U.S. Strikes British Air Defense Network in Opening Salvos of Operation Albion Anvil: Undersea Clashes Erupt in North Atlantic as UK Declares State of War

At 04:12 GMT on Monday, 16 February 2026, the first long-range kinetic strikes against the British mainland since 1945 crossed the line of departure. Staging from launch baskets northwest of the Faeroe Islands and the central Norwegian Sea, B-52H Stratofortresses from the 2nd Bomb Wing, B-1B Lancers from Dyess Air Force Base, and F/A-18F Super Hornets of Carrier Air Wing 1 aboard the USS Harry S. Truman released an opening salvo of 148 AGM-158B JASSM-ER cruise missiles and AGM-88G standoff anti-radiation weapons targeting the United Kingdom's integrated air defense network.

Inside the subterranean operations room at RAF Boulmer in Northumberland, radar operators watched screens fill with dozens of high-speed inbound tracks emerging beneath the radar horizon. Royal Navy Type 45 destroyers HMS Defender and HMS Diamond, operating on war-alert stations in the Firth of Forth and the Humber estuary, fired multiple salvos of Aster 30 interceptors via the Sea Viper air defense system, while land-based Sky Sabre (CAMM) missile batteries engaged missiles descending across the Scottish coast. Royal Air Force Quick Reaction Alert (QRA) Typhoon FGR4s scrambling out of RAF Lossiemouth and RAF Coningsby brought down nineteen cruise missiles with Meteor and ASRAAM interceptors. In total, allied air defenses destroyed 84 incoming munitions. However, 64 missiles penetrated the screen: primary 3D radar installations at RAF Buchan in Aberdeenshire and RRH Benbecula in the Outer Hebrides were obliterated, communications relay masts across the Pennines were brought down, and runway infrastructure at RAF Leeming suffered heavy cratering. Boulmer's surface transmitter masts were destroyed, though its hardened command bunker remained operational on auxiliary feeds.

Beneath the surface of the North Atlantic, Task Force 84's opening phase of the counter-CASD campaign—the operational attempt to locate and neutralize Britain's Continuous At-Sea Deterrent—erupted into a lethal submarine engagement. Twelve U.S. fast-attack submarines (Virginia- and Los Angeles-class) sweeping south through the Faeroe-Shetland Channel and Rockall Trough collided with a joint British and French hunter-killer cordon. Two hundred miles west of the Outer Hebrides, the British submarine HMS Ambush (Astute-class) and the French nuclear attack submarine Suffren ambushed a U.S. patrol line. The Los Angeles-class fast-attack submarine USS Newport News (SSN-750) was struck by a British Spearfish heavyweight wire-guided torpedo; after suffering catastrophic flooding in its aft engineering compartment, the boat executed an emergency ballast blow to the surface and was scuttled by its surviving crew before capture. HMS Ambush sustained heavy propulsion damage from a retaliatory Mk 48 Mod 7 torpedo fired by USS Indiana (SSN-789) and was forced to withdraw under auxiliary electric drive toward Faslane. Crucially, neither of the two Royal Navy Vanguard-class ballistic missile submarines—HMS Vanguard and HMS Victorious—was detected. USSTRATCOM acoustic hydrophone tracking confirmed both boats successfully cleared the continental shelf into deep Atlantic launch sectors, maintaining thirty-two Trident II D5 thermonuclear missiles at sea.

At 11:00 GMT, Prime Minister Sir Keir Starmer addressed an emergency sitting of the House of Commons in London following a three-hour COBRA session. Describing the strikes as "an unprovoked act of war against the British people by a former ally," Starmer formally declared a national State of War and announced the activation of the unified Anglo-French command under the Lancaster House Treaties. In Paris, President Emmanuel Macron addressed the French nation, stating that France considered the attack on the British homeland an attack on Europe's vital strategic security, ordering the aircraft carrier FS Charles de Gaulle and its Rafale M strike group into immediate battle formation alongside the Royal Navy fleet.

In Washington at 18:00 EST, Secretary of Defense Pete Hegseth and Commander of U.S. Strategic Command General Anthony Cotton delivered the classified Phase I SITREP to the Situation Room. Hegseth reported that while northern British early-warning radars were significantly degraded, the opening salvo had consumed roughly 14% of the nation's entire global inventory of JASSM-ER standoff missiles in twelve hours, one attack submarine was lost, and the Royal Navy's sovereign nuclear deterrent remained completely uncontained. General Cotton briefed that U.S. strategic forces remain locked at DEFCON 2, with Minuteman III ICBM wings and the strategic bomber fleet on cockpit alert against potential submarine-launched ballistic missile trajectories.
