History

• Big Crow program established in 1970 as a result
  of a US Army high power EW requirements study in
  support of SAM D (Patriot) radar system
  development
• 1971 1975 Army acquires/modifies NKC-135
  aircraft for airborne EW laboratory role
• 1976 the NKC-135 aircraft (Big Crow) begins
  supporting Patriot radar system
• 1976 1980 Big Crow begins supporting other
  programs (e.g., EWVA, OSD DVAL, E-3 AWACS) due to
  flexible system architecture

5
History

• 1980 Big Crow becomes 100 percent reimbursable
  organization
• 1985 Big Crow begins supporting US Navy AEGIS
  program
• 1995 Big Crow recognized as a unique National
  Asset
• 1995 DoD Reliance consolidates large EW aircraft,
  Big Crow directed to acquire second C-135
  aircraft
• 1999 Big Crow conducts instrumented airborne
  radar tracking of reentry of Ariane V Fuel tank

History

• 2000 Air Force retires ARIA telemetry fleet Big
  Crow given cruise missile chase mission by the
  Air Force
• 2001 Big Crow acquires Electro-optical mission
  upon retirement of Air Force Argus C-135 aircraft
• 2004 Big Crow develops multi-function,
  multi-spectral capability to support the
  Services, Treaty Organizations, and Coalition
  Allies in Research, Test and Evaluation and
  Training
