RS-2200
From Wikipedia, the free encyclopedia
The Rocketdyne RS-2200 was an experimental linear aerospike rocket engine developed by Rocketdyne for Lockheed Martin's VentureStar program.[1][2] The program was ultimately cancelled in 2001 before any RS-2200 engines were assembled. [3][4][5]

XRS-2200
The XRS-2200 was a subscale testbed engine intended to be developed into the full-scale RS-2200. Unlike its full-scale counterpart, this engine made it to the test stand and accumulated approximately 1,600 seconds of hot-fire testing. [3]
