STME Rocketdyne lox/lh2 rocket engine. 2890 kN. Cancelled 1984. Isp=430s. Space Transportation Main Engine. Rocketdyne was teamed with Aerojet and Pratt & Whitney on the STME, which was to have powered the next generation of large launch vehicles. More...
NLS New (or National) Launch System (NLS) joint NASA/USAF studies began in 1989, following the demise of the ALS. They proposed development of a family of launch vehicles using a new STME engine to replace the existing ‘high cost' boosters derived from 1950's missile designs. The $12 billion nonrecurring cost was nearly that estimated for ALS, and this cost could not be recouped at projected launch rates. NLS was terminated in 1991. More...
