The Royal Navy (RN) has a Naval Rapid Reaction Force stationed in the Eastern Mediterranean centered around the helicopter carrier HMS Illustrious along with two frigates and a yet to be identified nuclear-powered Trafalgar class submarine.
The RN's Trafalgar subs have the Raytheon Tomahawk Block IV land-attack cruise missiles as standard weaponry. The US Navy's 6th Fleet headquartered in Naples, Italy, has already stationed four Arleigh Burke-class guided missile destroyers off the coast of Syria. Each destroyer has the capability of unleashing a maximum of 100 cruise missiles each against any given target.
