Hypersonic flight is defined as aerodynamic flight at speeds of Mach 5 or greater, and use of surplus Phoenix missiles is one of the methods being considered to obtain critical flight data in the hypersonic regime.

These missions, to be conducted over restricted military test ranges, would involve launching a missile from a NASA F-15 aircraft flying at speeds up to Mach 2.0, with the missile then accelerating to speeds up to Mach 5.0, depending on its trajectory, before fuel is exhausted. The missiles would carry experimental research payloads into the hypersonic regime, something that is currently difficult to achieve.

The Phoenix missiles used for hypersonic research will have their explosive warheads removed and their tracking and guidance systems replaced with a smaller, more lightweight guidance system. The missiles will also be heavily instrumented to obtain and transmit test data from experiments in such areas as thermal protection materials, scramjet propulsion, guidance & control, boundary layer transition and aerodynamics at hypersonic speeds.

As part of the preliminary studies, several "captive-carry" flights will be flown by the F-15 with an inactive missile with no propellant carried on the aircraft's centerline pylon to determine the performance of the aircraft when carrying the missile. The project has not been funded to conduct actual launches to obtain hypersonic flight test data, and a decision on funding such research is not expected before 2008.

When in military service, the Phoenix missile was the primary long-range air-to-air weapon carried by the Navy's now-retired fleet of Grumman F-14 aircraft. It was the first operational radar-guided air-to-air missile that could be launched in multiple numbers against different targets from an aircraft. The missile was in operational service with F-14 squadrons from 1974 through its retirement in late 2004. The Navy has no current need for the remaining supply of Phoenix missiles and is making several available to NASA for its hypersonic research efforts.

Thomas Jones of NASA Dryden Flight Research Center is the principal investigator for the development of the Phoenix missile hypersonic testbed. This testbed development effort is funded by the Hypersonics Project under the Fundamental Aeronautics Program of NASA's Aeronautics Research Mission Directorate.
