The Morane-Saulnier T (or Morane-Saulnier MoS.25 A.3) was a French biplane reconnaissance aircraft in 1916 and produced in small numbers during World War I.
The Morane-Saulnier T was a large, five-bay biplane of conventional configuration, with unstaggered wings of equal span. The tapered rear fuselage and large triangular vertical stabilizer were reminiscent of those used on Morane-Saulnier's smaller designs but would be a constant cause of problems throughout the types operational service despite attempts to fix the problems. The tractor engines were mounted in streamlined nacelles supported by struts suspended between the wings and the propellers on the Type T were sometimes fitted with large spinners. 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, with one gunner in the nose, and another behind the wing, while the pilot was under the top wing.
Although the similar but larger Type S was designed as a bomber, the French Army ordered the type T in 1916 as a reconnaissance aircraft. Only one example of the preceding Type S bomber had been built, while an order was placed for 90 Morane-Saulnier T aircraft, although older sources suggest that production may have been cancelled before all of these were completed.[1]
