The S400 is a family of pressure fed

rocket engines manufactured by ArianeGroup (former Airbus DS) at the Orbital Propulsion Centre[3]
in Lampoldshausen, Germany.

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]
