Orbital launch vehicle. Year: 1987. Family: Delta. Country: USA. Status: Study 1987. Proposed launch vehicle for large SDI 'Star Wars' payloads. Expected to cost $ 400-500 million, the Barbarian could place the Zenith-Star chemical laser into low earth orbit. It would consist of 3 Shuttle SRM's, attached around a ring of six Delta RS-27 first stage boosters, which in turn clustered around a single Delta first stage booster that was the last stage of the launch vehicle. Manufacturer: Douglas. LEO Payload: 45,400 kg (100,000 lb). to: 300 km Orbit. at: 28.00 degrees. Liftoff Thrust: 35,789.560 kN (8,045,813 lbf). Total Mass: 2,500,000 kg (5,500,000 lb). Core Diameter: 2.44 m (8.00 ft). Total Length: 31.00 m (101.00 ft). Launch Price $: 500.000 million. in: 1987 price dollars.
