The severe program problems encountered by FIA in the early 2000s (decade) led to a plan to off-load radar reconnaissance to the Space Based Radar, later simplified to Space Radar, with initial launch anticipated around 2015.

Tracking and Data Relay Satellite System

TDRSSTDRSAtlantic Ocean Region
Early versions are believed to have used the Tracking and Data Relay Satellite System (TDRSS) to relay imagery to a ground station at White Sands, New Mexico.
As early as 1989, it was reported that an important function of TDRSS was to provide data relay for the Lacrosse radar imaging reconnaissance satellites operated by the National Reconnaissance Office.

According to former Director of Central Intelligence Admiral Stansfield Turner, Lacrosse had its origins in 1950 when a dispute between the Central Intelligence Agency and the U.S. Air Force as to whether a combined optical/radar reconnaissance satellite (the CIA proposal) or a radar-only one (the USAF proposal) should be developed was resolved in favor of the USAF.
