The €1.85B UK Defence Investment Plan: What it Means for the Quantum Industry

1 July, 2026 2:00 pm

The UK Ministry of Defence has released its new Defence Investment Plan (DIP), establishing a clear shift in how the military intends to procure, scale, and deploy emerging technologies. For the quantum ecosystem, this document marks a critical transition: quantum is moving decisively out of experimental labs and directly into defence procurement pipelines.

The Strategic Framework

At the core of this strategy is a £1.6 billion commitment to UK Defence Innovation (UKDI) (approx. €1.85B) over the next four years. Crucially, this funding targets “dual-use” technologies. The UK Ministry of Defence (MOD) recognizes that building a resilient quantum supply chain requires deep integration with commercial industry, rather than relying on isolated defence-specific R&D.

For industry leaders, system integrators, and deep-tech startups, the plan highlights three primary areas where quantum capabilities are being fast-tracked into frontline deployment:

  1. Sovereign Navigation & Alternative PNT: Electronic warfare and satellite jamming have made GPS vulnerability a top operational risk. The DIP explicitly prioritizes quantum sensing and atomic clocks to enable precise, un-jammable navigation across contested environments—reducing reliance on space-based assets.
  2. Hardening the Digital Backbone: With the long-term cryptographic risks posed by quantum computing developments, the MOD is prioritizing the immediate integration of quantum-resistant cryptography into command-and-control networks to secure communications against future intercept-now, decrypt-later tactics.
  3. Multi-Domain Hardware Integration: Quantum systems are no longer treated as standalone projects. The investment plan mandates integrating these technologies into high-priority platforms, including the Navy, Combat Air and intelligence.

The Industrial Outlook

For the quantum industry, the message is clear: the defence sector is shifting its focus from basic scientific discovery to engineering, manufacturing, and high-TRL (Technology Readiness Level) deployment. To participate in these procurement pipelines, companies must comply with national security regulations and demonstrate clear pathways toward European and allied technological sovereignty.

QBN WG Quantum Technologies for Defence & Security

The QBN Working Group Quantum Technologies for Defence & Security (WG QDS) serves as the strategic bridge between deep-tech innovators, ministries of defence, and military stakeholders. Backed by a powerful network of over 70 quantum vendors and defence primes, alongside 20+ public institutions and international MoDs, we help dual-use quantum companies navigate complex regulations. Together, we translate high-level defence policy into actionable steps, lower compliance and integration barriers for SMEs, design clear product-to-capability roadmaps, and facilitate high-trust ecosystem matchmaking.
