POWER PLANT: Two Rolls-Royce Merlin 61 liquid-cooled engines, rated at 1,520 hp each
PERFORMANCE: 440 mph at 28,000 ft
COMMENT: The possibility of Luftwaffe aircraft operating over the United Kingdom at altitudes beyond the capabilities of existing RAF fighters led the Air Ministry to the decision to call for a specialized high altitude interceptor according to specification F.16/40. Vickers tendered the Type 432, which at one time dubbed unofficially the “Mayfly” that flew for the first time in December 1942 some seven weeks after the competitive Westland P.14 “Welkin”. Embodying a pressurization system similar to that for the Wellington V and VI bombers, the Type 432 prototype had a relatively small, self-contained pressure cabin for the pilot whose head projected through a small, double-glazed dome or bubble which hinged to one side for better entrance and exit. Initial trials proved the Type 432 to be difficult to handle on the ground, although it processed an excellent performance once in the air, with a substantially higher maximum speed than that of the “Welkin”. Nevertheless, the Westland fighter was selected for production and flight trials with the sole Type 432 prototype continued until December 1944 when the machine was finally scrapped (Ref.: 12).
TYPE: Medium bomber, long-range reconnaicance. Project.
ACCOMMODATION: Crew of four
POWER PLANT: Two BMW 801G engines, rated at 1,770 hp each
PERFORMANCE: 373 mph in 26, 247ft (estimated)
COMMENT: In 1942 the RLM called for proposals for an “Arbeitsflugzeug” (“Work aircraft” or general-purpose aircraft) used as horizontal- and dive-bomber, torpedo and missile-carrier as well as long-range reconnaissance. Invited were aircraft companies such as Blohm & Voss, Dornier, Heinkel, and Junkers. Blohm & Voss presented the Bv P. 163, Heinkel the He P.1065, Junkers the Ju 88E (which later became the Ju 188), and Dornier the Do 417. In December 1942 the decision was made in favor of the Dornier design and the prototype Do 417 V1 was scheduled for first flight in August 1943. Mass production should start in April 1944. The Do 417 V1 was powered by a BMW 801G engine, while in the Do 417 V2 Daimler-Benz DB 603A engines should be installed. Finally, for production-reasons and because of higher speed the Junkers Ju 188 was favored for production. (Ref.: 17)
POWER PLANT: One General Electric XT31-GE-1 turboprop, rated at 2,300 h.p. and one Allison J 33-GE-5 turbojet, rated at 703 kp
PERFORMANCE: 507 m.p.h. at 30,000 ft
COMMENT: For the long distances in the Pacific Area a long-range fighter was needed. The combination of a turboprop in the nose and a turbojet in the rear fuselage was promising: The turboprop would be used for endurance cruising and the turbojet to boost performance in the action area. Two prototypes were ordered but only one completed and flown
