COMMENT: The Supermarine “Seafire” was a naval version of the Supermarine “Spitfire” adapted for operation from aircraft carriers. The name “Seafire” was arrived at by abbreviating the longer name “Sea Spitfire”.
In late 1941 and early 1942, the Admiralty assessed the “Spitfire” for possible conversion. In late 1941, a total of 48 “Spitfire” Mk Vb were converted to become “hooked Spitfires”. This was the “Seafire” Mk Ib and would be the first of several “Seafire” variants to reach the Royal Navy’s Fleet Air Arm. The second semi-naval variant of the “Seafire” and the first to be built as such, was the “Seafire F Mk IIc which was based on the “Spitfire” Mk Vc. The IIc was the first of the “Seafires” to be deployed operationally in large numbers. Although developed for aircraft carrier use, this version still lacked the folding wings needed to allow them to be used on board some Royal Navy carriers, some of which had small aircraft elevators unable to accommodate the full wingspan of the “Seafires”. The “Seafire” F Mk III was the first true carrier adaptation of the Spitfire design. It was developed from the “Seafire” Mk IIC, but incorporated manually folding wings allowing more of these aircraft to be spotted on deck or in the hangars below. Supermarine devised a system of two straight chordwise folds; a break was introduced immediately outboard of the wheel-wells from which the wing hinged upwards and slightly angled towards the fuselage. A second hinge at each wingtip join allowed the tips to fold down (when the wings were folded the wingtips were folded outwards). This version used the more powerful Merlin or Merlin 55M, driving the same four-bladed propeller unit used by the IIC series; the Merlin 55M was another version of the Merlin for maximum performance at low altitude. This Mark was built in larger numbers than any other “Seafire” variant; of the 1,220 manufactured Westland built 870 and Cunliffe Owen 350 aircraft. (Ref.: 24).

COMMENT: In 1941 the Air Ministry issued specification B.11/41 calling for a fast bomber operating from aircraft carriers. Beside high speed and bomb load main requirement was a lay out of the aircraft to give the pilot the best view possible for landing on aircraft carriers. Miles proposed a tandem wing experimental aircraft based on its M.39 design. To prove the concept Miles designed and built a 5/8th scale version, the M.39B Libulella which flew for the first time on July 1943. Flight evaluation showed no “undesirable handling” characteristics and its design coincided with interest by the authorities in unorthodox designs for large aircraft. The rear wing was higher than the forward one to avoid downwash and give ground clearance for the propellers. The M39B design had inboard flaps and outboard ailerons on the rear wing and the front wing had an auxiliary aerofoil/flap/elevator device, which could vary the wing area without changing lift coefficient. Miles continued testing, generating more flight data and submitted an improved M.39 design in early 1944. Meanwhile, the sole M.39B passed to the Royal Aircraft Establishment at Farnborough in 1944, where it was damaged and repaired after two accidents, only to be broken up with the full-sized bomber project’s cancellation (Ref.: 24).

COMMENT: The Fairey Firefly brought versatility to a degree previously unapproached in a carrier-borne aircraft. Despite the fact that its wartime career was relatively brief, the Firefly not seeing action until mid-July 1944, it fought in practically every operational theatre, from the Arctic to the Tropics, emerging as perhaps the most successful of British wartime shipboard aeroplanes. In 1939 the admiralty issued specification N.8/39 and N.9/39, which respectively called for a fixed-gun fighter and a fighter possessing a power-driven turret in which all armament was concentrated. The Fairey Company submitted designs for both specifications, but concluded that a clean two-seat fighter with fixed-gun armament offered greater potentialities. A design on these lines was accepted in principle, specification was revised to N.5/40, and an initial contract for 200 machines was ordered. On December 1941 the first prototype – the name “Firefly” was selected – made its initial flight. The first production aircraft was delivered in March 1943 and quantity production began in autumn 1942. The contract called for 800 aircraft and the first operational unit received the Firefy F.I. on October 1943. A total of 430 F.Mk.I are built by Fairey and under sub-contract by General Aircraft. The Firefly F.I was succeeded by the F.R.Mk.I fighter-reconnaissance aircraft carrying ASH shipping detection radar, a total of 376 aircraft were produced (Ref.: 12).

COMMENT: After Japan’s initial successes in the Pacific Area of Action, the need for a fighter aircraft capable of operating from austere island sites, with minimal infrastructure, was regarded as a high priority. So the British Air Ministry’s Specification N2./42 called for a retractable hull flying-boat fighter. The Blackburn Aircraft Company designed a water based fighter that utilized as much as possible of the structure of the Blackburn Firebrand torpedo striker fighter, just beginning flight tests at that time. A novelty was the retractable hull. The fuselage of the aircraft was to be split in two with the lower float-like half extending and retracting hydraulically. This resulted in an excellent streamline form with the main hull, and simultaneously provided adequate clearance between airscrews and water. The B.44 was well suited for the Pacific war. However, the project was cancelled because British Naval policy was only to use aircraft carriers with wheeled fighters (Ref.: 23 ).
