The Stalker is a hand-launched, electrically-powered unmanned aerial vehicle developed by Lockheed Martin Skunk Works for an unspecified customer, presumably United States Special Operations Command.
Design and Development
The Lockheed Martin Stalker was created in 2006 by the same Skunk Works team responsible for the Desert Hawk. It is hand launched and belly landed, has a quiet electric motor and propeller, and carries a detachable camera payload. The camera system has modules for daylight, low light, and infrared. The camera system can be removed and replaced with droppable payloads.
A propane fuel cell powered version of the Stalker with 8 hours endurance (quadruple the 2 hours available on battery power) has been developed.
In July 2012, a Stalker demonstrated, in a wind tunnel test, a capability of in excess of 48 hours continuous flight while being powered by a ground-based laser system. Following the wind tunnel test, Lockheed and LaserMotive Inc. performed a series of outdoor tests with the laser powering system the next month. The flight tests went successfully, and accomplishments included:
An extended model of the Stalker was also built with the following characteristics :
