Lockheed Martin Polecat

The Lockheed Martin Polecat, company designation P-175, was an unmanned aerial vehicle built by Lockheed Martin and developed by its Advanced Development Programs division in Palmdale, California. The company funded it from its own money at the start of 2005 rather than with government funds, and the prototype was shown to the public at the 2006 Farnborough Airshow after about eighteen months of development. It was a large demonstrator with a wingspan of about 27 metres, two Williams FJ44-3E turbofan engines, and a payload capacity of about 450 kilograms of weapons or sensors, with an endurance of around four hours. Only one was built. On 18 December 2006 it crashed after a failure in the flight termination ground equipment triggered the aircraft's automatic fail-safe termination mode.
