RLA150

Russian heavylift orbital launch vehicle. Superbooster concept with a payload to low earth orbit of 250 metric tons using six modules as the first stage and the RLA120 core. Glushko proposed that the booster could launch a Soviet manned Mars landing by 1983. The government rejected the RLA concept, but it did lead to the Energia booster of the 1980's.
LEO Payload: 250,000 kg (550,000 lb) to a 185 km orbit at 52.00 degrees. Development Cost $: 12,500.000 million in 1974 dollars.

RLA The RLA (Rocket Flight Apparatus) family of modular, lox/kerosene powered vehicles were designed by Glushko in 1974 to meet the Soviet military's thirdgeneration space launch requirements. The approach was rejected by 1976 in favor of the Zenit/Energia family using both lox/kerosene amd lox/hydrogen stages. More...
