USA 115, a US military Milstar communications satellite, was launched from Cape Canaveral aboard a Titan 4 rocket. Milstar is a series of advanced US military communications satellites designed to provide global jam-resistant communications for military users. The Milstar system, when complete, will consist of four Block 2 satellites in low-inclination, geosynchronous orbits. The operational system will accomodate direct links to numerous, highly mobile Milstar ground terminals installed on vehicles, ships, submarines and aircraft. The first two Block 1 spacecraft, launched in 1994 and 1995, will eventually be replaced by the Block 2 Milstar 3 through 6, which are scheduled for launch beginning in 1999. When the full Block 2 constellation is deployed, as many as 10,000 users will be able to access the system at any given time.
