Converting car plants to make military drones will fail, warns Japan defence titan

Mitsubishi Heavy Industries chief says tactic risks being ‘enormous waste’ of taxpayers’ money

Why this matters
Why now

The increased geopolitical tensions and lessons from ongoing conflicts are pushing nations to rapidly expand defence capabilities, leading to discussions around industrial conversion for military production.

Why it’s important

A major defence industrialist's warning highlights the complexities and potential inefficiencies of rapid, top-down industrial reorientation, especially concerning advanced technologies like drones.

What changes

The feasibility and cost-effectiveness of converting existing industrial infrastructure, particularly automotive plants, for modern defence production is now under critical scrutiny, challenging prior assumptions of quick pivots.

Winners
  • · Dedicated defence contractors
  • · Specialized drone manufacturers
  • · Defence industrial policy advisors
Losers
  • · Governments funding industrial conversion
  • · Automotive manufacturers attempting defence pivots
  • · Taxpayers
Second-order effects
Direct

Nations will reconsider the economic viability and technical challenges of industrial conversion for defence production.

Second

Increased investment in bespoke defence manufacturing capabilities and greenfield projects for drone production, rather than conversions.

Third

Potential for closer integration between defence ministries and established defence technology firms to strategize on capacity expansion, prioritizing specialized builds over general industrial repurposing.
