caption_attribution_description: English: A U.S. Navy Martin SC-1 torpedo plane in 1925. Curtiss built only six CS-1 and two CS-2 but Martin produced 35 CS-1 as SC-1 and 40 CS-2 as SC-2.
context_page_description: The Curtiss CS was a reconnaissance and torpedo bomber aircraft used by the United States Navy during the 1920s. It was a large single-engine biplane with single-bay unstaggered wings, the design conventional in all respects other than that the lower wing was of greater span than the upper. The CS was built to allow its undercarriage to be quickly and easily interchangeable between wheeled, tailskid undercarriage, and twin pontoons for operation from water. Provision for the carriage of a torpedo was semi-recessed into the underside of the fuselage, blended in behind an aerodynamic fairing. The pilot and gunner sat in tandem open cockpits, while accommodation inside the fuselage was provided for a third crewmember who served as bombardier and radio operator. This station was also provided with a dorsal hatch aft of the gunner's position, and a ventral blister aft of the torpedo recess, which was used for aiming bombs or torpedoes.
