How America's M1 Abrams Tanks Will Defeat One of Its Greatest Foes

Army Abrams tanks, Bradleys and Strykers are being outfitted with high-tech, vehicle-mounted systems which can detect, track and destroy approaching enemy RPG fire within milliseconds.

The Army is fast-tracking an emerging technology for Abrams tanks designed to give combat vehicles an opportunity identify, track and destroy approaching enemy rocket-propelled grenades in a matter of milliseconds, service officials said.

Called Active Protection Systems, or APS, the technology uses sensors and radar, computer processing, fire control technology and interceptors to find, target and knock down or intercept incoming enemy fire such as RPGs and Anti-Tank Guided Missiles, or ATGMs. Systems of this kind have been in development for many years, however the rapid technological progress of enemy tank rounds, missiles and RPGs is leading the Army to more rapidly test and develop APS for its fleet of Abrams tanks. 

“The Army is looking at a range of domestically produced and allied international solutions from companies participating in the Army's Modular Active Protection Systems (MAPS) program,” an Army official told Scout Warrior.

The idea is to arm armored combat vehicles and tactical wheeled vehicles with additional protective technology to secure platforms and soldiers from enemy fire; vehicles slated for use of APS systems are infantry fighting vehicles such as Bradleys along with Stykers, Abrams tanks and even tactical vehicles such as transport trucks and the emerging Humvee replacement, the Joint Light Tactical Vehicle.

“The Army's expedited APS effort is being managed by a coordinated team of Tank Automotive Research, Development & Engineering Center engineers, acquisition professionals, and industry; and is intended to assess current APS state-of-the art by installing and characterizing some existing non-developmental APS systems on Army combat vehicles,” the Army official said.

General Dynamics Land Systems, maker of Abrams tanks, is working with the Army to better integrate APS into the subsystems of the Abrams tank, as opposed to merely using an applique system, Mike Peck, Business Development Manager, General Dynamics Land Systems, told Scout Warrior in an interview. 

Peck said General Dynamics plans to test an APS system called Trophy on the Abrams tank next year. 

Being engineered as among the most survivable and heavily armored vehicles in existence, the Abrams tank is built to withstand a high degree of enemy fire, such some enemy tank rounds, RPGs, rockets and missiles. Abrams tanks can also carry reactive armor, material used to explode incoming enemy fire in a matter that protects the chassis and crew of the vehicle itself. However, depending upon the range, speed and impact location of enemy fire, there are some weapons which still pose a substantial threat to Abrams tanks. Therefore, having an APS system which could knock out enemy rounds before they hit the tank, without question, adds an additional layer of protection for the tank and crew. A particular threat area for Abrams tanks is the need the possibility of having enemy rounds hit its ammunition compartment, thereby causing a damaging secondary explosion. 

APS on Abrams tanks, quite naturally, is the kind of protective technology which could help US Army tanks in tank-on-tank mechanized warfare against near-peer adversary tanks, such as a high-tech Russian T-14 Armata tank. According to a report in The National Interest from Dave Majumdar (Click Here for Story), Russian T-14s are engineered with an unmanned turret, reactive armor and Active Protection Systems.  

A challenge with the technology is to develop the proper protocol or tactics, techniques and procedures such that soldiers walking in proximity to a vehicle are not vulnerable to shrapnel, debris or fragments from the explosion between an interceptor and approaching enemy fire.

“The expedited activity will inform future decisions and trade-space for the Army's overarching APS strategy which uses the MAPS program to develop a modular capability that can be integrated on any platform,” the Army official said.

Trophy: 

DRS Technologies and Israeli-based Rafael Advanced Defense Systems are asking the U.S. Army to consider acquiring their recently combat-tested Trophy Active Protection System, a vehicle-mounted technology engineered to instantly locate and destroy incoming enemy fire.

 Using a 360-degree radar, processor and on-board computer, Trophy is designed to locate, track and destroy approaching fire coming from a range of weapons such as Anti-Tank-Guided-Missiles, or ATGMs, or Rocket Propelled Grenades, or RPGs,

The interceptor consists of a series of small, shaped charges attached to a gimbal on top of the vehicle. The small explosives are sent to a precise point in space to intercept and destroy the approaching round, he added.

Radar scans the entire perimeter of the platform out to a known range. When a threat penetrates that range, the system then detects and classifies that threat and tells the on-board computer which determines the optical kill point in space, a DRS official said.
