Critical Infrastructure Investments (Ukrainian Lessons)

What infrastructure keeps an army fighting under drone attack?

Chapter summary

Ukraine shows that factories, repair and communications must survive constant attack. The chapter costs three infrastructure programmes.

Key takeaways

  1. 1

    Underground and hardened manufacturing: €3–5B over 24–36 months.

  2. 2

    Rapid repair with mobile 3D printing: €1–2B over 12–24 months, with 72-hour vehicle recovery.

  3. 3

    Resilient communications integrated with space: €5–8B.

3.1 Underground/Hardened Manufacturing

Ukrainian Experience:

  • Distributed production. Small facilities survive strikes
  • Underground facilities. Critical for ammunition, drones
  • Mobile production. Relocatable manufacturing units

European Requirement:

  • Hardened ammunition production facilities
  • Underground drone manufacturing
  • Dispersed critical component production
  • Rapid reconstitution capability

Investment Priority. HIGH

  • Investment. €3-5B
  • Timeline. 24-36 months
  • Focus. Critical production hardening

3.2 Rapid Battlefield Repair & Sustainment

Ukrainian Innovation:

  • Mobile repair units. 72-hour vehicle recovery
  • 3D printing: Battlefield spare parts production
  • Modular systems. Rapid component replacement

Technology Requirements:

  • Mobile 3D printing (metal, composites)
  • AI-powered diagnostics
  • Modular vehicle/drone design
  • Forward-deployed maintenance

Investment Priority. MEDIUM-HIGH

  • Investment. €1-2B
  • Timeline. 12-24 months

3.3 Resilient Communications Infrastructure

Combat Lessons:

  • Starlink dependence. Critical vulnerability
  • Mesh networks. Essential redundancy
  • Fiber optic. Jam-proof drone control
  • Quantum encryption. Future-proof security

Critical Investments:

  • European satellite constellation (IRIS² acceleration)
  • Tactical mesh network systems
  • Fiber-optic drone control technology
  • Quantum communication infrastructure

Investment Priority. CRITICAL

  • Investment. €5-8B (integrated with space programs)
  • Timeline. 24-36 months for initial capability
