As the Royal Navy's new air missile defence system enters into service, Forces Network takes a look at what it can do.
Sea Ceptor will be deployed aboard the Navy's Type 23 frigates and is said to be able to deal with multiple targets at the same time, protecting an area of around 500 square miles over land or sea.
But what about the new Sea Ceptor missiles?
Brought in to replace the existing Sea Wolf missiles on the Type 23 frigates, they can travel much further before hitting a target.
Sea Ceptors are described as having a range 'in excess of 25 kilometres (15.15 miles)', as opposed to the 1–10 km of their predecessors, although IHS Jane's reports that trials have a shown a capability of up to 60 km.
Speed remains the same, at 1,020 m/s (3x speed of sound), although a high rate of fire allows attacks against multiple simultaneous targets, while mid-course guidance via a datalink gives the ability to hit targets, not in the line of sight.
Sea Ceptor missiles, which were fired for the first time in successful trials last year, will form part of the protection for the new aircraft carriers, protecting an area about 500 square miles over land or sea.
The missiles, which can intercept and destroy enemy missiles travelling at supersonic speeds, can also be packed tightly, with up to four taking up the space taken by one Sea Wolf.
The system was launched from HMS Argyll, off the coast of Scotland, in September 2017.
The Commanding Officer of HMS Argyll, Commander Toby Shaughnessy, described it as an "impressive" system at the time. He said:
"This is an exciting upgrade in capability and a great opportunity for HMS Argyll to demonstrate what the missile system can do to protect our ships from future threats.
"Sea Ceptor is an impressive and innovative system, demonstrating that the Royal Navy is at the cutting edge of technology and working hard to keep Britain safe."
"I am immensely proud of my ship's company and the work they put in to make this test firing possible."
The system is designed to provide the Royal Navy with an improved shield against airborne threats such as the new generation of supersonic anti-ship missiles, fast jets, helicopters and unmanned aerial vehicles.
Sea Ceptor supports around 600 UK jobs in locations across such as Stevenage, Filton and Bolton.
Richard Smart, Director Weapons for the MoD’s procurement organisation Defence Equipment and Support, said: “Sea Ceptor’s entry into service with the Royal Navy is a significant milestone, a massive achievement for everyone involved and a proud moment for the team.
“It’s really exciting to be delivering a new capability that will form part of the protection for the new aircraft carriers and will help to keep our service personnel and our country safe.”
