A dedicated anti-drone gunship or a mixed escort

Which major navy is most likely to build a dedicated anti-drone gun warship?

The panel identifies none of the three as a likely builder in this scenario and instead describes a mixed escort with increased gun armament.

The question compares the United States, Russia, and China as possible builders of a dedicated anti-drone gun warship. The panel instead considers increased gun armament on existing escort types more likely than a separate pure gunship. Its comparison is Britain's flak-frigate concept, which still combines guns with missiles.
