The nuclear submarine has returned to Devonport for the final time before her decommissioning.
The Royal Navy say that, as is the tradition of a ship sailing into her home port for the last time, the submarine proudly flew her paying off pennant and a number of her crew ‘went up top’ to line the casing.
According to a Royal Navy news article that can be found here:
“HMS Trenchant is a Trafalgar-class nuclear-powered submarine, she was launched in 1986 by war hero Vice Admiral Sir Arthur Hezlet – he was the commander of the original HMS Trenchant submarine during WW2. Together with the Astute class, HMS Trenchant make up the Royal Navy’s hunter-killer submarine force.
During her 35-years on patrol there have been many highlights of her service, two of which have been her ice-patrols. In 2016 the boat punched through the ice and emerged on the surface of the Arctic Ocean. This marked nearly a decade since a British boat had carried out this manoeuvre, re-generating the Submarine Service’s under ice capability.
In 2018 in the harsh environment of the North Pole HMS Trenchant broke through the ice in an exercise with the US Navy, literally sitting on top of the world.”
HMS Trenchant is the oldest submarine in the Royal Navy fleet.
