Yesterday’s Strategic Defence Review (SDR) had been a long time coming. Commissioned nearly a year ago as a “root and branch review” of the UK’s armed forces, the announcement underscores Keir Starmer’s ambition to overhaul the State’s delivery capacity. Emphasising that the review was intended to ensure the transition to “war-fighting readiness” in a time of global uncertainty, the Prime Minister has thrown his support behind large-scale reform and investment aimed at modernizing the UK’s military capabilities, while reinforcing our international commitments to NATO. While there is widespread support for the tone and aims of the announcement, it was not without its critics over a perceived absence of funding details and lack of clarity on some targets.
The review, presented by an independent panel including Lord Robertson, Dr Fiona Hill, and General Richard Barrons, contains 62 recommendations, all of which Starmer has accepted. These span a wide range of issues, from new munitions factories and submarines to cyber resilience and military housing. Taken together, they signal that, for the first time in at least twenty years, there is a new permissive environment for defence procurement in the UK.
The caveat, of course, is that while there were significant promises on funding and on shortening timelines, details on these were decidedly murky.
Many of the SDR’s announcements had been trailed for weeks, if not months; the Government revealed in February that spending in the sector would rise to 2.5% of GDP by April 2027. However, pressure still remains over the date at which the holy grail of 3% will be reached – something Defence Secretary John Healey MP has said will happen “no doubt” before 2034.
The Prime Minister and his team are well aware of the economic and electoral traps they will walk into if they promise to reach this figure at a specific date, but appearing to make unfunded promises is also a risk in itself. Seeming to ‘kick the can down the road’ on funding is at odds with the well-founded urgency which set the tone for the Prime Minister’s speech, while targets such as ‘up to 12’ new attack submarines could uncharitably be interpreted as being likely to end up at the lower end of that scale.
Speaking at BAE Systems’ shipyard in Govan, Glasgow, Starmer also championed the so called “defence dividend,” the economic boost expected from increased defence spending. Citing the 10,000 jobs six new munitions factories and a £15bn boost in the UK’s Sovereign Warhead Programme would create, Starmer clearly sees the sector as vital part of his mission towards growth and increased industrial capacity. Framing the spending boost as “military Keynesianism”, he’s also keen to ward off those to his left who have complained ahead of next week’s spending review that he and the Chancellor are not being bold enough on spending.
Starmer framed yesterday’s review as positioning the UK as the fastest military innovator in the world. Recognising that changing threats – particularly in cyber and from Russia – had warped traditional notions of national security he added that “the front line, if you like, is here”. To this end, he focused less on traditional ‘boots on the ground’ and instead promised the creation of a cyber command to lead offensive cyber operations as well as a re-established Home Guard to protect critical infrastructure. Alongside new money, the Prime Minister has endorsed the most radical shake-up of defence governance in a generation, abolishing the Levene reforms, cutting procurement timelines, and establishing a Military Strategic HQ with direct authority over service chiefs.
Internationally, the review marks a clear reaffirmation of the UK’s commitment to NATO and multilateral defence cooperation. In an era where scepticism toward international institutions is gaining traction, particularly on the political right, Starmer has doubled down on alliance-based security. His embrace of NATO, reinforced by recent moves toward deeper European defence integration, draws a sharp contrast with the isolationist rhetoric of figures like Nigel Farage. Yet this alignment comes with diplomatic nuance: while strengthening ties with European allies, the Prime Minister must also navigate the sensitivities of the transatlantic relationship, ensuring that Britain’s strategic pivot doesn’t unsettle Washington.
