 Another major factor in the development of modern Russian aircraft was technology obtained from the Germans after the end of World War II.Since most of the Axis powers were in no condition to repay the billions of dollars that they supposedly owed, the Soviets deployed "trophy brigades", whose task it was to confiscate all equipment, materials, and technology that would be of scientific use to the USSR.Siddiqi points out that the Soviets obtained models of multiple jet fighters, jet engines, and a wealth of technical information concerning equipment related to aviation.
