Skynet is a family of military satellites, which provide strategic communication services to the three branches of the British Armed Forces and to NATO forces engaged in coalition tasks. [23] In 2013, new types of Skynet terminals were delivered, utilising Skynet's new Internet Protocol (IP) based modular
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]
The US Armed Forces maintains international networks of satellites with ground stations located in various continents. Signal latency is a major concern in satellite communications, so geographic and meteorological factors play an important role in choosing teleports. Since some of the major military activities of the U.S. army are in foreign ...
Skynet 5B was launched by an Ariane 5ECA carrier rocket flying from ELA-3 at Kourou. The launch occurred at 22:06 UTC on 14 November 2007.

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 ...
Skynet 5A had a launch mass of 4.7 tonnes, and operates with a payload power of 5 kilowatts, four times more than the previous-generation Skynet 4 satellites. It is operated by Paradigm Secure Communications , a commercial organisation which is a wholly owned subsidiary of EADS Astrium , on behalf of the United Kingdom's Ministry of Defence .
