The Martin T was a training biplane produced in the United States in 1913 for military use.[1] It was a conventional, three-bay biplane with unstaggered wings of equal span. The pilot and instructor sat in tandem, open cockpits with dual controls. Fixed, tricycle undercarriage was fitted which could be exchanged for a single pontoon under the fuselage and wingtip floats.[2]

Early examples were delivered to the Army without engines, so that the Army could power them with engines salvaged from other aircraft, but later TTs came equipped with Curtiss, Hall-Scott, or Sturtevant engines.[3]

In 1915, a Model TT was piloted by Oscar Brindley to win the Curtiss Marine Trophy for the longest flight within ten consecutive hours in the one day, covering 444 mi (710 km).[3]

The Model T was the basis for the Martin S Hydro seaplane, with a lengthened fuselage, a greater span, and upper wing ailerons.
