the question is:
the question is - is turkey able to build smoothbore tank guns on her own? instead of using the 120mm/L55 for the Altay - and if not - is turkey working on something similar?
there were Rh prototypes for a 140mm tank gun:
"The cannon should have a muzzle energy of 20 megajoules (MJ), which would have meant a doubling of the muzzle energy compared to the L / 44."
turkey shouldn't use kanons that are slowly becoming obsolete...
