Standing assessment
Current condition
Low confidenceAs of
Reported interception against ballistic and quasi-ballistic missiles has been low since the second half of 2025, and the decline predates the interceptor-exhaustion claims made in mid-2026.
Ukraine does not publish how many incoming missiles were engaged, so the published rate has no denominator. Three explanations remain live — Russian trajectory and decoy adaptation, interceptor scarcity, and engagement choice — and this module ranks none of them.

Opened with the Analytical Note on Ukraine's four air wars, which set out the three explanations and the order-of-movement test that separates them.

Why it matters
The three explanations lead to three different responses: adaptation calls for new tactics and sensors, scarcity for supply, engagement choice for nothing at all. Reading the rate without knowing which is at work turns a measurement into an argument for whichever policy the reader already favoured. The question is answerable because the explanations imply different orders in which the rate and the supply instruments move.
Observables3 named · “met” describes evidence, not success
01Test
Whether the rate moves before or after a concluded supply instrument
Recovery without resupply favours the adaptation reading; resupply without recovery favours it more strongly still. A rate that moves with deliveries favours scarcity.
02Test
A published engagement count
Any official series stating how many incoming ballistic missiles were engaged, which is the denominator the published rate lacks.
03Test
Documented trajectory or decoy adaptation in Russian packages
Reporting from Ukrainian air defence or independent analysts that names a specific change in terminal behaviour, decoys or salvo construction against the Patriot-class lane.
What would change the assessment3 thresholds · the boundaries as the record states them, none with a number
A published interception rate that recovers over two months with no concluded supply instrument behind it
Would meanretires scarcity as the leading explanation.
A rate that recovers within a month of a confirmed delivery
Would meanretires adaptation as the leading explanation.
A published engagement denominator
Would meanchanges what the rate measures at all.
What remains unknown
- No engagement count is published, so the rate has no denominator and the three explanations cannot be separated from the published series alone.
- Interceptor stock levels are not published by any party.
Readings the evidence also supports
- The published rate reflects reporting practice — which strikes are reported at all — rather than defensive performance.
Listed because the record's own assessment is not the only one its sources permit — not as a hedge on the assessment above.
