Ju 87B1

The appearance of the new car was finally formed on ten (according to other sources, fifteen) pre-production Ju 87B-0, which were assembled in the summer of 1938. A second 7.92 mm MG 17 machine gun was installed in the left console. Compared to the Ju 87A, the maximum horizontal speed increased by 30 km / h, and the dive speed increased to 600 km / h.

In October 1938, mass production of the Ju 87B-1 began and the first five machines immediately went to Spain in the Legion Condor. In March 1939, the initial RLM order for the Ju 87B-1 increased from 396 to 964 copies and the two plants producing Stukas, the Weser firm in Berlin-Tempelhof and the Junkers firm in Dessau, were joined by another Weser plant in Bremen- Lemwerder. By the middle of the year, the Ju 87В-1 production rate at the Tempelhof plant (their main manufacturer) reached 60 units per month. Starting from the 697th copy, the Ju 87B-1 began to install a new Jumo 211D engine with a take-off power of 1140 hp. from. with jet-type exhaust pipes, which improved the aircraft's flight characteristics. The general "scoop" still remained. On the B-1, a howling siren first appeared on the left landing gear fairing, which was powered by a two-bladed windmill from the oncoming air flow. On the following versions of the "Things" sirens were already installed on both landing gear. The total number of Ju 87B-1s produced was 800-820.
