The United Kingdom has ruled out any possibility of replacing its current nuclear system with French technology, reaffirming its commitment to the Trident II D5, supplied by the United States.
The statement was made by Defence Minister Luke Pollard in response to questions about potential cooperation involving the French M51.4 missile.
Although London and Paris maintain close collaboration in nuclear research and technology — strengthened by agreements such as the Teutates Treaty and the recent Northwood Declaration — the British government made it clear that this partnership does not include the development or adoption of a joint strategic missile system.
Currently, the United Kingdom operates the Trident II D5 on Vanguard-class submarines, with plans to replace them with the Dreadnought class in the next decade. France, in turn, uses its own M51 missiles on Triomphant-class submarines, investing in more advanced versions to expand range and penetration capability against enemy defenses.
Despite technological and operational differences, both systems fulfill the same strategic role of continuous nuclear deterrence. In the British case, Trident stands out for its robust testing record, with more than 200 launches and a success rate above 90%, maintaining its reputation as one of the most reliable systems in the world, even in light of some recent isolated failures.
