Test Facility Capabilities

Large, Ambient Engine Test Facility

Originally known as the A-1 Test Stand, the renamed Fred Haise Test Stand was designed to test fire the Apollo Saturn V second stage (S-II) – a cluster of five J-2 rocket engines capable of developing a 1.15-million-pound thrust at altitude. The Fred Haise Test Stand was converted to a single-position, vertical-firing test stand used to test liquid rocket engines at sea level conditions. It is currently configured for engine testing, with a 33-foot diameter opening within the thrust drum.

Maximum Thrust: 1,500,000 pounds (original design); 650,000 pounds (current configuration)
Altitude: Ambient
Propellants: Liquid oxygen, liquid hydrogen
