Lifecycle: Implementation Defence Committee · HM Treasury · Ministry of Defence · Public Accounts Committee Last regenerated 25 minutes ago

Summary

What this is

A multi-instrument defence investment regime in which the Strategic Defence Review 2025 sets capability priorities, the Defence Industrial Strategy 2025 sets industrial and skills policy, and a forthcoming Defence Investment Plan (DIP) will operationalise both into a 10-year capital and resource envelope — supported by Defence Growth Deals, UK Defence Innovation, and the National Armaments Director Group acquisition spine.

Why it matters

The regime is the largest sustained increase in UK defence spending since the Cold War — committing to 2.5% of GDP by 2027 and an ambition of 3% in the next Parliament — and reshapes industrial policy, procurement architecture and regional growth simultaneously. Delay to the DIP is creating live affordability, industry-investment and parliamentary-scrutiny risks.

Current status

SDR was published in June 2025 with 62 recommendations all accepted; the DIS launched 8 September 2025 with £250m for five Defence Growth Deals and a £182m Defence Industry Skills Package; four of five Growth Deals are launched; the DIP has slipped past its expected publication window with publication 'as soon as possible' and was still unpublished at the close of the events window.

What changed recently

  • 29 Apr 2026 — Three written questions on DIP progress, Northern Ireland industrial capacity and MOD financial cuts went unanswered before Prorogation, deferring substantive parliamentary scrutiny. →
  • 28 Apr 2026 — Commons debate on Defence Industrial Strategy with Chief Secretary to the Treasury responding — signalling Treasury co-ownership of industrial delivery. →
  • 22 Apr 2026 — Northern Ireland Defence Growth Deal (£50m) launched, completing the five-deal package announced in DIS. →
  • 22 Apr 2026 — Government confirmed the DIP is a 10-year plan and the first zero-based review of Defence budgets in 18 years. →
  • 24 Mar 2026 — Defence Committee held one-off oral evidence session on the impact of DIP delay on industry — escalation from PQ scrutiny to committee inquiry. →

Open questions & gaps

Known gaps in the evidence base and what's still pending.

Pending in the lifecycle

  • Publication date of the Defence Investment Plan — repeatedly described as 'as soon as possible' with no firm window.
  • Cost envelope of accepting all 62 SDR recommendations — answer points to the DIP as the cumulative cash figure.
  • Allocation of £182m Defence Industry Skills Package to nations and regions beyond the £50m Scotland deal already launched.
  • Whether named platforms (Royal Navy minesweepers, Proteus, New Medium Helicopter, RAF Wyton infrastructure, Strategic Reserve) are inside the DIP envelope.
  • Feasibility-study outcomes for new munitions factories (contracted spring 2026, conclude August 2026; investment decisions Q3 2026).

Beyond the corpus

  • MISSING Defence Finance and Economic Network paper — Implied by the DIS recommendations but not yet published per March 2026 PQs.
  • MISSING Annual SME Action Plan with direct spending target — MOD has committed to publish an annual SME Action Plan; current plans suggest the full plan with spending target is not imminent.
  • MISSING Government response to the Defence Committee's affordability inquiry — Inquiry is open; no published response yet.
  • MISSING NAO 'Affordability of the MoD's Investment Plan' report — Work in progress as of August 2025; publication will set the independent audit baseline.
  • MISSING Northern Ireland Defence Growth Deal documentation — Launched April 2026 but full deal paperwork and skills-package allocation not yet in the corpus.

Confidence gaps

  • Whether £400m ringfenced UKDI budget continues at that level beyond first-year drone/counter-drone spend.
  • Sequencing inside the DIP between munitions factories, nuclear capital, and Royal Navy/Royal Fleet Auxiliary recapitalisation.
  • Treatment of legacy projects (£1.5bn flagged in qualified MOD Accounts 2024-25) inside the zero-based review.
