Europe can backfill the shells, not the enablers
Shell production is a factory problem and it is being solved. Satellites, targeting and deep logistics are not, and cannot be bought inside a single budget cycle.
There is a comfortable version of the argument in which Europe simply pays more and the gap closes. It is comfortable because money is the easiest input to promise, and the least binding constraint in the specific places that matter.
What money buys quickly
Artillery ammunition, drones, small vehicles and short-range air defence respond to capital within a year or two, because the limiting factors are production lines, energetics supply and skilled shifts. All three are expandable given firm multi-year orders, and the orders have started to arrive.
What money does not buy quickly
Persistent overhead surveillance, secure long-haul communications, electronic warfare at theatre scale, and the analytic infrastructure that turns raw collection into targets in minutes rather than days. These are systems of systems built over decades, and the constraint is trained people and integration, not silicon.
A European army can be equipped in five years. A European targeting enterprise takes longer, and nobody has started the clock.
The awkward middle
The middle case is the dangerous one: an alliance with enough capability to sustain a defensive line and not enough to deter the next attempt. That posture invites probing precisely because it is visibly incomplete, and it absorbs budget without ever reaching the threshold where the deterrent works.
What to watch
Look for shared satellite constellations with committed launch schedules, joint munitions plants breaking ground, and any agreement that pools targeting data across national systems. Those are the load-bearing items. Headline percentage-of-GDP pledges are not, because they are satisfied by pensions, salaries and infrastructure well before they buy a single enabler.
