Theater High Altitude Area Defense (THAAD)
The Theater High Altitude Area Defense (THAAD) missile uses a single-stage, solid propellant rocket motor with thrust vector actuation (TVA). The booster stage is manufactured by Pratt & Whitney (P&W) Space Propulsion, located in San Jose, Calif. The critical booster TVA system is co-designed and manufactured by P&W and HSC Missiles, Space, and Undersea Systems. The THAAD Demonstration/Validation Program (now known as Program Definition and Risk Reduction) was initiated in Sept. 1992 and flight boosters were delivered to the prime contractor, Lockheed Martin, Sunnyvale, Calif., to support the first flight test on April 21, 1995. The flight test program concluded with two successful, consecutive hitto-kill ballistic missile intercepts on June 10, 1999 and Aug. 2, 1999. The program has now transitioned into the Development phase. The motor case is a high length/small diameter, graphite epoxy, high-strength design utilizing a full open aft end. This allows incorporation of a movable nozzle assembly and ease of propellant processing. The case was designed, developed, and produced at P&W. The propellant is an aluminized formulation that satisfies both ballistic and total impulse requirements while operating successfully in extreme environments. The booster has successfully passed high (>+45ºC) and low (<-40ºC) temperature cycling and subsequent static test. P&W is proud of its role in supporting the THAAD program for the US Army Missile Defense Agency, THAAD Project Office and Lockheed Martin.
