The United Kingdom’s new Astute-class submarine HMS Anson has carried out its first trim dive, a procedure in which numerous tests were conducted to verify and set up the vessel’s accurate weight and center of gravity.
A Royal Navy crew tested the safety and stability of the 8,157 ton, 318.2-foot-long attack submarine at Devonshire Dock in Barrow-in-Furness in the northwestern English county of Cumbria.
