Martin-Baker 12 Gun Fighter (Unicraft, Resin)

TYPE: Long-range escort fighter. Project


POWER PLANT: Two Rolls-Royce Merlin III engines, rated at 1,030 hp each

PERFORMANCE: No data available

COMMENT: Prior to WWII, the major world powers knew they needed long-range fighters to escort their bombers deep into enemy territory. To this end, the British aircraft company Martin Baker submitted an innovative design for a tailless, twin-engine fighter armed with 12 heavy machine guns. Its rudder gone to help reduce drag, the plane would use the trailing ends of its engine nacelles for lateral control supplemented with ducted engine exhaust gases as well as propeller induced air stream. Although seriously evaluated by the RAF, the Martin Baker 12 Gun Fighter never made it past the design stage.

Boulton Paul P.99 (Unicraft, Resin)

TYPE: Interceptor, low/medium altitude fighter. Project.


POWER PLANT: One Rolls-Royce “Griffon II” engine, rated at 2,220 hp

PERFORMANCE: 315 m.p.h. at 17,000 ft

COMMENT: The Boulton Paul P.99 was one of several high-performance fighter projects of the Royal Air Force during WW II. The P. 99 was a twin-boom design, the Griffon engine was mounted in the rear driving two contra-rotating pusher propellers. This arrangement allowed the pilot an excellent visibility.

Hawker P.1048 (Unicraft, Resin)

Type: Two Turbojets Single Seat Fighter Project
Competitor to the Gloster Meteor

Supermarine Type 327 “Spito” (Unicraft, Resin)

TYPE: Fighter


POWER PLANT: Two Rolls-Royce Merlin liquid-cooled engines, rated at 1,240 hp each

PERFORMANCE: 450 mph at 15.000 ft

COMMENT: The Supermarine Type 324 and Type 325 were British two-engined fighter designs proposed as the replacement for the Supermarine Spitfire and Hawker Hurrican. Neither of them nor a revised design – the Type 327 – to carry cannon was accepted for development and production.
As an aircraft to succeed the Hurricane and Spitfire then entering service, Air Ministry specification F.18/37 required a 400+ mph (at 15,000 ft) fighter with twelve .303 inch machine gun armament.
Hawker Aircraft submitted a single seat, single engine design with two possible engines, the Hawker Typhoon powered by the Rolls-Royce Vulture and the Hawker Typhoon, with Napier Sabre engine.
Gloster submitted two similar twin-boom designs with 12 Browning machine guns in the nose and a pusher Napier Sabre engine as well as an adaptation of their proposal to F.9/37 with nose-mounted armament.
Bristol’s design was one airframe offered with three alternative engines.
In 1938 Supermarine submitted brochures describing the Type 324 (under the company specification No.458) along with the Type 325. Both were compact twin-engine designs – one tractor and one pusher – with either Rolls-Royce Merlin or Bristol Taurus engines.
Hawker’s designs – which Sydney Camm had been working on since April 1937 – were accepted and prototypes of each ordered.
The Type 324 was a low-wing, twin-engined monoplane featuring the elliptical wing shape of the Spitfire, with retractable tricycle undercarriage.
Twin engines were expected to give a maximum speed of 450 mph. In addition, the twin layout gave the usual advantages of torque cancellation, improved pilot view, tricycle landing gear, performance, improved take-off performance and allowed the use of the proven Rolls-Royce Merlin engine.
The structure of the aircraft was Alclad aluminium alloy. The wing was designed in sections, so that alternative engines (Bristol Taurus) or armament could be accommodated. Fowler flaps were fitted for take-off/landing. Spoiler flaps were fitted to improve performance.
A number of armament types were considered. The main was 12 Browning in two packs of six in each wing outer section; these could be removed complete with ammunition to allow rapid rearming and servicing of the weapons.
When the Air Ministry felt progress on the Westland Whirlwind cannon-armed fighter was too slow, they asked for the F.18/37 tenders to be revised with 20mm cannon armament. Supermarine dropped the pusher design and proposed a six-cannon fighter as the Type 327 Spito. The Ministry did not feel its advantages outweighed other considerations, and that the Whirlwind – or the adaption oft he Bristol Beaufort – would enter service before Supermarine’s design could (Ref.: 24).

Gloster ‘Meteor’ F. I Trent Turboprop (MPM)

TYPE: Experimental testbed


POWER PLANT: Two Rolls-Royce RB.50 Trent turboprop engines, rated at 750 hp and 570 kp thrust each


COMMENT: Experimental works with early jets proved that in the speed range of less than 450 mph the substantial reduction of fuel consumption can be obtained by fitting a reduction gearbox to the impeller of a turbojet engine driving an airscrew. In German companies such as BMW, Heinkel and Junkers were pioneers related to this new power unit and some of these were in an advanced stage of realization (Messerschmitt Me 262B-2 “Turboprop”), but the end of the war stopped all further works. Also in the UK this idea was materialized by Rolls- Royce in the form of a ‘Trent’ turboprop engine what was in fact a modified ‘Derwent’ turbojet, fitted with shaft reduction gearbox and five-bladed Rotol propellers. Two ‘Trent’ turboprops were installed in a Gloster ‘Meteor’ F. 1 turbojet fighter as a test bed. The aircraft needed little modification for the accommodation of the ‘Trent’ power plant, though the nacelles were somewhat larger, which, with the extra side area of the propellers, entailed the fitting of two small auxiliary fins towards the outboard end of the tail plane to ensure directional stability. The Gloster ‘Trent’-Meteor and became the first aircraft to take-off and fly solely on turboprop power on September, 1945. By March 1948 the development program had been completed. The results of it were embodied in highly successful Rolls-Royce ‘Clyde’ and ‘Dart’ turboprop engines (Ref.: 24).

Westland Welkin Mk.I (Czechmaster, Resin)

TYPE: High-altitude Interceptor


POWER PLANT: Two Rolls-Royce Merlin 76/77 liquid-cooled engines, rated at 1,250 hp each

PERFORMANCE: 387 mph at 26,000 ft

COMMENT: The Westland Welkin was a British twin-engine heavy fighter from the Westland Aircraft Company, designed in 1940 to fight at extremely high altitudes, in the stratosphere. Westland had some expertise in twin-engine aircraft; its Whirlwind Mk.I escort fighter was in full production. The word Welkin means “the vault of heaven” or the upper atmosphere. As mentioned, first conceived in 1940, it was built from 1942–43 in response to the arrival of modified Junkers Ju 86P bombers flying reconnaissance missions that suggested the German Luftwaffe might attempt to re-open the bombing of England from high altitude. But the threat was never materialized. Consequently, Westland produced only a small number of Welkins. In total 77 aircraft were built but only few of these flew. Most of the aircraft were produced without engines. One sole aircraft was modified as Welkin II which had a lengthened nose to accommodate A.I. radar (Ref.: 23).
