SSC maintains a number of facilities and provides specialized services required for the direct support and operation of test facilities. Included are a cryogenics propellant receiving area, a High Pressure Gas Facility (HPGF) and a High Pressure Industrial Water (HPIW) facility.

Cryogenics Operations provide LOX and LH2 for the engine testing programs at SSC that require liquid propellants. This support includes operating and maintaining an LH2 Storage and Transfer Facility, a LOX Transfer Facility, three LH2 , and six LOX barges.

The HPIW facility furnishes water to the "A" and "B" Test Complexes for test stand deflector coolant, fire protection (deluge), and diffuser operation (A-2 and B-1). It also furnishes water for fire protection of the propellant barges (LH2) at the test stands.

The HPGF receives, stores, and distributes the HP gases required to support engine testing programs and other SSC-assigned missions. The HPGF supplies air, GHe, GN2, and GH2.
