There will be Greek AH-64 and OH-58.....with Spike NLOSAgain in my humble opinion, FACs need more reliable defence system such as CIWS, due-to their consistently attack missions. But I've no idea , at the rear of the FAC , if CİWS could be efficient. You might be right with RAM but Gökdeniz CIWS seems more solid and reliable to me.
On the other hand I assume Turkish Navy prepares itself for threats just come from Greek Navy. So all countermeasures are against Greek subsonic Harpoon and Exocets. What if Russian supersonic missiles were used against Turkish FACs?
We need air defence missiles against helos and some fighter jets
