Operational history

In addition to operating from the carrier deck, the TS-1s served for several years in floatplane configuration aboard destroyers, cruisers, and battleships. The aircraft were slung over the side by

Squadron VO-1 operated this way from 1922, and VF-1 flew its float-equipped TS-1s from battleships in 1925 and 1926."United States Navy Aircraft Since 1911" by Gordon Swanborough & Peter M. Bowers (Naval Institute Press Annapolis, MD, ) 1976, 546 pp. The TS-1 was not universally liked by its crews. Positioning of the lower wing below the fuselage resulted in short wheel struts. This, and the wheels' placement close to each other, caused considerable problems with ground looping.
