Sopwith F.1 Camel / 2F.1 Camel / T.F.1

F.1 Camel

The first prototype flew in December 1916 powered by a 130 hp Clerget, and two main versions were produced by a variety of contractors, the F1 and the 2F1 shipboard variant, both powered by no fewer than six different rotary engines at various stages.

Subcontractors included:
Boulton & Paul

Boulton & Paul built F6314

Its handling characteristics were a gift to the skilful pilot but could kill the slow or unwary. This made the Camel ideal for daylight combat but versatile enough to allow it to be used as a night fighter and ground attack aircraft. The shipboard 2F1 Camel (340 built) also saw some success operating against German airships and seaplanes over the North Sea.

The Camel was flown from a lighter towed behind a fast destroyer.

Within an hour of making this successful take off on 11 August 1918 Lt. S.D. Culley shot down Zeppelin L.53 in flames off Ameland.

By the Armistice the Camel equipped 32 RAF Squadrons.

A single bay biplane, the two spar wooden wings are fabric covered. The wooden fuselage has metal covering forward of the bottom wings, plywood covering to just aft of the cockpit and fabric covering on the rear fuselage. Ailerons are on all four wings.

On naval Camel 2F.1’s the rear fuselage was detachable to save stowage space.

The shipboard 2F1 Camel also saw some success operating against German airships and seaplanes over the North Sea.

The Camel entered service in July 1917 with 4 Squadron RNAS and soon after with 70 Squadron RFC. Their first Camel victory was scored by New Zealander Clive Collett on July 27 1917. The Camel equipped the Australian 4 AFC until just before the Armistice. Capt A.H. Cobby was the highest scoring AFC pilot, gaining 29 victories while flying Camels.

Camels remained in first-line use until the Armistice. The Camel saw extensive service in home defence, over the Western front, in the UK on training and test work until 1923 and in other countries up until 1928. As well as the RFC and RNAS (later RAF) the aircraft was also operated during WWI by French and US squadrons.

The Camel is remembered as the most successful British single-seat fighter of World War I and is credited with 1,294 ‘kills’. Total Camel production was 5,490, serving also with Belgian and AEF squadrons and with other air forces. It was a Camel that shot down the German ace Rittmeister Manfred von Richthofen (the ‘Red Baron’) at the hands of Captain Roy Brown of No.209 Squadron, RAF, over Sailly-le-Sec on 21 April 1918.

Camels were built in two main versions, the F.1 for the RFC and the 2F.1 for the RNAS with detachable rear fuselage, to save stowage space on board ship, a one foot shorter span and armament of one Vickers and one Lewis gun. Engines fitted as an alternative to the 130 hp Clerget included the 110 hp Clerget, 110 hp Le Rhone and 150 hp B.R.l. The armament was also varied sometimes. Home Defence Camels had two Lewis guns mounted on the wing centre section. The T.F.1 trench strafer had two Lewis guns firing through the floor of the cockpit. Four 25 1b. bombs could be carried. Experimental versions were used for everything from dive bombing to training, as two seaters, and for experiments in using airships as flying aircraft carriers. One Camel was built with tapered wings.

An F.1 Camel was built in 1977 by Viv Bellamy at Lands End, as a flyable reproduction for Leisure Sport Ltd. It was painted to represent B7270 of 209 Squadron, RAF, the machine which Captain Roy Brown flew when officially credited with shooting down Baron Manfred von Richthofen, it has a Clerget rotary engine of 1916 and was registered as G-BFCZ until 2003. First displayed at the Brooklands museum in Weybridge, Surrey, in January 1988 for Sir Thomas Sopwith’s 100th birthday celebrations, it was purchased by the museum later that year.

A Camel was completed in 1992 with a 160 hp Gnome Monosoupape model 9N rotary at the Old Rhinebeck Aerodrome in Red Hook, New York as B6299. Built by Nathaniel deFlavia and Cole Palen. It replaced one of the Dick Day-built and -flown Camel reproductions formerly flown at Old Rhinebeck by Mr. Day in their weekend vintage airshows, which had left the Aerodrome’s collection some years earlier.

Dick Day built an airworthy F.1 at the Cavanaugh Flight Museum in Addison, Texas. It was by original factory drawings. The aircraft is fitted with original instruments, machine guns and an original Gnome rotary engine. It is painted in the scheme of the World War I flying ace Captain Arthur Roy Brown (RAF officer), a Canadian who flew with the Royal Air Force.

Dick Day also constructed an airworthy replica F.1 for the Javier Arango Collection in Paso Robles, California. It powered by a 160 hp Gnome Monosoupape 9N rotary, and registered as N8343.

Rolland Carlson in Wi, Canada, built an F.1 from Replicraft plans. Airworthy in Oliver BC Canada, it was operated as C-FGHT by the Royal Flying Corps School of Aerial Fighting Ltd, powered by a Warner Super Scarab 165 hp engine.

A full-scale replica fitted with a 119 kw (160 hp) Gnome rotary engine was built by Gerald Hampshire in Illinois in the USA where it was registered as N4463 in May 1985, eventually being registered ZK-JMU (c/n 11-11-18) in New Zealand on 26 March 2001.

C.J.Warrilow of High Wycombe, UK, was working on a Pup replica with the registration G-AVPA c/n CJW-1, in 1967.

Sopwith Snail

In October 1917, the A.B.C. Wasp seven-cylinder radial air-cooled engine was considered to offer much promise, and on the 31st of that month Sopwith was invited by the Air Board to tender designs for a single-seat fighter utilising that power plant. Four prototypes were ordered, these being of conventional construction, and, on 23 November, the company was asked to build two additional prototypes with plywood monocoque fuselages. In view of its intended function adoption of the name Snail for the new single-seater was bizarre, this being approved on 16 February 1918.

Powered by a 170hp Wasp I, the first prototype Snail was completed in April 1918, this having negative wing stagger and fabric skinning for its circular-section fuselage. Intended armament comprised two synchronised 7.7mm machine guns, a third weapon of similar calibre being mounted above the wing centre section, to starboard of the cut-out. The remaining three prototypes of conventional construction were not completed, the next Snail to fly being the first of the two with plywood monocoque fuselages and positive wing stagger. On 9 May, the monocoque Snail was sent to Martlesham Heath for official trials, the reports being less than complimentary about its manoeuvrability and low-speed control. When, in October 1918, it was decided to abandon the Wasp engine, further work on the Snail was terminated, the second monocoque prototype being discontinued before completion.

Sopwith T.F.2 Salamander

A requirement for an armoured single-seat ground attack fighter was issued to the Sopwith company in January 1918, a standard F.1 Camel being rapidly fitted with armour protection in which armour plate formed the cockpit walls, and triple-gun armament.
Flying as the T.F.1 in the following month (T.F. indicating Trench Fighter), the T.F.1 was a stop-gap type that could be made available rapidly by modifying existing aircraft, but the requirement had specified the use of a 230hp Bentley B.R.2 nine-cylinder rotary engine and Sopwith discarded the T.F.1 in favour of a modified Snipe design as the T.F.2 Salamander. Despite many similarities to the Snipe, the Salamander differed extensively and there was little or no interchangeability between the two aircraft. The forward portion of the fuselage was a simple armoured box, the bottom being 11mm plate, the sides 6mm plate, the front – the engine backplate – 8mm plate and the rear 10-mm plate with a second 6mm plate separated by 9.50cm. Armament comprised two synchronised 7.7mm guns with provision for four 11kg bombs.

The first of three prototypes was flown on 27 April 1918, and the Salamander was ordered in large numbers (contracts were placed with the parent company, Air Navigation Co, Glendower Aircraft, National Aircraft, Palladium Autocars and Wolseley Motors), 37 being on RAF charge by 31 October. When hostilities ceased, production of the Salamander continued with a view to its use by the postwar RAF, and by mid 1919, when manufacture eventually terminated, Sopwith had delivered 334 and other contractors had contributed a further 85. However, no squadron was ever equipped with this type which was abandoned in favour of the Snipe.

Sopwith Baby

Derived from the Schneider single-seat fighter seaplane, the Baby first appeared in September 1915, and differed from its predecessor primarily in having a 110hp Clerget nine-cylinder rotary in place of the 80 hp Monosoupape Gnome, this being accommodated by a horseshoe-shaped open-fronted cowling.

As on late production Schneiders, ailerons replaced wing warping for lateral control, and armament usually consisted of a single 7.7mm machine gun synchronised to fire through the propeller, although a few Babies retained the arrangement of the Schneider with the gun attached to the centre section and firing upward to clear the propeller.

Several Babies were fitted with two 7.7mm guns side by side over the wing; one batch of Blackburn-built Babies was fitted with Ranken explosive darts as anti-airship weapons, and at least one was fitted with Le Prieur rockets, 10 of these devices being attached to the interplane bracing struts. Two 29.5kg bombs could also be carried.

1916 Sopwith built Baby N2078

The Baby was widely used by the RNAS to provide fighter aircraft for use with patrol.ships, as escorts for two-seaters and for operation from early aircraft carriers.

A total of 286 Babies was built of which 195 were produced by Blackburn at Leeds – and sometimes known as Blackburn Babies – 105 of the latter being fitted with the 130hp Clerget engine, and, of these, 40 were fitted (initially) to carry the Ranken dart and no gun armament. A more extensive modification of the Sopwith float fighter was the Fairey Hamble Baby.

Sopwith Schneider

Derived from the Tabloid float seaplane which won the Schneider Trophy contest in April 1914, the Schneider, the single-seat twin-float seaplane ordered into production in November 1914 for the RNAS resembled closely the aircraft that had gained the Trophy at Monaco. Retaining the same 100hp Gnome Monosoupape nine-cylinder rotary – the upper half of which was enclosed by a ‘bull-nose” cowling – and wing-warping lateral control, the Schneider had a larger fin and rudder, reinforced float bracing and an aperture in the centre section for an upward-angled 7.7mm machine gun.

The RNAS ordered 136 Schneider floatplanes for reconnaissance and light bombing duties, the aircraft entering service in 1915.

Used for patrol duties against enemy airships from seaplane stations around the British coast, the Schneiders were provided with incendiary ammunition and operated against Zeppelins from early 1915. Schneiders were also carried aboard light cruisers of the North Sea Patrol for anti-Zeppelin operations, and served at the Dardanelles, in the Aegean and in the Eastern Mediterranean. Two Schneiders operated from the carrier Ark Royal in April 1915 at Mudros, and the type was still serving in the Aegean as late as November 1916, one shooting down an enemy aircraft which had attacked the airship shed at Mudros on the 21st of that month.

A total of 136 Schneiders is believed to have been built, progressive development resulting in the Baby.

Sopwith Special / Type C

Type C

The Sopwith Type C and the Sopwith Special were actually two virtually identical designs built to two different contracts – the Type Cs were ordered in July 1914, whilst the ‘Special Tractor Biplane Seaplane’ was ordered first in February 1914. Despite appearing after the Special, the Three Type Cs were allocated the RNAS serials 157 to 159 and the Special received the serial number 170. The photo above shows the Sopwith Special number 170.

The Special and Type Cs were the first purpose built British aeroplanes capable of carrying a torpedo, unfortunately they were not capable of lifting said torpedo into the air! The design was generally considered a failure because of this rather embarrassing character trait. In 1914 commander of the Calshot naval air station Cmdr Arthur Longmore of the Royal Naval Air Service and other RNAS pilots carried out torpedo carrying practice with 14-inch weapons in what Longmore described as the Sopwith Canton-Unné seaplane in August 1914 during experiments at Calshot. Its name was derived from its powerplant.

Sopwith Tabloid / SS

The Sopwith Aviation Company Tabloid was originally designed as sports aircraft and was first flown by Harry Hawker on 27 November 1913. It was a two-seater single-bay biplane with a side-by-side seating configuration. It was powered by a Gnôme rotary and had warping wings for lateral control.

A single-seat Tabloid was quickly mounted on floats and entered in the 1914 Schneider Trophy in Monaco – which it handily won giving Britain her first victory in the annual contest piloted by Howard Pixton, at the same time setting a world seaplane speed record at 92 mph. It’s turn of speed so demoralised the other dozen or so entries from 6 countries that only one other even bothered to take off. The performance was so convincing that the British military ordered many of these aircraft, which was developed into the Sopwith Schneider. It therefore became the first single-seat scout anywhere to go into production for military use.

Sopwith Tabloid Article

A single-bay biplane, the two-spar wooden wings and wooden fuselage are fabric covered. Wing warping rather than ailerons was used, and conventional tail surfaces were fitted. Two skids were normally fitted forward of the wheels.

Some aircraft were fitted experimentally with a Lewis machine gun above the wing centre section or on the side of the fuselage, with steel plates on the airscrew blades to deflect bullets. A few 20 lb bombs could be carried.

The Tabloid was ordered by both the Royal Flying Corps and Royal Naval Air Service; the latter using it for some of the earliest strategic bombing attacks against Germany. Thirty-six Tabloid were delivered for the RNAS and RFC between October 1914 and June 1915. When the 1914 18 War started, Tabloids went to Belgium with a squadron of the RNAS.

The Royal Naval Air Service used their Tabloids in early bombing attacks against the airship sheds at Cologne and Dusseldorf in an attempt to deny the Germans the use of operating bases close to the North Sea. The first raid took place on 22 September 1914 and although not a success was the first ever air raid on Germany. The second raid was much more successful. In one raid F1t. Lt. R.L.G.Marix destroyed an airship shed at Dusseldorf with his 20 lb bombs, complete with the secret Zeppelin Z.1X inside.

Royal Flying Corps Tabloids were used for scouting duties and were involved in some of the earliest experiments in arming aircraft. From February 1915 a number of Tabloids were fitted with Lewis machine-guns. Although it was one of the first aircraft to have a machine gun fitted to fire through the propeller arc it was only after the Tabloid had been withdrawn from operational service in the spring of 1915 that a successful interrupter gear was developed.

Sopwith Gun Bus

The Gun Bus was essentially a landplane derivative of the S.P.Gn (Sopwith Pusher, gun. The Gun Bus, intended for the fighting role, carried a 7.7mm machine gun on a flexible mount in the forward cockpit and was powered by a 100hp Gnome Monosoupape rotary engine. A more powerful version, with a 150hp Sunbeam eight-cylinder water-cooled engine, was developed specifically for the RNAS, this having a redesigned nacelle and a revised undercarriage. Six of the Sunbeam-powered Gun Buses were built for the RNAS by Sopwith, a further 30 being ordered for the service from Robey & Company, these last being intended for bombing (and possibly anti-submarine) duties as distinct from fighting. The pilot was moved forward to the front cockpit, a bombing panel being let into the floor and four bomb carriers being fitted beneath the lower wing.
