     Mission Description:

     UHF systems support tens of thousands of stationary and mobile users ashore and afloat. The UFO satellite system will replace the Fleet Satellite Communications (FLTSATCOM) and the Leased Satellites (LEASAT), which provide links between naval aircraft, ships, submarines and ground stations, and between strategic air headquarters and the National Command Authority (NCA) network. UFO will improve UHF protection against electronic threats and provide an interim Global Broadcast Service (GBS) capability via onboard GBS transmitters on satellites F8 - F10.

  Key Program Factors:

Provides ship-to-shore, fleet broadcast and other priority UHF communications links for tactical users, low-intensity conflict (LIC), and special operations; maintains DoD's world-wide UHF communications capability; ensures interoperability with most existing UHF terminals; provides secure and jam-resistant telemetry, tracking and command (TT&C) functions; provides jam-resistant uplinks (fleet broadcast); electromagnetic pulse (EMP) -protected. Will support 10,000+ manpack, ship, airborne, and mobile and fixed ground UHF terminals

Acquisition Service and Category: Navy, ACAT-1C

Initial Operational Capabilities (IOCs): UHF in 1Q/FY 1994; EHF in 3Q/FY 1995

Satellites F4 - F10 also carry a Milstar-compatible EHF package with enhanced anti-jam and command, broadcast and interconnectivity communication capabilities

Network Control: Demand Assigned Multiple Access (DAMA) controllers will maximize use of 5- and 25-kHz channels to meet user needs.
