MLLV
American SSTO VTOVL orbital launch vehicle. Boeing study, 1969, for Saturn follow-on. Plug nozzle, single-stage-to-orbit launch vehicle could itself put 1 million pounds payload into orbit. By addition of up to 12 260 inch solid motors up to 3.5 million pounds payload into orbit with a single launch.

Status: Study 1969. Thrust: 313,624.20 kN (70,505,525 lbf). Gross mass: 25,132,660 kg (55,408,030 lb). Height: 94.00 m (308.00 ft). Diameter: 21.86 m (71.71 ft).

Flyaway Unit Cost 1985$: 1,339.800 million.

Stage Data - MLLV
