The Czech Army’s effort to modernize its T-72M4CZ tanks has effectively collapsed. According to Novinky, which cited the Czech Ministry of Defence, the program hit insurmountable technical obstacles that engineers were unable to resolve. The ministry acknowledged that critical components of the fire-control system had degraded to a point where neither repairs nor replacements were possible.

In its statement, the ministry said the failure of these essential fire-control elements rendered the T-72M4CZs «virtually unfit for service,» pushing the project toward cancellation. The army had originally planned to transfer the upgraded tanks to Ukraine once they entered service.

Novinky reports that the tanks underwent a full series of mandatory acceptance tests over the summer and autumn. None of the trials met the required standards. The decisive setback emerged during rectification — the accuracy-calibration stage — where electronic modules within the fire-control system malfunctioned repeatedly. The Italian manufacturer later confirmed that restoring these components was technically impossible.

As a result, the vehicles failed to meet operational benchmarks and turned into a heavy financial burden. Bringing the tanks up to even a basic operational level would require new investments into the same fire-control architecture, driving up the cost of an already outdated platform and delaying any potential delivery by at least two years. The Czech Ministry of Defence concluded that such spending made no sense.

Novinky also recalls that the decision to upgrade roughly 30 units of the T-72M4CZ fleet was made before the Ukraine conflict and before Germany offered Prague free Leopard 2A4 tanks. At that time, the Czech Army lacked the budget to procure modern armor, and updating its own fleet seemed the only way to keep its tank forces operational.
