A major aerospace contractor has received an expanded agreement to continue production and sustainment of submarine-launched ballistic missiles central to US and UK nuclear deterrence. The arrangement covers missile manufacturing, upgrades, and long-term support, extending the program into the next decade. First deployed in the 1990s, the system has undergone steady improvements to guidance, propulsion, and reentry components, maintaining high accuracy and reliability. The contract also supports allied use, reflecting the deep defense ties between Washington and London. Both nations plan to keep the missile in service through the 2040s, aligning it with the introduction of new submarine classes and reaffirming its central role in nuclear strategy.
