The Lockheed Martin P-175 Polecat was a U.S. high-altitude long-endurance (HALE) unmanned aerial vehicle technology demonstrator developed by Lockheed Martin Skunk Works under a privately-funded internal research-and-development programme. First flown in 2005, the Polecat served as a Skunk Works UAV testbed for rapid-prototyping methodology, composite-airframe construction and autonomous flight-control technology. One airframe was built. The prototype was lost in a December 2006 test flight at the Tonopah Test Range, Nevada, after an autonomous flight-control malfunction. Lessons from the programme fed directly into later Lockheed Martin UAV work, including the RQ-170 Sentinel — the Skunk Works classified ISR UAV in service from around 2007 — and other classified and unclassified Lockheed Martin UAV efforts.

Polecat is a flying-wing HALE design with a wingspan of roughly 90 ft (27.4 m). Empty weight was about 9,000 lb and maximum take-off weight 12,000 lb. Power came from two Williams FJ44-3A turbofans rated at roughly 3,000 lbf each. Top speed was around 460 mph (Mach 0.6), service ceiling roughly 65,000 ft, and range about 4,000 nmi. Construction relied heavily on composites, and the airframe carried an autonomous flight-control system together with sensor and payload integration provisions intended for ISR and other classified missions. As a Skunk Works HALE UAV demonstrator, Polecat laid the groundwork for the classified UAV programmes that followed.

For Kids — a shorter, friendlier version

The Polecat was a secret high-altitude drone. Lockheed's Skunk Works built it in 2006. Its job was to test stealth ideas for future drones. The Polecat could fly very high, up to 65,000 feet, and stay airborne for hours.

The Polecat has two small jet engines. Top speed is about 380 mph, faster than most cars on a highway. The drone has a 90-foot wingspan, longer than a Boeing 737. The body has a stealthy V-shape with no tail. It looks like the F-117 and B-2 stealth jets.

The Polecat first flew in late 2005. It used Lockheed's secret California test base. The drone tested how to build cheap stealth parts from carbon fiber. The Polecat made several test flights at high altitude.

The Polecat crashed during a flight in December 2006. The drone's flight system had a problem. The team had to destroy the plane safely. Skunk Works learned a lot from the Polecat. Those lessons helped with later drones like the RQ-170 Sentinel.

Fun Facts

  • The Polecat was a secret Lockheed Skunk Works stealth drone, built in 2006.
  • Top speed is about 380 mph, faster than most cars on a highway.
  • The Polecat has a 90-foot wingspan, longer than a Boeing 737.
  • It flew up to 65,000 feet, almost three times higher than airliners.
  • Only one Polecat was built; it crashed during a test flight in December 2006.
  • The Polecat's lessons helped Lockheed build the RQ-170 Sentinel.
  • Lockheed funded the Polecat with its own money, not government funds.

Kids’ Questions

Why fly so high?

Above 60,000 feet, there is almost no weather, few clouds, and very little other air traffic. A drone up there can watch large areas of ground for many hours without being bothered. It is also harder for enemies to shoot down a drone flying that high. The Polecat tested if a stealth drone could work at these high altitudes.

Why did Lockheed pay for it themselves?

Lockheed wanted to develop stealth drone technology before the government asked for it. By paying for the Polecat with its own money, Lockheed kept the design secret from competitors and was ready when the government wanted stealth drones. This pattern (called Skunk Works style) has helped Lockheed win many secret projects.

What replaced it?

The Polecat's ideas lived on in later Lockheed stealth drones. The RQ-170 Sentinel (the stealthy 'Beast of Kandahar' that spotted Osama bin Laden) used some Polecat design elements. The future Skunk Works drone programs may use even more. The Polecat itself was just a test plane, never meant for combat.

Variants

P-175 Polecat (single prototype, 2005-2006)
Sole technology-demonstrator airframe. First flight in 2005; lost December 2006 at Tonopah Test Range, Nevada, after an autonomous flight-control malfunction. Roughly 13 months of flight testing covering composite-airframe, autonomous-flight and HALE-UAV technology demonstration.

Notable Operators

Lockheed Martin Skunk Works (developer / operator)
Sole operator. Privately-funded internal R&D programme running through 2005-2006, with Polecat technology feeding the classified UAV programmes that followed.
Subsequent Lockheed Martin UAV programmes (heritage)
Later Lockheed Martin Skunk Works UAVs that drew on the Polecat foundation, including the RQ-170 Sentinel (classified ISR UAV in service from around 2007) and other classified and unclassified Lockheed Martin UAV programmes through 2026.

Frequently Asked Questions

Why did Lockheed Martin develop Polecat privately?

Skunk Works wanted to prove a rapid-prototyping route for HALE UAVs without waiting on a U.S. government contract. Funding the demonstrator internally gave Lockheed Martin three advantages: faster turnaround than a contracted programme, full retention of the resulting intellectual property, and a flying article to back future UAV proposals. Polecat data and methodology then carried directly into Lockheed Martin's later classified and unclassified UAV pitches, repaying the company's engineering investment through follow-on programme wins.

Why was Polecat lost?

An autonomous flight-control malfunction. During a December 2006 test flight at Tonopah Test Range, Nevada, the flight-control system failed and the vehicle was lost. The root cause traced back to immaturity in autonomous-flight-control software and sensor integration as they stood in the 2005-2006 timeframe. Later Lockheed Martin UAV programmes incorporated the lessons learned about autonomous flight-control and sensor integration, and the loss did not derail the broader Skunk Works UAV development trajectory.

What followed Polecat?

Classified Lockheed Martin UAV programmes. The RQ-170 Sentinel entered U.S. Air Force service from around 2007 as a classified ISR UAV, and was reportedly used for surveillance during the 2011 Bin Laden raid among other classified operations. Other classified and unclassified Lockheed Martin UAV programmes have continued through 2026, all drawing on the Polecat technology foundation.

How does Polecat compare to Northrop Grumman Global Hawk?

They are different programmes at different stages. The RQ-4 Global Hawk is a Northrop Grumman operational HALE ISR UAV with around 42 airframes in U.S. service plus foreign operators. Polecat was a single Lockheed Martin Skunk Works technology demonstrator, lost in 2006. Global Hawk has a long operational record; Polecat sits in the Skunk Works HALE UAV demonstration lineage that fed later classified Lockheed Martin programmes.
