Breeze M Upper Stage

Breeze M upper stage is used in the Proton M and  will be used in future Angara launch vehicles. This upper stage can support spacecraft injection into a low, medium-height or high GSO. An option is available without any add-on tank. 

Integration of Breeze M in the Proton M launch vehicle allows the weight of a payload to be injected into geostationary orbit to be brought up to 3700kg .

A Proton M/Breeze M stack was first launched on April 7, 2001 .
