The Royal Navy has successfully demonstrated its new long-range missile capabilities by sinking a decommissioned U.S. Navy frigate during a recent training exercise in the North Atlantic. The event, conducted off the northwest coast of Scotland, highlighted the navy’s ability to operate alongside NATO allies amidst rising global tensions.

HMS Portland launched a naval strike missile at the USS Klakring, achieving a direct hit on the retired warship. The missile, capable of striking targets over 100 miles away while evading radar detection by skimming close to the sea surface, was part of Exercise Atlantic Thunder. In addition to the missile strike, HMS Portland’s Wildcat helicopter fired Sea Venom missiles during the exercise. The U.S. Navy also fired a missile from USS Paul Ignatius, targeting the vessel from a separate position to simulate realistic combat conditions.

Prior to the exercise, the USS Klakring underwent thorough cleaning, and environmental checks were conducted to ensure no marine mammals, such as dolphins or whales, were present in the area. The operation was deemed a success by both navies.

Lieutenant Commander Louise Kirkaldy, HMS Portland’s principal warfare officer, described the event as a “significant milestone” for the Royal Navy, underscoring its preparedness for current and future security challenges. Petty Officer James Kenyon, an above-water warfare specialist involved in the exercise, called participating in the high-profile operation the highlight of his career.

The demonstration also served as a reminder of the Royal Navy’s increasing vigilance in response to heightened international activity. In August, the navy monitored a group of Russian warships transiting from the North Sea toward the English Channel, reflecting ongoing maritime security concerns in the region.
