MPTA-098
The Main Propulsion Test Article (MPTA-098) was built by Rockwell International as a testbed for the definitive propulsion and fuel delivery systems for the U.S. Space Shuttle Program. ==Description== Never intended for actual spaceflight, the MPTA consisted of the internal structure of a Space Shuttle orbiter aft-fuselage, a truss structure that simulated the basic structure and shape of an orbiter mid-fuselage and a complete Space Shuttle Main Engine (SSME) assembly, including all main propulsion system plumbing and the associated electrical systems. Later, the very different STA (Structural Test Article) was converted into a flightworthy orbiter, re-designated OV-099, and christened ''Challenger''. Rockwell and NASA thus retroactively re-designated the MPTA as MPTA-098, though it was never christened with a name.
