Records concerning the history of French airships in US Navy service are fragmentary. A number of airships of various classes were operated by the US Navy (USN) during World War I from the French Naval Base at Paimbœuf, which was designated a US Navy Air Station from 1 March 1918 onward. It appears that at least 13 French manufactured airships were operated by the USN from Paimbœuf; six were eventually shipped to the United States and one was returned to France before the armistice. The Navy operated or ordered four Astra-Torres type airships, one T-2—the Captain Caussin, two CM types, and three or four VZ types.
