The Lockheed Martin LMH-1 / P-791 was a hybrid airship developed by the company to satisfy the United States Army's "Long-Endurance, Multi-Engine Vehicle" (LEMV) program. The design utilized a combination of aerodynamic and aerostatic lift principles but was passed on in favor of the competing Northrop Grumman HAV-3 (Hybrid Air Vehicles). Lockheed continued hybrid airship development in the subsequent "LMZ1M".
The LMH-1 was powered by four V6 diesel-fueled engine units each developing 300 horsepower and driving three-bladed propeller units. The aircraft itself had a futuristic design with its rounded, streamlined shape and cut-off bottom. Tailfins were arranged at the rear in an "X" pattern.
Some attempts were made to bring the airship to the commercial market as a cargo carrier including a deal with Straightline Aviation and Hybrid Enterprises (LMH-1) but these initiatives appear to have fallen to naught.
