During the trim dive, the crew carried out trials of on-board systems to confirm the submarine’s stability and safety.
Anson commanding officer commander David ‘Bing’ Crosby said: “The trim and basin dive is a key step in the commissioning of HMS Anson. This period will enable us to set the boat’s internal weight, prove her water-tight integrity, test sensors and put some of our systems through their tests ahead of sailing for the first time.
“All involved should be very proud. The entire enterprise has again come together to achieve this evolution safely and on time, which is clear evidence of our joint approach and demonstrates what we can achieve when we all pull together.”
