Russian orbital launch vehicle. The Angara 5A was a proposed variant of the modular launch vehicle that would use four universal rocket modules (URM's) as boosters surrounding one URM in the core, with a Lox/LH2 upper stage. It could put 5.0 tonnes into geosynchronous orbit, or 8.0 tonnes into geosynchronous transfer orbit.

LEO Payload: 28,500 kg (62,800 lb) to a 200 km orbit at 63.00 degrees.

  • Angara The Angara was a new all-Russian heavy launch vehicle designed to replace the Zenit (which was built by a Ukrainian company) and Proton (which had launch pads only on Kazakh territory). The booster was sized for rail transport of modular manufactured components to cosmodromes at Plesetsk and Svobodniy. The design featured a single modular core that could be clustered for large payloads or used as a first stage with a variety of existing upper stages. All plans for the Angara were dependent on financing and subject to constant change. More...
