Russian forces attacked the Kharkiv region with aviation bombs equipped with universal glide and correction module (UGCM), capable of flying up to 95 kilometers and reaching not only Kharkiv but also communities south of the city.
* UGCM (Universal Glide and Correction Module) is a Russian combat module that converts ordinary free-falling aviation bombs into guided bombs, increasing their range and accuracy.
This was reported by Spartak Borisenko, head of the Kharkiv Regional Prosecutor’s Office.
He explained that the first use of this upgraded aviation weapon occurred at the end of May.
“On May 31, 2025, around 10:30 AM, from the settlement of Tomarivka in Russia’s Belgorod region, four launches of guided aviation bombs with extended-range glide and correction modules — that is, long-range UGCM — were made from a Su-34 aircraft. This was the first use of this module in Kharkiv region. Also in May, according to operational information, similar bombs were used in Sumy region,” Borisenko said.
The unified glide and correction module is mostly attached by the Russians to high-explosive aviation bombs.
“If last year the average distance from launch to target was 60-80 kilometers, now we can say they are using these guided aviation bombs at distances up to 95 kilometers. We understand they are still testing them. The range may increase further. If we open a map, we can see that from the launch area near Tomarivka, any place in Kharkiv can be hit by these guided aviation bombs,” the prosecutor said.
He clarified that the modules can fly further thanks to heavier mounting systems, longer wings, and new control developments.
“Analysis of fragments found during site inspections by prosecutors and investigators shows the use of different, heavier mounting systems, larger wings, and also the latest control technologies for these wings, allowing them to cover 95 kilometers,” Borisenko said.
He noted that the launch speed and altitude for bombs with the new modules remain unchanged:
“Launches are made from 9,000 meters altitude from Su-34 aircraft. The guided bombs’ speed is 700-800 kilometers per hour.”
On May 31, the Kharkiv Regional Prosecutor’s Office reported morning airstrikes on Kharkiv suburbs with UGCM bombs. According to their data, in the village of Vasyshcheve, buildings and warehouse facilities of a private enterprise were damaged. Three people were injured: a 22-year-old woman and two men aged 64 and 57. In the village of Bezliudivka, over 10 homes were damaged. Two women aged 74 and 66 were wounded.
