Legacy Satellite Communications (Legacy SATCOM)

ULTRA-HIGH FREQUENCY FOLLOW-ON (UFO) PROGRAM
UFO is a constellation of six on-orbit geosynchronous satellites that provides tactical narrowband UHF satellite communications to the Defense Department and other government agencies. UFO achieved Initial Operational Capability in 1993 and Full Operational Capability in 2000.

- Communications satellite system

- Consists of space and satellite control segments

- Designated Navy ACAT 1C program

- Program in the operations support phase

- Six satellites

 

 

 

 

 

FLEET SATELLITE (FLTSAT)
An outgrowth of the Lincoln Experimental Satellite series and TACSAT-1, FLTSAT was developed by the Navy to be the first complete operational system in space to serve the tactical user.

- Two FLTSATs remain on orbit

- FSC-7 launched in 1986 and FSC-8 launched in 1989

- Original five-year design life but the satellite bus on both are healthy and have sufficient fuel reserves

- 30 – 25kHz channels, 5 – 5kHz channels

- Provides critical augmentation to the UFO system

- Both FLTSATs are equipped with a FLTSAT Extremely High Frequency (EHF) Package

- Served as an in-orbit resource for conducting thorough and  Served as an in-orbit resource for conducting thorough and realistic test and evaluation of the MILSTAR EHF communications  system. The Fleet EHF Package was turned off in 2007.

 

SKYNET
Skynet refers to the commercial lease agreement of UHF services on the Skynet 5C Satellite.

- In August 2007, the Deputy's Advisory Working Group briefed the Deputy Secretary of Defense on pursuing a commercial lease agreement for UHF satellite communications services.

- In January 2008, PMW 146 was directed to procure a sole source firm-fixed-price contract to Intelsat General Corp., to lease UHF services on Skynet 5 in FY09 In January 2008, PMW 146 was directed to procure a sole source firm-fixed-price contract to Intelsat General Corp., to lease UHF services on Skynet 5 in FY09

LEASED SATELLITE (LEASAT, no longer in service)
LEASAT was a dedicated Defense Department UHF satellite in use from 1990 to 2015. The satellite reached its end of life in September 2015.

- Dedicated Defense Department UHF satellite commercially built and operated

- Launched in 1990 aboard Shuttle Columbia Launched in 1990 aboard Shuttle Columbia

- LEASAT 5 reverted to Intelsat (formerly Hughes) in February 1997  LEASAT 5 reverted to Intelsat (formerly Hughes) in February 1997 upon expiration of Navy lease
