[SatNews] The Lockheed Martin (NYSE:LMT) A2100 commercial communications satellite fleet has achieved a major milestone by accumulating 300 years of successful in-orbit operations.

The A2100 satellite series, designed and manufactured at Lockheed Martin Commercial Space Systems (LMCSS), currently consists of 37 commercial communication satellites featuring 1400 transponders with an accumulated lifetime of over 11,000 years of successful operations in orbit.

The first A2100 satellite, GE-1 (now known as AMC-1), was launched Sept. 8, 1996, and has surpassed 14 years of service life. BSAT-3b, the most recent A2100 spacecraft, was launched Oct. 28, 2010 for the Broadcasting Satellite System Corporation (B-SAT) of Japan. The satellite was handed over for operation to B-SAT on Dec. 8, 2010. Throughout its 52-year history, Lockheed Martin Space Systems Company has built 98 commercial communications geostationary earth orbit satellites which have achieved a total of 921 in-orbit years.

The Lockheed Martin A2100 geosynchronous spacecraft series is designed to meet a wide variety of telecommunications needs including Ka-band broadband and broadcast services, fixed satellite services in C- and Ku-band, high-power direct broadcast services using the Ku-band frequency spectrum and mobile satellite services using UHF, L-, and S-band payloads. The A2100's modular design features simplified construction, increased on-orbit reliability and reduced weight and cost. The A2100 design accommodates a large range of communication payloads and serves as the platform for critical government communications programs, including the Advanced Extremely High Frequency and Mobile User Objective System satellites. The A2100 spacecraft can also be configured for missions other than communication. It has been adapted for Lockheed Martin’s Geostationary Operational Environmental Satellite Series-R zEarth observing mission and serves as the spacecraft platform for Lockheed Martin’s GPS III program.
