Burlak
Russian air-launched winged orbital launch vehicle. Burlak air-launched satellite launcher was proposed in 1992 and studied by Germany in 1992-1994. Evidently based on secret anti-satellite missile. Air launched from Tu-160 bomber, released at 13,500 m altitude and Mach 1.7. Development estimated to cost only DM 50 million, but not proceeded with. Burlak/Diana variant would have been launched from Concorde.

Status: Cancelled 1992. Payload: 1,100 kg (2,400 lb). Thrust: 302.00 kN (67,892 lbf). Gross mass: 27,400 kg (60,400 lb). Height: 19.00 m (62.00 ft). Diameter: 1.60 m (5.20 ft). Apogee: 200 km (120 mi).

LEO Payload: 1,100 kg (2,400 lb) to a 200 km orbit. Payload: 550 kg (1,210 lb) to a 1000 km polar orbit. Launch Price $: 5.000 million in 1994 dollars.
