From The Space Library

Because development of military rigid airships by the Navy was considered proper, and one logically leading to the development of commercial types, the NACA urged adequate funding of the Navy program in spite of recent airship disasters.

Navy approved installation of J. V. Martin retractable landing gear on VE-7 Vought airplane, but no evidence indicates it was done. First U.S. retractable landing gear was used by J. V. Martin K-III in 1918-19 period.
