Iran is using the war in Ukraine to make its attack drones deadlier. Iran has been refining its Shahed-107 kamikaze drones based on the experience of the war in Ukraine, military analyst Oleksandr Kovalenko said.

Ukraine has become the testing ground where Iran improves the weapons, and Russia then fires at it. The Shahed-107's warheads have received additional shrapnel elements, and a detailed aerodynamic study shows a significant improvement in the drone's structure, Kovalenko explains.

The Shahed is being upgraded from combat experience

Kovalenko said the modifications come directly from how the drones perform in Ukraine. The warheads now carry extra fragmentation elements, increasing their lethality against people and soft targets, and the airframe's aerodynamics have been reworked.

A new loitering munition may be coming

Kovalenko also warned about a weapon already appearing over Ukraine. Karar drones have recently begun reaching Ukraine, not yet on a large scale, but enough to cause some confusion in identifying the weapon. He said he would not be surprised if they appear more widely soon.

He described its specifications.

"The Karar is a loitering munition, more a flying bomb than a drone by classification, equipped with a DLE 111 gasoline engine, with a range of about 300 kilometers on a 28-liter tank and a 15-kilogram warhead," Kovalenko said.

He called it an extremely cheap means of terror for the middle rear zone.

The warning is about the rear

Kovalenko's concern is where such a weapon reaches. A cheap loitering munition with a 300-kilometer range could strike areas well behind the front that have been relatively safe, extending the threat deeper into Ukraine.

Kovalenko framed the weapon's arrival in stark terms, saying that when it appears, people should simply accept what will happen, and declining even to name the region where he expects it to appear. That is his characterization: a single analyst's warning about a weapon whose wider use he anticipates but that has not yet reached scale. EP cannot independently verify Karar's specifications or its deployment.
