The L-class blimps were training airships operated by the United States Navy during World War II.

When the United States entered World War II, the Navy took over the operation of Goodyear's five commercial blimps.

As training airships these blimps operated mainly from the two major lighter-than-air bases, Lakehurst and Moffett Field.

In this role, L-8, of Blimp Squadron ZP-32 was involved in a mysterious incident wherein the airship came drifting in from the Pacific Ocean over southern San Francisco at Daly City on August 16, 1942, without either of the crewmen – Lt. E. D. Cody and Ensign C. Adams – on board.
