The Lockheed Martin "Polecat" was a private venture high-altitude, Unmanned Aerial System (UAS) flying wing development intended for data collection and research. Recording a first flight in 2005, the Polecat led a very short life cycle as it crashed on December 18th, 2006 when communications with the ground unit was lost. The project was terminated two days later. It was first showcased for public consumption at Farnborough Air Show 2006. It was known in company nomenclature as "P-175".
As built, the Polecat featured a wingspan of 90 feet. It grossed 9,000lbs when at rest and held a payload capacity for up to 1,000lbs of internally-held mission equipment. Power was through 2 x Williams FJ44-3E turbofan engines, each developing 3,010lbs of thrust output. This provided the aircraft with a service ceiling of up to 65,000 feet and a flight endurance window of up to four hours.
