USA-235
United States Space Force military communications satellite constellation
USA-235 , also known as Advanced Extremely High Frequency 2 or AEHF-2 , is a military communications satellite operated by the United States Air Force . It is the second of six satellite to be launched as part of the Advanced Extremely High Frequency program, which replaced the earlier Milstar system.[ 1]
Satellite description
The USA-235 satellite was constructed by Lockheed Martin Space , and is based on the A2100 satellite bus . The satellite has a mass of 6,168 kg (13,598 lb) and a design life of 14 years.[ 2] It will be used to provide super high frequency (SHF) and extremely high frequency (EHF) communications for the United States Armed Forces , as well as those of the United Kingdom, the Netherlands, and Canada.[ 1]
Launch
USA-235 was launched by United Launch Alliance , aboard an Atlas V 531 flying from Space Launch Complex 41 (SLC-41) at the Cape Canaveral Air Force Station (CCAFS). The launch occurred at 18:24 UTC on 4 May 2012,[ 3] first placing the satellite in a parking orbit of 185 kilometers by 905 kilometers. A second burn placed the satellite into a geostationary transfer orbit (GTO) with a perigee of 225 km (140 mi), an apogee of 50,031 km (31,088 mi), and 20.6° inclination .[ 4] The satellite was successfully deployed in this orbit 51 minutes after launch.[ 1]
