The fundamental argument of this briefing is that five apparently separate policy problems are actually one problem, and the UK is uniquely positioned to address them together:
The key insight: all five of these share the same underlying industrial base.
The UK has existing partial capability in each of these areas, concentrated in:
The strategic proposition: unify these into a coherent national industrial-security capability.
Global semiconductor manufacturing is catastrophically concentrated:
A Chinese blockade or invasion of Taiwan, assessed as plausible within the decade, would devastate the global semiconductor supply chain. Every advanced economy would face chip shortages so severe that normal economic activity would be impossible. Defence, telecommunications, automotive, consumer electronics all simultaneously disrupted.
Current US response (CHIPS Act, $52bn programme) is accelerating domestic US capacity but will not be sufficient. Current EU response (European Chips Act, €43bn) is too small and too fragmented to produce cutting-edge capacity.
The UK has no credible response currently. This is a strategic vulnerability that requires addressing.
EUV lithography machines, which print the smallest features on advanced chips, are produced by exactly one company: ASML in the Netherlands. Each machine costs ~$200m, weighs 180 tonnes, and takes months to install and calibrate. Without these machines, advanced semiconductor production is impossible.
A single accident, strategic decision, or geopolitical event affecting ASML could halt global advanced chip production. The concentration is a systemic risk that should not exist. No other country currently has credible path to alternative EUV capability.
The UK has the underlying capability to develop alternative lithography technology, if it chooses to invest. The precision optics, ultra-high vacuum, plasma physics, and control systems expertise exists in British industry and academia. What is missing is focused investment, integration, and strategic direction.
The Ukraine war has demonstrated that modern warfare consumes advanced electronics at scale. Every drone, missile, radar, communications system, and guided munition requires semiconductors. The UK's defence capability is downstream of its semiconductor access.
Moreover, defence R&D and semiconductor capability are interchangeable at the foundational technology level:
This means defence R&D investment builds transferable capability. Unlike previous eras where "defence technology" was narrowly specialised, the current generation of defence technology is built on the same industrial foundation as commercial advanced manufacturing.
The strategy operates on a deliberate ladder from existing capability toward sovereign cutting-edge. Each rung is independently valuable, and achieving higher rungs does not require abandoning lower ones.
Objective: Build out UK capability in laser systems, precision optics, autonomous systems, advanced materials, explicitly as defence capability with transferable industrial skills.
Objective: UK sovereign capability in mature node semiconductors (28nm and larger), covering most defence, automotive, industrial, and IoT applications.
Cost: £1.5bn/year capital for 5 years (£7.5bn total). Revenue £300m/year for ongoing support. Partial offset by returns on equity investment in successful ventures.
Objective: Build capability to produce 7-14nm chips, covering most high-performance industrial, automotive, and defence applications.
Cost: £6bn capital over 4 years, UK share. Revenue commitments as foundry operates commercially. This is at the upper end of what the fiscal framework can accommodate even with growing Y10 surplus.
Objective: Develop UK sovereign capability in advanced lithography, reducing global dependence on ASML and providing alternative path for advanced semiconductor manufacturing.
This is the most ambitious and most valuable rung. It is also the most uncertain and requires longest timelines.
Cost: £1bn/year sustained R&D investment for 10+ years. Delivery uncertain. Strategic upside enormous.
Objective: UK capability or guaranteed access to critical materials required for the entire stack.
Cost: £500m/year revenue plus capital as needed for specific mining and processing projects.
This requires a new institution. The strategy cannot be delivered via existing departmental structures because it crosses MOD, DSIT, DBT, Treasury, and intelligence community boundaries.
Proposed: National Sovereign Capability Office (NSCO)
Model: ARPA-E (US), BARDA (US), BPI-France structures as reference points. Not a regulator; a capability-building agency.

Capital financed via dedicated Sovereign Capability Infrastructure gilts, specifically positioned as strategic national assets. This framing is important for fiscal rules: these are not conventional public capital projects but national-security-essential industrial investments. Comparable to Second World War industrial mobilisation, though at peacetime scale.
Revenue addition: £3.4bn Y5, £4.6bn Y10, absorbed through:
Capital addition: Substantial but financed separately through infrastructure gilts. Does not affect current-budget balance.
This is the critical strategic framing. The Sovereign Capability programme connects to the Productive Britain reindustrialisation thesis in a specific and powerful way:
Step 1: Defence and national security create guaranteed state demand for advanced manufacturing capability. This is politically defensible ("national security essential") regardless of short-term commercial case.
Step 2: That guaranteed demand derisks private investment in the associated industrial base. Firms can invest in precision optics, UHV equipment, advanced materials knowing there is a state customer even if civil demand is volatile.
Step 3: Skills, supply chain, and technological capability developed for defence applications become transferable to civil applications. Engineers trained on DragonFire move to commercial laser applications; UHV expertise built for defence moves to semiconductor fabrication; materials science developed for defence moves to battery technology, photonics, pharmaceuticals.
Step 4: As civil applications grow, they begin to fund their own research and investment, reducing dependence on state funding and building genuine sovereign industrial capability.
Step 5: State can then mandate sovereign supply chains for national security critical applications (chip production mandate for NHS, defence, government systems) without anti-competitive concerns, because sovereign capability now genuinely exists.
Step 6: Local economies benefit through employment, skill development, and industrial activity in regions outside London/SE where these facilities concentrate (Midlands, North West, Scotland, Wales, South West).
This is how industrial policy compounds. Every other recent attempt at UK industrial policy has tried to build civil competitiveness directly, and failed because private investment cannot justify the capital commitment against uncertain demand. The Sovereign Capability approach uses defence as the demand anchor, derisks private investment off that anchor, and then lets the resulting capability expand into civil markets.
This is also precisely how the US built its own advanced technology industries (defence → civil for semiconductors, computing, internet, GPS, aerospace), how South Korea built its chaebol, and how France built its aerospace capability. The UK had something like this in the 1950s-70s and lost it; this is the route to recovery.
To defence constituency: "We will ensure British forces never again face the semiconductor constraints that have hampered every modern Western military. We will build sovereign capability in the technologies that defence depends on — lasers, precision optics, advanced chips, critical materials. We will do this because national security requires it."
To industry constituency: "The state will anchor demand for advanced industrial capability, derisking your private investment. Defence creates the demand floor; civilian applications create the growth trajectory. We are giving British industry a stable foundation from which to build the capabilities the country needs."
To regional constituencies: "Midlands, North West, Scotland, Wales — these are where the new industrial capability will be built. Not London. Not the South East. The regions that built Britain's industry will build its sovereign technology capability."
To young people and skills constituency: "Careers in cutting-edge manufacturing, precision engineering, advanced materials, semiconductor fabrication, optics. Real work, high wages, skill development, pride in building things Britain needs. This is the industrial future we are giving you."
To fiscal constituency: "The capital investment is substantial. But it is investment, not consumption. The strategic value — to national security, to industrial revival, to regional economies, to technological sovereignty — far exceeds the fiscal cost. This is how serious countries build capability."
This briefing, together with the Franco-British Nuclear Umbrella briefing, provides the international and strategic dimensions of the platform. Together they form the strategic foundation on which Productive Britain (flagship) will be built.
