Large Class Stage 2 (LC2)

Large Class Stage 2 (LC2) is under development as a demonstration of enabling technologies to support strategic deterrence, conventional strike and rapid space response. It is derived from the Peacekeeper Stage 2 SR-119 motor requirements but includes a longer case, domestic composite case materials, and an electro-mechanical TVA system. The motor diameter is ~92-in. diameter and can be used for other vehicle applications such as an upper stage for space launch and/or target launch vehicles.

Motor development is being conducted under the Air Force’s Propulsion Applications Program for Large Class Technology Demonstration with static testing planned in 2013.
