UK Defence Journal Weekly Brief

Welcome to the UK Defence Journal Weekly Brief, our snapshot of the key developments shaping UK defence policy, procurement and industry, and what to watch in the week ahead.

Week in Context

Prime Minister Keir Starmer spoke on the need to “go faster” on defence spending amid reports of plans to accelerate towards 3% of GDP.

Meanwhile, the UK’s Chief of Defence Staff and Germany’s Chief of Defence jointly called for large-scale rearmament as a “moral obligation” to counter Russia’s military buildup, highlighting the risks posed by Moscow’s actions in Ukraine and the need for a stronger European defence posture.

Industry developments were more upbeat. The UK joined France, Germany, Italy, and Poland in launching an initiative to develop new low-cost air defence weapons and autonomous systems, aimed at protecting against aerial threats and drawing on lessons from ongoing conflicts to enhance NATO’s collective security.

Policy and Parliament

This week focused heavily on delivery timelines, affordability and the practical consequences of recent strategic decisions. Ministers confirmed that Full Operating Capability for Ajax remains expected by the end of 2029, with safety investigations and a Ministerial Review of the Armoured Cavalry Programme ongoing. The response indicates that, despite earlier turbulence, the programme timetable has not formally shifted.

The government also published an annual breakdown of its planned £270 billion defence spend this Parliament, setting out MOD settlements rising from £62.2 billion in 2025–26 to £73.5 billion in 2028–29. The figures equate to between 2.01 and 2.13 per cent of GDP across those years, alongside the assertion that overall NATO-qualifying defence spending will reach 2.6 per cent of GDP in 2027. Ministers further confirmed that certain financial transactions are included within NATO spending calculations, describing them as integral to sustaining sovereign manufacturing capability.

On the Strategic Defence Review, repeated questions sought clarity on whether its recommendations were fully costed before publication. Ministers stated that the external reviewers worked to terms of reference requiring proposals to be deliverable and affordable within the fiscal envelope available, with the forthcoming Defence Investment Plan expected to translate those recommendations into an executable programme. The answers reinforce that the DIP remains the mechanism through which strategic ambition will be reconciled with budget reality.

Industrial resilience and skills also featured. The Ministry of Defence reiterated its commitment to combat air manufacturing in the UK, highlighting ongoing engagement with trade unions and support through the Combat Air Strategy and the Global Combat Air Programme. At Porton Down, ministers confirmed that Dstl will remain at its core site for the long term, with continued infrastructure investment including a new chemical weapons defence facility.

Elsewhere, responses touched on housing reform under the Defence Housing Strategy, progress on integrating digital targeting initiatives within the Royal Navy, investment in drone deliveries to Ukraine, and the handling of sensitive operational details such as aircraft deployments and vessel out-of-service dates.

Procurement and Industry

Defence industrial developments last week combined targeted contract awards with continued uncertainty around several larger programmes.

A notable procurement announcement saw the Ministry of Defence award a £12 million contract to Warrington-based Amentum UK to support development of a sovereign hypersonic missile capability. The work is intended to accelerate progress towards a long-range hypersonic strike demonstrator before the end of the decade. The award was placed within just over a month of the invitation to tender, highlighting efforts to shorten acquisition timelines in areas judged critical to future deterrence.

In the autonomy domain, Applied Intuition UK secured a Defence Science and Technology Laboratory contract to lead a consortium delivering an autonomy test bed for ground-launched, near-surface drone swarms under the Software Defined Swarms programme. The project will combine simulation and live trials to develop and test swarming behaviours, contributing to the UK’s growing investment in uncrewed and collaborative systems.

The Ministry of Defence also placed a contract worth around £5 million for the OWE Launcher with Threod Systems AS under a direct award procedure, supporting deep fires capability for forces deployed on Operation Cabrit.

Despite these focused investments in hypersonics, autonomy and long-range fires, longer-term decisions remain outstanding. The New Medium Helicopter competition is still unresolved, with ministers stating that a decision will be taken as part of the forthcoming Defence Investment Plan but offering no fixed timetable. With Leonardo’s best and final offer for the AW149 having expired in March, the future of sovereign helicopter assembly and associated jobs remains uncertain.

Operations and Activity

In the air, the Royal Air Force concluded two weeks of intense flying on Exercise Red Flag at Nellis AFB, Nevada. It deployed 14 aircraft, including 12 Typhoons, a Rivet Joint from 51 Squadron, and a Voyager tanker, working alongside US and Australian partners. The exercise included close collaboration between RAF and USAF Rivet Joints for the first time. RAF forces then moved straight into Exercise Bamboo Eagle, shifting to a defensive role to sharpen integrated tactics.

At sea, the Royal Navy achieved a key AUKUS milestone when Astute-class submarine HMS Anson arrived at HMAS Stirling, Western Australia, for its first maintenance period in the country. UK, Australian and US personnel worked together on routine sustainment to build skills for nuclear-powered submarine operations in the Indo-Pacific.

On the ground, British Army units continued to apply lessons from Ukraine. The 1st Battalion Irish Guards set up mobile 3D-printing at their new drone warfare training facility in Aldershot to produce drone parts and training equipment on site. Army personnel also joined the multinational Defence Cyber Marvel 2026 exercise in Singapore with allies, including the Japanese Ground Self-Defense Force, to practise countering cyber threats.

What We’re Watching

In the week ahead, attention will remain on how the forthcoming Defence Investment Plan is turned into clear funding and delivery commitments. Recent parliamentary answers have reaffirmed spending totals and long-term ambition, but industry will be looking for practical detail on timelines, sequencing and which programmes move first.

Recent contracts in areas such as hypersonics and autonomy suggest movement in priority fields, yet larger decisions, including helicopter procurement and other major platforms, remain unresolved.
