- Thousands of perfectly functional drones were rendered useless after the frequencies were severely jammed
- Ukrainian workshops now rebuild abandoned drones faster than factories deliver replacements
- ReDrone salvages engines and controllers from destroyed aircraft for repairs on the battlefield
Thousands of drones sitting in Ukrainian warehouses are not destroyed, but they cannot fly in the current combat conditions because their components are already obsolete.
The problem stems from the time lag between large government contracts and the rapidly changing environment of frontline electronic warfare.
When the enemy figures out a drone’s operating frequency and begins jamming it, the pilot loses the video signal and the aircraft is effectively blinded.
A lifeline for obsolete UAVs
ReDrone, a workshop created by the Sternenko Community Foundation, now refurbishes up to 2,000 drones per month (24,000 annually), giving obsolete equipment a new life in active combat.
The government buys drones in massive batches of 10,000 to 20,000 units, but production and delivery take so long that battlefield conditions change completely before the equipment arrives.
A frequency that remained usable for six months in 2023 now remains relevant for only three months or even less in some areas.
ReDrone’s craftsmen solve this by replacing outdated video transmitters with newer components that operate on different, less suppressed frequencies.
Combat crews initially organized informal exchanges through military chat rooms and transmitted drones with compromised frequencies to units where these bands were still operating.
Over time, some entities accumulated hundreds of drones in their warehouses, ready to give them away in exchange for scarce components like updated video transmitters.
This exchange system gradually evolved into the ReDrone workshop, which now processes over a thousand drones every month from its dedicated facility.
The workshop removes drones with poor quality airframes or defective fiber optic coils for their valuable internal components, using motors, controllers and other surviving parts as donors to repair other equipment.
How to improve drone repairability
The breakdown in communication starts when manufacturers sign large contracts and then never hear from the troops using their equipment.
Decentralized procurement helps, but purchasers without combat experience often choose the cheapest bid over the most combat-worthy design.
Manufacturers must be in constant contact with military units because conditions change faster than a single feedback loop can track.
Logistics planning must account for real-world delays, and quality control cannot stop at the factory door.
The Sternenko Foundation requires manufacturers to replace defective drones at no cost, and the state should enforce the same standard across all contracts.
Manufacturers must also build ecosystems, not just individual drones, which can be quickly isolated, as a drone needs compatible ground stations, updated software and ongoing support to remain useful as electronic warfare tactics evolve.
Companies that sell sealed black boxes will see their products become obsolete in months.
The state should create space for manufacturers to develop common standards for connector types and frequency bands that would allow a pilot to change a transmitter from one drone to another without a full workshop demolition.
ReDrone’s work highlights a fundamental flaw: manufacturers build proprietary systems without standardization across brands.
This is the opposite of the modularity that has championed consumer electronics for years.
Although open standards can introduce security challenges, they are often seen as a necessary risk to maintain technological superiority.
It will allow repairs in the field, reduce waste and end the cycle of disposable drones that repair shops like ReDrone are forced to endlessly refurbish.
