Dreadnought supplier contract ended after security reviews

The United Kingdom Ministry of Defence terminated a supplier contract connected to the Dreadnought ballistic-missile submarine programme after security reviews within the Defence Nuclear Enterprise. Officials disclosed the termination in a parliamentary answer concerning a fruitless payment recorded in the 2025–26 accounts, but withheld the contractor’s identity, the work involved, the contract value, and the reason because the programme is classified. The decision concerns the supply chain supporting four new submarines intended to replace the Royal Navy’s Vanguard class. No effect on the construction schedule was publicly identified.
