Modelkeenfan Posted December 25, 2020 Share Posted December 25, 2020 Hi all Does anyone know if SU-25A frogfoots were equipped with exhaust cooling tubes inside the engine nacelles with the large cooling air intakes as a field modification during the Afghan war to reduce their heat signatures to counter the stinger threat? Or was it done as a field modification only to T8s that were sent to Afghanistan? Any info appreciated Quote Link to post Share on other sites
harvy5 Posted December 31, 2020 Share Posted December 31, 2020 No, there were none in Afghanistan. The R-195 engines were used only on the T8-15 prototype, presented at the Paris air show in 1989, and on the BM version. The last few Su-25s produced also had the ability to use these engines. But not used, and the rebuilding of the older version was abandoned Quote Link to post Share on other sites
Modelkeenfan Posted January 15, 2021 Author Share Posted January 15, 2021 Thanks for the info. I asked because in my squadron signal book "SU-25 Frogfoot in action"publication 129, it shows a picture on the top left of page 11 showing the rear of the right hand engine with the additional chaff/flare dispensers on the top of the engine nacelle with the "stove pipe" looking cooling tube fitted and the photo caption reads - "Because of the threat from stinger missiles in Afghanistan, the Frogfoot A was modified to both reduce the IR signature and to provide some self defence from these missiles. A large cooling air intake was installed on the upper rear engine nacelle along with a smaller intake at the bottom of the nacelle. A cooling tube was installed in the exhaust stream and ASO -2V chaff/flare dispensers were fitted to each side of the nacelle." Son fact its a picture of a T-8-15 then? Not a SU-25 Frogfoot A as it states? Quote Link to post Share on other sites
