Launch vehicle originally designed in the 1980's to fulfill the third generation 20-30 metric tons to orbit launcher requirement. It was an adaptation of the Energia launch vehicle, using two strap-on booster units instead of four, and a reduced-diameter core using a single RD-0120 engine instead of four. In the 1990's a structural test article was built and it was proposed that several Energia-M's be launched for commercial customers using surplus Energia components. No buyers came forward for the untested design.

Status: Development ended 1993. Payload: 34,000 kg (74,000 lb). Thrust: 16,015.80 kN (3,600,495 lbf). Gross mass: 1,022,800 kg (2,254,800 lb). Height: 24.00 m (78.00 ft). Diameter: 7.70 m (25.20 ft). Apogee: 200 km (120 mi).

It was later proposed as an alternate for the Angara launch vehicle, but it was not accepted for that role since Angara was to be an all-Russian design (the Energia boosters were built in Ukraine).

LEO Payload: 34,000 kg (74,000 lb) to a 200 km orbit. Flyaway Unit Cost 1985$: 80.000 million.
