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).
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 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).
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).
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)
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).
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).
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.
TYPE: Anti-ship and –fortification destroyer. Project
ACCOMMODATION: Pilot only in Me 262
POWER PLANT: Two Heinkel-Hirth HeS 011 turbojet engines, rated at 1,500 kp each (Ju 287) and two Junkers Jumo 004 turbojet engines, rated at 950 kp each (Me 262)
PERFORMANCE: 500 mph (estimated)
COMMENT: In desperate attempts to stop the forward rushing Allied troops several proposals were offered using different pilotless aircraft as guided missile in pickapack combination with a piloted leading aircraft (‘Mistel’, ‘Mistletoe’). They should be used against ships, fortifications, and troop concentrations. The unmanned aircraft with a large hollow-charge warhead was guided to vicinity of its target by a single-seat fighter temporarily attached to a superstructure above the fuselage. When the objective was reached, the pilot of the upper component set the controls to approach the target in a shallow glide, and at the appropriate distance detached his aircraft and climbed away, the pilotless lower component continuing on its set course.
In March 1945 a proposal was submitted using a variant of the brand new Junkers Ju 287 as guided missile in combination with the Messerschmitt Me 262. This Ju 287 was somewhat smaller than the original aircraft, had the same wing and tail arrangement, and was to be powered by two or four turbojet engines of various types. For take-off a special trolley was developed by Rheinmetall-Borsig. There is no evidence whether this project ever was seriously discussed with the authorities (Ref.: 16).
POWER PLANT: One Heinkel-Hirth HeS 011 turbojet engine, rated at 1,300 kp thrust
PERFORMANCE: 617 mph
COMMENT: At the end of 1944, when the construction drawings of the Messerschmitt Me P.1101 were completed, and in the light of the critical situation of Germany it became obvious that the production of that new fighter was too complicated and too expensive. Messerschmitt’s design bureau began work on a less advanced design that should be an intended improvement to the Messerschmitt Me P.1101. This Messerschmitt Me P.1106 based on the Me P.1101 but went through several redesigns. The first version had a short fuselage and a T-tail plane with cockpit faired into the vertical stabilizer. The second design had a short fuselage, too, the tail plane of butterfly style and the cockpit far aft. A third and final design had a longer and slim fuselage with a V-tail plane and the cockpit moved slightly forward. In all designs the wings were swept back at 40 degrees. The planned power plant was a Heinkel HeS 011turbojet engine, and armament was to be two 30 mm MK 108 cannon. Since the cockpit had poor visibility and calculated performance had not been improved compared to the Me P.1101, the Messerschmitt Me P.1106 project was abandoned (Ref.: 17, 22).
POWER PLANT: Two Heinkel-Hirth HeS 011 turbojet engines, rated at 1,300 kp thrust each
PERFORMANCE: 541 mph
COMMENT: A specification for a night fighter was issued by the RLM in late January 1944. Preliminary requirements postulated a top speed of 560 mph, an endurance of four hours, an internally mounted FuG 240 or FuG 244 radar, and an armament consisting of four cannon. Dr. Richard Vogt, chief engineer of Blohm & Voss Company, who designed the Blohm & Voss Bv P.212 jet fighter, contender of the “Jägernotprogramm” (Fighter emergency program), immediately began work of an larger aircraft to meet the specification issued for the new night fighter. On the basis of the Bv P.212 he designed the new aircraft, officially designated Blohm & Voss Bv P.215. The fuselage was short with an air intake in the nose leading the flow directly to the turbojet engines mounted in the rear fuselage. The wings featured a 30 degree swept back and 6 degrees of dihedral. The outer wing tips angled down at 23 degrees, and assisted stability and control. There were two small vertical fins and rudders located on the trailing edge of the wing, where the outer wing tips angled down. The nose landing gear was taken from a Heinkel He 219 “Uhu” and retracted to the rear, and the two main wheels retracted forwards into the fuselage. A pressurized cockpit held the three man crew seated on ejection seats. The defensive armament consisted on a remote controlled, rear-facing FHL 151 turret and two MG 151/20 cannon. Two bombs, SC 250 or SC 500 could be carried in a belly recess. On February 1945, the specifications for the future night fighter were upgraded, which none of the competitor’s designs were able to achieve. Although the Blohm & Voss Bv P.215 would have had good performance characteristics, it did not reach the new specifications either. Criticism concerned the short time of flight, stall at high speeds, caused by the short and thick fuselage, and uncertainty due to the unusual control units. Nevertheless, in March 1945, the design was chosen for further development. With the collapse of Nazi Germany any further work on that novel aircraft were stopped (Ref.: 17, 22).
