The Junkers Ju-87 (commonly known as the Stuka) was a single engine dive bomber, whose B (Berta) Variant was the first version used by the Luftwaffe on a large scale during World War 2.
The Berta evolved in an attempt to solve the problems discovered in the disappointing performance of the Anton. The primary difference was the installation of the Junkers Jumo 211 A engine, which was rated at 1,100hp. This gave the Ju 87B the necessary power to be a truly effective dive-bomber. The cowling was redesigned to allow for this installation and included the shifting of several support systems and a larger, rounder radiator bath. Another feature was a complete redesign of the landing struts. Gone were the ungainly trousers and in there place were much more aerodynamically efficient spats. Also introduced was an automatic pull-out device to prevent pilots that blacked out during a being rudely awakened by an untimely impact into the terrain.
Five Ju 87B-1's flew with the Condor Legion and completely eclipsed the Antons performance, thus securing for itself a place in the RLM's tight production schedule.
The Berta was developed into several different versions including the Trop version used by the Afrika Corps and the long ranged R version that was equipped with "strap-on" fuel tanks. The Berta served with distinction in the Polish invasion but revealed severe vulnerabilities a year later during the Battle of Britain, forcing them to be withdrawn to theatres where the Luftwaffe enjoyed some sort of air superiority. The Berta served throughout the war, mainly on the Eastern front and with various airforces, including the Slovakian, Romanian, Hungarian and Italy's Regia Aeronautica.
The Berta was used as the basis for the C variant which was being developed as a carrier based dive bomber. The C variant was cancelled when it was realized that the Berta's airframe was obsolete.
