About the book: 2005 / The most popular model of attack aircraft was the Il-2 type 3 (also known as the Il-2M5). It was created on the basis of the two-seat Il-2M, and the most noticeable difference from its predecessor was the new wing, the sweep of which was increased to 15 degrees (the so-called “arrow” wing). This made it possible to improve the alignment of the aircraft, which had deteriorated significantly after the installation of the second cabin, which had a positive effect on its longitudinal stability. This modification was proposed by the OKB in May 1943, and on November 9, the prototype, built on GAZ No. 18, successfully completed tests at the Air Force Research Institute. At the end of 1943, production cars began to roll off the assembly line..
