The government takes the security and resilience of critical transport infrastructure extremely seriously and has a robust security regime to tackle the range of threats the UK faces.

We work with the National Protective Security Authority, National Cyber Security Centre and across government to advise owners and operators of transport infrastructure on how they can protect themselves against sabotage. The Department will continue to monitor and mitigate existing and emerging threats across the whole transport sector, working with partners across government, internationally and with industry.

The UK has one of the most robust aviation security regimes in the world. We continue to work with partners across government, internationally and with industry and will continue to monitor and mitigate existing and emerging threats to the transport sector.

In her speech on 9 December 2025, to mark the centenary of the Locarno Treaty, the Foreign Secretary highlighted the significant security challenge Russian interference poses to the UK and our partners. Cdr Dominic Murphy, the Met's head of counter-terrorism, has been clear that we are seeing younger people drawn into conducting this activity on behalf of foreign states and has urged parents to pay attention to what their children are doing online. The successful prosecution in March 2024 under the National Security Act of two individuals responsible for an East London Arson incident on a London warehouse, storing supplies and technology destined for Ukraine, stands as stark warning to the consequences of this activity. The Government continues to support our world class law enforcement agencies in disrupting state threats including through the Department for Science, Innovation and Technology (DSIT) who have constructive relationships with the major social media platforms which have significant reach in the UK. DSIT engages with them on issues, emerging online narratives, or events that may pose a risk to UK public safety or national security.

The Royal Navy will enhance warfighting readiness over the next four years through the innovative transformation programmes of Atlantic Bastion, Atlantic Shield, and Atlantic Strike. The Atlantic Bastion capability options submitted for consideration in the DIP include a blend of uncrewed systems, underwater payloads, options to increase lethality, and improvements to crewed platforms. These are consistent with the pivot to a Hybrid Navy and reflect industry maturity to deliver.

Arctic Sentry remains a concept, rather than an agreed activity. Discussions are ongoing between Allies on how NATO can continue to bolster security in the High North to address the increasing threat from Russia.

The Defence Industrial Strategy (DIS) sets out steps to develop a more resilient UK industrial base and policies capable of adapting and surging to address emerging priorities and demands. It details steps to enhance the resilience of the industrial base and improve the readiness of supply chains. This includes regularly assessing the scalability and resilience of production for all major procurements and strengthening supply chain data and enhancing resilience of critical and cross-cutting supply chains (page 76, policies 6.2.2.3 and 6.2.3.1). Central to this is the Defence Supply Chain Capability Programme (DSCCP) which is pivotal to ensuring operational readiness and resilience across Defence and has scoped the work required to address critical minerals and component supply within Defence.

The autonomous systems are identified as a priority sub-sector in the DIS which include combat air, complex weapons, directed energy weapons and next-generation land and maritime capabilities.
