The Ukrainian company DeViro has upgraded the Bulava ranged munition, increasing its range and warhead power. This is reported by Militarnyi.
The new product was shown at the Defense Tech Valley 2025 exhibition. It is noted that the ammunition now flies not 55 km, but as much as 100 km, with a guaranteed flight time of 75 minutes (it was 50 minutes). Its warhead now weighs 5 kg (it was 3.6 kg), and the wings have become 7 cm longer.
"A warhead weighing 3.6 kg can disable, damage, and sometimes destroy a target, but increasing the weight allows you to multiply the chance that a second strike will not be needed," said the company's technical director, Denys Chumachenko.
At the same time, the production of the previous version is not stopped, and the version with a 5 kg warhead will still be available on separate orders from units. According to the developers, there are seven types of warheads in both versions, including fragmentation, thermobaric, cumulative, etc. However, they are not interchangeable, because accurate weight centering is important for X-shaped UAVs.
"Warheads are not interchangeable in terms of mass and centering — replacement in the field is often impossible. Therefore, final adjustment and confirmation of compatibility are carried out at the factory. At the ordering stage, the military can form a set, for example, 5 thermal bars and 10 fragmentation ones, and receive them in a set," the developers noted.
In addition, thermal imaging optics for night operation have been created for the updated Bulava. It is also noted that Ukrainian engines are already used in drones, and the company has almost abandoned the purchase of ready-made controllers. Their production has been established in the development department. The next step is planned to switch to domestic telemetry devices.
In addition, the company has improved the Leleka-100M2R reconnaissance repeater, which provides communication for the Bulava and also searches for targets for it. In particular, the range of this UAV has now been increased from three to five hours.
Another innovation was the optical module, which received a multi-sensor platform with fixed lenses instead of a motorized lens. This improved image quality at the expense of better camera stabilization. The old "Storks" had problems with focus after hard landings.
"We've done a lot of work on bugs. There used to be memes about a cat shaking and everyone wrote 'this is Leleka-100' [meaning poor camera stabilization]. Now this is gone, everyone can apply for a software update," the company said.
At the same time, the modernizations did not increase the prices of drones.
We remind you that the exhibition also presents a robotic amphibian drone and a ground robotic complex that performs "heavy" logistics and attack tasks.
