COMMENT: One of the most interesting flying boats to be built and flown during the war years was the Blackburn B.20 medium-range reconnaissance aircraft. The B.20 represented an attempt to reconcile the conflicting requirements for angles of incidence and correct streamlining between the conditions of take-off and level flight, and simultaneously provide adequate clearance between airscrews and water. The novel feature of the B.20 was the use of a retractable planning bottom. The pontoon was attached to the main hull by means of links so designed that when the pontoon was extended the hull and wings automatically assumed the best attitude for take-off. When the pontoon was retracted it presented a good streamline form with the main hull. The B.20 was first flown early in 1940 and a number of flights were made, the aircraft performing well both on the water and in the air, and the retractable pontoon operating successfully. Unfortunately, the B.20 was lost during a test flight and further development of the flying boat was abandoned in favor of the Saro “Lerwick”. However, during the war design work on a flying-boat fighter Blackburn B.44 employed the retractable pontoon principle, but this project never left the drawing-board (Ref.: 14).

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: The Fairey Albacore was a British single-engine carrier-borne biplane torpedo bomber built by Fairey Aviation between 1939 and 1943 for the Royal Navy Fleet Air Arm and used during the Second World War. It was designed for spotting and reconnaissance as well as level bombing, dive bombing and as a torpedo bomber. The Albacore, popularly known as the “Applecore”, was conceived as a replacement for the ageing Fairey Swordfish , which had entered service in 1936. The Albacore served with the Swordfish and was retired before it, being replaced by the Fairey Barracuda and Grumman Avenger torpedo bombers. A total of 800 Albacores were built (Ref.: 23).
POWER PLANT: One Bristol Pegasus III M3 radial engine, rated at 690 hp
PERFORMANCE: 143 mph at 5.000 ft
COMMENT: The Fairey Swordfish was a biplane torpedo bomber designed by the Fairey Aviation company, used by the Royal Navy Fleet Air Arm during World War II. Originating in the 1930s, the Swordfish, nicknamed “Stringbag”, was an outdated design by the start of the war in 1939, but remained in front-line service until the end of the hostilities in Europe outliving several types intended to replace it, e.g. the Fairey Albacore. It was initially operated primarily as a fleet attack aircraft. During its later years the aircraft was equipped with racks under the lower wings to enable the mounting of rockets and a large centrimetric radar in a fairing under the fuselage. It was used as an anti-submarine and training aircraft. When the production was halted in August 1944 a total 2,391 have been built (Ref.:23).
