The UK’s Submarine Delivery Group, part of the Defence Nuclear Enterprise, has moved additive manufacturing from experimental tool to frontline maintenance capability, deploying on-site 3D printing workshops at HM Naval Base Clyde and establishing a dedicated team to reduce the supply chain delays that keep submarines alongside longer than necessary. The SDG Additive Manufacturing team, established in February 2024 within the Platform Equipment Delivery Team, works with QinetiQ, the SDG Design Authority, and in-service teams to identify manufacturing solutions when components are unavailable or lead times are too long. A Market Access Cell manages incoming demand signals from ship’s staff and joint planning teams, triaging requests and coordinating the fastest route to a replacement part.
