The Royal Aircraft Factory A.E.3 (Armed or Armoured Experimental), also known as the Farnborough Ram, was a prototype British armoured ground attack aircraft of the First World War. The A.E.3, which was a development of the Royal Aircraft Factory's N.E.1 night fighter, was a two-seat single-engined pusher biplane. Three were built in 1918, but the type was unsuccessful, with no further production ensuing.
