The long-anticipated outcome of the Strategic Defence Review (SDR) has finally landed[1] — and it’s a bold declaration: 62 transformative reforms spanning AI, submarines, munitions factories and digital warfare — all driven by a vision of a tech-empowerment.
The SDR report marks an unprecedented, transformational moment in UK defence, but what might it mean for businesses and can it realistically deliver on its ambitious goals?
This briefing is a high-level, early assessment, designed to outline the key shifts in strategy, procurement, industrial policy, and innovation rather than to provide definitive answers. Only time, and detailed implementation, will tell.
Over the coming months, we’ll be releasing a series of follow-up articles and events diving deeper into specific themes, from procurement transitions to tech investment and SME access, to help businesses navigate evolving opportunities under the SDR.
In July 2024, the Labour government launched the SDR, led by Lord Robertson (former Defence Secretary and NATO Secretary General) with support from Dr Fiona Hill and General Sir Richard Barrons. The SDR was commissioned in response to the UK and its allies confronting the most serious security threats since the Cold War. This includes conflicts in Europe, rising nuclear tensions and adversary alliances, and increasingly sophisticated cyber campaigns and hybrid warfare strategies.
The SDR report provides a comprehensive ‘root and branch’ review of the UK defence landscape, drawing on extensive evidence gathering from over 8,000 contributions from a broad variety of stakeholders and integrating lessons learned from the war in Ukraine to inform the wide-ranging recommendations.
The SDR report sets a clear and bold vision for the UK by 2035: to become: “A leading tech-enabled defence power, with an Integrated Force that deters, fights, and wins through constant innovation at wartime pace.”
This encapsulates the goal to make the UK safer, secure at home and strong abroad.
The SDR sets out five ‘ambitions’ and an impressive 62 recommendations across those ambitions to support this vision. The UK Government has accepted all recommendations for implementation. We have set out below the five ambitions and some of the key recommendations under them:
To support the successful implementation of the recommendations, the SDR report states that the whole of the UK Defence should be driven by the logic of the ‘innovation cycle’: (i) Find it: Defence must be able to seed early-stage research, using its purchasing power to shape the commercial market;(ii) Buy it: Defence must be able to get innovation and new capabilities to the front line at speed, creating the conditions for the market to invest, experiment, and scale; and (iii) Use it: Defence must continually develop its people’s skill set, adapt its organisation, and exploit a common digital foundation to which all software-enabled assets connect.
The SDR marks a shift from conventional capabilities toward warfighting readiness and high-technology weaponry. By emphasising digital innovation, drone technology, and industrial production, the government is creating opportunities for suppliers who can deliver on UK defence requirements at pace. Suppliers should note the emphasis on local production, an “engine for growth,” and the promise of a more agile procurement process to expedite vital assets to the front line. Internationally, the reaffirmed NATO-first commitment reinforces Britain’s role in Euro-Atlantic defence at a time of rising geopolitical instability. The potential for economic stimulus is significant as, by prioritising UK-based production, from munitions to submarine construction, the government aims to revitalise domestic industry, create sustainable jobs, and secure supply chains.
Yet, realising these SDR ambitions will need to be translated into specific investment decisions (which we understand will be taken later this year (Autumn) as part of the development of a Defence Investment Plan) and will require radical reforms to the defence procurement system (which the Public Accounts Committee and Defence Select Committee have both called ‘broken’).
Those involved or looking to enter the defence sector should closely monitor the policy direction and implementation of the SDR’s recommendations, as they will shape not only the future of UK defence policy, but also the landscape of the international defence market in which the UK is a key player. Stakeholders should consider how they may seek to align with the SDR’s ambitions and vision and keep a close eye on the development of the Defence Investment Plan.
Please keep an eye out for our upcoming events, insights and deep dives into the SDR and the implementation of its recommendations.
