First MUOS satellite launched, second AEHF satellite delivered

The Navy's first Mobile User Objective System satellite, which launched successfully Feb. 24 from Cape Canaveral Air Force Station, Fla., and is scheduled to obtain initial capability along with its associated ground system this year, according to Lockheed Martin, the MUOS prime contractor and systems integrator.

The MUOS constellation will replace the Ultra High Frequency Follow-On system and give mobile warfighters improved communications capabilities such as simultaneous voice, video and data.

The Navy plans a four-satellite global constellation that should achieve full operational capability by 2015 and be able to extend UHF narrowband communications for a decade.

Lockheed Martin also announced Feb. 27 that it has delivered the second Advanced Extremely High Frequency (AEHF) military communications satellite to Cape Canaveral in preparation for an April launch into space aboard an Atlas V rocket.

The Air Force's AEHF system is a successor to the Milstar system, with one AEHF satellite capable of providing greater total capacity than the entire five-satellite Milstar constellation, the company said.

The AEHF system will support transmission of tactical military communications, including real-time video, battlefield maps and targeting data.

Lockheed Martin is under contract to provide four AEHF satellites and the mission control segment. Lockheed Martin is the prime contractor and systems integrator for AEHF, and Northrop Grumman is the payload provider.
