Long Range Heavy Bomber
In the summer of 1935 Dornier and Junkers received specifications for a long-range heavy bomber and did not share the initial concerns about the Uralbomber. In early autumn, three prototype aircraft were ordered, designated Do.19 and Ju.89. On the Junkers, work on the Ju.89 was led by Ernst Zindel, who widely used the experience gained in the creation of the Ju.86. Duralumin was used in the design, and chromium-molybdenum steel was used for loaded nodes. The fuselage was a monocoque square section, reinforced with frames and stringers, with an elliptical fairing on top. The wing consisted of five sections. The center section was carried out in one piece with the fuselage and had five spars. The inner section of the console had five main and two auxiliary spars, and the outer section had four main and three auxiliary. The flaps were of the "Junkers double wing" type and consisted of two sections. The main landing gear retracted hydraulically into the rear of the engine nacelle.
The power plant consisted of either four Junkers Jumo-211A engines or four Daimler-Benz DB-600A - 12-cylinder, liquid-cooled. A crew of nine was envisaged: two pilots, a radio operator, a scorer-flight engineer and five gunners. Defensive armament consisted of one machine gun in the forward fuselage, the same machine gun in the tail mount and cannons in the upper and lower hydraulically controlled double turrets. In the bomb bay, on a vertical suspension, 16 × 100kg or 32 × 50kg bombs could be placed.
The first two experimental aircraft - Ju.89-V1 and V2 were already in a high degree of readiness, when June 3, 1936. Lieutenant General Wefer died in a plane crash. The premature death of the main supporter of heavy bombers led to the arrival of Albert Kesselring to his post, who opposed the construction of strategic aviation at this stage in the development of the Luftwaffe, which was to the detriment of tactical aviation - this was the main reason for the termination of work on the Ju.89 and its competitor Do.19 . However, the insistent demands of the Technical Department, represented by Bomber Aviation Inspector General Kurt Pflugbeil, made it possible to continue work on experimental machines. At the same time, the entire program of the "Uralbomber" was revised. Tsindel had doubts about the possibility of continuing the Uralbomber program, since a revision of the requirements led in November 1936. (just a few weeks before the first flight of the Ju.89-V1) to the emergence of new specifications for the so-called "A" bomber. As a result, the chief designer made a request to use the Ju.89-VЗ units for the manufacture of a commercial transport aircraft. Five months later, the Uralbomber program was finally terminated.
