The first attempt by Westland to develop a monoplane fighter evolved from a private venture prototype designed – by the company’s draughtsmen in their spare time – during 1926 with high speed performance the primary objective. Known simply as the Racer, this unarmed parasol monoplane of mixed construction was powered by a 275hp Rolls Royce Falcon III inline engine and flew in November 1926. Badly damaged in a forced landing in 1927, the Racer was rebuilt in much modified form as the Wizard fighter. In this form, it was primarily of metal construction and had a 490hp unsupercharged Rolls-Royce F.XI 12-cylinder Vee-type water:cooled engine in a more streamlined nose cowling, with a retractable radiator in the underside of the fuselage. The Wizard – which was flying by late 1927 – used a similar parasol wing to that of the Racer, this being mounted close to the fuselage on tandem pylons on the fuselage centreline. Two 7.7mm Vickers guns were mounted semi-externally in the fuselage sides. The Wizard’s performance, and particularly its rate of climb, attracted a modicum of Air Ministry interest and a contract to cover testing at Martlesham Heath. There, the pilot’s forward view was found unsatisfactory, leading Westland to design and fit a new wing with changed planform outboard, new inset ailerons and a thinner centre section, mounted on more conventional cabane strutting. A supercharged 500hp Kestrel II (F.XIS) was fitted, but in this final form, the Wizard II, as it was sometimes known, demonstrated a reduced performance and failed to persuade the Air Ministry to change its policy towards monoplane fighters.

The Yeovil day-bomber biplane design was commenced by Westland in 1923. The Yeovil was the first of the Westland post-war military designs, to an Air Ministry Specification, and was built specially to accommodate the biggest engine then available, the newly developed 650hp Rolls Royce Condor engine. Three machines in all were produced, numbered J.7508, J.7509 and J.7510, the first slightly differing from the others in undercarriage arrangement and the fairing of the wing tanks. The prototype was initially test-flown at Andover, in the summer of 1925, by Captain Frank Courtney, the development testing of the subsequent machines being in the hands of Major L. P. Openshaw.
Several other firms built prototypes to the same Specification and, although the Yeovil did not go into production the three examples built were used for research work.

The Woodpigeon biplane was first conceived as the Westland entry in the Air Ministry’s Light Aeroplane Competition of 1924, but was finally produced with the main object of being tested side-by-side with another Westland competitor, the Widgeon high-wing monoplane, in order to weigh the relative merits of a biplane and a monoplane with almost identical wing areas and power loadings. In the Competition and in later trials at Westland it soon became obvious that the Widgeon monoplane was much superior although, on paper, each machine should have had identical performances. In their endeavour to make a fair assessment the Westland technicians insisted on cutting a runway, with a hand-mower, through the long grass of Yeovil aerodrome, in order to get the Woodpigeon airborne. In fact it was so difficult to keep the little aeroplane in the air that it was decided to decrease the wing loading, so a second Woodpigeon, G-EBJV, was built with a large span, and the wings of the original machine, G-EBIY, were also increased to suit. Further tests in this form, and with the more powerful Anzani engine, were carried out by Major L. P. Openshaw, and in the end the Woodpigeons were flying reasonably enough to attract the interest of two private owners.

The years following the conclusion of the First World War were notable for an official lack of attention to the needs of the fighting services. The Westland design staff was asked to produce, in 1920, a carrier-borne fleet reconnaissance biplane for the Royal Navy.
The machine required had to be, basically a D.H.9A, but was to have a 450hp Napier Lion engine in place of the 400hp Liberty motor, and to be equipped with the various items of gear as a naval aircraft.
Westland Aircraft produced thirty-six aircraft of the type demanded. The machine, which was given the name of Walrus, carried a crew of three. The pilot’s cockpit was situated immediately aft of the wing trailing edge, with a Scarff-mounted Lewis gun over the cockpit behind him. The floor of the rear fuselage was fitted with a glazed observation blister, for use in the prone position, while a radio transmitter – operated by the observer – was situated in a third cockpit, aft of the rear gunner’s position.
Features of the machine included rubber flotation bags, which could be inflated from compressed air bottles, a patent jettison valve on the main fuel tank, which allowed the petrol to be discharged in a few seconds and then, if the machine alighted on the sea, would automatically re-seal the tank into an additional flotation chamber. The aircraft had folding wings. Another special feature was the undercarriage, capable of being dropped by the pilot in the event of an emergency and fitted with a set of jaws for gripping the carrier’s deck arresting-wires. These wires ran along the length of the flight-deck and not across the beam of the ship.
The prototype Walrus, and the subsequent production machines, were flight-tested by Captain A. S. Keep, M.C., who reported the aircraft as being somewhat vicious in its behaviour. In Service use the Walrus did not shine and the type was not produced beyond the original contract number – which in those days was regarded as a big order.
