With HMS Agamemnon, the Royal Navy’s sixth Astute-class nuclear submarine, currently under construction in the UK, Chesterfield Special Cylinders (CSC) has secured a £2m contract to supply high-pressure gas cylinders for the project.

HMS Agamemnon is currently under construction at Barrow-In-Furness by BAE Systems Submarine Solutions.

CSC had already supplied gas and oxygen systems for the first two Astute Class submarines already in the water and with the contracts already secured for the next three being built, this new award for the sixth submarine takes the value of CSC’s contracts for the Astute Class submarines to over £12 million.

A seventh and final Astute, Ajax, is due to enter service in 2024.

CSC has been supplying the Royal Navy with high-pressure gas storage cylinders for ships and submarines since the 1930s. Its reputation for safety-critical systems is second to none and this contract further cements its standing as a leading supplier to BAE Systems. The cylinders that CSC is supplying for the Astute submarines are critical to a number of vital operations within the vessels, including breathing gas storage, hydraulic and valve actuation back-up, ballast operation and missile launch systems.

Sales manager for CSC, Lee Lawrence, explained, “This contract is testament to the strong, well-established relationship forged over many years between ourselves, BAE Systems and the Royal Navy.”

“It underpins the confidence that BAE Systems and the Royal Navy have in the safety critical products CSC has supplied for the previous five Astute submarines,” he added.
