Sharing little more than its configuration with the F.E.2
flown at Farnborough in 1913, the F.E.2a appeared early
in 1915 and was designed to provide the RFC with an
armed reconnaissance aircraft. It was a large three-bay
biplane, using a flat centre section and outer panels
that were identical with those of the B.E.2c,
and incorporating dihedral. A short nacelle carried the
observer/gunner in the nose ahead of the pilot, and the
pusher engine. The tail unit was carried by four booms
extending aft from the wings and comprised a large
tailplane with elevators, a kidney-shaped rudder and
small triangular fin above the tailplane. A small nosewheel
was provided ahead of the oleo-strutted main
wheels to help prevent nosing over, and the whole of
the upper wing centre section trailing-edge aft of the
rear spar was hinged for use as a flap-cum-airbrake.
Armament normally comprised a 7.7mm
Lewis machine gun in the front cockpit on one of
several alternative mounts. The first F.E.2a flew on 26
January 1915 with a 100hp Green six-cylinder inline
water-cooled engine but proved underpowered and the 120hp Austro-Daimler built under licence by Beardmore
became the standard for 11 more F.E.2a's and
early production examples of the F.E.2b. The latter was
the "productionised" version with the Beardmore
engine, trailing-edge flap deleted, simplified fuel
system and other changes to facilitate large-scale production
by inexperienced companies. These comprised,
apart from the RAF itself (which built only 47
F.E.2b's): Boulton & Paul (250); Barclay Curie (100);
Garrett & Sons (60); Ransome, Sims & Jefferies (350);
Alex Stephen and Sons (150) and G & J Weir (600). A
160hp Beardmore engine was adopted later, and the
oleo u/c with nose wheel gave way to a simplified form
without the nosewheel or, later, a non-oleo V-strut arrangement. All 12 F.E.2a's and almost a thousand
F.E.2b's went to RFC squadrons in France, where they
engaged in offensive patrols over the enemy lines in
the role of fighter escort for unarmed reconnaissance aircraft. Over 200 were issued to Home Defence units,
some of these flying as single-seaters, and service use
of the F.E.2b continued until the Armistice in November
1918.
