After Russia’s heaviest winter strike campaign, Ukraine’s Air Force has acknowledged a shortage of air-defense missiles. Some launchers assigned to units and batteries are now only partially loaded, while missile stocks for several systems remain limited.
This does not mean Ukraine’s skies are unprotected. The country has developed mobile fire groups, interceptor drones, electronic warfare systems and localized defenses against Shahed-type drones. But against cruise missiles, ballistic missiles and complex combined attacks, Ukraine still depends heavily on Western air-defense systems.
According to Daycom’s earlier analysis, the shortage of missiles for NASAMS, IRIS-T and Patriot has become one of the most sensitive pressure points in a war of attrition. In such a war, the launcher itself is not enough. What matters is the uninterrupted flow of ammunition to keep it alive as a shield.
Russia understands that arithmetic well. Mass strikes involving hundreds of drones and dozens of missiles are designed not only to damage power plants, ports, military sites and urban infrastructure. They also force Ukraine to spend expensive and limited interceptor missiles.
That is why air defense has become one of the war’s central fronts. On the ground, the line of contact may move slowly. In the sky, resources are consumed every night. Each launch becomes a decision between defending a city, a power station, a military facility or saving missiles for the next wave.
Ukrainian forces have learned to shoot down a large share of Russian drones with cheaper tools. Machine-gun teams, mobile crews, electronic warfare, anti-aircraft guns and new interceptor drones all play a role against Shahed-type systems. But that network cannot replace missile defense when more complex targets arrive.
The main problem is not any single weapon, but the layering of Russian attacks. Moscow combines drones, cruise missiles, ballistic missiles, decoys and guided aerial bombs in shifting patterns. This forces Ukraine to conserve missiles while still trying to prevent strikes on critical infrastructure.
Western systems remain the backbone of that defense. NASAMS and IRIS-T protect important medium-range sectors, Patriot is essential against ballistic missiles, and other systems complete the layered shield. But the shield is only as strong as the missile supply behind it.
Ukraine has faced delays and disruptions in allied deliveries throughout the war. Now the pressure is growing because the same types of air-defense ammunition are in demand in other conflicts. As Western systems are used extensively in the Middle East, Ukraine’s need becomes part of a wider global shortage.
That creates a harsh dependency on the political calendars of allies. An interceptor must arrive before a night attack, not after negotiations conclude. In this kind of war, a delay of even a few days can mean a damaged power plant, a destroyed transformer or dozens of civilian deaths.
It is telling that Ukraine sometimes has to ask partners not for hundreds of missiles, but for five or ten at a time for specific systems. In the language of peacetime bureaucracy, that sounds like a logistical detail. In wartime reality, it can be the difference between an intercepted strike and a breached defense.
Russia’s air campaign also has a psychological dimension. When Ukraine is forced to conserve missiles, Moscow tries to impose an impossible choice: what to defend today, and what to leave exposed tomorrow. That logic drains not only warehouses, but the entire command system responsible for protection.
For civilians, the shortage is felt through air-raid alerts, explosions, blackouts and the expectation of new strikes. For the military, it means difficult decisions inside batteries and command posts. For allies, it raises a harder question: whether they are prepared to support Ukraine not with occasional packages, but with an industrial rhythm.
That industrial rhythm is now decisive. Russia has bet on mass drone production and regular combined strikes. Ukraine and its partners must answer not only with individual systems, but with long-term production of missiles, spare parts, radars and interceptors.
The shortage of air-defense missiles is not a narrow technical problem. It is a question of city survival, grid stability, front-line protection and trust in Western guarantees. If the air shield weakens, Russia gains more room for terror and coercion.
Ukraine has shown that innovation can compensate for part of the shortage. But no improvisation can replace stocks for Patriot, NASAMS or IRIS-T when ballistic missiles or complex missile combinations are incoming. Creativity buys time. It does not eliminate the need for ammunition.
The central conclusion is stark: in an air war, the outcome is shaped not only by the quality of the systems, but by the depth of the stockpiles. An empty launcher cannot stop a missile. A half-empty shield over a country is an invitation to the next wave of strikes.
