Erdoğan is the top asset Turkey has and need to be protected with our top military capabilities.
The region is a also Turkey's southernmost point with borders with hostile Greece and their masters crowding. The presence of military ships around the place is a show of muscles as well.
I would send our top frigate donned with our top capabilities when we have one.
Tell me the difference which an Ada-Class + Submarine could provide compared to a B-Class + some boats.
In other words, if we can't put the ship in a mission to defend a bigger portion of the coast, what is point of locating in a small narrow bay which it can not use the sonar or the radar effectively, how could it actually protect Erdoğan?
Talking about the Greek threat ( the point i have expected you to draw the most) the ship then makes more sense at an outpost , at the place it used to be deployed before Erdoğan did request it to be in bay. The ship makes more sense out of the bay standing in somewhere where it can fully use its sonar, radar and weapon systems freely. Also everybody knows Greeks won't launch a massive attack on location of Erdoğan, but rather some insurgents or terrorists, which in this case the frigate or the corvette makes no use.
Moreover , did you also know he did asked to board some security personnel on corvette and disabled the major weapon systems (fore cannon, missiles, main radar) and kept it disabled throughout the stay? you won't read this in news too. Then how did exactly this corvette served the protection purpose except of "displaying" power merely with allowing to operate the RCWS and LPI radar?.
Turkey >>> Erdoğan, if you can't project the earlier, you can not protect the latter. Get an arleigh burke to protect erdoğan, if its mission is set to protect only him the ship will not able to defend him at all if the surrounding is infiltrated.
Area denial is set at frontiers of the sensitive target, not at the whereabouts.
