First of a family of liquid propellant rocket engines manufactured by Moog-ISP at Westcott, Buckinghamshire, United Kingdom. LEROS engines have been used as primary apogee engines for telecommunications satellites such as the Lockheed Martin A2100 as well as deep space missions such as Juno. The LEROS 1 was developed and qualified in the 1990s by Royal Ordnance, later part of British Aerospace. The LEROS engines are made of niobium alloy, which is traditionally used for liquid rocket engines such as the main engine of the Apollo Lunar Module. More than 70 LEROS 1 series engines have been delivered and have flown successfully as of 2015.
