H-class blimp
1921 blimp of the United States Navy
The H class blimp was an observation airship built for the U.S. Navy in the early 1920s. The original "H" Class design of 1919 was for a twin engined airship of approximately 80,000 cubic feet volume. Commander Lewis Maxfield (who was to have commanded the ZR-2, better known as the R38, and died in its crash) suggested that a small airship which could be used either as a tethered kite balloon, or be towed by a ship until releasing its cable, would be able to scout on its own.[1] The concept was an airship similar to the later Army Motorized Kite Balloons.
