During the second international aero meet, held at Wiener Neustadt in June 1913, Roland Garros won the precision landing prize in a Type H.[3] Later that same year, a Morane-Saulnier H was used to complete the first non-stop flight across the Mediterranean, from Fréjus in the south of France to Bizerte in Tunisia.

[2] French-built machines saw limited service in the opening stages of World War I, with pilots carrying out reconnaissance missions and occasionally engaging in aerial combat using revolvers and carbines.

[2] The British Royal Flying Corps also acquired a small number, impressing three civilian-owned aircraft on the outbreak of the war, and ordering 36 machines Grahame-White, who was manufacturing the type in the UK under licence in two batches.

[5] A German-built copy entered production as the Fokker M.5 in 1913: it featured a slightly longer fuselage, framed in steel tube rather than wood, a comma shaped rudder, and a redesigned undercarriage integrated with the under-wing bracing pylons.

[6] The type was also produced under licence in Germany by the Pfalz Flugzeugwerke: during the war the company built armed versions as the E.I, E.II, E.IV, E.V, and E.VI, with increasingly powerful engines.
