American heavy-lift orbital launch vehicle. 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.

DRM1 American heavy-lift orbital launch vehicle. The Mars Design Reference Mission version 1.0 studied a number of heavy-lift boosters capable of lofting more than 200 metric tons into low earth orbit. The Red Team recommended configuration was an NLS / shuttle-derived vehicle with F-1A powered liquid rocket boosters.
