Well, how is the comparison of Su-25 and Yak-130 operation range and takeoff weight?
was't there some plans to start up the Su-25 prod-line again?
The entire Su-25 fleet is getting upgrades and life-extensions. The trainers are being replaced entirely with new Su-25UBM aircraft. It's unclear whether some of the regular planes are getting replaced also. Honestly I don't see a Yak-130 replacing them anytime soon.
