that would be an ideal support platform for two embarked FACEC, while providing crew accommodations, maintenance, fueling and most importantly the ability to store and swap out the modular weapon systems. The ballast down capability allows FACEC operations similar to those currently conducted by LCAC and MLP ships. There are also potential alternate missions once the FACEC are launched, such as USMC AAV transport in support of expeditionary operations. In an era of shipbuilding budget pressures, these commercial PSVs are envisioned as another component of the MPS force, and eventual resale as commercial ships once their mission need ends. The FACEC/PSV combination makes a great hunter/killer combination with quick reaction capability.

With the commencement of LCAC-100 production, the U.S. Navy will have eventually have a significant fleet of legacy LCAC available for FACEC conversion. By utilizing existing assets and modifying them for high speed operations, adding CEC comms, along with repackaging some existing weapons to make modular swap outs possible, the Navy has an opportunity to transform force utilization in the littorals. If you want distributed lethality at its best, here is your express pass to get it.
