Budget document discloses existence of secret US Air Force UAV programme
Lockheed Martin's Skunk Works is believed to be developing a high-altitude, stealthy unmanned aircraft system (UAS) for the US Air Force (USAF) under
a secret programme, funded with money taken from the terminated Joint Unmanned Combat Air System (J-UCAS) project.
The existence of a classified air force UAS project was disclosed in a navy Fiscal Year 2007 budget document, which stated that the Pentagon
"directed the J-UCAS programme to split into two separate programmes: one air force classified programme and a navy UCAV [unmanned combat aerial
The new UAV, sometimes known as the Penetrating High Altitude Endurance (PHAE), is believed to be capable of operating at the 70,000-80,000 ft
altitudes used by the U-2. One report refers to the aircraft using engines from an inventory that has been in storage since the 1970s. This almost
certainly refers to the General Electric J97-GE-3 engine for the Teledyne Ryan AQM-91 Compass Arrow UAV (a project terminated in 1971). In 1998, a
NASA paper reported that 24 J97 engines were in storage at the agency's Ames research centre. The Compass Arrow exceeded 80,000 ft during tests, the
highest unclassified altitude ever recorded for a subsonic jet-powered aircraft. The J97 was rated at around 25 kN and the new UAV is probably a
The new UAV is much larger than the small stealth UAV that has been evaluated operationally in Iraq. That aircraft - believed to be powered by one or
two Williams FJ33 engines - has only eight hours' endurance, like DarkStar, and that is currently seen as inadequate.
