  Milstar
Milstar is a series of advanced US military communications satellites designed to provide global jam-resistant communications for military users.
Milstar's "switchboard-in-the sky" operational concept was considered revolutionary because the satellites handle all processing and traffic management chores without ground station relays, greatly enhancing data security and jam resistance.
As more Milstar terminals were installed on various aircraft, ground vehicles, ships and military locations around the world, its role as a vital military command and control link continued to grow.

 Milstar (Military Strategic and Tactical Relay satellite)
An operational Milstar constellation is supposed to consist of four satellites, positioned around the Earth in geosynchronous orbits, but the program was, until recently, plagued with fiscal and technical problems.
However, the first of a new generation of Milstar satellites was placed in a useless orbit because of a flight software error in its Centaur upper stage during launch on April 30, 1999.
The second, third, and fourth Milstar 2 satellites were, however, successfully delivered into their intended orbits, on Feb. 27, 2001, Jan. 15, 2002, and Apr. 8, 2003, respectively, by Delta-4(01)B Centaur T launch vehicles.

 SPACE.com -- Final Milstar Reaches Orbit with Help of Titan 4B Rocket
The Milstar program was initiated in 1981 as a $42 billion "doomsday messenger" intended to provide the Pentagon with a survivable worldwide communications capability in the event of a six-month nuclear war.
As originally conceived, Milstar was to consist of 20 nuclear-hardened communication satellites, ground-based control stations and a variety of satellite terminals for the Army, Navy and Air Force.
Eventually the Milstar program was reduced in scope and its primary function changed, giving the U.S. the constellation it now has: two Milstar 1 spacecraft and three Milstar 2 spacecraft -- the last of which included the medium data rate capability.

 Milstar 3 Advanced Extremely High Frequency (AEHF) Military Communications Satellite
Option 1 (Milstar 2/Advanced EHF) would retain four Milstar 2 satellites, with a first launch in FY 1999 (as in the FY93 program), but it would eliminate the fifth Milstar 2 satellite (planned for delivery as a spare satellite in FY 2003) as well as subsequent Milstar-2 satellites.
The options containing four Milstar 2s were determined to be most preferable because a constellation of that size would meet military requirements and provide the most operational capability at the earliest date.
Reducing the weight of the Milstar II payload by a factor of three to four and providing a sufficient number of narrow-beam EHF antennas to connect the tactical forces needed to fight a regional conflict was a higher-risk, but potentially lower-cost, approach than the continued development of Milstar 2 satellites.
