The United Kingdom 🇬🇧 has announced a major shift in its defense and nuclear policy, aiming to strengthen its position within NATO and respond to growing security threats in Europe and beyond. On June 2, 2025, Prime Minister Keir Starmer introduced the Strategic Defence Review (SDR) in Glasgow, setting out a new direction for the country’s military and nuclear strategy. This move marks the most significant change in the United Kingdom’s defense approach since the Cold War, with wide-reaching effects for NATO, European security, and the country’s own defense industry.
What Is Changing in the UK’s Nuclear Strategy?
The 2025 Strategic Defence Review lays out a plan for the United Kingdom to take on a bigger role in NATO’s nuclear mission. For the first time, the UK is openly considering joining NATO’s tactical nuclear sharing arrangements. Until now, only the United States 🇺🇸 and some European host countries have taken part in this program, which involves sharing nuclear weapons and responsibilities among NATO members.
The United Kingdom’s new approach includes:
- Starting talks with the United States 🇺🇸 and NATO about how the UK can help more with NATO’s nuclear mission.
- Investing £15 billion (about $20.3 billion) to speed up its own nuclear warhead program, making sure the UK keeps an independent and credible nuclear deterrent.
- Looking at buying F-35A fighter jets, which can carry US B61 nuclear bombs, unlike the UK’s current F-35B jets.
- Improving training and exercises to prepare for situations where nuclear weapons might be used.
This shift is meant to make the United Kingdom a stronger and more reliable partner in NATO, especially at a time when security threats are becoming more serious and less predictable.
Why Is the UK Making These Changes?
Several factors have pushed the United Kingdom to rethink its nuclear and defense strategy:
1. Russian Aggression: The ongoing war in Ukraine and threats from Russia have made European countries more worried about their safety. Russia’s nuclear threats have added to these concerns.
2. Uncertainty About US Commitments: President Trump’s statements about possibly pulling US troops out of Europe have made some NATO members question how much they can rely on the United States 🇺🇸 for protection.
3. New Technology in Warfare: The SDR points out that technology is changing how wars are fought. For example, drones are now causing more deaths in Ukraine than traditional artillery.
4. Collapse of Nuclear Arms Control: Agreements that used to limit nuclear weapons are breaking down, and Russia is modernizing its nuclear forces.
5. China’s Growing Nuclear Power: China is building up its nuclear arsenal and may work more closely with Russia, which could put extra pressure on US nuclear forces and make a stronger UK role in NATO even more important.
Prime Minister Starmer has said that these changes are about making the United Kingdom a “battle-ready, armor-clad nation” with the strongest alliances and the most advanced capabilities. The government wants security and defense to be at the heart of everything it does.
Key Parts of the New Nuclear Strategy
The United Kingdom’s new nuclear strategy has several important parts:
Nuclear Deterrent Triple Lock
The government has promised to keep its “nuclear triple lock,” which means:
- Building four Dreadnought Class submarines at Barrow-in-Furness to carry nuclear missiles.
- Keeping Continuous At-Sea Deterrence (CASD), which means at least one UK submarine with nuclear weapons is always on patrol.
- Upgrading submarines so they can keep doing their job in the future.
Enhanced NATO Nuclear Integration
The SDR calls for the United Kingdom to work more closely with NATO on nuclear matters. This could include:
- Joining NATO’s tactical nuclear mission, which would mean the UK could help deliver US nuclear weapons if needed.
- Buying F-35A aircraft, which can carry US nuclear bombs, unlike the UK’s current F-35Bs.
- Improving training and exercises to get ready for situations where nuclear weapons might be used.
Nuclear Fuels Programme
In November 2024, the United Kingdom announced it would look at ways to restart its own nuclear fuel cycle for defense purposes. This means making the fuel needed for nuclear reactors that power submarines, while still following international rules like the Non-Proliferation Treaty (NPT).
Nuclear Regulatory Review
In February 2025, the government set up a special taskforce, led by John Fingleton CBE, to review how nuclear activities are regulated in the United Kingdom. This review covers laws, the role of regulators, resources, and how to encourage new ideas in the nuclear sector.
How Does This Affect NATO and European Security?
The United Kingdom’s new strategy is designed to make NATO stronger and more flexible in the face of new threats. By taking on a bigger role in NATO’s nuclear mission, the UK hopes to:
- Show its commitment to NATO, especially at a time when some members worry about the United States 🇺🇸 pulling back.
- Help deter Russia by making it clear that NATO has strong and reliable nuclear forces.
- Support European security by sharing the burden of nuclear defense more widely among NATO members.
However, there are also challenges. Some experts point out that even if the United Kingdom joins NATO’s nuclear sharing program, the nuclear weapons would still be under US control. This means it might not fully solve worries about the United States 🇺🇸 leaving Europe on its own.
What Are the Other Big Changes in UK Defense Policy?
The changes to the nuclear strategy are part of a much bigger transformation of the United Kingdom’s defense policy. The SDR also includes:
Building Up Conventional Forces
- Making 7,000 long-range and cruise missiles
- Building six new munitions factories
- Working with Germany to develop new long-range missiles
Investing in Space and Anti-Satellite Weapons
For the first time, the United Kingdom is planning to develop both space-based and ground-based weapons that can target satellites. This is a big change and shows how important space is becoming in modern warfare.
Increasing Defense Spending
The government has promised to raise defense spending to 2.5% of GDP by 2027 and to 3% in the next Parliament if the economy allows. This is a big increase and shows how seriously the United Kingdom is taking these new threats.
Modernizing the Army
The SDR aims to make the British Army “ten times more lethal by 2035” by using new technology like autonomous (self-driving) systems and digital targeting, learning from the war in Ukraine.
Whole-of-Society Approach
The review says that defense is not just about the military. It’s about making the whole country more resilient, including the economy, industry, and society.
What Do Experts Say?
Defense experts have highlighted several important points about the United Kingdom’s new nuclear and defense strategy:
- Managing Escalation: The focus on being able to respond to different levels of conflict, including limited nuclear use, shows that the UK is worried about Russia using nuclear weapons in a crisis.
- Limits of Nuclear Sharing: Some critics say that joining NATO’s nuclear sharing program may not fully solve the problem if the United States 🇺🇸 decides to leave Europe, since the weapons would still be under US control.
- Building Industrial Strength: The SDR stresses the need to rebuild the United Kingdom’s nuclear industry, which has weakened over time. A strong industrial base is needed to support a credible nuclear deterrent.
- Improving Regulation: The Office for Nuclear Regulation’s 2025-2026 Corporate Plan focuses on building capacity, improving funding, using digital tools, and working more with international partners to support the new nuclear mission.
What Happens Next?
The United Kingdom’s plan to take on a bigger nuclear role in NATO will require careful planning and cooperation with allies. Some of the next steps include:
- Talking with NATO and the United States 🇺🇸 to work out the details of the UK’s new role in the nuclear mission.
- Deciding whether to buy F-35A aircraft and training pilots to use them for nuclear missions.
- Carrying out the Nuclear Regulatory Review to make sure safety and security are balanced with the need to move quickly on new projects.
- Rebuilding industrial capacity to support the faster nuclear warhead program.
- Managing public opinion about the costs and risks of a bigger nuclear role.
What Does This Mean for Immigrants, Workers, and the Public?
The changes in the United Kingdom’s defense and nuclear policy will have effects beyond the military. Here’s what different groups might expect:
Immigrants and Skilled Workers
- More Jobs in Defense and Nuclear Industries: The push to build new submarines, missiles, and factories will likely create more jobs in engineering, manufacturing, and science. This could mean more opportunities for skilled immigrants, especially those with backgrounds in nuclear science, engineering, or defense technology.
- Security Clearances: Working in sensitive areas like nuclear defense may require security clearances, which can be harder for non-citizens to get. However, the need for skilled workers could lead to changes in how these clearances are handled or to special visa programs for key talent.
- Training and Education: The government may invest more in training programs to help both citizens and immigrants gain the skills needed for these new jobs.
Employers and Industry
- Increased Demand for Skilled Labor: Companies working in defense and nuclear sectors will need to hire more people with specialized skills. This could lead to partnerships with universities and training centers.
- Opportunities for Innovation: The focus on new technology, like autonomous systems and space weapons, could drive innovation and create new business opportunities.
The General Public
- Higher Defense Spending: The commitment to spend more on defense may mean less money for other areas, like health or education, unless the economy grows enough to cover the extra costs.
- Public Debate: There may be debates about the risks and benefits of a bigger nuclear role, especially given the high costs and the dangers of nuclear weapons.
