REDSTONE ARSENAL, Ala. – Ground-to-air missile experts at Lockheed Martin Corp. will upgrade and support the U.S. Army Phased Array Tracking Radar to Intercept on Target Advanced Capability-3 (Patriot PAC-3) missile under terms of a $6.1 billion contract announced last week.

Officials of the U.S. Army Contracting Command at Redstone Arsenal, Ala., are asking the Lockheed Martin Missiles and Fire Control segment in Grand Prairie, Texas, for incidental services, hardware, facilities, equipment, manufacturing and testing efforts to produce PAC-3, missile segment enhancement configuration, ground-support equipment, and spare parts.

Patriot PAC-3 is a hit-to-kill missile designed to defeat tactical ballistic missiles, cruise missiles, and aircraft. It is a high- to medium-altitude long-range air defense missile that defends ground combat forces and high-value military equipment.

The PAC-3 missile is a high velocity interceptor that defeats incoming targets by body-to-body direct impact. PAC-3 missiles, when deployed in a Patriot battery, provide 16 PAC-3s on a Patriot launcher.

Lockheed Martin also handles the PAC-3 missile segment upgrade, which consists of the PAC-3 missile, PAC-3 missile canisters in four packs, a fire solution computer, and an Enhanced Launcher Electronics System.

The PAC-3 missile uses a solid propellant rocket motor, aerodynamic controls, attitude control motors, and inertial guidance to navigate.

The missile flies to an intercept point specified prior to launch by its ground-based fire solution computer, which is embedded in the system's engagement control station. The PAC-3 system can update target trajectory data during missile flyout with a radio frequency uplink and downlink.

Shortly before arrival at the intercept point, the PAC-3 missile’s on board Ka-band radar seeker acquires the target, selects the optimal aim point, and guides the missile to its target.

The PAC-3's attitude control consists of small short-duration solid- propellant rocket motors in the missile forebody, and fire to refine the missile’s course to ensure the missile hits its target.

The PAC-3 MSE missile is the primary U.S. interceptor for the multinational MEADS transatlantic development program focused on the next generation of air and missile defense.

On this order Lockheed Martin will do the work in Huntsville, Ala.; Camden, Ark.; Ocala, Fla.; Chelmsford, Mass.; Grand Prairie and Lufkin, Texas; and Archbald, Pa., and should be finished by June.
