Skynet 5D is a military communications satellite operated by Airbus Defence and Space on behalf of the British Ministry of Defence. It was the last of four Skynet 5 satellites to be launched.
The Skynet 5D spacecraft was constructed by Astrium, based on the Eurostar 3000S satellite bus. It had a mass at launch of approximately 4,800 kilograms (10,600 lb), and is designed to operate for at least 15 years.[1] Its 34-metre (112 ft) solar arrays will generate a minimum of 6 kilowatts[2] to power its UHF and X-band communications systems. The satellite's payload includes jamming countermeasures.[3]
The Ministry of Defence described the satellite as having a "key role in gathering intelligence on operations", as well as communications.[4]
