Odessa I specifically quoted your post. Su-57 creates an informational noise for you. Indeed, the combat power of these patrol ships is not great unless they receive missile weapons. This small armored boat is capable of launching 2 missiles, sending a corvette to the bottom. Soon they will be re-equipped with new missiles, which have a larger caliber (170mm). another launch range (10 km), which will not allow entering the AK-630 firing zone (7 km), and the launch of 2 missiles is already capable of sinking the frigate.
