The US Seeks Universal Modular APS for Armored Vehicles

The US Army has issued a Request for Information (RFI) for a Multi-Mode Armament System-Active Protection System (MMAS-APS).

According to a publication on, the US Army Contracting Command (ACC), in support of the Combat Capabilities Development Command (CCDC) Armaments Center, is conducting a market survey to understand industry capability to provide a vehicle-based tracking and fire control sensor capable of providing fire-control quality data to a hard-kill countermeasure (HKCM) system. This will enable the defeat of threats at a standoff distance that reduces or mitigates collateral damage risk to dismounted soldiers. This requires tracking of small projectiles, RPGs, anti-tank guided missile (ATGM), Kinetic Energy (KE) weapons, small Unmanned Aircraft System (UAS) and/or Sensor-fused Munitions, etc.

The tactical fire control sensor (including but not limited to radar, Electro-Optical/Infra-Red (EO/IR), active/passive) would be vehicle mounted (configurable to be mounted onto Army Ground Combat vehicles including High Mobility Multipurpose Wheeled Vehicle (HMMWV), Bradley, Stryker, Abrams, Joint Light Tactical Vehicle (JLTV), and next-generation combat vehicles). It must be small, lightweight, affordable, and would be suitable for stationary and on-the-move operations.

As a result of issuing this Request for Information (RFI), the Government is requesting to receive white papers describing proposed concepts and technologies. The RFI responses should identify sensor designs that will support the Armaments Center system concept and include a credible development path, with estimates provided on costs and timeline. The subject matter may be considered a "critical technology" and therefore, subject to ITAR restrictions.

The system must detect and track target classes to include small-Radar cross-section (RCS) classes of targets, Rockets, Artillery, and Mortars (RAM), Rocket propelled grenade (RPG), Anti-Tank Guided Missiles (ATGM), and kinetic energy weapons. Sensor coverage should be hemispherical (360-degree azimuth coverage, 0-90 degree elevation coverage).

The system must be able to operate with real-time search-quality cues from external sources to the vehicle. Vendors should define or parameterize the external surveillance cue basket required to enable rapid/efficient track acquisition. The system must communicate target data to an external system in real-time and possess the ability to become Modular Active Protection System (MAPS) and Modular APS Framework (MAF) compliant.

At this point, it is unclear which Israeli companies are participating in the RFI, however it is safe to assume that both Rafael and Elbit Systems are natural contenders for this kind of technology.
