Block DM-SLB

Block (US) DM-SLB is developed on the basis of Block DM-SL developed and manufactured by S.P. Korolev RSC Energia, which was successfully used in the Sea Launch program.

It is intended for injection of different purpose spacecraft into high elliptical, high circular (including geo-stationary) orbits and departure (inteplanetary) trajectories.

The structure of the Block DM-SLB used in the Zenit-3SLB launch vehicle in many respects is similar to the Block DM-SL structure of the Sea Launch project and it is its adapted option for the Land Launch Program.

The Upper Stage using liquid oxygen and kerosene as the propellant components can provide up to three engine burns throughout the mission. Therefore the spacecraft injection into geo-stationary orbit is provide in compliance with two-or three-burn sequence depending on the longitude of SC point.
