PERFORMANCE

RELIABLE. FLEXIBLE. EFFICIENT

The 2-stage medium class vehicle serves the 3.5 to 5 Metric Tons satellite class and is ideal for launching multiple spacecraft at once.  With only the replacement of the third stage with a metallic interstage, the Proton Medium is identical to the heritage and flight proven Proton Breeze M – the workhorse that has been in service since 1965 with 416 launches to date.  The simplified modification approach to the launch vehicle allows to minimize and streamline necessary changes to the Cosmodrome ground support hardware and launch pad tower.
