The Sopwith Camel was a British World War I single-seat fighter biplane, famous for its manoeuverability. Representing the state-of the-art in fighter design at the time, the compact and lightweight Camel was the most prolific of Sopwith's wartime fighters. Introduced on the Western Front in 1917, the Camel F.1 helped establish aerial superiority over German fighters, shooting down 1,294 enemy aircraft during its combat service. The combination of a short-coupled fuselage, heavy, powerful rotary engine and the concentrated fire from twin synchronized machine guns produced a deadly weapons system. The configuration created a tight torque effect turning ability that was mastered by some pilots but also led to a reputation as a difficult aircraft to fly, with its highly sensitive controls leading to the deaths of many student pilots.[1]
Design and development
Intended as a replacement for the Sopwith Pup,[2] the Camel prototype first flew in December 1916, powered by a 110 hp Clerget 9Z. Known as the "Big Pup" early on in its development, the aircraft was armed with two .303 in (7.7 mm) Vickers machine guns mounted in the cowl, firing forward through the propeller disc. A fairing surrounding the gun installation created a "hump" that led to the name Camel.[2] The bottom wing had dihedral but not the top, so that the gap between the wings was less at the tips than at the roots. Approximately 5,490 units were ultimately produced.[3]

The type entered squadron service in June 1917 with No. 4 Squadron of the Royal Naval Air Service, near Dunkirk. The following month, it became operational with No. 70 Squadron of the Royal Flying Corps. By February 1918, 13 squadrons were fully equipped with the Camel.
Unlike the preceding Pup and Triplane, the Camel was not considered pleasant to fly. The Camel owed both its extreme manoeuvrability and its difficult handling characteristics to the grouping of the engine, pilot, guns, and fuel tank within the first seven feet of the aircraft, coupled with the strong gyroscopic effect of the rotary engine.
The Camel soon gained an unfortunate reputation with student pilots. The Clerget engine was particularly sensitive to fuel mixture control, and incorrect settings often caused the engine to choke and cut out during takeoff. Many crashed due to mishandling on takeoff when a full fuel tank affected the center of gravity. In level flight, the Camel was markedly tail-heavy. Unlike the Triplane, the Camel lacked a variable incidence tailplane, so that the pilot had to apply constant forward pressure on the control stick to maintain a level attitude at low altitude. However the machine could also be rigged in such a way that at higher altitudes it could be flown "hands off." A stall immediately resulted in a spin and the Camel was particularly noted for its vicious spinning characteristics.
The Camel was, however, a superlative fighter, and offered heavier armament and better performance than the Pup and Triplane. In the hands of an experienced pilot, its manoeuvrability was unmatched by any contemporary type. Its controls were light and sensitive. The Camel turned rather slowly to the left which resulted in a nose up attitude due to the torque of the rotary engine. But the engine torque also resulted in its most famous quality, the ability to turn to the right in half the time of other fighters,[4] although that resulted in more of a tendency towards a nose down attitude from the turn. Because of the faster turning capability to the right, to change heading 90° to the left, many pilots preferred to do it by turning 270° to the right. Because it was tail heavy, the plane also looped quickly. Agility in combat made the Camel one of the best-remembered Allied aircraft of the First World War. It was said to offer a choice between a "wooden cross, red cross and Victoria Cross." Together with the S.E.5a, the Camel helped to wrest aerial superiority away from the German Albatros fighters. The Camel was credited with shooting down 1,294 enemy aircraft, more than any other Allied fighter.
Major William Barker's Sopwith Camel (serial no. B6313, the aircraft in which the majority of his victories were scored,[5]) became the most successful fighter aircraft in the history of the RAF, shooting down 46 aircraft and balloons from September 1917 to September 1918 in 404 operational hours flying. It was dismantled in October 1918. Barker kept the clock as a memento, but was asked to return it the following day.
By mid-1918 the Camel was becoming obsolescent as a fighter, limited by its slow speed and comparatively poor performance at altitudes over 12,000 ft (3,650 m). It found a new lease of life as a ground-attack and infantry support aircraft. During the German offensive of March 1918, flights of Camels harassed the advancing German Army, inflicting high losses (and suffering high losses in turn) through the dropping of 25lb (11 kg) Cooper bombs and ultra-low-level strafing. The protracted development of the Camel's replacement, the Sopwith Snipe, meant that the Camel remained in service until the Armistice.
In summer 1918 a 2F.1 Camel (N6814) was used in trials as a parasite fighter under Airship R23
Variants
The Camel was powered by a variety of rotary engines during the production period.
- 130 hp Clerget 9B Rotary (standard powerplant)
- 140 hp Clerget 9Bf Rotary
- 110 hp Le Rhone 9J Rotary
- 150 hp Bentley BR1 rotary (gave best performance - standard for R.N.A.S. machines)
- 100 hp Gnome Monosoupape 9B-2 Rotary
- 150 hp Gnome Monosoupape 9N Rotary
Engine variants
- With rotary engines, the crankshaft remained fixed while the cylinders and attached propeller rotated around it. The result of this torque was a significant "pull" to the right. In the hands of an experienced pilot, this characteristic could be exploited to give exceptional manoeuvrability in a dogfight. A 3/4 turn to the right could be done in the same time as a 1/4 turn to the left.
- The Gnome "mono" engines did not have throttles and were at full "throttle" while the ignition was on - they could be "throttled" with a selector switch which cut the ignition to some of the cylinders to reduce power for landing. The Clerget, Le Rhone and BR1 had throttles, although reducing power involved simultaneously adjusting the mixture and was not straightforward, so it became common during landing to "blip" the engine (turn the ignition off and on) using a control column-mounted ignition switch, the blip switch, to reduce power.
Sopwith Camel F.1
- Single-seat fighter ("scout") aircraft.
- The main production version. Armed with twin synchronised Vickers guns.
Sopwith Camel 2F.1
- Shipboard fighter scout aircraft.
- Slightly shorter wingspan
- One Vickers gun replaced by an overwing Lewis gun
- Bentley BR1 as standard engine
Sopwith Camel "Comic" Night fighter
Pilot seat moved to rear. The twin Vickers guns were replaced with two Lewis guns firing forward over the top wing on Foster mountings. Served with Home Defence Squadrons against German air raids. The "Comic" nickname was of course unofficial, and was shared with the night fighter version of the Sopwith 1½ Strutter.
F.1/1
- Version with tapered wings.
(Trench Fighter) T.F.1
- Experimental trench fighter.
- Downward angled machine guns
- Armour plating for protection

Replicas
- A replica Sopwith F.1 Camel is on display at the National Museum of the United States Air Force in Dayton, Ohio. This aircraft was built by Air Force Museum personnel from original WWI factory drawings and was completed in 1974. It is painted and marked as the Camel flown by Lt. George A. Vaughn Jr. while flying with the 17th Aero Squadron.[11]
- A replica is currently under construction by the Northern Aeroplane Workshops for the Shuttleworth Collection[12], and another is under construction at the Great War Flying Museum.
- In 1969 Slingsby built a flyable Type T.57 Sopwith Camel Replica powered by a 145hp Warner Scarab engine for use in a Biggles film. This aircraft is now on display at the Fleet Air Arm Museum, Yeovilton painted as B6401.[13][14]
- Old Rhinebeck Aerodrome flies a reproduction that was completed in 1992 with a Le Rhone rotary.

The Camel appears in literature and popular media as:
- The single-seater scout plane flown by the Royal Flying Corps Squadron in the semi-autobiographical, First World War air combat book Winged Victory written by Victor Maslin Yeates.
- The fighter flown by Biggles in the novels by W.E. Johns during the character's spell in 266 squadron during the First World War. He also wrote a book, The Camels Are Coming.
- The "plane" of Snoopy in the Peanuts comic strip, when he imagines himself as a First World War flying ace and the nemesis of the Red Baron. The Red Baron frequently shoots him down, and in fact, Snoopy was forced to wash dishes once for "losing too many Sopwith Camels". The "Sopwith Camel" is actually his doghouse. The Camel's dedicated mechanic was none other than Woodstock, and the ground crew was Snoopy's bird friends. (When Marcie asked Snoopy "midflight" why his plane was so clean, Snoopy replied, "I have a dedicated mechanic." The punch line was that Woodstock sprayed Marcie with a hose just at that moment.)
- The type of aircraft flown in the First World War by John and Bayard Sartoris in William Faulkner's Flags in the Dust. Under fire from a pupil of Richthofen (the Red Baron), John's Camel caught fire over occupied France. Bayard's last sight of his twin brother was of John jumping out of his fighter feet first. Faulkner also wrote about the Camel (and Sartoris) in his famous story All the Dead Pilots.
- Bartholomew Bandy flies a Camel in the first "Bandy Papers" book by Donald Jack, Three Cheers for Me.
