What Missiles Did Ukraine's New Shershen Air Defense System Use Against Banshee Jet Drones, and Could It Counter Gerans?

Ukraine's counter-drone problem has quietly split into two distinct wars. The first is against slow, propeller-driven Shahed-136 derivatives, where gun trucks, electronic warfare, and even small-arms fire have proven adequate. The second is against jet-powered Geran-4 and Geran-5 variants, which fly faster and higher, compressing engagement windows and pushing legacy short-range air defense to its kinematic limits. The Shershen system, revealed by Defense Express to have used missiles against Banshee jet drones, matters less as a single vehicle and more as evidence that Kyiv is fielding a dedicated layer for that second war.

The mechanics of the problem are straightforward. A jet-powered one-way attack UAV traveling at several hundred kilometers per hour and at altitudes above small-caliber gun range cannot be reliably serviced by the ZU-23 and Gepard-class systems that anchor Ukraine's mobile counter-drone teams. Infrared MANPADS can reach it, but each shot costs hundreds of thousands of dollars and the seeker must acquire a small, relatively cool target against ground clutter. Radar-guided short-range missiles solve the accuracy problem but historically cost more than the drone. That cost-exchange ratio is the central constraint: intercepting a cheap jet drone with an expensive missile is a losing arithmetic unless the interceptor is cheap, the launcher is reusable, and the sensor cueing is shared across a network.

Shershen appears designed around that logic. It is a mobile platform, which implies it can be dispersed to cover approach corridors rather than fixed to cities, and its use of missiles against Banshee targets suggests a fire-control chain capable of tracking fast, low-radar-cross-section objects. The specific missile matters enormously. If it is a Western short-range product, Ukraine gains capability but remains dependent on foreign production and export approvals. If it is a Ukrainian adaptation, whether a repurposed air-to-air missile or a new surface-launched interceptor, it points to a domestic industrial pathway that can scale without waiting on allied stockpiles. Defense Express has not fully resolved that question, and the answer determines whether Shershen is a stopgap or a template.
