Angara Launch Vehicle Family series is the next-generation of Russian boosters and is made by Khrunichev's State Research and Production Center. It can be viewed as a response to the Evolved Expendable Launch Vehicle (EELV) families developed in the U.S. The Angara rocket is intended to complement and eventually to replace the Russian existing line of Rockot and Proton boosters. The first launch is planned for 2006 (original launch date 2003). Development is financed by Khrunichev Center and is progressing as scheduled.
Angara Launch Vehicle Design
Angara uses a building-block approach using common components to be able to launch various payload weights. The first stage uses common components called Universal rocket modules (URM-1). The first stage can use either 1 module, 3 modules or 5 modules. The First stage modules are powered by the RD-191 Rocket Engine.
Specs of the First Stage Universal Boosters:
Rocket Engine: RD-191 (thrust about 200 tons)
Propellants: Liquid Oxygen and Kerosene.
Loaded Propellant Mass: 120t
Angara is aimed at drastically lowering the cost of launching a pound of payload to orbit like EELV the series. This flexibility simplifies manufacturing and launch operations. Khrunichev targets operations at a cost to customers of $5,000-6,000 per lb. to geostationary transfer orbits (GTO). The largest version of the Angara will address the anticipated growth of the largest commercial satellites. The Angara launch vehicles will be flown from the Plesetsk Cosmodrome, using ground infrastructure built for Zenit rockets. In the future Angara may also be launched from Baikonur Cosmodrome. Having a modern all-Russian replacement is part of the reason for Angara's development.
The following are the various models in the Angara Launch Vehicle Family:
The Angara 1.1 was presented in Paris in 1999. The light booster would be capable of lifting a 1.6-metric-ton (3,5204b.) payload into low-Earth orbit (LEO), will use RD-191 powered (LOX-Kerosene) first stage, and Hypergolic second stage. It would weigh 148 metric tons at liftoff.
The Angara 1.2, slated to begin service in the first quarter of 2002, will use a Soyuz-3 upper stage (powered by RD-0124), or Khrunichev's own restartable KVRB. It will use LOX-Kerosene fuels for all stages (KVRB is Oxygen-Hydrogen), and would have a LEO capability of 3.5 metric tons (7,700 lb.) and a GTO capability of 1.8 metric tons (3,960 lb.) from an equatorial launch site. One of the options for Angara 1.2 is a winged, reusable first stage. LV fuelled mass will be 170m.t.
Angara AS-I and A4B:
The Angara AS-I and A4B, with a GTO capability from Baikonur Cosmodrome up to 8.8 metric tons (19,3604b.), are due to begin operations in early 2003 and mid-2005, respectively.
Angara-V is top of the line. It will have 3 stages and four liquid-propellant strap-ons, similar to the first stage, that is the same through entire line of LV's. It's LEO capacity will be over 27m.t. (~65,000lb.), and it will be able to put up to 11.2m.t. ( ~ 27,000lb.) into GTO orbit from an Equatorial launch site. The Plesetsk launch site for Angara will be capable to support LEO and GTO launches, and is considered as a future replacement for Baikonur/Proton operations for Russian government and possibly commercial payloads.
Lockheed-Martin is responsible for marketing of Angara internationally.

In the future the first stage modules may be replaced by the 'Baikal' first stage reusable flyback booster. There are plans to turn the RD-191 rocket engine into a reusable engine,
