11/27/21 Originally made for DCS 1.5 by Flanker. Modified to 2.5.2 in 2018 by ac5. Modified to 2.7+ by Krasniye in 2021.Updated to DCS 2.9 in 2023. 
Some textures were broken and had to be used from the default English cockpit which is why this is more of a lightly worn or refurbished cockpit instead of a factory new one. 

Shoutout to Enigma and his great new Cold War server for getting me back into the 21 and inspiring me to update this mod.
