Skynet 5C represents the third installment in the series of four Skynet 5 military communications satellites managed on behalf of the British Ministry of Defence (MOD).

Launch

The deployment of Skynet 5C occurred on 12 June 2008 at 22:05:02 GMT, launched from French Guiana using an Ariane 5ECA launch vehicle. Although initially scheduled for 23 May, the launch was postponed due to software complications affecting the rocket. Originally manufactured as a ground spare unit, the decision to proceed with its launch was finalized in 2007. The launch operation was executed by Arianespace.

Spacecraft

Built by EADS Astrium under contract with its subsidiary Paradigm Secure Communications, which manages the satellite for the MOD, Skynet 5C utilizes the Eurostar E3000 platform. It possesses a launch weight of approximately 4,700 kilograms and is designed to function for around 15 years.

This satellite is integrated into a UK Ministry of Defence network providing nuclear-resistant military communication services operating in both X-band and UHF frequencies. Skynet 5C maintains its orbital position at 17.8 degrees West.
