Industrial sovereignty: what the war economy actually demands of defence SMEs

The term war economy has become widespread in French public debate since 2022. On the industrial ground, it designates a constraint far more precise than the slogan suggests: produce more, faster, without degrading quality, with supply chains that are already under strain.

What this concretely changes for a sub-contractor SME

• Production rates that require requalifying secondary suppliers, sometimes less well-controlled
• Pressure on critical component stocks, particularly electronics
• Military qualification cycles that remain long, out of step with the stated operational urgency

The real bottleneck

It is rarely political will or the order book that limits the production ramp-up. It is actual industrial capacity: machine tools, qualified skills, specific components whose lead times are sometimes measured in years.

A transferable lesson

Civilian organisations managing critical supply chains have every reason to study how the defence industrial base manages this tension between stated urgency and real industrial lead times. The same asymmetry appears in many sectors under resilience constraints.

The war economy is not a slogan - it is a series of concrete industrial decisions, often invisible, that determine whether the announced sovereignty is actually sustainable.
