TheZenit-2M,Zenit-2SB,Zenit-2SLBorZenit-2FGwas aUkrainian expendable carrier rocketderived from theZenit-3SL.It was a member of theZenitfamily ofrockets,which were designed by theYuzhmash.

Development[edit]

The Zenit 2M was a modernised version of theZenit-2,incorporating modifications and upgrades made to the design for theSea Launchprogramme.

Launches of Zenit-2M rockets were conducted fromBaikonur Cosmodrome Site 45/1.Commercial launches are conducted byLand Launch,and use the designation 2SLB, however as of 2011, no commercial launches have been ordered and no launch of 2SLB has taken place as of 2023. Launches conducted byRoskosmosor theRussian Space Forcesuse the designation 2M. The designation 2SB can also be applied to the rocket when it is being used as part of a larger vehicle, such as theZenit-3SLB.

The first launch of a Zenit-2M occurred on 29 June 2007, carrying the lastTselina-2 ELINTsatellite for theRussian Space Forces,Tselina-2 satellites having been previously launched by older Zenit-2 rockets.^[4]The second launch, carrying theFobos-GruntandYinghuo-1spacecraft, was conducted on 8 November 2011, using a modified configuration designated theZenit-2FG.This configuration incorporated the payload fairing used on theZenit-3Frocket, and a special adaptor for the Fobos-Grunt spacecraft, which incorporated aFregat-derived propulsion system. The Zenit-2 and Zenit-2M, however, were supplanted by theZenit-3SLBafter 2008.
