A modern Royal Navy fast attack craft

Is there a role for a modern fast attack craft in the Royal Navy?

Yes, especially for inshore security and escort, but current budgets make it a lower priority than existing programs.

The proposed craft is fast, agile, and based conceptually on the Combat Boat 90, potentially without an onboard crew. Naval Strike Missile and gun armament would give it utility in confined waters. Plausible roles include inshore patrol, close security in places such as the Strait of Hormuz, and landing-craft escort. The obstacle is whether the capability offers enough value to displace another item in a constrained budget.
