=== Airships ===
Although aircraft, pre-World War II rigid airships were commissioned (no different from surface warships and submarines), flew the U.S. ensign from their stern and carried a United States Ship (USS) designation.

Rigid airships:

* ZRS: Rigid airship scout <ref name=Akron group=A>See [[Akron-class airship]].</ref>
* [[ZRCV]]: Rigid airship aircraft carrier, proposed, not built

Lighter-than-air aircraft (e.g., [[blimp]]s) continued to fly the U.S. ensign from their stern but were registered as aircraft:
