In Ukraine, data centers facing increased attacks in recent weeks: Ex-official

Breaking Defense | Raashi Quattlebaum

Ukraine is facing a critical threat to its communications infrastructure following a surge in Russian drone and cyber strikes targeting domestic data centers. In late September 2026, Russian forces successfully struck the headquarters of Kyivstar and a major Vodafone Ukraine facility. These attacks have prompted President Volodymyr Zelenskyy to order urgent protective measures for the nation's digital networks.

To mitigate these aerial threats, former deputy defense minister Kateryna Chernohorenko advocated for expanding underground networks and boosting depleted air defense capabilities. However, critical bottlenecks persist. Ukrainian F-16 fighter jets, highly effective against Russian jet-powered Geran-5 drones, face severe maintenance delays in Belgium that keep nearly the entire fleet grounded. Without thousands of additional rounds and accelerated sustainment cycles, the country risks a severe shortage of operational fighter aircraft by the end of 2026, leaving vital digital infrastructure highly vulnerable to continued Russian aerial bombardment and cyber operations.

Comment

The severe maintenance backlog for Ukrainian F-16 fighter aircraft at Belgian facilities exposes a critical vulnerability in multinational defence sustainment pipelines. Relying on Sabena Engineering in Belgium, where turnaround times stretch to 40 weeks compared to the standard six-week cycle in the United States, severely restricts Kyiv's immediate air defence capacity. This logistical bottleneck directly impairs the interception of low-flying Russian Geran-5 jet-powered drones targeting critical telecommunications hubs.

The prolonged maintenance cycle stems from a lack of localised technical expertise and spare parts within Europe, forcing airframes to undergo extensive transit and administrative delays before servicing begins. Consequently, the operational availability of the Ukrainian F-16 fleet remains dependent on a fragile European commercial repair network rather than organic military depot capabilities. This structural dependency prevents the rapid generation of sorties required to protect vulnerable nodes like the Kyivstar headquarters.

Strategic Question for Discussion

If the F-16 maintenance backlog at Sabena Engineering continues at its current pace, does the model of relying on external European commercial depots for active combat sustainment break down entirely, or can localised workarounds compensate?

The current trajectory indicates that relying on distant commercial facilities like Sabena Engineering is unsustainable for high-intensity attrition warfare. My assessment is that without establishing forward-deployed, military-run maintenance hubs within Poland or western Ukraine, the operational availability of the F-16 fleet will degrade to a point where it cannot defend critical infrastructure. Consequently, Kyiv will be forced to rely almost exclusively on ground-based air defence systems, further depleting its scarce interceptor stockpiles.
