The Future of Military Unmanned Vehicle Technology

The US Army’s Futures Command is the most important administrative reorganization of the modern Army. Responding to the world’s changing priorities— especially the “near peer” threat of ascendant Russia and China—the Army is no longer modernizing, but re-inventing its ground vehicle fleet against new realities. Just like the U.S. Air Force stopped inventing better jets and pilot aids and moved to unmanned aerial vehicles (UAV) for “dull, dirty and dangerous” missions, the Army envisions multiple autonomous vehicle concepts. Instead of a heavier Abrams main battle tank, or a replacement to the aging M113 APC, autonomous “wingman” vehicles may replace some of the human-heavy tasks on the future battlefield.

The questions are many: What is to be the deployment doctrine and the sensors capabilities? Are these new vehicles armed or merely for C4ISR? And indeed, are they actually “autonomous” or controlled, like USAF UAVs, by remote operators from mobile ground stations? The good news is, regardless of how the doctrine or vehicle takes shape, the Army’s own MVD (Multi-function Video Display) system can be “appliqued” from the Type II MRAP Mine Clearing Vehicle and used to remotely control all aspects of tomorrow’s “wingman” autonomous vehicles.

In this article, we briefly examine what the Army’s Futures Command has published on future vehicle fleet, autonomy, and the evolving use cases. The article examines the type of sensors, control and telemetry needed between an autonomous vehicle and its “chase Mobile Ground Station,” and describes the capabilities of the MVD on MRAP vehicles and how it directly applies to the battlefield of the future. Brief references to Next Generation Combat Vehicles will be made, although at time of writing, this program is still evolving and far from settled.

National Defense Strategy Stays Ahead of Russia and China

By 2025, the Army sees ground troops conducting foot patrols in urban terrain with robots, called Squad Multipurpose Equipment Transport vehicles, that carry rucksacks and other equipment alongside soldiers. Overhead, unmanned aircraft will also serve as spotters to warn troops so they can engage the enemy on their own terms, according to the the Army's new strategy on robotic and autonomous systems.

In less than 20 years, the US has changed its defense doctrine multiple times in response to world events like 9/11, urban warfare in Iraq, fighting ISIS—and now, a realization that Russia and China are legitimate battlefield foes. While the first part of the Department of Defense’s mission statement says America still intends to effectively fight in two battle theaters simultaneously (a carry-over from World War II), the second half of the mission statement guaranteeing to “prevail using overwhelming force” has DoD planners worried.

In early 2018, the Pentagon’s National Defense Strategy (NDS) recognized that on land, sea and in the air, the reality is that both Russia and China pose serious threats. Military planners believe there is no longer 100 percent confidence in America’s technical and weapons superiority. In Syria, DoD planners watched Russia “test bed” new offensive and defensive strategies and technology—and concluded that America needed to re-evaluate many of our deployed platforms.

The Army brass knew something had to change. While weapons like the M1A2 Abrams main battle tank were designed for head-to-head European combat against Russian tanks, the reality shown in Crimea is that Russian EW and cyber capabilities will affect Army infrastructure sooner than Russian armored vehicles. Apparently with little effort, Russia was able to “see” and “kill” the opposing forces’ command and control structure. Currently using a fixed and slow-to-erect Forward Operating Base (FOB) concept dating to World War I/II, the Army has realized that speed—coupled with a “shoot and scoot” model—is now essential for modern warfare.

New Army Cross Functional Teams (CFTs) and NGCV

In late 2017, Army Chief of Staff Mark Milley outlined a set of eight cross-functional teams (CFTs) designed to address new battlefield realities, and more importantly, to bring essential capabilities right to the warfighter as quickly as possible. The CFTs are listed in Figure 1.

Figure 1. The U.S. Army’s Cross Functional Teams (CFTs). Note that the Next Generation Combat Vehicle isn’t a single vehicle, but a set of at least five different platform types.

The CFTs bring together multiple Army organizations, labs, vendors and industry to openly discuss out-of-the-box ways to address the (primarily) Russian threat. From a ground vehicle perspective, platforms will have increased lethality and mobility, effectively inter-communicate in a denied network and GPS environment, and bring back the “overwhelming force” part of the DoD’s mission statement. In the past, bigger was better. In the near future— by 2025, in fact—smaller, more nimble, networked, and autonomous vehicles will enter the ground vehicle fleet. Sensors will be an essential enabler to realize an autonomous vehicle fleet.

At the Future Ground Combat Vehicles Summit near TACOM in Detroit, Michigan, in December, Col. Warren Sponsler, Deputy Director, NGCV CFT, Army Futures Command, contrasted the difference between today’s one-on-one/ vehicle-to-vehicle approach versus the future multi-domain approach (Figure 2, upper left frame).

In the lower frame, each ground vehicle is networked to all other joint battlefield assets. This is essentially no different from today’s digital battlefield concept— except it’s still not a reality. Joint assets are rarely directly inter-connected due to interoperability constraints, relying instead on intermediaries like FOBs, AWACS, E2C, and other human latency-prone “switch” points. In the upper right frame, however, the NGCV CFT envisions new platforms supplementing ground vehicles by providing reconnaissance and offensive strike. Shown here, autonomous drone swarms complement the indicated autonomous vehicles. Both are inter-linked to human-operated ground vehicles and dismounted soldiers.

Enter NGCV: Not One, but Five

While NGCV is one of the Army’s top eight CFTs, NGCV itself is not a single vehicle but instead a set of CFTs that are creating over five different new ground vehicle concepts that all rely on sensors like cameras, LIDAR, multiple battlefield networks, and massive on-board processing and digital storage. Designed to supplement or replace some current weapons platforms like the M113 and Bradley Fighting Vehicle (BFV or M2), the concept of Manned Unmanned Teaming (MUM-T) currently used on the Army’s Apache helicopter will become a ground reality as long as the technology enables the platform.

Each of the five NGCV CFT concepts includes some form of autonomy. The Robotic Combat Vehicles (RCV) shown in Figure 3 are light, medium and heavy RCVs designed to act as a “wingman” to other ground vehicles. Used ahead of a strike force, the RCVs might enable reconnaissance, offensive weaponry, mobile FOB/command post capability, and even “feint” operations to draw an enemy away from the main Army fighting force.
