Britain is preparing to unveil plans for a large missile project intended to strengthen NATO deterrence against Russia. According to the reporting, Prime Minister Sir Keir Starmer is expected to announce on Wednesday that the UK will work with roughly a dozen NATO allies on developing “deep strike” missiles. The program is described as having an estimated cost of about £40 billion. The intent is to deter Russian aggression, with the missiles characterized as having the capability to reach targets such as Moscow, based on the description provided in the source. The reports frame the initiative as part of broader NATO defense planning rather than a standalone UK-only procurement. Beyond the stated scale, participating nations, and the deterrence objective, the source does not provide additional operational details such as deployment timelines, specific missile systems, or governance arrangements for the multinational effort. The announcement is therefore focused on setting out the concept and cooperation scope for the proposed NATO-aligned missile capability.
