The KVTK (
History
The KVTK was originally studied as an upper stage for the Energia family of rockets, but in 1987 was superseded by the RCS stage (Retro and Corrections Stage), based loosely on the American S-IVB. In 1996, consideration was briefly given to constructing a KVTK-derived Russian Propulsion Module for the International Space Station. Most likely, this module would have been transported to the ISS by a Space Shuttle.
On 10 December 2020, Roscosmos signed a 20.6 billion Russian ruble (US$279M as of December 2020) contract with Khrunichev to manufacture KVTK test models and flight test them by December 2025.[4]
In August 2021, Khrunichev announced that the first flight test of the KVTK is expected to occur in 2027 on an Angara-A5M launch vehicle.[5]
Variants
The KVSK (RCAF) would be a smaller cryogenic stage carrying 10,760 kilograms (23,720 lb) of propellant for the proposed Angara A3,[6] while the KVSK-A7 would be a larger stage loaded with 26,500 kilograms (58,400 lb) for the proposed Angara A7.[7]
