The first "pusher" to enter service during World War I was the Vickers Fighting Biplane 5. A two-seater, it was the first aircraft specifically designed as a fighter for the Royal Flying Corps. The first F.B.5 to reach France was delivered to 2 Squadron in February 1915 and 11 Squadron was equipped with F.B.5s in July 1915. Also known as the Vickers "Gunbus," it was armed with a moveable, forward-firing machine gun but it was vulnerable to attack from the rear. The F.B.5 was soon replaced by more advanced single-seat fighter aircraft like the Airco D.H.2.
