Description: The Angara is a family of space launch vehicles being built on the basis of a Common Core Booster (CCB) or Common Rocket Module (CRM) using the RD-191 reusable liquid fuel engine. The program was launched in 1995 and its main purpose is to ensure space access for the Russian Ministry of Defense for several decades from Plesetsk launch site. The Angara family comprises small-, medium- and heavy-lift space vehicles which can be launched from the same pad in Plesetsk. Its key component of the CCB/CRM is the environment-friendly liquid oxygen (LOX) kerosene RD-191 engine. The Angara family can put payloads into low-Earth orbit weighing from 2,000 to 24,500 kg, or up to 4,500 kg into geosynchronous orbit. The first Angara space launch system is expected to lift-off after 2010.
The Angara A3 is a two-stage, medium-lift space launch vehicle comprising three Common Core Boosters (CCBs) at the first stage, including two Baikal reusable boosters; one 62,000-lb RD-0124 motor at the second stage; and the Breeze M upper stage. With a maximum lift-off weight of 480-ton the Angara A3 can put into low-Earth Orbits payloads of up to 14,000 kg. Besides, the Breeze M can lift payloads of up to 3,700 kg (or 2,400 kg) to a geo-transfer orbit at 5,500 km of altitude and 25-degree of inclination or place directly payloads of up to 2,000 kg (or 1,000 kg) into geostationary orbit. The Breeze M upper stage has a diameter of 4.35 meters and 11.6 or 15.25 meters in length.
