The Royal Navy and RAF have teamed up with the US to destroy and sink a warship in the first exercise of its kind in 18 years.
Type 23 frigate HMS Westminster, a Wildcat helicopter and three RAF Typhoon were involved in the live-fire practice using high-powered weaponry to sink the decommissioned frigate USS Boone.
The exercise, which took place in the North Atlantic, was the first time in 18 years that the Royal Navy had targeted a real warship and the first time the Typhoon had been used to drop live ordnance on a warship at sea.
Commander Ed Moss-Ward, Commanding Officer of HMS Westminster, said: “Atlantic Thunder has demonstrated that UK and US naval and air forces can work together to deliver an end-to-end kill chain against a maritime target at long range.
“The firings have supported the development of the Royal Navy’s targeting and weapon capabilities, and afforded opportunity to conduct realistic training to validate tactics and operating procedures.”
A Navy spokesman said: “It was a rare live test of complex weapons against a realistic target far out to sea and tested the power and accuracy of naval and air forces, giving allies real-world experience of hitting targets at sea from long range and proving the capability of several advanced warfighting and targeting techniques.
“Type 23 frigate HMS Westminster fired two Harpoon anti-ship missiles at the same time as a US P-8 Poseidon patrol aircraft launched one of its own – 660kg of high explosive striking ex-USS Boone simultaneously.
“This was the first firing of the Fleet Air Arm’s new anti-ship weapon against a realistic target at sea – to this point Martlet had only been used against purpose-built targets.
“The Wildcat’s crew stayed airborne and used the on-board laser-targeting pod to guide in a Typhoon fighter from 41 Squadron RAF to launch Paveway IV precision-guided munitions against the target.
“This was the first time an RAF Typhoon had dropped live ordnance onto a warship used as a maritime target and the first time a Royal Navy helicopter had guided the Paveway IV on to its bullseye.”
The Navy spokesman added that all toxic materials and pollutants had been removed from the USS Boone, which was retired in 2012, prior to it be used as a target.
