IHLLV
Part of Shuttle Family
American orbital launch vehicle. Same concept as Shuttle C. Shuttle orbiter replaced by recoverable pod with shuttle main engines and payload canister. Quick way for US to obtain heavy payload capability and reduce shuttle cost per kg to orbit by 3 X.

AKA: Interim Heavy Lift Launch Vehicle. Status: Study 1980. Payload: 77,000 kg (169,000 lb). Thrust: 20,299.20 kN (4,563,442 lbf). Gross mass: 1,966,675 kg (4,335,776 lb). Height: 56.00 m (183.00 ft). Diameter: 8.70 m (28.50 ft). Apogee: 400 km (240 mi).

LEO Payload: 77,000 kg (169,000 lb) to a 400 km orbit at 28.00 degrees. Flyaway Unit Cost 1985$: 84.970 million.
