Description
Description — Sentinel Mods
FY26 funds in the amount of $462.010M support the procurement of the Army Modernization Priorities in support of the Sentinel Radar programs and will provide for an incrementally fielded Integrated Air and Missile Defense Fire Control System/capability for the composite Army Air and Missile Defense Brigades. The Sentinel systems are a key component of the Army Integrated Air and Missile Defense (AIAMD) architecture, providing critical air surveillance of the forward areas. The Sentinel A4 utilizes Active Electronically Scanned Array (AESA) technology that is a ground-based sensor system designed to locate, identify and track Cruise Missiles, Fixed-Wing and Rotary-Wing Aircraft, Unmanned Aircraft Systems and Rocket, Artillery, and Mortar (RAM) projectiles. The simultaneous multi-mission Sentinel A4 system will provide 360-degree surveillance and tracking with the ability to handle simultaneous threats arriving from different azimuths. The Sentinel A3 consists of a trailer mounted radar with its prime mover, generator, identification Friend or Foe (IFF) system and Forward Area Air Defense Command, Control and Intelligence (FAAD C2I) systems interface. The Sentinel A3 provides persistent surveillance and fire control quality data on Army and Joint networks through external C2 platforms enabling protection of U.S. and coalition forces as well as critical geo-political assets against Cruise Missiles (CM), Fixed-Wing, Rotary-Wing Aircraft and Unmanned Aircraft System (UAS) threats.
