Is it possible to add 16 more VLS to the deck? Seems like its some more space there. 32 VLS, including 16 atmaca anti-ship missiles would make it in its own class of frigates under 5 000 displacements.
It doesn't need 16 more VLS, if we look at the bay where AShM are stored, 16 more oblique canisters may be placed there if found necessary. But carrying 32 missiles in an open area vulnerable to attacks may not be the good the good idea, however some ships carry AShM in facing configurations.
So in addition to existing 16, either of these may be carried;
24 Cakir missile (assuming 6 missile per spot)
16 Kara Land attack cruise missile
16 Atmaca IIR
24 TRLG-230
Decent amount of kamikaze - loitering munitions from oblique launchers, assuming 16 Kargi's at least.
Also the VLS is a full length version thus Gezgin may be carried in 8, while remaining 8 being spared for quadpacked AD.
Or Gezgin may occupy two facing quad spots and 8 Gezgin + 8 Atmaca might be carried in the AShM bay.
