The '''Martin S''' was a two-seat observation [[seaplane]] produced by the [[Glenn L. Martin Company]] in the United States in 1915.<ref name="JEA">Taylor 1989, 635</ref> Designed along the same general lines as the preceding [[Martin T|Model T]],<ref name="IEA">''The Illustrated Encyclopedia of Aircraft'', 2432</ref> it was a largely conventional two-bay biplane with unstaggered wings of equal span. The fuselage was not directly attached to the lower wings, but was carried on struts in the interplane gap. The undercarriage consisted of a single large pontoon below the fuselage and outrigger floats near the wingtips.<ref name="JEA" /> The Model S was 23-year-old [[Donald Wills Douglas, Sr.|Donald Douglas]]' first and only design for the Martin company, and it set three world altitude records and a flight duration record that stood for three years.<ref name="COF">"The Early Years of Douglas Aircraft, the 1920s"</ref>
Six, possibly fourteen, of these aircraft were operated by the [[Aviation Section, U.S. Signal Corps]],<ref name="dispute">Aero Files states six, and Baugher corroborates their serial numbers (S.C. 56-59, 94-95), while Taylor states fourteen. No additional serials for Martin S are given in Baugher. Aero Files does not list any aircraft for the Navy.</ref> and another two by the [[United States Navy]].<ref name="JEA" /><ref name="IEA" /> All of the Army aircraft, S.C. 56-59 and 94-95, were assigned to the first U.S. aviation unit based overseas, the [[2d Air Refueling Squadron|1st Company, 2d Aero Squadron]] at [[Fort Mills]], [[Corregidor]], in March and April 1916, where they used a radio transmitter with a range of 29 miles to adjust battery fire for the Coast Artillery.<ref name="hennapp14">{{cite web|last=Hennessey |first=Juliette |year=1958 |url=http://www.afhra.af.mil/shared/media/document/AFD-090602-017.pdf |title=The United States Army Air Arm, April 1861 to April 1917 |work=USAF Historical Study No. 98 |publisher=AFHRA (USAF) |access-date=6 Mar 2011 |url-status=dead |archive-url=https://web.archive.org/web/20110722182357/http://www.afhra.af.mil/shared/media/document/AFD-090602-017.pdf |archive-date=2011-07-22 }}, pp. 152 and 165.</ref>
