The P-791 is an experimental aerostatic/aerodynamic hybrid airship developed by Lockheed-Martin corporation. The first flight of the P-791 was on 31 January 2006 at the company's flight test facility on the Palmdale Air Force Plant 42. It has a unique tri-hull shape, with disk-shaped cushions on the bottom for landing. A very similar design can be seen in the Long-Endurance Multi-intelligence Vehicle (LEMV).Click here to see the video:

Hi folks,
The P791 did not impress the military experts as it suffered from a yaw/roll oscillation that looks like dutch roll and there was also a nasty harmonmic oscillation from one hoverpad to another. Both faults are clear in the original U tube clip of a landing.
Hybrid Air Vehicles and Northrop Grumman won the 517 million LEMV contract and first flight of the HAV 304 will be late summer.
