The Sopwith Camel was a British First World War single-seat biplane fighter aircraft introduced on the Western Front in 1917. It was developed by the Sopwith Aviation Company as a successor to the earlier Sopwith Pup and became one of the most iconic fighter aircraft of the First World War. It was powered by a single rotary engine and was armed with twin synchronised machine guns.
The type was highly manoeuvrable and popular with its pilots although the combination of the short-coupled aircraft and the rotary engine produced some handling quirks that could catch out inexperienced pilots. The Camel proved to be very successful in aerial dogfights and is said to have achieved more victories in combat than any other single type during the First World War. Though proving difficult to handle, it provided for a high level of manoeuvrability to an experienced pilot, an attribute which was highly valued in the type's principal use as a fighter aircraft. In total, Camel pilots have been credited with the shooting down of 1,294 enemy aircraft, more than any other Allied fighter of the conflict.
The first aircraft was cleared for flight at Brooklands on 22nd December 1916 and flown then, or shortly thereafter. It was utilised extensively by both the Royal Flying Corps (RFC) and the Royal Naval Air Service (RNAS) after it entered service from mid-1917.
The prototype Camel 2F.1 (with a 150 hp Bentley rotary engine) first flew in March 1917 and carried the Serial N5 and it was this variant that was mainly used for naval service. The 2.F1 variant can be distinguished by its use of slim steel centre-section struts, replacing the wooden struts of the F.1 Camel.
Towards the end of the Great War, the type had also seen use as a ground-attack aircraft, partially due to it having become increasingly outclassed as the capabilities of fighter aircraft on both sides were rapidly advancing at that time.
The Camel also saw use as a two-seat trainer aircraft. In January 1920, the last aircraft of the type were withdrawn from RAF service.
Sopwith Camel F.1
The F.1 was the main production version. It was armed with twin synchronised Vickers guns.
Sopwith Camel 2F.1
The 2F.1 was a shipboard variant, flown from HMS Furious. It had a slightly shorter wingspan and a Bentley BR1 as its standard engine. Additionally, one Vickers gun was replaced by an overwing Lewis gun.
Sopwith Camel "Comic" Night fighter
The "Comic" was a Camel variant designed specifically for night-fighting duties. The twin Vickers guns were replaced by two Lewis guns on Foster mountings firing forward over the top wing, as the muzzle flash of the Vickers guns could blind the pilot. To allow reloading of the guns, the pilot was moved about 12 inches (30 cm) to the rear and to compensate the fuel tank was moved forward. It served with Home Defence Squadrons against German air raids. The "Comic" nickname was unofficial, and was shared with the night fighter version of the Sopwith 1½ Strutter.
F.1/1
The F1/1 was a version with tapered wings.
T.F.1
The T.F.1 was an experimental trench fighter used for development work for the Sopwith Salamander. Its machine guns were angled downwards for efficient strafing, and it featured armour plating for protection.
Trainer
The trainer variant had a second cockpit behind the normal pilot's position. The weapons were removed, although the hump was sometimes kept.
Camels were powered by several rotary engines:
130 hp Clerget 9B rotary (standard powerplant)
140 hp Clerget 9Bf rotary
110 hp Le Rhône 9J rotary
150 hp Bentley BR1 rotary (gave best performance – standard for R.N.A.S. machines)
100 hp Gnome Monosoupape 9B-2 rotary
160 hp Gnome Monosoupape 9N rotary
