Launch

It was launched from French Guiana aboard an Ariane 5ECA carrier rocket at 22:05:02 GMT on 12 June 2008. 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

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.[1]

Skynet 5C is located at 17.8 degrees West.
