Test Facility Capabilities

Large, Ambient Engine Test Facility (2 Positions, B‐1a and B‐1b)

The B Test Complex consists of a dual-position; vertical, static-firing test stand designated as the B-1/B-2 test stand. Each test position is capable of static-firing test articles up to 33 feet diameter. The B-1/B-2 Test Stand is equipped with a 195-ton, main derrick lifting crane, with a 20-ton jib crane. The B-1 test position was configured for the first stage of the Saturn V rocket but was never utilized.  In the late 1980s, the B-1 position was modified for single engine testing for the Space Shuttle Main Engine  program. In the late 1990s, the B-1 position was modified to test the Aerojet Rocketdyne RS-68 engine, which concluded in 2023.
