What is the closest modern coastal-defence ship?

What ship is the modern equivalent of a coastal-defence ship?

The Swedish Visby class is the closest current analogue in this comparison.

The Visby class is the strongest modern candidate for the coastal-defence label. The comparison is functional rather than literal: Visby uses stealth, missiles, sensors, and speed instead of a thick armored belt and heavy guns. Its value is nevertheless tied to operating in Sweden's archipelagos and nearby Baltic waters. The mission can persist even when technology changes the form of the ship.
