Can Ukraine’s newly shown Koral become home-built answer to Patriot? Expert evaluates system displayed at Poland’s MSPO expo

Ukraine's newly shown Koral missile could become a home-built answer to the Patriot in addition to the "Freya" project. However, the system has yet to prove it can stop Russian ballistic missiles, Ivan Kyrychevsky, an arms expert at Defense Express and a soldier in the 413th REID regiment of the Unmanned Systems Forces, said on a YouTube broadcast.

Currently, the PAC-3 version of the Patriot is the only weapon in Ukraine's arsenal that reliably stops Russia's maneuvering Iskander ballistic missiles, and its interceptors are scarce, costly, and rationed for Ukraine by the US.

But in the podcast, Kyrychevsky places Koral, on the data available so far, at roughly the older PAC-2 level. A PAC-2-class interceptor can handle aircraft and simpler ballistic targets, yet it is not the ideal tool against the fast, maneuvering Iskander and Kinzhal that do the most damage. That leaves Koral a hedge against dependence, not a replacement.

The missile sits a tier below Patriot

Kyrychevsky based the judgment on photos released at the expo. The Koral missile lacks the gas-dynamic surfaces that would let it maneuver in flight, he said, and it carries a different warhead from the "hit-to-kill" round on the PAC-3. He did not treat that as disqualifying.

"We are in a situation where we do not just need means against ballistics, but means of at least some technological level," he said.

Cost tilts Ukraine toward its own missile

The economics push in the same direction. A PAC-3 interceptor runs about $10 million for export, and Kyrychevsky noted that even the US Army finds the missiles expensive to spend at the rate the fighting around Iran has demanded.

"We are better off building our own analog of the Patriot, even a mediocre one, than staying dependent on the regularity of external deliveries," he believes.

Winter still hinges on the Patriot

For all that, Kyrychevsky was blunt about the near term. Koral still needs to be tested against Russian ballistic missiles, even experimentally, to confirm its claimed performance, and power cuts at the plants that build it could slow production.

“My assessment for now is roughly this: hopefully, we’ll be able to put the ‘Koral’ to the test against Russian ballistic missiles on an experimental basis," he said.

This winter, he said, Ukraine will need Patriot interceptors regardless of whether it develops its own. Work on Koral began in 2016, and the system was first shown in 2021, a fast pace for a weapon of its kind, and a separate European project, Freya, is advancing on a parallel track.

In July, President Volodymyr Zelenskyy said that Ukraine, in cooperation with other European countries, was working on an anti-ballistic missile defense system called “Freya". It is intended to serve as a cheaper and more widely deployable alternative to Patriot air defense systems.

Zelenskyy noted that, in theory, Ukraine could develop “Freya” on its own, but doing so would take significantly more time — potentially years. The system would require not only a missile and launcher, but also radars, command-and-control systems, and many other components. Even with European partners, the process will not be quick.
