The Junkers Ju 188 was characterised by its large, bulbous “glasshouse” of a nose and its new pointed-tip wing spanning 22 m. In 1941 the first major version, the Ju 188E-1, entered production. Powered by two BMW 801G (1250kW) radial engines and carrying up to 3 tons of bombs. Ju 188E was in operational service the following year together with its reconnaissance counterpart, the Ju 188 F, which was similar. Following these came the Ju 188A, which had been awaiting the availability of the powerplant originally intended, the 1290 kW Junkers Jumo 213A. Apart from the engine change and a reduced bomb load, the Ju 188A-1 and A-2 were largely similar to the E series although slightly faster. An experimental bomber development of the A model was the Ju 188C, featuring a remote-control tail turret containing two 13 mm. MG 131 machine guns; although this model did not achieve production status, a development of it was built in small numbers as the Ju 188G. The Ju 188D was a fully-armed reconnaissance counterpart to the Ju 188A bomber. Ju 188H a further reconnaissance project, based on the Ju 188 G, which did not materialise. Other developments that were soon abandoned were the Ju 188M, for long-range reconnaissance, the night fighter Ju 188 R and the photographic Ju 188 T. The last planned versions, the Ju 188 S and T, was a fast, high-altitude bomber/intruder with quite an impressive performance. Possessing a pressurised and more streamlined crew cabin, and powered by two 1510 kW Jumo 213 E-1 engines, the Ju 188 S had a service ceiling above 11500 m and was unarmed, relying on its high speed (nearly 690 km/h) to evade pursuit.
Ju 188 was never to replace the Ju 88. Some 1234 units were produced, seeing action in Europe, the Mediterranean Sea and Eastern Front, but they did not make a significant impact on the war.
