In the US, talked about training on Soviet fighters

US Air Force spoke about training their pilots on the MiG-17, MiG-21, MiG-23

Starting from 1978 and 1988, the US 4477 Squadron ("Red Eagles") of the US Air Force was engaged in familiarizing American pilots with the capabilities of the Soviet MiG-17, MiG-21 and MiG-23 fighters. Approximately 15 thousands of sorties were flown. As reported on the Facebook page of the Nellis airbase (Nevada), the fighters were piloted by almost 6 thousands of pilots. The message is a documentary video.

The training of pilots of the Air Force, the Navy, and the US KMP was engaged in the Constant Peg (a unit in the Red Eagles). The task was learning to control a real Soviet aircraft in a real battle. Such information provided by Constant Peg's boss at 1979 - 1980, Earl Henderson, is quoted by The National Interest.

The documentary film states that the Soviet aircraft themselves and their individual elements were delivered to the United States from Vietnam, Israel, and Afghanistan.

According to the American magazine, the work of "Constant Peg" had a positive impact on the development of technology. As told by John Manklark, the head of the "Constant Peg", the CIA provided for the study an automatic machine, with the help of which the dipole reflectors and infrared traps that Su-25 had were dropped. This attack aircraft was shot down in Afghanistan. The American repairmen worked with him, and the machine gun was installed on the MiG-21. Manklark said that the Americans were later able to create an improved homing head for the AIM-9 Sidewinder guided missile.

In April last year, a publication appeared in Task & Purpose, from which it appeared that the Americans managed to ensure that the fifth generation Lockheed Martin F-35 Lightning II multi-purpose fighter-bomber was unobtrusive using Russian DNA.
