Junkers EF 128 Nachtjäger (Night fighter), (Planet, resin)

TYPE: Night- and all-weather fighter. Project

ACCOMMODATION: Pilot and radar observer

POWER PLANT: One Heinkel-Hirth HeS 011 turbojet engine, rated at 1,200 kp

PERFORMANCE: 621 mph at 23,000 ft, estimated

COMMENT: In mid 1944 the OKL (Oberkommando der Luftwaffe, Luftwaffe High Command) issued to tender a development request calling for a fighter powered by a Heinkel He S 011 turbojet engine. Required were a top speed of 612 mph at 23,000 ft and an armament of four MK 108 cannon.  In contrast to the single-seater, proposed by Blohm & Voss, Bv P.212, Focke-Wulf, Ta 183, Heinkel, He P.1078, and Messerschmitt, Me P.1110, Junkers presented the project EF 128 as a two-seater all-weather fighter. In two conferences between the aircraft companies, the OKL and the DVL, held in December 1944 and January 1945, all designs were evaluated. Finally chosen was the design of Junkers EF 128, as well as single-seater, and as two-seater. The production should start in mid 1945. Due to the compact fuselage and the relative high cross section it was possible to seat the crew side-by-side in an pressurized cockpit and to integrate newest radar equipment such as FuG 240 “Berlin” (Ref.: 20).

Blohm & Voss Bv P.193.01-01 (Planet, Resin)

TYPE: Ground attack fighter, dive bomber. Project

ACCOMMODATION: Pilot only

POWER PLANT: One Junkers Jumo 213A inline engine, rated at 1,750 hp

PERFORMANCE: 354 mph, estimated

COMMENT: Independent from each other the design teams of Blohm & Voss, Dornier and Focke-Wulf worked on projects with mid-mounted engines, driving pusher propellers via a long extension shaft. By that the pilot had an excellent view and a wide field of fire. Furthermore it was possible as far as a night- or bad-weather fighter was concerned to install a radar equipment. Dornier worked on the projects Do P.247 and Do 252 and Focke-Wulf on the Fw P.0310251. The Blohm & Voss team designed a ground attack/dive bomber that was similar to the Bv 192.01-01. A Junkers Jumo 213A engine drove a three-bladed pusher propeller via a very long extension shaft and a single fin and rudder was mounted beneath the fuselage to protect the propeller during take-off and landing. The wing had a straight leading edge and tapered trailing edge and a tricycle undercarriage was provided. The armament consisted of two MK 103 30mm cannon in the wings and two MG 151/20 20mm cannon on the nose sides. A bomb load up to 1,000 kg could be carried (Ref.: 17, 18).

Messerschmitt Me P.1110 “Ente” (“Duck“) (Classic Plane, Resin)

TYPE:  High-altitude interceptor. Project

ACCOMMODATION: Pilot only

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

PERFORMANCE: 631 mph

COMMENT: The Messerschmitt Me. P.1110 “Ente” (“Duck”) was the third variant of the Me P. 1110 projects proposed for the “Jägernotprogramm” (Emergency Fighter Program). It was of canard configuration with small wings in the front and larger wings in the rear part of the fuselage. This was felt would allow good pitch and lateral stability at low-speed flight characteristics. The air intakes were located on the fuselage sides like in the Me P.1110/I.  The cockpit was located at the nose end of the plane and the wings had a 40° wing sweep back. Projected maximum speed was 631 mph. As with the other two Messerschmitt Me P.1110 designs the project would be soon dropped in favor of the Junkers EF 128 (Ref.: 17)

Blohm & Voss Bv P.192.01-01 (Planet, Resin)

TYPE: Ground attack and dive bomber. Project

ACCOMMODATION: Pilot only

POWER PLANT: One Daimler Benz DB 603G liquid-cooled engine, rated at 1,750 hp

PERFORMANCE: No data available

COMMENT:  This project of a ground attack and dive bomber was one of the most unusual designs of Dr. Vogt and his team. The front part including the cockpit was completely separate from the fuselage and only held by two booms projecting from the wing leading edge. A Daimler Benz DB 603 engine, located mid-fuselage immediately behind the cockpit, drove a four-bladed propeller rotating around the fuselage. The wing had a straight leading edge and was pronounced taper on the trailing edge. The aircraft had a tricycle landing gear and was heavily armed with two MG 151/20 20mm cannon located in the nose and two MG 151/20 20mm cannon located in the twin booms that held the front part. Also up to 500 kg bomb load could be carried. This project was never realized (Ref.: 17, 18).

Junkers Ju 268 with Heinkel He 162A-2 (“Mistel 5”, “Mistletoe 5”) (Ju 268 completely scratch-built, He 162 Revell)

TYPE: Anti-ship and -fortification destroyer. Project

ACCOMMODATION: Pilot only in the Heinkel He 162

POWER PLANT: Two BMW 003A-1 turbojet engines, rated at 800 kp thrust each in the Ju 268 and one BMW 003A-1 turbojet engine in the He 162A-2

PERFORMANCE: 497 mph

COMMENT: The Junkers Ju 268 was the un-manned bomber component of the “Mistel 5” parasite bomber project designed in Germany during 1944.It was a composite bomber comprising a Heinkel He 162A-2 piloted component and a specially developed Arado E377 glider bomb. Due to shortages at the Arado design offices, several other composites were studied as replacements for the Arado E377, and in late 1944 Junkers proposed the Ju268 as an alternate bomber component for the “Mistel 5”, with a Messerschmitt Me 262 studied as an alternative piloted component. The Ju 268 was simply designed with a cylindrical wooden fuselage, a hollow-charge of up to 10 tons of explosive in the nose part, rectangular mid-mounted wings, and a cruciform un-swept tail unit. A jettisonable tricycle landing gear was fixed attached to the fuselage during take-off only and power was provided by two BMW 003 or Junkers Jumo 004 turbojet engines. For suicide- or “Kamikaze”-missions a manned version of the Ju 268 was under study with a glazed cockpit section in the front of the aircraft. No further details are known and the project never left the drawing-board (Ref.: 20, 24).

Messerschmitt Me P.1110/I (Planet, Resin) with Kramer X-4 (Scratch-built)

TYPE: High altitude interceptor. Project

ACCOMMODATION: Pilot only

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

PERFORMANCE: 621 mph

COMMENT: As part of the “Jägernotprogramm” (“Emergency Fighter Program”) at the beginning of 1945 a program was launched by the OKL for a new generation of fighter/interceptor aircraft in order to replace the Heinkel He 162 “Salamander” or “Volksjäger” (“Peoples fighter” as called by the authorities). The new aircraft was intended to have superior performance in order to deal with high-altitude threats such as the Boeing B-29 “Superfortress”. Messerschmitt designed three different single-seated, high-altitude fighter projects which were submitted in February 1945. One of the designs of the Messerschmitt Me P.1110 series was a turbo-jet powered interceptor with a conventional-looking design with the air intakes located on the fuselage sides (“Rampen-Einlauf”, “Ramp-air-intake”). The wings were swept-back at 40 degrees, as well as the tail-plane. Power was provided by a single Heinkel HeS 011 turbojet engine, projected maximum speed was 621 mph. The project would be soon dropped in favor of the Junkers EF 128 and none of the Messerschmitt designs made it to the prototype stage (Ref.: 17).

Messerschmitt Me P.1104/II (A+V-Models, Resin)

TYPE: Short-range interceptor. Project

ACCOMMODATION: Pilot only

POWER PLANT: One Walter HWK 509A-2 liquid-fueled rocket, rated at 1,700 kp

PERFORMANCE: 503 mph

COMMENT:  In mid 1944 the RLM called for proposals of a small, cheap, easy to build, reusable short-range, high speed interceptor in the context of the ‘Miniaturjägerprogramm’ (Miniature fighter program).  Aircraft companies such as Bachem,  Focke-Wulf, Heinkel, Junkers and Messerschmitt submitted proposals: Bachem Ba 349 ‘Natter’ (‘Grass Snake’), Focke-Wulf Fw ‘Volksjäger’, (‘People Fighter’), Heinkel He P.1077 ‘Julia’, Junkers EF 126 ‘Lilli’, Junkers EF 127 ‘Walli’ and Messerschmitt the designs Me P.1103 and Me P.1104, each in several variants. The Messerschmitt Me P.1104/II design was a simple wooden construction with a cylindrical fuselage, the wings were shoulder-mounted and un-swept so as the tail-plane. Power was provided by a Walter HWK 509A-2 liquid-fuel rocket engine with a main combustion chamber of 1.700 kp thrust and a smaller cruising chamber of 300 kp thrust. The pilot was in a conventional seated position, the armament consisted of one single MK 108 30 mm cannon beneath the cockpit.  For take-off the fighter was positioned on a trolley so as the Messerschmitt Me 163 ‘Komet (‘Comet’) that was jettisoned when the aircraft was airborne. The tiny plane was towed by a Messerschmitt Me 109G or Messerschmitt Me 262A-1 towards the enemy, released when in attack position and ignited the rocket motor. After attack the aircraft glided back to its base and landed on retractable skids. As with projects of other companies all work was cancelled in favour of the Bachem Ba 349 ‘Natter’ (Ref.: 17, 20)

Messerschmitt Me 262C-3a ‘Heimatschützer IV’, (Home Protector IV’) (Revell, Parts scratch-built)

TYPE: Interception fighter

ACCOMMODATION: Pilot only

POWER PLANT: Two Junkers Jumo 004C turbojet engines, rated at 980 kp each and one Walter HWK 509S-2 liquid-fueled rocket engine, rated at 1,700 kp

PERFORMANCE: 510 mph at 32,800 ft

COMMENT: The major disadvantage displayed by the ‘Heimatschützer I’ had been the strict limitation imposed on J2 tankage (for the Jumo 004 turbojet engines) by the internally mounted rocket motor, and the need to use some of the available tankage for its propellants. The Messerschmitt Me 262C-3a ‘Heimatschützer IV’, therefore, had a Walter R II-211/§ rocket motor slung beneath the fuselage with ‘C-Stoff’  and ‘T-Stoff’ tanks  mounted on modified bomb carriers immediately ahead of the power plant. The rocket motor was jettisonable, and was to be dropped by parachute after the fuel had been consumed. Fuel was fed to the power plant by means of a flexible line, but difficulties were encountered with the fuel feed as a level of tanks was slightly below that of rocket combustion chamber, and these had not been resolved when further work on the Messerschmitt Me 262C-3a ‘Heimatschützer IV’ terminated.
Another ‘Heimatschützer’, the Messerschmitt Me 262C-3 ‘Heimatschützer III’ was a proposed version of the basic Me 262A-1a with Junkers Jumo 004 turbojet engines replaced with Walter HWK RII-211 liquid-fueled rocket engines (Ref.: 7).

Messerschmitt Me P. 1103/III (A+V Models, Resin)

TYPE: Short-range interceptor. Project

ACCOMMODATION: Pilot only

POWER PLANT: One Walter HKW 509A-1 liquid-fueled rocket, rated at 1,600 kp

PERFORMANCE: 435 mph

COMMENT: In 1944, according to the RLM’s ‘Miniaturjägerprogramm’ (Miniature fighter program) the Messerschmitt Me P.1103/III was designed as a small, cheap, easy to build, short-range, high speed interceptor fighter. Competitors were Focke-Wulf Fw ‘Volksjäger’, Junkers EF 126 ‘Lilli’, Junkers EF 127 ’Walli’ and Bachem Ba 349 ‘Natter’. Construction was to be simple, the airframe mainly built from wood. The wings were mid-mounted and un-swept so as the tail-plane. For take-off the fighter set on a simple pair of wheels and a front skid. Both were jettisoned when the aircraft was airborne. The tiny plane was towed by a Messerschmitt Me 109G or Messerschmitt Me 262A-1 towards the enemy, released when in right position and ignited the rocket motor. After attack the aircraft glided back to its base and landed on retractable skids. All design work was cancelled in favour of the Bachem Ba 349 ‘Natter’ (Ref.: 17).

Messerschmitt Me 262B-2 with Heinkel-Hirth HeS 021 Turboprop (Revell, Parts from Unicraft, Resin)

TYPE: Long-range night- and all-weather fighter. Project

ACCOMMODATION: Crew of two, pilot and radar observer

POWER PLANT: Two Heinkel-Hirth HeS 021 turboprop engines, rated at 3,300 hp each

PERFORMANCE: No data available

COMMENT: From the onset Messerschmitt engineers worked on several modification of the basic Me 262 ‘Schwalbe’ and ‘Sturmvogel’ designs, e. g. with different equipment, engines, electronics and weapon systems. Some of them were realized, others remained in project status. The availability of new and powerful turboprop engines was of great interest for long-range aircraft, especially for night- and all-weather fighters. The main advantage of this new power unit was the relative little fuel consumption, compared with the turbojet engines at that time, and by that an extended time of flight. Pioneers on that field were BMW (BMW 028, 5,440 hp), Daimler Benz (DB ZTL, 2,000 hp), Heinkel,( HeS 021, 3,300 hp), and Junkers (Jumo 022, 6,000 hp). None of these engines were completed and tested, but some in a very advanced stage.
This Messerschmitt Me 262B-2 design  dates back to early 1945. Based on an airframe of a two-seater Me 262B, two Heinkel-Hirth HeS 021 turboprops, each driving six-bladed propellers, should be installed. As with many other projects this design remained on the drawing board until the end of the hostilities. After the war similar designs were developed and flown in the UK, the Gloster ‘Trent Meteor”, and the US the Convair XP-81, and the Ryan F2R-1 ‘Dark Shadow’, respectively.
