The P-791 is an experimental hybrid airship project developed by Lockheed Martin’s Advanced Development Programs aka Skunk Works. A testbed for future large transport craft, the P-791 features a number of design features developed to ensure “the best of both worlds” meaning that the P-791 can carry massive amounts of cargo just like a normal airship but travel for more than 12,000 miles at speeds close to 100 knots and use normal runways, thus eliminating the complicated ground operations that limit conventional airships.
