The AN/MPQ-64 Sentinel provides persistent air surveillance and fire control quality data through command and control systems to defeat Unmanned Aerial Systems (UAS), cruise missiles and fixed- and rotary-wing aircraft threats.
The system features an X-Band, 360-degree phased array air defense radar with a 75-km instrumented range. It is equipped with Electronic Counter-Counter-Measure capabilities, a Mode 5 Identification Friend or Foe subsystem for positive identification of friendly aircraft, and Non-Cooperative Target Recognition capabilities to identify threat aircraft. Sentinel is trailer-mounted, pulled by either a High Mobility Multipurpose Wheeled Vehicle or an M1082 Family of Medium Tactical Vehicles truck. The system generator with a command and control interface is mounted on the vehicle.
Sentinel interfaces with the Integrated Air and Missile Defense (IAMD) Battle Command System architecture, the Forward Area Air Defense Command and Control System, and the National Capital Region Integrated Air Defense Command and Control System. Sentinel also interfaces with the Counter-Rocket, Artillery, Mortar (C-RAM) Increment I system to protect friendly aircraft during engagement of incoming indirect fire.
Sentinel is undergoing modifications to further enhance its detection, classification, identification and reporting capability against UAS, RAM and cruise missiles. Additional hardware modifications will include the upgrade of the Signal Data Processor and transition to Active Electronically Scanned Array technology.
