British steel capacity and future Royal Navy ships

How will the closure of major British steelmaking capacity affect the Royal Navy?

The Navy can continue importing suitable steel, but rebuilding domestic warship-grade capacity requires explicit procurement policy, investment, and higher cost.

Recent Royal Navy ships contain limited British steel because domestic works no longer reliably supply the required hull grades and acoustic characteristics. Port Talbot's move towards electric-arc recycled steel is ill-suited to those requirements, while the Scunthorpe works have suffered prolonged underinvestment. British shipbuilders therefore already source some warship steel from France and Sweden. Britain retains notable expertise in submarine steels and welding, although that specialist capacity also has limits. A government that wants British steel in British-built ships must make origin a procurement criterion. Shipbuilders can then make the necessary investment, but the government should expect to pay for rebuilding the capability.
