Talwar frigates are multirole . It come handy containing pak navy. Easy maintenance and cheap to operate. It more like specifically for handle any operation in arabian sea. On other hand shivalik are for broader threat in eastern theatre.
Talwar is an Overkill for Pakistan. Khoras and Khukris are enough. Armed with Brahmos, Shitl SAM (Had a Tu 22 Kill in Russian-Georgian War) Range 50 Km, 1 ASW /AWEC Helo, RBU 6000, Torpedos. Can work as a One Man Ship. That's the Best Part.
P17A is far more superior in Weaponry then most European frigates out there.we certainly go for french des. we have to pay price of carrier.
Russia itself launched Gorshkov Class - It's First Capital Warship in 25 Years.No to rus des. It is better to have kolkatta des. Yes time matters.
Rajput needs upgrades.
Rajput already went through the upgrade with Brahmos and New EW suite.
Rajput should be sold to Vietnam after P15Bs start arriving.
