USB

Part of Mir-2

DOS Laser

Russian military anti-satellite system. Study 1978. As platforms for operational versions of space-borne weapons NPO Energia designed a Universal Service Block, based on the DOS-7K space station, in the late 1970's/early 1980's.

Status: Study 1978. Gross mass: 20,000 kg (44,000 lb).

The USB was equipped with common service systems and rocket engines. In comparison to the DOS the USB had much larger propellant tanks to allow substantial orbital maneuvering. The USB would be equipped with either a laser payload or a weapons bay consisting of ten miniature rocket homing vehicles.

The Proton launch vehicle would be used to launch a 20 metric ton version of the USB for experimental flight tests. Operational 30 metric ton vehicles would be delivered to orbit by the Buran space shuttle. Buran would also bring crews for on-orbit servicing of the USB. For this purpose the USB had a life support capability of two crew for seven days.

The mass of the military payload depended on the amount of propellant loaded. The laser payload was heavy with a resulting lower fuel fraction and was limited to use against low earth orbit targets. The UBM with the rocket homing vehicles had more propellant and could be used for attack of geostationary orbit targets.

Family: anti-satellite. Country: Russia. Launch Vehicles: Proton, Energia. Agency: Korolev bureau, MO.
