CSC set to supply gas cylinders for Astute nuclear submarines

Chesterfield Special Cylinders (CSC) has won a £2m contract by BAE Systems Submarine Solutions to provide high-pressure gas cylinders for the Royal Navy’s sixth Astute-class nuclear submarine — the HMS Agamemnon.

The cylinders are critical to a number of operations within the Astute vessels, including breathing gas storage, hydraulic and valve actuation back-up, ballast operation and missile launch systems.

The order takes the value of CSC’s contracts for the Astute-class submarines to more than £12m, having already supplied gas and oxygen systems for the Astute and Ambush submarines, which are already in the water, and the next three (Artful, Audacious and Anson) being built by BAE in Barrow-In-Furness. A seventh and final Astute, Ajax, is due to enter service in 2024.
