AI demand drives fiber shortage, squeezing Ukrainian drone supply chains

The rapid expansion of AI data centres is creating a severe shortage of fibre optic cables, which is directly impacting Ukraine’s capacity to manufacture jam-proof military drones. This supply chain pressure stems from competing industrial demands that have driven up costs and restricted access to critical materials for defence firms.The cost of making military drones is rising sharply because the same cables used for AI computers are in short supply globally.

The evidence

according to the published report, BlueBird Tech, a Ukrainian drone manufacturer, faces significant hurdles in securing fibre optic spools.reported A research and development representative for the company told Ars Technica that fibre optic cable prices have increased by a factor of six to ten over the past couple of years. This price surge is attributed to the AI data centre buildout absorbing a large portion of the global supply.

These drones can operate at ranges of up to 62 miles.reported However, Ukraine’s ability to scale production is constrained by its limited access to raw materials compared to its adversary.

In contrast, Russia imported 328,000 miles during the same period. Estimates suggest Russia acquired 37 million miles of fibre throughout 2025, representing more than 10% of global production.

The decision

The disparity in acquisition volumes highlights how geopolitical positioning and supply chain dynamics influence military production capabilities. Russia’s land border with China facilitates easier access to fibre optic materials, which remain primarily sourced from Chinese manufacturers. Ukraine faces additional barriers, including outright refusals from some Chinese companies to sell fibre optic cables.

What the evidence means

Ukraine’s reliance on Chinese suppliers creates a vulnerable dependency in its defence manufacturing sector. While alternative suppliers exist in other countries, they involve intermediaries and variable pricing, with China remaining the dominant source. The global nature of the shortage, estimated at 111 million miles, means that diversifying suppliers offers limited relief for Ukrainian manufacturers.reported

What builders can do with it

Developers and engineers working on fibre-optic tethered drones must account for extreme supply volatility and cost inflation. The documented six-to-ten-fold price increase suggests that hardware designs relying on long cable lengths face significant economic constraints. Builders cannot assume stable access to standard fibre spools, as global demand from AI infrastructure competes directly with defence manufacturing needs.

The limited range of 62 miles per drone, combined with supply shortages, indicates that operational planning must prioritise cable efficiency.reported Engineers may need to explore alternative tether materials or shorter-range designs if fibre remains scarce. The inability to train personnel on domestic manufacturing due to limited practice materials further restricts local production scaling.
