Belgium Receives First Four F-35A Jets at Florennes Air Base and Preparing to Send F-16s to Ukraine

On Monday, October 13, 2025, Belgium received its first four F-35A Lightning II fighter jets at Florennes Air Base, marking a significant milestone in the country's defense modernization efforts. This delivery initiates the replacement of Belgium's aging fleet of F-16s with advanced fifth-generation aircraft, enhancing its capabilities within NATO's defense framework.

F-35A Acquisition Deal and Budget

In October 2018, Belgium officially selected the F-35A to replace its fleet of approximately 54 F-16s. The total purchasing price for the aircraft and its support until 2030 was $4.32 billion, $648 million less than the initially budgeted $4.97 billion.

In July 2025, Belgium committed to purchasing an additional 11 F-35A jets, bringing the total fleet to 45. The investment for these 11 aircraft is estimated to cost between $1.08 billion and $1.62 billion, with an average unit price of around $86.4 million, including support and additional training.

To support these acquisitions, Belgium's defense budget is set to rise from $11.66 billion to $19.66 billion, totaling $150.12 billion over the next decade.

F-35A Arrival at Florennes Air Base

The four F-35As, manufactured by Lockheed Martin, arrived at Florennes Air Base in Wallonia, Belgium, as part of the Belgian Air Component's transition to modernize its fleet. This transition is essential for maintaining operational effectiveness and interoperability with NATO allies. The aircraft were delivered from Lockheed Martin's production facility in Fort Worth, Texas, to Florennes Air Base.

Impact on F-16 Transfers to Ukraine

The arrival of the F-35As enables Belgium to fulfill its commitment to transfer 30 F-16 fighter jets to Ukraine by 2028. This decision aligns with NATO's collective defense objectives and supports Ukraine's defense capabilities amid ongoing regional tensions. The transfer of these aircraft is expected to commence in late 2025, following the completion of necessary training and logistical preparations.

Belgium's Commitment to NATO and Ukraine

Belgium's acquisition of the F-35A jets underscores its dedication to enhancing its defense posture and fulfilling international commitments. The decision to transfer F-16s to Ukraine reflects Belgium's support for NATO allies and its role in contributing to regional stability. The phased delivery of these aircraft will be coordinated to ensure seamless integration into the Ukrainian Air Force's operations.

Future Outlook

Looking ahead, Belgium plans to continue its modernization efforts by acquiring additional F-35As, with discussions underway to expand the fleet further. This strategic move aims to bolster Belgium's defense capabilities and maintain its contributions to NATO's collective security initiatives.

In conclusion, the arrival of the F-35A jets at Florennes Air Base represents a pivotal development in Belgium's defense strategy, facilitating the planned transfer of F-16s to Ukraine and reinforcing Belgium's commitment to NATO and regional security.
