The year 1929 saw the creation of the U.S. Navy airship ZMC-2, the first metal dirigible (aluminum alloy) of its kind:
“Heretofore, the trend in dirigible construction has been toward larger and longer ships; the egg-shaped ZMC-2 can withstand the buffeting of the winds much better than her larger and more unwieldy sister ships.”
Built by the Aircraft Development Corporation (Detroit), ZMC-2 was in use by the U.S. Navy until her retirement, in 1941.
