RLA-135

Russian heavy-lift orbital launch vehicle. Heavyweight booster concept with a payload to low earth orbit of 100 metric tons using two modules as the first stage and the RLA-120 core. Glushko proposed that the booster could launch a Soviet manned lunar landing by 1981. The government rejected the RLA concept, but it did lead to the Zenit-2 and Energia boosters of the 1980's.

LEO Payload: 100,000 kg (220,000 lb) to a 185 km orbit at 52.00 degrees. Development Cost $: 12,500.000 million in 1974 dollars.
