The Rocketdyne XRS-2200 was an experimental linear aerospike engine developed in the mid-1990s for the Lockheed Martin X-33 program.[1][2][3] The design was based on the J-2S, the upgraded version of the Apollo era J-2 engine developed in the 1960s. The XRS-2200 used the J-2's combustion cycle and propellant choice.[4]
Rocketdyne intended to develop the subscale XRS-2200 into the RS-2200 for use on the VentureStar. While the X-33 program was cancelled, two XRS-2200 engines were produced and tested.[5]
