HMS MERSEY sailed in to London this morning for a five day port visit.
The River-Class patrol vessel, one of the busiest vessels in the Royal Navy's fleet, arrived in to the Upper Pool of London through Tower Bridge at 09:15.
The ship's primary function is to patrol British Fishery Limits and the visit to London will enable a crew change to take place.
The ship's commanding officer, Lieutenant Commander David Gillet commented:
“This visit to London is a low key one on this occasion and a welcome break from significant periods of time spent at sea.”
He added: “Although not able to open to the public during our time in London, we will host a number of pre-arranged tours for interested groups and organisations, including Sea Cadets from around the capital.”
On her inbound journey to London, she passed the Brazilian navy frigate BRASIL which departed under Tower Bridge earlier this morning.
