History
The firm had been formed in 1937 as a subsidiary of the British American Tobacco Company at Eastleigh, near Southampton, to build the Burnelli Flying Wing aircraft under licence, and was renamed Cunliffe-Owen Aircraft Limited in May 1938 by Hugo Cunliffe-Owen having been formed as B.A.O., Ltd. (Aircraft manufacturers and dealers, of Hangar No. 2a, Southampton Airport). The nominal capital was increased by the addition of £49,900 beyond the registered capital of £100. The additional capital was divided into 39,900 ordinary and 10,000 5 per cent, non-cumulative preference shares of £1 each. The organisation was registered as a 'private' company on 9 September 1937. By a board resolution dated 11 May 1938, the name was changed to "Cunliffe-Owen Aircraft, Ltd."
The factory, purposefully located on a 44-acre (180,000 m2) site near to Southampton Airport, was built as a shadow factory in preparation for World War II, and was opened by the Mayor of Southampton on 2 February 1939. [4]
The company intended to produce the Burnelli UB-14 lifting fuselage under licence as the Cunliffe-Owen OA-Mk1. An example was assembled in 1939. The resulting plane was known as the Clyde Clipper but only one [5] had been completed before the start of the war. The sole aircraft was pressed into service by the RAF and was eventually turned over to the Free French Air Force in Africa, [6] where at one point it served as the personal transport of General Charles de Gaulle. Worn out by its wartime service, the Clyde Clipper reportedly met its end as the centrepiece of a V-J Day (Victory over Japan Day) bonfire. [7]
WW2
On the outbreak of WWII, all of the factory's capacity was switched to produce parts for the Supermarine Spitfire. Recognised as an important part of the British war effort, it was bombed on a number of occasions by the German Luftwaffe , the first in September 1940.

The company's design officer tendered ideas for Air Ministry specifications: an un-numbered ground attack specification in 1942, [8] specification O.5/43 [9] and specification S.6/43 for a shore based torpedo bomber. [10]
The company also undertook repair and overhaul work for Supermarine, whose test facilities were located on the same airfield. In 1940 they were selected to be one of the factories producing the Hawker Tornado, but that project was cancelled in 1941. In 1943 they won a contract to produce the Supermarine Seafire, 118 Seafire Ibs incorporating the fuselage reinforcements were modified from Spitfire Vbs by the company and Air Service Training. These aircraft were equipped with naval high frequency radio equipment and IFF equipment as well as a Type 72 homing beacon. In these and all subsequent Seafires the instruments were re-calibrated to read knots and nautical miles rather than miles per hour. The fixed armament was the same as that of the Spitfire Vb; two 20 mm Hispano Mk II cannon with 60 rounds per gun fed from a "drum" magazine, and four .303 inch.303 British Browning machine guns with 350 rpg. Provision was also made to carry a 30-gallon "slipper" fuel tank under the fuselage. One frontline unit, 801 Squadron Royal Naval Air Service operated this version on board HMS Furious from October 1942 through to September 1944. Production continued until 1946. Cunliffe-Owen Aircraft Limited also had a factory on the Macmerry aerodrome [11] near Edinburgh, Scotland the workforce of which were principally concerned with the repair of Lockheed Hudson aircraft.
Post war era
After the war they produced their first, and only, indigenous design, the Cunliffe-Owen Concordia, a 12-seat feederliner design. The Concordia project was abandoned in 1947 and the two prototypes were scrapped. Given the low use of the factory during this period, they sublet portions of the plant to the Cierva Autogiro Company starting in 1946 with Cunliffe-Owen undertaking production of Cierva's designs. When it first flew in 1948 the Cierva W.11 "Air Horse" was the largest helicopter in the world. It was powered by a Rolls-Royce Merlin 24 engine driving three main rotors mounted on large outriggers, one at the front and two either side of the fuselage just aft of its midpoint. There were two large fins at the rear of the fuselage, and a cockpit on top of the nose which housed a crew of three. It had a passenger carrying capacity of 24. It was envisaged to fulfil roles as a crop sprayer, air ambulance and aerial crane. The two prototypes were built under contract by Cunliffe-Owen. The first prototype crashed killing the crew in 1950. As a result, the private finance for Cierva was withdrawn and the second never flew.
