The S400 is a family of pressure fed
in Lampoldshausen, Germany.They burn
ExoMars Trace Gas Orbiter or Jupiter Icy Moons Explorer.[1]
The S400 family has had an extensive history in the commercial telecommunication market. Its first launch was aboard the
bipropellant rocket
propulsion system. It also was the first European communications satellite system.
This family of engines have displayed a remarkable competitiveness, still winning many designs (for 2015, it is expected to fly on Sicral 2, ARSAT-2, Hispasat AG1 and MSG-4.[1][4]
