Despite being a two-seater, the F.2B proved to be an agile aircraft that was able to hold its own against opposing single-seat fighters.
Having overcome a disastrous start to its career, the F.2B's solid design ensured that it remained in military service into the
1930s, and surplus aircraft were popular in civil aviation.

Design and development
The [Vous devez être inscrit et connecté pour voir ce lien] fighter's basic design stemmed from design studies by [Vous devez être inscrit et connecté pour voir ce lien] in March 1916 for an aircraft in the same class as the [Vous devez être inscrit et connecté pour voir ce lien] and the [Vous devez être inscrit et connecté pour voir ce lien] - the Type 9 R.2A with the 160 hp Beardmore engine and the R.2B, powered by the 150 hp Hispano Suiza.[Vous devez être inscrit et connecté pour voir ce lien]

Neither type was built as the new 190 hp (142 kW) [Vous devez être inscrit et connecté pour voir ce lien] I [Vous devez être inscrit et connecté pour voir ce lien] became available, and Barnwell designed a new aircraft around the Rolls-Royce engine.
This, the Type 12 F.2A was a more compact design, intended from the outset as a two-seat fighter: it first flew on 9 September 1916.[Vous devez être inscrit et connecté pour voir ce lien]

The F.2A was armed in what had by then become the standard manner for a British two-seater: one [Vous devez être inscrit et connecté pour voir ce lien] fixed, forward-firing .303 in (7.7 mm) [Vous devez être inscrit et connecté pour voir ce lien], and one flexible .303 in (7.7 mm) [Vous devez être inscrit et connecté pour voir ce lien] mounted on a [Vous devez être inscrit et connecté pour voir ce lien] in the observer's rear cockpit.

Only 52 F.2As were produced before production switched to what became the definitive Bristol Fighter, the Bristol Type 14 F.2B which had first flown on 25 October 1916.
The first 150 or so were powered by the Falcon I or Falcon II engine but the remainder were equipped with the 275 hp (205 kW) Falcon III engine and could reach a maximum speed of 123 mph (198 km/h).
The F.2B was over 10 mph (16 km/h) faster than the F.2A and was three minutes faster at reaching 10,000 ft (3,000 m).
A second Lewis gun was often added to the rear cockpit.

The [Vous devez être inscrit et connecté pour voir ce lien] is often described as an "all-metal version of the F.2b".
In fact it was a totally new design - although it shared the characteristic of having the fuselage positioned between the upper and lower wing.
Two prototypes were built, the first flying on 23 October 1917, but the M.R.1 never entered mass production.

Alternative engines
[Vous devez être inscrit et connecté pour voir ce lien] aero engines of all types were in chronic short supply in this period, and the Falcon was no exception.
Plans to make the Bristol Fighter the standard British two-seater, replacing the R.E.8 and F.K.8, stalled against this barrier; there simply would not have been enough Falcons available.
Efforts to find an available [Vous devez être inscrit et connecté pour voir ce lien] that was sufficiently powerful and reliable, ultimately failed.

The Type 15 was fitted with a 200 hp (150 kW) [Vous devez être inscrit et connecté pour voir ce lien] piston engine.
This motor suffered from chronic vibration and the "Arab Bristol" was never a viable combination, in spite of prolonged
development.
A few Arab-engined Bristols were at the front very late in the war – but most British reconnaissance squadrons had to soldier on with the R.E.8 and F.K.8 until the end of hostilities.

This worked better than the Arab - but the Hispano-Suiza availability was no better than for the Falcon, and the motors that were available were required for the [Vous devez être inscrit et connecté pour voir ce lien] and [Vous devez être inscrit et connecté pour voir ce lien].
The 300 hp (220 kW) version of the Hispano-Suiza, suggested for the Type 17 was not available in numbers before the end of the war.
