Imagine having 4/8/whatever USV's around TCG Anadolu (or another ship) armed with Atmaca's or aa missiles or torpedoes, or just using jammers 100 km away from the ship. It'll change the playfield considerably, imo.
I think the primary thing that will make these USVs dangerous is not the AShMs but the benefits they will provide especially in terms of ASW capabilities and ISTAR-EW. These boats can even be given low-altidude air defense capability. Here we can give dozens of different examples of payloads. Many of them can be seen as asymmetric boats, but if we consider that they will operate as a group/swarm with a common command, they are essentially like a distributed/peripheral missile/patrol corvettes, which makes them even more dangerous.
The motherships will have an army of protection above the water. A lot of attack boats in swarms that will give you trouble before they reach the mothership. It's not enough to neutralize one, you can't eliminate the advantage of the mothership until you neutralize all of them. While the attacking ship is dealing with these boats, its exact coordinates and maneuvering envelope are fully revealed, which means a missile salvo from the mothership or a USV outside the swarm in a few minutes. Of course, naval warfare is not as isolated as this, it is much more complex, but basically what I am saying is that it is inevitable that we will see these mothership capabilities and even navy trends directly dedicated to this purpose in the future. Not only from the Turkish navy but all over the world. And luckily we are one of the first countries to start this concept.
Although USVs are not very cheap systems, it is acceptable to lose them at a point of hot contact. But the loss of a navy ship would destroy the morale of any country.
