Today the Government published its landmark Defence Investment Plan (DIP), backed by £298 billion of investment over the next four years. It is one of the most significant statements of intent for UK defence in a generation – and for the thousands of businesses that make up the defence supply chain, it provides the clarity they have been waiting for.

Announced by the Prime Minister, the plan adds £15 billion on top of last year’s Spending Review and lifts defence funding from £54 billion a year to almost £80 billion a year by 2029. That takes UK defence spending to 2.7% of GDP – the highest proportion in three decades — and puts the country on track to meet NATO’s targets by 2035.

What the plan delivers

The DIP turns the vision of the Strategic Defence Review into funded commitments. The headline announcements include more than £8 billion for the Global Combat Air Programme (GCAP), the next-generation stealth fighter being built with Japan and Italy; over £63 billion to strengthen the nuclear deterrent, funding Dreadnought and SSN-AUKUS submarines and a new warhead; and £26 billion for Project Royal Oak, the biggest naval base upgrade in over 45 years across Faslane, Portsmouth and Devonport.

Crucially for industry, the plan leans hard into new technology: over £5 billion for a drone transformation (including £650 million for inexpensive, expendable autonomous systems), nearly £2 billion for a Digital Targeting Web underpinned by AI, £11 billion for munitions and at least six new energetics factories, and £900 million to reform procurement — including a £500 million Transformation Fund. A new £50 billion UK Export Finance facility will help British defence firms of all sizes win contracts abroad.

Why the Plan matters

For the supply chain, the single most valuable thing the DIP provides is clarity. A four-year, costed pipeline allows companies to invest in capacity, recruit and train people, and build the partnerships needed to deliver — confident that the demand is real, durable and funded. The plan is forecast to create nearly 60,000 extra direct and indirect industry jobs by the end of the decade, taking the total number of UK jobs supported by defence spending to more than half a million.

Just as important, the Government has signalled that how it spends will change. The emphasis on procurement reform, on giving credit to British-based companies with a genuine presence in UK communities, and on faster routes to market opens real opportunity for SMEs, mid-tier firms and regional clusters that have too often found the barriers to entry high. The plan will only succeed if that money reaches the innovators who can turn it into capability at pace.

The DIP also recognises the value of exporting opportunities, with a £50bn defence export fund announced to further boost the success of UK organisations abroad.

From investment to contract:  how the DPRTE UK Defence Summit supports the DIP

Funding announced is not the same as capability delivered. The drones, AI, cyber, advanced manufacturing and energetics commitments in the DIP all depend on a broad, agile and resilient supplier base – exactly the kinds of organisation that will gather at the DPRTE UK Defence Procurement & Supply Chain Summit in Manchester on 22 October 2026.

Centred around the core message: “From Defence Investment to Contract: Where Your Organisation Wins Work,” the Summit connects government, prime contractors and suppliers to translate policy and procurement reform into real, contracted opportunity. It is built precisely for the non-traditional entrants, SMEs and mid-tier organisations the DIP needs: helping them understand where the growth is, how reform is reducing barriers, and how to access the pipeline. The DIP sets the destination; events like the Summit (and next year’s DPRTE Expo) are where the supply chain finds its route to delivering it.

Industry reaction

“The release of the Defence Investment Plan marks a decisive step forward in securing our nation’s strategic future and provides the long-term certainty that our defence industrial base has been calling for. 

By backing British innovation, investing in next-generation capabilities and opening up opportunities for small and medium enterprises, this plan secures the future of our sovereign capabilities.”

Professor Andrew Schofield, Chair of the North West Regional Defence & Security Cluster

A defining moment – if we deliver it together

The Defence Investment Plan is a clear, well-funded signal to allies, adversaries and industry alike that Britain is stepping up. The opportunity now is to make sure that investment flows through the whole supply chain — from the primes to the smallest specialist SME — so that every pound, as the Prime Minister put it, “works twice” for national security and economic growth. Getting the right organisations in the room, ready to act, is how that happens.
