The Morane-Saulnier S and T were bomber aircraft developed in France in 1915 and produced in small numbers during World War I.[1][2]

Design and development[edit]

The Morane-Saulnier T was a large, five-bay biplane of conventional configuration, with unstaggered wings of equal span. The conical rear fuselage and large triangular vertical stabilizer were reminiscent of a scaled-up version of some Morane-Saulnier's smaller designs. The engines were mounted tractor-fashion in streamlined nacelles supported by struts in the interplane gap and the propellers on the Type T were often fitted with large spinners. The Renault's of the Type S were cooled with Hazet type side radiators. The landing gear consisted of two main units, each of which had two wheels joined by a long axle, plus a tailskid and an auxiliary nosewheel. Three open cockpits in tandem were provided: one in the nose for a gunner, and others for the pilot and a second gunner placed further back.[2]

Although initially designed as a bomber, the French Army ordered the type T in 1916 hoping to use it either as a bomber escort[2] or reconnaissance aircraft.[1][3] Only one example of the Type S was built, while an order was placed for 100 Type T aircraft, although only 60 or so of these were built before production was cancelled.[2]
