AK-II will proceed at its own pace. It is a separate program, VT-4 is a seperate acquisation.
With respect to the question of the acquisition of VT-4 as to block approach like JF-17, I can't comment as to what the future holds, but as of yet the Platform will be more or less the same with very minor additions-unless anything revolutionary comes into play-The main emphasis is on Less diversity of platforms in order to maintain the logistical support necessary for operational efficiency. That's how the approach is shaping up.
P.S In my personal opinion-I wish The Turks could have matured the Altay and pressed into Production by the time this tender was shaping up. But have no doubt the VT-4 is a beast with an exceptional situational awarensss and a deadly armoured punch.
My main concern is the survivability and amour can it survive modern ATGMs allowing it and the crew to fight another day? Is it on M1A1 1st armor level?
