The Royal Navy’s fifth Astute-class nuclear submarine was officially named HMS Anson at a ceremony today.

A total of seven Astute-class submarines equipped with periscopes that do not penetrate the hull are planned to be built. Using an advanced video system in the control room, the submarines do not need a second nuclear refuelling during the service period. Platforms that can dive to a depth of 300 meters can be ready for operation in about five hours.

The 97-meter-long submarines, which have low acoustic performance, can be equipped with the UGM-109 Tomahawk cruise missile.

HMS Anson, which is under construction, is planned to take sea tests in 2022.
