Acquisition Category: ACAT I
Acquisition Lifecycle Phase: Production & Deployment, Operations & Support
The Phased Array Tracking Radar to Intercept of Target (PATRIOT) Missile protects ground forces and critical assets at all echelons from advanced aircraft, cruise missiles, and tactical ballistic missiles (TBM). The PATRIOT Advanced Capability – 3 (PAC-3) is the Army’s premier guided air and missile defense (AMD) system providing highly reactive hit-to-kill capability in both range and altitude while operating in all environments.
The combat element of the PATRIOT system is the fire unit, primarily consisting of a radar set (RS), engagement control station (ECS), and launching stations (LS). The RS provides airspace surveillance, target detection, discrimination, identification, classification, simultaneous tracking of targets, missile guidance, and engagement support. The LS performs transport and missile launch functions and is remotely operated from the ECS, which provides command and control. The LS has a load-out capacity of four legacy PAC-2 interceptors, 16 PAC-3 Cost Reduction Initiative (CRI) interceptors, or 12 PAC-3 Missile Segment Enhancement (MSE) interceptors depending on configuration. The PAC-3 missile, initially fielded in 2001, introduced hit-to-kill technology for greater lethality against TBM, cruise missiles, and aircraft. The combination of a highly responsive airframe and attitude control motors generates an angle-of-attack that would not be achievable with actuator-driven aerodynamic control surfaces alone.
The PAC-3 MSE, fielded in 2015 provides expanded battlespace performance against evolving threats. The PAC-3 MSE improves upon the original PAC-3 capability with a higher performance dual-pulse solid rocket motor, modified lethality enhancer, more responsive control surfaces, upgraded guidance software, and insensitive munitions improvements.
PAC-3 milestone authority was assigned to the Army in 2004. The Army Acquisition Executive is the Milestone Decision Authority for the PAC-3 and PAC-3 MSE programs. The Army continues to modernize PATRIOT through phased efforts to maintain and improve system capabilities in the complex threat environment. This modernization provides greater resilience against advanced threats and leverages the enlarged engagement area afforded by the PAC-3 MSE interceptor. PATRIOT is transitioning to the Integrated Air and Missile Defense Battle Command System networked architecture.
