Ukraine now produces a kind of object that is almost unknown elsewhere: a weapon nobody is allowed to call complete. It leaves the workshop, goes to the front, and within a week the people who built it are changing it again.
An executive at TechEx, one of the country’s major makers of fiber-optic and interceptor drones, explained the rule to Business Insider’s Sinéad Baker. He gave only his first name, Oleg, for safety reasons. “There will never be a moment when you just build a product, and it’s just good,” he said. A company that “just stays with one single product,” he added, would within about three months find it “outdated, and nobody will use it.”
Three months. In Western defense ministries, that is roughly the time it takes to schedule a meeting about a requirement.
The enemy builds the countermeasure
TechEx updates its drones every week. Sometimes the change is large. Sometimes it is a few millimeters, or a few grams. Oleg described the logic of this war in one sentence: “when you build a good product, the enemy builds the countermeasure.” There is only one answer to that. “You need to work constantly.”
Other firms give similar numbers. Frontline Robotics says soldiers send it feedback around the clock and that it makes small changes to its products up to 20 times a month, which works out to about one every day and a half, with major updates roughly every six months. Ark Robotics says it may make about half a dozen different changes to a product over a few weeks. Many companies and soldiers say that without such updates their equipment could become useless on the battlefield within weeks. Each side’s newest machine is the other side’s next problem, in the same contest that has brought AI-guided gun turrets into the air war against Russia’s fastest drones.
The companies plan for this from the start. They build their products to be modular and software-first, so a change can be pushed remotely and quickly without redesigning or rebuilding the machine from scratch.
A phone call from the field
The chain between factory and soldier is short and informal, and nobody in it waits for permission. Companies text soldiers, message them on WhatsApp and video-call them while they are in the field. Requests and complaints flow upward from the units, not downward from a ministry. TechEx’s technical support department, Oleg said, works with more than 100 units. Ukrainian firms often send employees close to the front lines to collect feedback and help with repairs and upgrades, and those fixes are then built back into the product. Soldiers often surprise the makers with the ways they use or modify their gear, and those surprises shape what gets built next.
The other model
The Western way is slower. A design is matured and tested before production, then built in fairly stable batches for years, and changes wait for scheduled upgrades. Feedback usually travels up a formal chain rather than coming straight from the soldier using the weapon. A RUSI commentary published last December described Western systems as “treated as indivisible wholes, with procurement cycles often stretching over 10 to 20 years and upgrades requiring entire programme restructurings,” an approach that, it said, “treats innovation as a rare event rather than a continuous process.” The same paper put Ukraine’s drone output at an estimated 3,000 to 5,000 in 2022 and more than 2.2 million by 2024, with 4.5 million projected for 2025.
Some in the West are paying attention. Many Western companies are starting to change their processes, especially those whose products are used in Ukraine. Gen. Alexus Grynkewich of the US Air Force, NATO’s Supreme Allied Commander Europe, told Business Insider earlier this year that the alliance wants the same battlefield feedback loop Ukraine has and that allies are working on it. In August 2025 he had already described the problem to a defense industry audience: “If a Ukrainian brigade flies a drone on Monday, it might work — but by Wednesday, it might not, because of the robust electronic warfare environment or changes in adversary tactics.” This autumn, Al Jazeera reported, he presented a NATO plan against Russia, called “block, blunt, break,” which he said draws on lessons from the front in Ukraine.
Grand institutions can always learn. Their difficulty is learning at the speed of the people who are being shot at.
The price of a moving target
Constant revision has a cost, and the Ukrainians say so openly. A weapon that keeps changing is much harder to mass-produce. Achi, chief executive of the Ukrainian-Estonian robot, drone and software company Ark Robotics, has said that when “talking about scale manufacturing, any change comes at a very high price,” and that changes can slow production or stop it altogether. He still sees no choice. “You cannot afford not to be able to make changes,” he said. So manufacturers try to guess what the battlefield will need next while keeping their production lines running.
This is an old tension, now running at wartime speed. A factory needs a fixed drawing, and the war keeps making that drawing obsolete. The Ukrainian makers have chosen to keep the drawing open and pay the cost in efficiency, because the alternative is a weapon that arrives at the front already out of date.
Oleg’s advice for Ukraine’s European partners, repeated by other Ukrainian companies and officials, is to prepare for permanent adaptation. He also warned against comfortable assumptions about the enemy. Russia, he said, is “really good at technology” and at producing countermeasures to even Ukraine’s best weapons. “They’re being underestimated by a lot of people.”
