Protects ground forces and critical assets at all echelons from advanced aircraft, cruise missiles, and tactical ballistic missiles.


The PAC-3 MSE program is an air-defense, guided missile system with long-range, medium- to high-altitude, all-weather capabilities designed to kill Tactical Ballistic Missiles (TBMs), cruise missiles, and advanced aircraft. The combat element of the PATRIOT missile system is the fire unit, which consists of a phased array Radar Set (RS), an Engagement Control Station (ECS), a battery command post, an electric power plant, an antenna mast group, a communications relay group, and Launching Stations (LS) with missiles.

The RS provides the tactical functions of airspace surveillance, target detection, identification, classification, tracking, missile guidance, and engagement support. The ECS provides command and control. The LS provides the platform for the PAC-3 MSE missile, which is sealed in canisters that serve as shipping containers and launch tubes.

The PAC-3 MSE missile uses hit-to-kill technology for greater lethality against TBMs armed with weapons of mass destruction. The PAC-3 MSE represents the next generation PAC-3 missile providing expanded battlespace performance against evolving threats. The PAC-3 MSE improves upon current PAC-3 Cost Reduction Initiative (CRI) missile capability with a higher performance solid rocket motor, modified lethality enhancer, more responsive control surfaces, upgraded guidance software, and insensitive munitions improvements.
The PAC-3 MSE incorporates a logistical flexibility over that of PAC-3 CRI through a modular single canister. The PAC-3 MSE single canisters will be kitted as a two-pack for both the shipping and tactical configuration. Additionally, the PAC-3 MSE single-pack canister design modularity enables field replacement of spent/failed missile(s). There will be no anticipated increase in PATRIOT operations or maintenance personnel as a result of integrating the PAC-3 MSE enhancements into PATRIOT.

PATRIOT’s fast-reaction capability, high firepower, ability to track numerous targets simultaneously, joint interoperability, and ability to operate in a severe electronic countermeasure environment make it the Army’s premier air defense system.
