In the late 30-s much work was underway on designing a new heavy long-range bomber for the Red Army Air Force. In this connection there arouse an urgent need for an escort fighter having the compatible range and speed that only a twin-engined aircraft design could provide. The development of such an air vehicle was entrusted to the design office headed by V.M. Petlyakov. The task was advantageously realised. The aircraft turned out to be a success. It contained a good deal of unique technological improvements for the USSR aviation. At the stage of evaluation high performances of the plane required a re-designing of the concept into the high -speed dive bomber.
That's how the dive bomber Pe-2, the most mass produced 2E aircraft (more than 11000 pcs. were manufactured) came into being. It left vivid traces on the history of WW-II.
