The first firings of the Royal Navy’s new air missile defence system have been successfully conducted off the Scottish coast.

The Sea Ceptors, which can intercept and destroy enemy missiles travelling at supersonic speeds, were fired from Type 23 frigate HMS Argyll The system, which is to be used on the new aircraft carriers, uses a missile capable of reaching speeds of up to Mach 3. three times the speed of sound.

It will be able to deal with multiple targets at the same time, protecting an area of around 500 square miles over land or sea.

Harriett Baldwin, minister for defence procurement, announced the successful firings during a visit to defence company MBDA in Filton, Bristol.

“Sea Ceptor will protect our interests against threats both known and unknown,” she said.

“It will launch from the Royal Navy’s new Type 26 frigates as they keep our nuclear deterrent submarines and the UK’s two new aircraft carriers safe on operations around the globe.

“Sea Ceptor supports 600 UK jobs and is yet another example of how our rising defence budget is being spent on cutting-edge kit to help our Armed Forces meet future threats.”

Sea Ceptor is being fitted to replace the Sea Wolf system on the Type 23 frigates.

The air defence system will be used on the new Type 26 frigates and Land Ceptor, which will replace Rapier for the British Army.

It uses MBDA’s next-generation Common Anti-air Modular Missile (CAMM) as well as innovations in radar and datalink technology.

Commander Toby Shaughnessy, the Commanding Officer of HMS Argyll, described the system as an “exciting upgrade” adding: “Sea Ceptor is an impressive and innovative system, demonstrating that the Royal Navy is at the cutting edge of technology."
