Skynet 5C is the third of four Skynet 5 military communications satellites to be used by the British Ministry of Defence (MOD).

Launch[edit]

It was launched from French Guiana aboard an Ariane 5ECA carrier rocket at 22:05:02 GMT on 12 June 2008.[1] The launch was originally scheduled for 23 May, but was delayed to 30 May, and then delayed again due to software problems with the carrier rocket. Originally built as a ground spare satellite, the decision to launch was made in 2007. Arianespace provided launch services.

Spacecraft[edit]

It was constructed by EADS Astrium under a contract to its subsidiary company Paradigm Secure Communications, who will operate the satellite on behalf of the MoD. Based on the Eurostar E3000 satellite bus, it has a mass of 4,700 kilograms, and an expected on-orbit lifetime of 15 years.[2]

Skynet 5C is part of a constellation of communications satellites for the United Kingdom Ministry of Defense that supports nuclear hardened and protected military X-band and UHF frequency capabilities.[3]

Skynet 5C is located at 17.8 degrees West.[4]
