Envelope expansion will clear nozzle operation to 6.5g, 2.0 Mach, 1600 psf dynamic pressure, and 30 degrees angle-of-attack, allowing adequate capability to meet the research requirements. The F-15 ACTIVE program is managed by the NASA Dryden Flight Research Center located at Edwards Air Force Base, California. The prime contractors for the program are Pratt and Whitney (P&W), a division of United Technologies, West Palm Beach, Florida and McDonnell Douglas Aerospace (MDA), St. Louis, Missouri.
