The Lockheed Martin Polecat (company designation P-175) was an unmanned aerial vehicle by Lockheed Martin. It was developed by the company's Advanced Development Programs division in Palmdale, California .

Design and development

Designated P-175, the Polecat was funded internally by Lockheed Martin (as opposed to using United States Government funds) at the beginning of 2005. The prototype was unveiled at the 2006 Farnborough Airshow.[1][2] It was developed over a period of 18 months.[3]

On December 18, 2006, the aircraft crashed due to an "irreversible unintentional failure in the flight termination ground equipment, which caused the aircraft's automatic fail-safe flight termination mode to activate."[4]
