Since the Defence Investment Plan landed at the end of June 2026, the conversation among suppliers has understandably focused on one question: where's the money going?
The scale is significant. The plan covers almost £298 billion of defence spending over four years and includes major commitments across autonomy, digital systems, cyber, space, munitions, infrastructure and the wider UK defence industrial base. But a funding announcement is not the same thing as a procurement opportunity. Different programmes will reach suppliers through very different commercial routes.
We covered the headline picture in our earlier look at what the Defence Investment Plan means for UK suppliers. This time, we're going sector by sector, looking at where some of the biggest funding commitments sit and, just as importantly, how suppliers in each area are likely to encounter opportunities.
A quick recap
The Defence Investment Plan provides for approximately £298 billion of Ministry of Defence spending between 2026/27 and 2029/30, supported by an additional £15 billion in spending power compared with the position agreed at the previous Spending Review. It implements many of the priorities set out in the 2025 Strategic Defence Review, including:
- Greater use of AI and autonomous systems
- A more integrated digital force
- Increased cyber and electromagnetic capability
- Investment in space
- Rebuilding munitions capacity
- Modernising military infrastructure
- Strengthening the UK defence industrial base
The full Defence Investment Plan document sets out how that money is distributed across programmes, capabilities and the wider defence estate, and it's worth reading if you want the complete picture.
Autonomy and drones: £5 billion
Autonomous systems sit right at the centre of the DIP's thinking, with £5 billion committed to drones and autonomous systems. That funding covers areas including strike and surveillance drones, the Royal Navy's move towards a hybrid fleet and uncrewed land vehicles.
Programmes such as the Army's Project NYX and CORVUS give a sense of what this can mean in practice, alongside continued investment in uncrewed systems and rapid experimentation.
This is also one of the more accessible entry points into defence for smaller and newer technology suppliers. UK Defence Innovation committed more than £140 million to drone and counter-drone technologies in its first year, with funding going to British SMEs, micro-SMEs and academic institutions as well as larger suppliers.
UKDI has since identified Autonomy as one of its five core innovation themes, alongside Decision Advantage, Logistics and Support, Effects and Protection.
If you're new to defence and building capability in autonomy, uncrewed systems or related technologies, innovation competitions and early market engagement can therefore be a more realistic first step than trying to enter a Tier 1 prime's established supply chain from a standing start.
Cyber and the digital backbone: £2.5 billion, plus £7.3 billion
The DIP includes £2.5 billion for sustaining and growing the Defence Cyber and Electromagnetic Force, while nearly £7.3 billion is identified for the digital targeting web and the digital infrastructure that supports it.
Together, these represent one of the largest areas of technology investment in the plan. The intention is to connect sensors, decision-makers and systems across defence more effectively, while increasing the use of AI and modern digital capability.
Routes to market here can include DE&S digital and technology competitions, innovation programmes and dynamic purchasing systems.
Programme FRONTIER is one example of the direction this work is taking. Led through the Defence AI Centre, it is intended to turn advanced AI into practical defence capability, initially focusing on areas including cyber security, homeland defence and warfighting readiness.
For suppliers wanting to win contracts in the UK defence sector through digital and cyber routes, registering on relevant procurement systems and monitoring early market engagement is worth doing before a full competition goes live.
Space: £3.2 billion
Space capability receives £3.2 billion, covering areas including space-based intelligence, surveillance and reconnaissance and the protection of UK assets in orbit. The DIP also points towards a greater role for commercial solutions and service-based models alongside more traditional procurement.
Space contracts can involve long procurement cycles, specialist assurance requirements and established supplier relationships, so this is not necessarily the simplest entry point for a business completely new to defence. But the funding commitment and growing interest in commercial capability mean it's a market worth watching closely if your technology genuinely fits.
For suppliers already operating in satellite services, communications, data, cyber or related technologies, early engagement may matter just as much as reacting to a contract notice once it's published.
Munitions and advanced manufacturing: £11 billion
Munitions and weapons receive £11 billion, supporting increased UK stockpiles, long-range capabilities and at least six new energetics and munitions factories by 2030. This sits alongside a much broader emphasis on rebuilding sovereign manufacturing capacity and strengthening the resilience of the UK defence industrial base. It's also an area where suppliers are more likely to encounter national security considerations in procurement.
Where a contracting authority genuinely believes a procurement is indispensable to national security, the national security exemption under Schedule 2 to the Procurement Act 2023 may apply. The important point for suppliers is not to assume every defence opportunity will appear as a conventional open, advertised tender.
For businesses in advanced manufacturing, components, engineering, materials and associated services, building relationships with relevant primes and understanding their supply chains may therefore matter just as much as watching published opportunities.
Routes to market
It's worth being clear about something that catches a lot of suppliers out: "defence procurement" isn't one single system. Some defence-related spending is procured under the Procurement Act 2023. Other activity sits under the separate defence and security regime that predates it. And where the national security exemption is legitimately applied, the usual procurement requirements may not apply in the same way.
This matters particularly for spending that sits outside headline equipment programmes, such as the estates and infrastructure work that supports them.
The DIP includes £26 billion over the next decade for upgrades at HMNB Devonport, Portsmouth and Clyde, alongside £9 billion of investment in defence housing.
Work of that kind can reach the market through a mixture of direct procurement, major infrastructure programmes, framework arrangements and the supply chains of principal contractors. For suppliers, that means understanding which programmes are moving towards delivery and who is already involved can be as important as simply searching for standalone notices.
The House of Commons Library's summary of the DIP's key decisions is a useful independent resource for understanding which programmes are furthest along and therefore potentially closest to generating real supply-chain activity.
The "backing British" thread
Running through all of this is a clear emphasis on UK-based businesses, skills and industrial capability.
The Defence Industrial Strategy originally proposed a new offsets regime to capture wider UK economic benefits where defence equipment is bought from overseas suppliers. The consultation on that proposal closed in December 2025, and ministers have since said that the government is introducing an offsets regime, although detailed implementation continues to develop.
We covered the wider version of this shift, which extends well beyond defence, in our earlier piece on the government's Buying British Pledge.
For UK-based suppliers and subcontractors, the practical lesson is to be specific about your economic contribution. Where it is relevant to the procurement, evidence around UK jobs, skills, manufacturing capability, supply-chain resilience and investment is likely to be much stronger than a generic claim that you're a "British business".
What this means for positioning now
None of the sectors above are static. New competitions, contract awards and funding announcements are appearing regularly, and it's worth checking the government's defence investment and procurement channels if you're tracking a particular sector closely.
There are also already examples of new activity coming out of UKDI. On 2 September, for instance, UK Defence Innovation launched Project PANOPTES, a counter-uncrewed aerial system competition with £5 million immediately available to UK-based innovators. That gives a useful indication of how some of the broader autonomy and protection priorities in the DIP can turn into specific competitions.
At Thornton & Lowe, we help defence and technology suppliers translate plans like this into a realistic bid strategy, from working out which route to market actually fits your business to building the evidence a buyer or prime will want to see.
If you're trying to work out where the Defence Investment Plan creates a genuine opportunity for your organisation, we're happy to talk it through. Our Tender Pipeline tool is also worth using to keep an eye on live and upcoming defence opportunities as they come to market.
