Lockheed Martin A2100 later increased to 2.55 m. The liquid apogee engine uses hydrazine fuel from the central tank along with nitrogen tetroxide oxidizer from two flanking tanks of 0.54 m diameter and up to 1.65 m long. Orbit maintenance is performed by the small hydrazine motors and ion thrusters. The maximum propellant supply (with the largest tanks at 95% fill factor) are 1368 kg of hydrazine fuel and 627 kg of nitrogen tetroxide oxidizer. According to Moog-ISP, the A2100 platform uses its LEROS bipropellant Liquid Apogee Engine. Lockheed Martin A2100 The A2100 is a communications satellite spacecraft model made by Lockheed Martin
