The Gloster TSR.38 was a single-engined three-seat biplane designed as a naval torpedo/spotter/reconnaissance aircraft in the early 1930s. It did not reach production and only one was built.
Gloster built what was at first known as the FS.36 (FS standing for fleet spotter) to Air Ministry specification S.9/30 which called for a three-seat torpedo bomber/spotter/reconnaissance aircraft, starting work in late 1930 but proceeding slowly so it did not fly until early April 1932. This aircraft, powered by a 600 hp (450 kW) Rolls-Royce Kestrel IIMS engine was flown to RAF Martlesham Heath for initial testing. RAF pilots reported good handling at higher speeds but criticised its low speed handling and braking, important parameters for a carrier landing aircraft. It then returned to Gloster's for modification, partly to meet these criticisms and partly to cover a new specification S.15/33, a melding of the early specification with M.1/30. Re-engined with a Rolls-Royce Goshawk VIII of 690 hp (515 kW), and with modified wings of greater area the aircraft emerged in mid-1933 as the TSR.38, TSR standing for torpedo/spotter/reconnaissance. [1]
The TSR.38 was a fabric covered all metal machine with steel sparred wings with duralumin and steel ribs. It was a single bay biplane with staggered wings of almost equal span and sharp, 10° sweepback. The airfoils were thick, the lower thicker and the upper wings carried leading edge automatic slots for low speed control. The wings could be folded from the centre section for carrier stowage. The lower wing centre section had anhedral to allow a shorter undercarriage and also carried a pair of underwing radiators. The undercarriage was of the fixed, split axle type required for torpedo launches, with torpedo crutches between the legs and there was a small, spatted tailwheel. For carrier landing there was a hinged arrestor hook ending just in front of the tailwheel. The three crew sat in separate open cockpits, the pilot in front under a cut-out in the upper wing trailing edge, his navigator behind him and furthest aft the gunner with a Lewis gun on a Scarff ring. The fin was large and rounded with a generous rudder, a little like that of the later Gladiator, with the tailplane braced from above to the fin. [1]
After flight trials at Gloster's the TSR.38 went to RAF Gosport where it made dummy carrier landing before joining HMS Courageous in August 1934 for real naval tests. It then returned to Martlesham for a thorough evaluation. However, its rather dilatory development now caught up with it in the form of a superior, later private venture from Fairey, which was to become the famous Fairey Swordfish and further work on the TSR.38 was ended.

A design for pure reconnaissance variant was submitted to the Royal Australian Navy in 1931 but was not successful. [2]

The Hawker Hart is a British two-seater biplane light bomber aircraft that saw service with the Royal Air Force (RAF). It was designed during the 1920s by Sydney Camm and manufactured by Hawker Aircraft. The Hart was a prominent British aircraft in the inter-war period, but was obsolete and already side-lined for newer monoplane aircraft designs by the start of the Second World War, playing only minor roles in the conflict before being retired.
The Fairey Aviation Company Fairey III was a family of British reconnaissance biplanes that enjoyed a very long production and service history in both landplane and seaplane variants. First flying on 14 September 1917, examples were still in use during the Second World War.
The Hawker Nimrod is a British carrier-based single-engine, single-seat biplane fighter aircraft built in the early 1930s by Hawker Aircraft.
The Fairey Campania was a British ship-borne, patrol and reconnaissance aircraft of the First World War and Russian Civil War. It was a single-engine, two-seat biplane with twin main floats and backward-folding wings. The Campania was the first aeroplane ever designed specifically for carrier operations.
The Hawker P.V.3 was a British single-engined biplane fighter prototype of the 1930s. Only a single example was built, the Gloster Gladiator being selected instead to fulfill the requirement to which it was designed.
The Supermarine Type 224 was an inverted gull-wing monoplane fighter aircraft designed by R.J. Mitchell at Supermarine in response to Air Ministry Specification F.7/30, which sought a fighter for introduction to succeed the Gloster Gauntlet. It was powered by the Rolls-Royce Goshawk engine, which used an experimental evaporative cooling system, and problems with this system, combined with its disappointing performance, led to it being rejected, a contract for production aircraft eventually going to the Gloster Gladiator. It is nevertheless notable because R.J. Mitchell learnt lessons from its failure that were to contribute greatly to his success with the Supermarine Spitfire.
The Supermarine Type 322 was a prototype British carrier-borne torpedo, dive bomber and reconnaissance aircraft of the Second World War. A single-engined monoplane, it was unsuccessful, with only two examples being built. The Fairey Barracuda, built to the same specification, would fill this role.
The Blackburn T.R.1 Sprat was a British single-engine two-seat biplane trainer, built in 1926 for advanced training, deck-landing and seaplane experience. Just one was built.
The Blackburn 2F.1 Nautilus was a British single-engine two-seat biplane spotter/fighter built in 1929. Only one was completed.
The Blackburn B.T.1 Beagle was a British single-engine, two-seat biplane bomber/torpedo aircraft from 1928. Designed to Air Ministry specifications which led to no contracts for any manufacturer, only one Beagle was built.
The Gloster Goring was a single-engined two-seat biplane designed to meet 1926 Air Ministry specifications for a day/torpedo bomber. It was not put into production and the one aircraft built served later as an engine testbed.
The Gloster TC.33 was a large four-engined biplane designed for troop carrying and medical evacuation in the early 1930s. Only one was built.
The Fairey Fleetwing was a British two-seat, single-engine biplane designed to an Air Ministry contract for carrier-based reconnaissance operations in the late 1920s. Only one was built.
The Bristol Type 133 was a single-seat, single-engine monoplane fighter armed with four guns, using stressed-skin construction and with a retractable undercarriage. It was built by The Bristol Aeroplane Co. to meet Specification F.7/30. The single example crashed before the trials commenced.
The Vickers Type 207 was a single-engined two-seat biplane designed as a shipborne torpedo bomber to an early 1930s specification. Structurally innovative, only one was built.
The Fairey G.4/31 was a British single-engined, two-seat biplane contender for an Air Ministry specification for a multi-role or general purpose aircraft. Unsuccessful, only one was built.
The Fairey S.9/30 was a two-seat, single-engined biplane built to meet an Air Ministry specification for a fleet reconnaissance aircraft. It flew during 1934-6 in both land- and seaplane configurations. Although only one was built, it was the progenitor of the Fairey Swordfish.
The Handley Page Type S, or HPS-1 was a prototype British carrier-based fighter developed for the United States Navy in the early 1920s. A low-wing monoplane, it was unsuccessful, only two being built and flown.
The Westland F.7/30 was a British fighter prototype. A single prototype was built in 1934, but the type was not put in production because its performance fell far below the RAF's requirements. The Gloster Gladiator won the F.7/30 competition.
The Short Gurnard was a single-engined two-seat biplane naval fighter, built in the United Kingdom to an Air Ministry specification in 1929. It failed to win production orders and only two flew.
