History
Conceived in 1935 in response to an official requirement for a high speed medium bomber, the Junkers Ju 88 was to become the most versatile and widely produced German bomber of World War II. Although far from being the only German aeroplane to perform tasks for which it was not originally intended, few were “misemployed” with such success. The prototype Ju 88 V1 dew just before Christmas 1936, only eleven months after design work commenced, being powered by a pair of 900 hp Daimler-Benz DB600 inline engines in annular cowlings. The next year or two saw the completion of further prototypes and as with many other Luftwaffe aircraft of this period — a World record or two by the new aeroplane. Production of the first bomber series commenced in, 1938, and Ju 88 A-l, together with the few A-0 pre-production machines, were in service at the outbreak of war. The Junkers Ju88 A-1, the generally similar Ju88 A-2 and the Ju88 A-3 trainer all had a wing span of 18,25 m but this and several other details were modified, in the light of operational experience, in the Ju 88A-4. The span was increased by 1,8 m, considerable extra gunnery was installed, the bomb load was almost doubled. Many later A sub-types were completed, including the A-5 (produced before the A-4 but having the same wing and bomb load), the A-8 with balloon cable cutter, the A-12 dual control trainer, the A-13 ground attack and the A-17 torpedo bomber. Parallel with production of the A series, Junkers developed the Ju 88B around a pair of Jumo 213As; this series did not achieve full production, though the new nose of the B-1 was reflected in the tater Ju 188, for which another B sub-type acted as prototype. In order to maintain performance of the Ju 88 against that of later designs, Junkers engineers began an extensive reorientation in the middle war years, from which emerged the Ju 88S bombers. Powered by two BMW 801G radial engines of 1700 hp each, the S-1 featured a smoothly rounded nose, no gondola and drastically reduced bomb load and defensive armament. Junkers Ju88 S-2 and S-3 were generally similar except for engine and gunnery changes and a bulged bomb bay in the S-2. Altogether more than 9,000 bomber versions of the Ju 88 were built.
Parallel with the development of the Junkers Ju 88 as a medium bomber, the type was also being adapted to a variety of other roles, particularly those of night fighter, close support and reconnaissance. Approximately 6000 non bomber versions of the Junkers Ju 88 were built, and the length and diversity of this aeroplane’s career make an interesting comparison with the British de Havilland Mosquito. The first Junkers Ju 88 fighter to enter series production was the Ju 88C, comparable with the A bomber and powered by Jumo 211 inline or BMW 801 radial motors. Junkers Ju 88 C-1 featured the shorter span wing of the early Ju 88 A, but from the C-2 onwards the extended wing of the Ju 88 A-4 was employed. The early Ju88 C carried a crew of three and an armament, in a solid nose, of three 7.9 mm. machine guns and one 20 mm. cannon, with two further 20 mm. cannon in a detachable mounting below the nose. From the Ju88 C was developed the Ju 88G, a specialist night fighter carrying an additional crew member, which entered service in 1944. Another parallel to the Ju 88 A-4 bomber appeared as the long range reconnaissance Ju 88D-1, with fuel and cameras in the bomb bay and further fuel in undenving drop tanks. Altogether, nearly 2000 Ju 88 D-1, -2 and -3 aircraft were built. Another long range model was the Ju 88H, both the H-1 (reconnaissance) and the H-2 (fighter). Several Ju 88H aircraft ended their days as the lower half of a Mistel composite, with a Bf 109 or Fw 190 fighter on top of the fuselage. The ubiquitous Ju88 A-4 lent itself to yet another specialised development in the Ju 88P anti-tank aircraft which carried a heavy calibre cannon (two smaller ones in the case of the Ju88 P-2) in a special housing under the fuselage. The final photographic reconnaissance variant, the Ju 88T, was a development of the S bomber.
Total production: 15 183.
