A major milestone has been achieved in the life of the fifth Barrow-built Astute-class submarine. Under the control of its Royal Navy crew, Anson completed its first trim dive in the town’s Devonshire Dock. The operation saw Anson submerge completely beneath the surface of the water while the crew tested onboard systems. This successful exercise proved the safety and stability of the 7,400-tonne, 97 meter-long attack submarine. A ‘trim dive’ is done to complete several tests. The most important is to help engineers establish the vessel’s center of gravity and precise weight. More than 60 crew members were on board as part of the exercise, which saw tonnes of ballast taken aboard to assist in testing the vessel’s stability. The Company employs around 10,000 people in its Submarines business, with the majority based at its shipyard in Barrow-in-Furness, accounting for approximately a quarter of the local working population.
Commanding Officer of Anson, 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.”
BAE Systems Submarines Astute Programme Director, John Moorby, said: “The successful trim dive of Anson is a significant milestone in the submarine’s test and commissioning phase. It demonstrates the continued successful collaboration between BAE Systems, the Submarines Enterprise, and our suppliers on delivering this national endeavor for the UK Royal Navy.”

Anson was officially named in December 2020 and launched in April 2021. HMS Astute, HMS Artful, HMS Ambush, and HMS Audacious are already in service with the Royal Navy. The sixth and seventh Astute submarines, Agamemnon and Agincourt, are at different stages of construction at the Barrow shipyard. As well as the Astute Class, BAE Systems is delivering the Dreadnought submarines for the Royal Navy and undertaking early phase concept design work on the replacement for the Astute class.
In 2020, BAE Systems spent over £80 million with more than 100 suppliers in Cumbria, supporting 1,380 jobs in the region’s supply chain. The Company’s significant UK footprint across more than 50 sites and extensive supply chain means it supported 143,000 jobs across the country and contributed more than £10 billion to UK GDP, equivalent to 0.5% of the domestic economy. To ensure a robust pipeline of talent for the future, the Company invested £93 million in skills, training, and development activities in 2020. That included more than 2,000 apprentices and nearly 600 graduates in training across a wide range of roles from electronics and electrical, structural, software, and research engineers, to manufacturing, operations, and project management. Continuing its support for young people, this year BAE Systems will recruit almost 1,700 apprentices and graduates across the country – 25% up on last year and the largest intake it has offered in a single year – including more than 500 in Barrow-in-Furness.
