Mitsubishi J4M-1 Senden (Flashing Lightning, Luke), Unicraft, Resin

Gallery

TYPE: High performance interceptor fighter. Project

ACCOMMODATION: Pilot only

POWER PLANT: One Mitsubishi Ha-43 radial engine, rated at 1,650 hp at 26,247 ft, driving 6-bladed metal constant speed pusher propeller

PERFORMANCE: 470 mph at 26,247 ft

COMMENT: To provide the Imperial Japanese Navy with a land-based high-performance interceptor aircraft, Mitsubishi designed the J4M Senden (“Flashing Lighting”) or Navy Experimental 17-Shi Otsu B Type Interceptor Fighter Senden. It was to have been a single-seat, twin-boom, low-wing monoplane with a central nacelle housing an unstepped cockpit and a 2,130-hp Mitsubishi MK9D (Ha-43) radial engine behind the pilot driving a six-bladed pusher propeller rotating between the booms. The booms were to extend aft from the leading edge of the wing and were mounted below the central nacelle. The aircraft was to have had tricycle landing gear and an armament of one 30-mm and two 20-mm cannon. Design of the initial J4M1 version ended when the Navy put its support behind the competing Kyushu J7W fighter. So the J4M project did not proceed beyond the design stage. The Allies nonetheless assigned the J4M the reporting name “Luke” during World War II.(Ref.: 23)

Blackburn B.44 (Unicraft, Resin)

Gallery

TYPE: Flying-boat fighter and fighter bomber. Project

ACCOMMODATION: Pilot only

POWER PLANT: One Napier Sabre II, rated at 2.020 hp, driving two three-bladed contra-rotating propellers

PERFORMANCE: 360 mph

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 ).

Fighterbomber, Projects

Messerschmitt Me P.1101/101, (Unicraft, Resin)

Gallery

TYPE:  Medium bomber. high-speed fighter bomber. Project.

ACCOMMODATION: Crew of two

POWER PLANT: Four Heinkel-Hirth He S 109-011, rated at 1,300 kp each

PERFORMANCE: 650 mph (estimated)

COMMENT: In 1944 the Heinkel-, Arado- and Messerschmitt Aircraft Companies proposed to the RLM designs of a medium bomber with high speed and high bomb load. Power units should be high performance piston engines, rated at 3,000 to 6,000 hp, turbojet engines with more than 2,500 kp thrust, or turboprops with more than 6,500 hp. In summary all designs were ahead of the times, including high-speed profiles, variable-sweep wings up to 60 degrees and high subsonic speed.
Messerschmitt proposed the project Me P.1101/101, a design out of a whole series of developments with the designation Me P.1101. It featured a long, tapered fuselage and was powered by four Heinkel-Hirth He S 109-011 turbo engines , two mounted below the nose and two at the tail. Armaments were to consist of four MK 108 30mm cannons in the nose plus remote-controlled turrets, and a bomb load of 3.000 kg. The designs most distinguishing features were its swing-wings, which would allow it to land on short runways while accelerating to near supersonic speeds during interception missions. However, like so many ambitious aircraft projects during this period, the Me.P.1101/101 never made it past the design stage. (Ref.:14)

Nightfighter

Grumman F7F-3N Tigercat (Hasegawa)

TYPE: Carrier-borne night-fighter

ACCOMMODATION: Pilot and radar operator

POWER PLANT: Two Pratt & Whitney R-2800-34W Double Wasp engines, rated at 2,100 hp each

PERFORMANCE: 435 mph at 22,000 ft

COMMENT: After 34 single-seat Grumman F7F-1 Tigercats had been delivered, production switched temporarily to a two-seat night-fighting version F7F-2N. A prototype XF7F-2N had been produced by modifying the third production F7F-1 to have a second seat behind the pilot, for the radar operator, and AN/APS-6 search radar, installed in the nose in place of the four machineguns. Grumman produced 65 F7F-2Ns between October 1944 and August 1945. Night landings were made aboard the USS Antietam as well as USS Shangri-La. The first unit to convert to the night-fighting Tigercat was VMF(N)-533, which after working-up in Texas arrived on Okinawa on 14 August 1945, the day before the Japanese surrender.
The Grumman F7F-3N Tigercat shown here was a post-war variant with R-2800-34Ws engines, SCR-720 radar in the nose and a larger fin. In total 60 F7F-3Ns were produced. (Ref. 10)

 

Heavy Bomber, Assemblyships

Consolidated B-24D “Liberator” “The Little Gramper”, 491st BG (H) “The Ringmasters”, 8th USAAF (Airfix)

Gallery

TYPE: Heavy long-range bomber, in service as Assembly ship

ACCOMMODATION: Crew of four

POWER PLANT: Four Pratt & Whitney R-1830-43 Twin Wasp radial engines, rated at 1,200 hp each

PERFORMANCE: 303 mph at 25,000 ft

COMMENT: The Consolidated B-24D “Liberator” was the first variant to be qualified for combat. Under the original Production Pool plan, Consolidated/San Diego was the prime manufacturer, supplying components to Fort Worth and Douglas/Tulsa for assembly. In May, 1942 the first of 2,738 B-24D’s rolled off the assembly lines.
Due to rapidly changing needs, especially for defensive armament, there were many variations within the B-24D model, these differences identified by “production blocks” (e.g B-24D-70-CO). Nevertheless, B-24D’s have been very successful in the first years of bombing offensive in the European theater but later are replaced by B-24H and B-24J. These variants had more powerful engines and better defensive armament. Some bombardment groups used phased-out B-24Ds as assembly (formation) ships until the end of the hostilities. The B-24D Assembly (Formation) Ship “The Little Gramper” shown here belonged to the 491th Bombardment Group (H) „The Ringmasters“, stationed at North Pickenham. (Ref. 2)

NOTE: This model is not the Hasegawa kit. It is an Airfix kit I built many years ago. All is hand-painted direct on the model. Polka dots are used as mentioned with the Consolidated B-24J Assembly Ship of the 458th Bombardment Group (H)

Heavy Bomber, Reconnaissance, Cargo

Consolidated PB2Y-5 “Coronado” (Contrail Models, Vacu-formed)

Gallery

TYPE: Patrol bomber flying-boat

ACCOMMODATION: Crew of ten

POWER PLANT: Four Pratt &Whitney R-1830-92 Twin Wasp engines, rated at 1,200 hp each

PERFORMANCE: 213 mph at 20,000 ft

COMMENT: In June 1935 and July 1936, respectively, the US Navy ordered prototypes of large four-engine flying-boats in patrol bomber category from Sikorsky and Consolidated. The Consolidated design, Model 29,  made use of retractable wingtip floats similar to those on the Consolidated PBY “Catalina”, but in all other respects it was a wholly new design with high-mounted wing and a capacious hull with accommodation for a crew of ten.
The XPB2Y-1, as designated by the Navy, took-off first time on December 1937, but orders for the big new aircraft was delayed until mid 1939. First six production PB2Y-2s were delivered December 31, 1940, after a production contract for 210 PB2Y-3s was placed a month before. These “Coronados”, as the type was named, often carried ASV radar in a fairing just behind the cockpit. Several aircraft were redesigned and became PB2Y-5 and PB2Y-5R depending on the engines used. All “Coronados” were withdrawn from active service before the end of 1945. (Ref.  22)

Fighterbomber

Nakajima Ki-115 “Tsurugi” (Sabre) (MPM Model)

Gallery

TYPE: Suicide attack aircraft

ACCOMMODATION: Pilot only

POWER PLANT: One Nakajima Ha-35 radial engine, rated at 1,150 hp

PERFORMANCE: 342 mph at 9,185 ft

COMMENT: In January 1945, the Japanese Army instructed Nakajima to build a specially designed suicide attack aircraft. This was to be easy to build, maintain and fly, and provision had to be made in its design to carry a single bomb. Power was to be supplied by any air-cooled radial engine with a rating of 800 to 1,300 hp. Maximum speed was specified at 211 mph with the undercarriage in position and 320 mph after jettisoning.
The first prototype was completed in March 1945 and flight tests began immediately. As could be expected from such a crash program, the results were disappointing and several modifications were required before handing the aircraft to pilots with limited experience. Provision was made on the 104 production aircraft for two solid-fuel rockets under each wing to boost the aircraft’s speed in its final dive. None of these aircraft became operational before the war ended. (Ref 1.)

TYPE: Bomber, heavy fighter. Project.

ACCOMMODATION: Crew of three

POWER PLANT:Two BMW 801E radial engines, rated at 1,550 hp each

PERFORMANCE: 400 mph at 19, 685 ft (estimated)

COMMENT: In 1942 Heinkel Aircraft Company was working on concepts for a new multi-purpose aircraft, able to fulfill different operational duties. Seven designs were elaborated that differed in many aspects.
Four designs, proposed as ”Versions I”, were competitors of the Junker Ju 288. He P. 1065 Ia was a two-engine bomber or heavy fighter, powered by two BMW 801E, rated at 1,555 hp each or two Junkers Jumo 222C engines, rated at 2,600 hp each. “Version Ib” was a somewhat different bomber and powered by two Junkers Jumo 222C engines, rated at 2,100 hp each. All designs had tail units with twin fins and rudders. He P. 1065 Ic was a twin-engine fast bomber design, powered by two Daimler-Benz DB 609 engines, rated at 2,270 hp each and conventional tail fin and rudder. The design was forerunner of what was projected as Heinkel He 319 V1.
Heinkel He P. 1065 IIc was an asymmetric low wing airplane, comparable to the Blohm & Voss Bv 141, proposed as a fighter bomber and powered by either BMW 803, rated at 3,500 hp or Daimler-Benz DB 619 engines, rated at 4,540 hp.
Finally, “Version III”, was a further development of the Heinkel He 119 as a fast bomber.  He P. 1065 IIIb should be powered by one Daimler-Benz DB 619, rated at 4,450 hp and had a tail unit with twin fins and rudders. Heinkel He P. 1065 IIIc was powered by one Daimler-Benz DB 613, rated at 3,100 hp and had conventional tail fin and rudder. This project should be further developed into Heinkel He 519. None of the seven projects were realized (Ref.: 19)

Rikugun Ki-93-Ia (A+V Models, Resin)

Gallery

TYPE: Twin-engined heavy fighter and ground attack aircraft

ACCOMMODATION: Crew of two

POWE PLANT: Two Mitsubishi Ha-214 radials, rated at 2,400 hp each

PERFORMANCE: 388 mph at 27,230 ft

COMMENT: The Rikugun Ki-93 was the last heavy fighter and ground-attack aircraft built in Japan during WW II and was the only design of the Rikugun Kogugijutsu Kenkyujo (Army Aerotechnical Research Institute) to be flown. Powered by two 2,400 hp Mitsubishi Ha-214 air-cooled radials driving six-blade propellers, the aircraft was designed specially to carry large caliber cannon in its under-fuselage gondola. Thus the Ki-93 was designed to perform as a high-altitude heavy bomber destroyer as well as a low-altitude anti-shipping aircraft. In its bomber destroyer form (Ki-93-Ia ) the aircraft carried offensive armament comprising one 57 mm Ho-401 cannon and two 20 mm Ho-5 cannon, while for the anti-shipping missions its offensive armament  comprised one 75 mm Type 88 cannon and two 250 kg bombs (Ki-93-Ib).
Production of the Ki-93 was entrusted to the Dai-Ichi Rikugun Kokusho (First Army Air Arsenal) at Tachikawa and the first prototype was completed and flown in April 1945. A second prototype, the Ki-93-Ib in ground attack configuration, was completed but not flown before the end of the hostilities. (Ref.: 1)

Heinkel He 162D (A+V Models, Resin)

Gallery

TYPE: Target-defence interceptor. Project

ACCOMMODATION: Pilot only

POWER PLANT: One Heinkel-Hirth HeS 011A turbojet, rated at 1,300 kp

PERFORMANCE: 565 mph at 19,685 ft (estimated)

COMMENT: The Heinkel he 162D was a parallel development  to the Heinkel He 162C what was essentially similar but featured a swept-forward wing. There appeared to be certain advantages to be gained by sweeping the wing surfaces forward towards the tips, the critical Mach number being similar to that for an equal angle of sweepback but the tip stall tendency being removed and thus permitting higher taper ratios in both planform and thickness.
Swept-forward wings were also tested or designed in Germany by Junkers with Ju 287, EF 122, 125, EF 131, by Blohm & Voss with Bv P.209.02, and in the United States with Cornelius XFG-1 fuel-transport glider.
Neither the Heinkel He 162C nor the He 162D took-off into the air. But when the Heinkel factory at Schwechat, Austria, was occupied by Allied troops, a half-completed prototype for the Heinkel-Hirth HeS 0114A-powered B- model was found, this having interchangeable swept-back (He 162C) and swept-forward wings (He 162D).
