> If there was an actual war on, and a nation was taking both combat and operational losses - then 10 or 20 per year hardly amounts to squat.

That is correct. But you want to ramp up production without too much over-investment. It is not certain, at the moment, that this conflict will devolve to a full-blown world war. So if you invest in a factory to produce 1000 radars a year, what good is it if the conflict putters out?

There is zero solidarity on a European level for common investments in armament, with most countries lining up for US-made equipment instead of investing in ramping-up their own production. So that also means that the financial burden of ramping-up arms production is also not shared.
