Royal Aircraft Factory F.E.2b and F.E.2d
Type: two-seater fighter (later night-bomber).
Had it been achievable to have the F.E.2b to come sooner into action, it really is debatable that the Fokker Eindecker fighters wouldn’t have gained the supremacy that they performed.
The initial F.E.2a (No.2864) had been most likely developed in the summer of 1914; a first order of 12 were requested from the Royal Aircraft Factory, the pioneer flying on 26 January 1915.
A 2-seat pusher, this plane was operated by a 100 h.p. Green powerplant, in order to improve production and maintenance got similar outer wing parts to the B.E.2c.
The Green powerplant turned out unsatisfactory, and all planes were subsequently transformed to receive the 120 h.p. Beardmore, initial flying using this powerplant on 16 March 1915.
First production aircraft were finish in May, arriving in France afterwards that month with No.6 Squadron Royal Flying Corps. Armament was made up of a forward-firing 0.303-inch Lewis machine-gun, on a portable installation in the front cockpit.
Manufacture of the F.E.2b, an improved and fairly uncomplicated model, started in the autumn of 1915, and these planes became operational at around the turn of 1915-16.
During the entire spring and summer of 1916 the F.E.2b flew and battled effectively, subsequent planes enjoying 160 h.p. Beardmore powerplant.
By the autumn they were outclassed as fighters by the new German Albatros single-seat fighters, and in November No. 18 Squadron introduced the F.E.2b to a different purpose; night bombing. For this it took 1 x 230 lb or 3 x 112 lb bombs.
Additional F.E.2b squadrons thereafter converted to the bombing duty, as well as new squadrons were also created with the objective, the initial being No. 100, which started bombing strikes in March 1917.
The model continued to be in action with Royal Flying Corps on the Western Front ’till the end of World War One , outfitting 16 squadrons and one flight.
5 Home Defence units had F.E.2bs, however its inadequate ceiling and rate of climb made it somewhat worthless as a night fighter.
A handful of F.E.2bs were utilised for ground strafing, using a 1-pounder Vickers gun instead of the front Lewis.
In 1916 the Factory modified a pair of F.E.2bs into F.E.2cs, one of these finding the crew positions reversed to assist in night landings. This model wasn’t produced, but the F.E.2c certification was used in 1918 to a few night bomber F.E.2bs having an identical crew layout.
From spring 1916 the operating F.E.2bs were accompanied by the superior F.E.2d in which a 250 h.p. Rolls-Royce Eagle powerplant increased the speed to 94 m.p.h.
Public statistics suggest that one 1,939 F.E.2bs were assembled, but identified serial allocations just make up 1,480 of these. The F.E.2b was subcontracted to no less than 5 additional companies, main contributors being Boulton&Paul and G and J Weir.
300 F.E.2ds had been requested from Boulton&Paul, along with an additional 85 were produced by the Royal Aircraft Factory.
