The F class of US Navy blimps comprised a single airship, built during World War I by Goodyear as one of a group of three small blimps offered to the US government.

The Navy blimps were designated E-1, F-1, and the Army airship A-1.

Classified as an "Experimental Engine Testing Dirigible."

F-1 had the same envelope size as the E-1, due to the use of a tractor mounted 125 hp Union engine, the performance was different.

F-1 spent its entire career at Hampton Roads (Norfolk, Virginia).
