Russia built the missile. The West built much of its brain.

A Lansing Institute investigation alleges that Chinese-origin electronics and suppliers appear in the supply chain for Russian Kalibr and Kh-35U missiles. Its claims are investigative allegations, not court findings. Still, they illuminate the enforcement problem: dual-use chips, connectors and boards can travel through commercial distributors and third countries long before they become part of a weapon.

The flag painted on a missile tells you who launched it. It says far less about who made the components, or who could interrupt their journey.

This is the part the brochure is unlikely to discuss. The prime contractor appears to be the only supplier that matters. The actual control sits in the engine, electronics, software, ejection seat, raw material or certification held by a lower tier supplier. That is the control point hiding behind the headline fact: Russia built the missile.

For Russia, a platform is only as sovereign as its least replaceable part. That risk is easy to miss when the announcement stops at 'Russia built the missile'.

Control is usually exercised through procedure, not a cinematic red switch. The party holding the leverage can withdraw a component or its approval while leaving the main contract looking perfectly healthy. By the time the buyer is certain that the delay is political, the readiness loss has already begun. For Russia, the warning is captured by what followed: The West built much of its brain.

Run the failure as a tabletop exercise before it becomes a real one. Assume the controlling party decides to withdraw a component or its approval while leaving the main contract looking perfectly healthy. Who notices first? Who has authority to activate the alternative? How many days of usable stock remain? If the answers require a new committee, a new budget and a new contract, you do not yet have a fallback. The exercise has a concrete starting point in this case: Russia built the missile.

Do not ask whether the supplier is friendly. Ask questions that can be evidenced. Which drawings and test data would be needed to replace a blocked part? Can your own engineers certify a substitute without the original supplier? What inventory exists for components with geopolitical exposure?

Then test the fallback. Has the proposed alternative ever flown, fired or operated in the complete system? Which tier two and tier three suppliers have no qualified alternative? Where are export licences required after the initial sale? A plan that exists only in a slide deck will not become real because the crisis has arrived.

Resilience has to be purchased deliberately. The programme should treat the bill of materials as a sovereignty document, fund qualification of a second source before the first source becomes unavailable and secure technical data and interface information for critical parts. If those items are unfunded, the independence claim is unfunded too.

Price that exposure honestly. A cheaper bid with one unmanageable control point may be more expensive than a higher bid that preserves options. Acquisition teams are good at comparing purchase prices. They are less consistent at pricing the cost of a grounded fleet, an empty magazine or a capability that arrives after the political need has passed. The headline fact, 'Russia built the missile', should carry that exposure in its score.

Local content still has value. Jobs, skills and assembly experience matter. But none of them should be confused with the ability to redesign, certify and sustain the system without foreign consent. That distinction matters here: The West built much of its brain.

The final test for Russia is simple: can national engineers replace and certify the critical foreign part without waiting for a fresh political approval? If the honest answer begins with 'provided that somebody else agrees', that condition belongs on the first page of the procurement decision, not in an annex nobody reads. That risk is easy to miss when the announcement stops at 'Russia built the missile'.

The platform may remain physically in your hangar while the ability to operate it disappears one component at a time. The smallest foreign component can carry the largest political veto. That is what 'Russia built the missile' should force a buyer to test.
