Ich hau' noch einen raus... was wäre, wenn Brewster nicht dicht gemacht hätte und es eine Weiterentwicklung der pummeligen und recht glücklosen Buffalo gegeben hätte? Z. B. die Brewster Bison!

Some Background:
The Brewster F3A Bison was an American fighter aircraft which saw limited service in World War II. It was in improved successor to the F2A Buffalo, a naval fighter which had won a competition against the Grumman F4F Wildcat in 1939 and became the U.S. Navy's first monoplane fighter aircraft. Although superior to the Grumman F3F biplane it replaced and the early F4Fs, the Buffalo turned out to be a disappointment because the weight of added equipment was not balanced by an increase in horsepower.

Several nations, including Finland, Belgium, Britain and the Netherlands, ordered the Buffalo. Of all the users, the Finns were the most successful with their Buffalos, flying them in combat against early Soviet fighters with excellent results. That encouraged Brewster to develop a more advanced, purely land-based version that would surpass the “B-339” export model’s performance – especially for the Pacific theatre where the F2A proved to be totally inferior to Japanese types like the agile Ki-43 and A6M.

The modified prototype, internally called Type 340, still based on the F2A-3, flew in late 1942. It primarily featured an uprated R-1820 radial engine and a longer fuselage to compensate for a slightly elongated nose – also as a measure to improve directional stability. The cockpit canopy had been changed into a frameless design, too. Armament was only marginally improved: the F2A’s four 0.5” machine guns were retained, but all of them went into the reinforced wings. As a novelty, though, wet wing hardpoints for heavier loads and drop tanks were added, as well as attachments for unguided missiles – up to six of them could be carried.

In due course of the tests it became clear that more aerodynamic refinements had to be made. Landing speed had become excessive (even for a land-based aircraft) and aerial handling was poor. Hence, all wing surfaced were enlarged and finally in summer 1943, when production was about to start, the modifications had become so severe (about 60% of the airframe had been redesigned) that the Type 340 received a new designation – the F4A ‘Bison’ (the F3A code had I the meantime been allocated to F4U Corsairs that were built a Brewster).
At that time, initial orders had only come from the Australian Air Force, from New Zealand and the Netherlands for its East Indies Air Force. The USA would not order it, since more capable – but bigger – aircraft like the F4U and F6F were already in production and service, so the F4A designation was quickly dropped and the export versions called the Bison Mk. I.

The initial production batch for the Netherlands was delivered to Australia, though, since the ML-KNIL had become integrated into the Commonwealth forces in the Pacific. The first Bison Mk. Is were delivered in May 1943 to RAAF No. 79 Squadron, when the squadron was established as a fighter unit equipped with Supermarine Spitfires and Brewster Bisons. No. 82 Squadron followed in August 1943.
A totally of only 72 Bisons were built, because the Brewster Aeronautical Corporation more and more drifted into serious trouble. The service aircraft saw constant field modifications, though, with better air filters and modified armament – the original four 0.5” machine guns (Mk. Ia) were soon modified to two machine guns plus two Australia-built 20mm Hispano cannons (Mk. 1b) and eventually to a full four 20mm cannons (Mk. 1c), which were successfully used in the ground attack role.

Anyway, the Bison had already stretched the Buffalo’s potential, so the type was retired from front line service in early 1945 and relegated to the training role.

Das Ganze ist eine heftig umgebaute Matchbox-Buffalo mit zahlreichen Transplantaten & Mods:
· Neu Haube einer späten F4U (Italeri)
· Motorhaube & Räder einer Curtiss SC-1 (Smer)
· Propeller einer B-17 (Airfix)

· Höhenleitwerk einer BAC Strikemaster (Matchbox)
Dazu wurde der Rumpf hinterm Cockoit um rund 5mm gestreckt - klingt nicht nach viel, musste aber wegen der längeren Haube vorne wg. der Proportionen sein.

Die Lackierung ist "klassisch" in RAF Dunkelgrün/Ozeangrau, allerdings mit himmelblauen Unterseiten, was im Pazifik häufiger vorkam. Die Markierungen sind fiktional, aber insofern korrekt als dass sie wirklich zu einer Maschine der No. 82 Squadron der RAAF gehören. :)

Schön gebaut und abgefahren gut bemalt - mag ich sehr!

Ich finde es schade, dass dizzys tolle whifs hier so versteckt gezeigt werden, für mich ist das auch fiction & fantasy. :dontknow:

Wieder eine schöne Arbeit von Dir.
