Britain announced a major restructuring of its armed forces, the Defence Investment Plan, inspired by lessons from the war in Ukraine. The plan prioritizes cheap drones, autonomous systems, and rapid innovation over expensive traditional platforms like destroyers and frigates. It includes investment in Common Combat Vessels as control ships for unmanned systems, a national Collaborative Combat Air program for autonomous jets, and Europe's largest drone testing center, with an additional £15 billion over the defense budget. This marks a fundamental shift in UK military strategy, reflecting the impact of drone warfare on modern conflict.

The UK Maritime Trade Operations (UKMTO) raised the threat level in the Strait of Hormuz to 'substantial' after a tanker reported being struck by an unidentified projectile. This follows US airstrikes on Iranian targets in response to Iranian drone attacks on shipping, and Iran has accused Washington of violating a ceasefire agreement. Iranian forces reportedly struck US positions in the region, and Bahrain was targeted by Iranian drones. The incident underscores escalating tensions between the US and Iran over control of the strategic waterway, threatening global energy transit.

UK Prime Minister Sir Keir Starmer launched the Defence Investment Plan (DIP) with over £5 billion over four years for drones and autonomous systems across the Royal Navy, Army, and RAF. The investment, described as the largest in UK history for such systems, implements the Strategic Defence Review and funds the Uncrewed Systems Centre in Swindon and a new Uncrewed Systems Taskforce. Specific programmes include the Royal Navy's Common Combat Vessels and uncrewed platforms, the Army's Project NYX and Project Corvus, and the RAF's Collaborative Combat Air programme. The plan is framed around lessons from conflicts in Ukraine and the Middle East.

The UK Ministry of Defence announced plans to build at least six Common Combat Vessels (CCVs), hybrid warships designed to command drones across air, surface, and subsurface domains, replacing the Type 45 destroyers and the cancelled Type 83 program. Defence Secretary Dan Jarvis stated the vessels will be British-built, supporting jobs, and will operate alongside Type 26 and Type 31 frigates and new uncrewed platforms (Types 91-94). The programme supports the Hybrid Navy strategy and is part of the Defence Investment Plan, anchoring three new Atlantic initiatives (Atlantic Bastion, Atlantic Shield, and Atlantic Strike) to counter Russian activity in the North Atlantic and High North, protect critical underwater infrastructure, and enhance NATO deterrence. Industry concepts from BAE Systems and Babcock are under consideration, with BAE proposing a system-of-systems approach and Babcock pitching its ARMOR Force concept using Type 31 frigates as command nodes for autonomous vessels. Delivery is expected from the early 2030s.

The Royal Navy's Astute-class attack submarine fleet has historically struggled with availability due to maintenance bottlenecks, dry-dock shortages, and specialist engineer scarcity. As of now, open-source tracking confirms that no attack submarines are at sea, a recurring problem. Two boats are inactive at Faslane after prolonged out-of-water periods, two are undergoing extended deep maintenance at Devonport, and only one recently returned from deployment but is not ready. A further boat is in trials, and the last is under construction. The maintenance bottleneck persists due to single-location deep maintenance capacity, dry-dock shortages, spare parts scarcity, and a lack of specialist engineers. This leaves Britain without its most potent conventional naval capability at a time of heightened Russian submarine activity in the North Atlantic, and also affects protection of nuclear deterrent submarines and carrier strike groups. The Navy has a recovery plan with modest early measures, but major infrastructure improvements at Devonport and on the Clyde will take years.

Background: UK Armed Forces Minister Al Carns previously warned that NATO must restructure for drone warfare, citing Russia's massive drone arsenal and UK investments. Today, the British Army announced it has fielded 10,000 small drones and thousands of autonomous systems within six months under Project AKSA, backed by £300 million in investment. General Sir Roly Walker, speaking at the RUSI Land Warfare Conference 2026, described the programme as a bottom-up revolution that pairs brigades with multiple industry partners and pushes development down to individual formations, moving the Army from episodic experimentation to continuous adaptation. The programme also delivered 50 operational-level electronic warfare systems and a brigade's worth of counter-UAS equipment, drawing lessons from the war in Ukraine. Walker set out an aim for half of the Army's annual capital expenditure to go on the most survivable 20% of its systems by 2030, and estimated the total addressable market for remote and autonomous systems at over £100 billion over ten years.

UK Prime Minister Keir Starmer resigned on June 22, 2026, after less than two years in office, leaving his promised 'reset' of UK-Africa relations largely unfulfilled. Despite initial high-level engagement and deals with Nigeria and South Africa, delivery lagged due to internal reshuffles, fiscal constraints (aid dropping to 0.3% of GNI by 2027), and shifting strategic priorities toward the EU and Gulf states. The UK's influence in Africa is fading compared to China, though the upcoming G20 presidency offers a potential opportunity for renewed engagement.

The UK Ministry of Defence announced a £500 million investment in a new class of larger amphibious transport ships to support the Future Commando Force, with the aim of integrating them with the Netherlands into a combined fleet. This follows the retirement of HMS Albion and HMS Bulwark in 2025 and builds on previous UK-NL cooperation under Project CATHERINA. The new vessels are part of a broader effort to modernise the UK Commando Force for operations in the High North and NATO's northern approaches.
