POWER PLANT: Four Heinkel/Hirth HeS 011 turbojet engines, rated at 1,300 kp each

PERFORMANCE: 565 mph

COMMENT: The Heinkel He 343 was a four-engine jet bomber project by Heinkel Aircraft Company in the last years of WW II. In 1944 a total of 20 of these aircraft were ordered. For shortening the development time and for re-use of existing parts, its general design was envisioned along the lines of an enlarged Arado Ar 234 “Blitz” (“Lightning”). For a choice of engines, the Junkers Jumo 004 and the Heinkel HeS 011 were planned. The DFS (Deutsche Forschungsinstitut für Segelflug), (German Research Institute for Gliding Flight) was involved in the project and created the project known as P.1068. By the end of 1944, work was nearly finished by the Heinkel engineers, with parts for the He 343 prototype aircraft either under construction or in a finished state, when the order was cancelled due to the “Jägernotprogramm (Emergency Fighter Program). Four versions were planned: the He 343A-1 bomber, the He 343A-2 reconnaissance aircraft, and the He 343A-3 and He 343B-1 “Zerstörer” (“Destroyer”) heavy fighters.
The Heinkel He 343A-1 was to be the bomber version. Depending on the engines used, the bomb load ranged between 2000 kg to 3000 kg, with 2000 kg to be carried internally, and 1000 kg to be carried externally. Trials were to be held with the Fritz X radio controlled bomb, which would have also added a third crew member. Defensive armament consisted of two fixed rear firing MG 151 20 mm cannon with 200 rounds each, which were mounted in the rear fuselage. None aircraft was completed. However, after WW II the Soviet Union utilized the design as the basis for the development of the Ilyushin Il-22, changing some of the parameters such as size and crew numbers. One prototype was built and flown. The results of the tests were used in development of the Ilyushin Il-28 (Ref: 24).

COMMENT:  In 1944, Focke-Wulf Aircraft Company projected three designs of a bomber using two Heinkel-Hirth He S 011 turbojets. These bombers were known under the unofficial designation  3 x 1000 Bomber-Projekt A, Projekt B and Projekt C. The designation “1000x1000x1000” meant that the aircraft could carry a 1000 kg (2205 lbs) bomb load over a distance of 1000 km (621 miles) and at a speed of 1000 km/h (621 mph).
The second design under the Focke-Wulf  internal designation Fw P.031 0239/10 “3×1000 Bomber, Projekt B” was of a flying wing layout. There was a small fuselage which held the cockpit and forward landing gear. The wing was swept back at 35 degrees and the fuel load in flexible tanks was carried ahead of the main wing spar. The engines and main landing gear were located behind the main wing spar. Two Heinkel-Hirth He S 011 jet engines each developing 1300 kg of thrust were fed by air intakes located in the wing leading edge near the wing roots.  The wing tips were bent downwards to act as vertical stabilizers and contained small rudders.  The ailerons also served as elevators and in addition small deflectors were mounted within the jet exhaust, one of the first uses of thrust vectoring.  The main landing gear retracted inwards and the nose gear swung up and forward. A single pilot sat in the extensively glazed cockpit located in the extreme nose, and no armament was planned at this stage in the development. A 1000 kg bomb load could be carried in the internal bomb bay located in the center wing. Since these designs would have taken several years to complete, the end of the war ended all development (Ref.: 17).

COMMENT: In autumn 1944 the Focke-Wulf company proposed three different designs of fast bombers to meet the RLM’s “1000×1000×1000 Bomber” requirement. The request for proposals called for an aircraft with two turbojet engines and should be able to carry 1,000 kilograms (2,200 lb) of bombs over a distance of 1,000 kilometers (620 mi) with a speed of 1,000 kilometers per hour (620 mph). The third design (Projeckt C) was of conventional layout similar to the first design (Projekt A, while Projekt B was a flying wing design. Projekt C had wings and tail plane of parallel chord and the fuselage was deepened. The two Heinkel-Hirth HeS 011 turbojet engines were on underwing pylons to increase the mass-balance effect. They were also turned out of line to help enhance single engine controllability. The pilot was positioned in a forward cockpit, and one 1000 kg bomb (Hermann) could be carried. As with the other two other bomber projects the Focke-Wulf  Fw 1000x1000x1000 Bomber Projekt C remained on the drawing board (Ref.: 16).

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)

The Heinkel He 343B-1 differed from the He 343A-1 bomber version especially in the tail unit. Instead of the two fixed rear firing guns in the fuselage rear, a FHL 151Z remote controlled turret was installed in the extreme rear fuselage. This necessitated a tail redesign to a twin fin and rudder set up. A rear facing periscope in the cockpit was used to aim the FHL 151Z turret, which was armed with two MG 151 20mm cannon. The twin tail would have made for extended flight testing, plus would have added additional weight and drag (Ref.: 17, 24).
