BRATISLAVA — Slovakia has approved plans to expand its fleet of F-16 fighter aircraft, a decision that has triggered criticism from opposition parties over the cost and the government’s wider defence priorities.

The government’s decision was reported on September 10, 2026, with opposition parties KDH and PS demanding greater transparency over the purchase and its long-term financial impact.

The planned acquisition involves four additional F-16 aircraft, with the reported allocation reaching hundreds of millions of euros. Opposition lawmakers have questioned whether the estimated cost is realistic and have called on Defence Minister Robert Kaliňák to explain why the additional aircraft should currently be considered a priority.

The debate comes as Slovakia continues to reassess its military capabilities and defence requirements following Russia’s war against Ukraine. NATO members across Europe have been reviewing their air-defence and military capabilities, increasing pressure on governments to modernize ageing equipment.

Supporters of the acquisition argue that additional modern fighter aircraft would strengthen Slovakia’s air-defence capabilities and improve its contribution to NATO. A larger F-16 fleet could also simplify training, maintenance and logistical arrangements because the country already operates the same aircraft type.

Opposition parties, however, have raised concerns about the wider financial implications. They want the government to provide a clearer breakdown of the purchase price, operating costs and the effect of the programme on other military priorities.

The controversy illustrates the difficult choices facing European governments as defence budgets increase. Modern fighter aircraft require not only the initial purchase investment but also long-term spending on weapons, maintenance, training, infrastructure and personnel.

Slovakia is therefore expected to face continued political debate over how its defence budget should be distributed among air power, ground forces, air defence and other military capabilities.

The government’s decision represents another step in Slovakia’s effort to strengthen its armed forces, while the opposition is demanding detailed financial justification before the country commits further resources.
