configuration. Angara A7 Proposals exist for a heavier Angara A7, weighing 1133 tonnes and capable of putting 35 tonnes into a x 60° orbit, or delivering 12.5 tonnes to GTO with an enlarged KVTK-A7 as a second stage in place of the URM-2. There are no current plans to develop this vehicle as it would require a larger core URM-1 to carry more propellant and would have to await the development of the hydrogen powered engine for KVTK. The Angara A7 would also require a different launch pad. Angara-100 The Angara-100 was a 2005 proposal by Khrunichev to build a heavy-lift launch vehicle for NASA's Vision for Space Exploration. The rocket would consist of four RD-170-powered boosters, an RD-180-powered core stage, and a cryogenic upper stage using a modified Energia RD-0120 engine, the RD-0122. Its payload capacity to LEO would be in excess of 100 tons. Baikal Together with NPO Molniya, Khrunichev has also proposed a reusable URM-1 booster named Baikal. The URM-1 would be fitted with a wing, an empennage, a landing gear, a return flight engine and attitude control thrusters, to enable the rocket booster to return to an airfield after completing its mission. Specifications Active Cancelled or proposed Testing and manufacturing The production of the Universal Rocket Modules and the Briz-M upper stages will take place at the Khrunichev subsidiary Production Corporation Polyot in Omsk. In 2009, Polyot invested over 771.4 million RUB (about US$25 million) in Angara production lines. Design and testing of the RD-191 engine was done by NPO Energomash, while its mass production will take place at the company Proton-PM in Perm, Russia. Launches Facilities Angara will primarily be launched from the Plesetsk Cosmodrome. Beginning in 2020, , plans called for it to also be launched from the Vostochny Cosmodrome. This would have allowed the phase out of Proton, a rocket whose operation at Baikonur Cosmodrome, Kazakhstan has been objected to due to its use of large amounts of highly toxic UDMH and N2O4 and reliability issues.

The vehicle made its first flight on 25 August 2009. The flight was not successful, but the first stage operated as expected. A second launch on 10
