Czech Republic Accelerates F-35A Integration to Replace Gripens Fitghters and Modernize Its Air Force.
In 2024, the Czech Air Force took a strategic step with the acquisition and ongoing integration of fifth-generation F-35A Lightning II fighter jets. This program, with a total cost of approximately $5.62 billion, includes the purchase of 24 aircraft along with the necessary infrastructure for their maintenance and operation. This substantial investment, intended to replace the current fleet of JAS-39 Gripens, forms a central pillar in the modernization of the Czech Air Force and its alignment with NATO standards.

The decision to procure the F-35A reflects a strategic intent to significantly enhance the Czech Republic's air defense capabilities. Renowned for their stealth, advanced sensors, and ability to operate in highly contested environments, these fighter jets will provide the Czech Air Force with greater air superiority, reconnaissance, and precision strike capabilities. Major General Petr Čepelka, Commander of the Czech Air Force, noted that these aircraft will transform operational approaches while ensuring seamless interoperability with NATO’s integrated defense systems.
The F-35A Lightning II, developed by Lockheed Martin under the Joint Strike Fighter program, is a fifth-generation multirole fighter designed for air superiority, ground attack, and advanced reconnaissance missions. With optimized dimensions (15.7 m in length and a 10.7 m wingspan) and powered by the Pratt & Whitney F135-PW-100 engine, the aircraft can reach Mach 1.6 and a service ceiling of 15,240 m, with a combat radius of 2,220 km. Its stealth capabilities are supported by aerodynamic designs and an internal weapons bay, complemented by sensors such as the AN/APG-81 AESA radar and Distributed Aperture System (DAS), which provide comprehensive situational awareness. The cockpit includes a Helmet-Mounted Display System (HMDS), projecting critical data directly into the pilot's field of vision.
The F-35A is armed with an internal M61A2 Vulcan 20 mm cannon and can carry a range of air-to-air missiles (AIM-120 AMRAAM, AIM-9X Sidewinder) and air-to-ground munitions (GBU-31 JDAM, GBU-39 SDB, AGM-88 HARM). While its internal weapons bay maintains stealth during operations, the aircraft can also utilize six external hardpoints for additional payloads, albeit at the cost of increased radar visibility. Its advanced electronic capabilities, including radar jamming and countermeasures, combined with secure data links, make it a critical asset for contested operational environments.
The Czech Air Force currently operates a diverse fleet, including 14 JAS-39 Gripen fighter jets for airspace surveillance under NATO’s integrated defense system, UH-1Y Venom and AH-1Z Viper helicopters for aerial support and transport, and C-295M transport aircraft for logistics and humanitarian missions. Its air defense network is further reinforced by 3D MADR radars and SPYDER and RBS-70 NG anti-aircraft systems, ensuring robust protection against modern threats.
The primary bases, such as Čáslav, host ready fighter units, while Prague-Kbely specializes in strategic transport and humanitarian missions. Recent international exercises like Lion Effort and Swift Response 2024 have demonstrated the growing interoperability of the Czech Air Force with NATO partners.
The first F-35As are expected to arrive in the Czech Republic in 2029, with full operational capability planned by the early 2030s. Preparations are underway, including infrastructure upgrades at Čáslav and Náměšť bases, such as specialized hangars, flight simulators, and maintenance facilities. Pilot and technician training has already begun, with teams sent to the United States to familiarize themselves with the F-35A’s advanced technologies.
General Čepelka highlighted that integrating the F-35A will require substantial logistical adjustments, including aligning maintenance protocols and support systems. However, he expressed confidence in the Air Force's ability to meet these challenges, supported by highly skilled personnel and sustained modernization investments.
The acquisition of the F-35A represents a pivotal moment for the Czech Air Force, equipping it to address modern threats while strengthening its role within NATO. These aircraft will not only safeguard national airspace but also contribute to collective defense missions across Europe and beyond. By investing in cutting-edge technology and enhancing its capabilities, the Czech Republic reaffirms its commitment to European security and its intent to play a key role in collective defense.
Intensive training and integration efforts support the Czech Air Force's position as a modern, interoperable force ready to tackle future strategic challenges.
