This is a modification of the R-29RM (SS-N-23) for launching commercial satellites. The rocket is based on the basic missile with forward mounted payloadfairing replacing the four reentry vehicles on the back side of the 3rd stage/PBV. The Shtil-2.1 features an extension of the aerodynamic fairing for front-mounted payload offering a larger payload volume, but retains the capability of submarine launch.
The Russian Ministry of Defense in 2010 retracted the offer to make R-29 based missiles available as space launchers, effectively cancelling all future Shtil missions.
