A "parasol" monoplane, the Morane Saulnier Type L was a fragile two-seat reconnaissance aircraft. It was the first aircraft armed with a fixed machine gun that fired through the propellor arc. Bullets which struck the propellor were deflected by steel plates. Armed with a Hotchkiss machine gun firing 8 mm solid copper bullets, Roland Garros tested the design in April 1915. He scored three victories in three weeks before the plane was captured by the Germans.
On 7 June 1915, flying a Morane Saulnier Type L (3253), Sub-Lieutenant R A J Warneford attacked and destroyed a German Zeppelin (LZ37) over Ghent, Belgium. For this action Warneford received the Victoria Cross.
