- Thousands of perfectly functional drones rendered useless after frequencies were heavily jammed
- Ukrainian workshops now rebuild abandoned drones faster than factories deliver replacements
- ReDrone recovers engines and controllers from destroyed aircraft for repair on the battlefield
Thousands of drones parked in Ukrainian warehouses are not broken, but they cannot fly in current combat conditions because their components are already obsolete.
The problem arises from the time lag between large government contracts and the rapidly changing electronic warfare environment on the front lines.
When the enemy discovers a drone’s operating frequency and begins jamming it, the pilot loses the video signal and the aircraft becomes effectively blind.
A lifeline for obsolete drones
ReDrone, a workshop created by the Sternenko Community Foundation, now refurbishes up to 2,000 drones per month (24,000 per year), giving a second life to obsolete equipment in active combat.
The state purchases 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 had remained usable for six months in 2023 now only remains relevant for three months, or even less in certain areas.
ReDrone craftsmen solve this problem by replacing outdated video transmitters with newer components operating on different, less suppressed frequencies.
Combat teams first organized informal exchanges through military chat rooms, transferring drones with compromised frequencies to units where those bands still operated.
Over time, some units have accumulated hundreds of drones in their warehouses, ready to trade them in exchange for rare components like updated video transmitters.
This barter system gradually evolved into the ReDrone workshop, which now processes more than a thousand drones each month from its dedicated facility.
The workshop strips drones with poor-quality cells or faulty fiber optic spools for their valuable internal components, using surviving motors, controllers, and other parts as donors to repair other equipment.
How to improve drone repairability
The breakdown in communication begins when manufacturers sign big contracts and no longer hear from troops using their equipment.
Decentralized supply is useful, but buyers without combat experience often choose the cheapest offering over the most combat-worthy design.
Manufacturers must stay in constant contact with military units because conditions change faster than a single feedback loop can keep up.
Logistics planning must take into account real delays and quality control cannot stop at the factory gate.
The Sternenko Foundation requires manufacturers to replace defective drones free of charge, and the state should apply the same standards in all contracts.
Manufacturers must also create ecosystems, not just individual drones that can be quickly isolated, because 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 a few months.
The state should create spaces where manufacturers can develop common standards for connector types and frequency bands, which would allow a pilot to switch from one transmitter to another without having to completely dismantle a workshop.
ReDrone’s work highlights a fundamental flaw: manufacturers build proprietary systems without standardization across brands.
This is the opposite of the modularity defended for years for consumer electronics.
Although open standards can pose security concerns, they are often seen as a necessary risk to maintain technological superiority.
This will enable field repairs, reduce waste and end the cycle of disposable drones that workshops like ReDrone are forced to constantly refurbish.
