Turkey and Spain in Talks for KAAN Fifth-Generation Fighter Export
Turkey’s TAI holds preliminary talks with Spain to export the KAAN stealth fighter amid Spain’s need to replace aging jets and FCAS delays.

Turkish Aerospace Industries (TAI) is currently engaged in preliminary government-to-government negotiations with Spain regarding the potential export of Turkey’s domestically developed fifth-generation stealth fighter, the KAAN. According to reporting by Turkish Minute, TAI Chief Executive Mehmet Demiroğlu confirmed the discussions during the SAHA 2026 International Defense and Air-Shows Exhibition in Istanbul.
If finalized, this agreement would mark a historic milestone in European defense procurement, representing the first time a Turkish fifth-generation fighter is exported to a NATO and European Union member state. The talks highlight a growing trend among European nations seeking sovereign control over their combat aviation assets and reducing reliance on traditional suppliers.
Spain is reportedly exploring the KAAN as a stopgap solution to replace its aging fleet of F/A-18 Hornets and AV-8B Harriers. This pivot follows Madrid’s rejection of the US-made F-35 Lightning II and ongoing developmental delays in the European Future Combat Air System (FCAS) program, which have left the Spanish Air and Space Force facing a critical capability gap.
The Catalyst for Spain’s Pivot
Rejection of the F-35 and FCAS Delays
Spain’s interest in the Turkish fighter stems from a complex mix of operational urgency, industrial ambition, and geopolitical friction. In August 2025, Madrid officially shelved plans to procure the Lockheed Martin F-35. Industry reports indicate this decision was heavily influenced by US restrictions on critical technology access and concerns over potential operational vetoes from Washington. Furthermore, diplomatic friction between Spanish Prime Minister Pedro Sánchez and US President Donald Trump has reportedly strained bilateral relations, pushing Spain to look for alternative defense partners.
Compounding the issue is Spain’s participation in the Future Combat Air System (FCAS). Co-developed with France and Germany, the next-generation fighter program has faced internal work-sharing disagreements and developmental hurdles. According to defense estimates, the FCAS is not expected to reach operational status until the mid-2040s, creating an urgent need for an interim solution.
The Hürjet Precedent
The groundwork for this potential KAAN acquisition was laid late last year. In late 2025, Spain approved a major Contracts to acquire between 30 and 45 Turkish Hürjet advanced jet trainers. Valued between €2.6 billion and €3.12 billion, the deal allows Airbus España to domestically integrate mission computers and selected Avionics. This arrangement, which designates the trainer as the SAETA II in Spain, established a successful template for industrial cooperation and technology transfer between the two nations.
Inside the KAAN Negotiations
Early Stages and Industrial Participation
The current negotiations remain in a very initial phase, involving both technical and political channels. Formal government-to-government discussions, coordinated on the Turkish side by the Presidency of Defense Industries (SSB), are expected to accelerate around 2027 as the KAAN program matures.
According to Turkish Minute, TAI Chief Executive Mehmet DemiroÄŸlu confirmed the talks, noting that Spain expressed a strategic requirement for a “superior fifth-generation fighter.”
A critical selling point for Madrid is the promise of technology transfer. TAI is reportedly offering an industrial participation model similar to the Hürjet agreement. This framework would permit Spanish defense contractors to integrate their own electronic warfare systems, mission Software, and datalinks into the KAAN, ensuring sovereign control without the centralized foreign oversight required by US platforms.
Technical Profile of the KAAN Fighter
Development and Capabilities
The KAAN is a twin-engine, single-seat, fifth-generation stealth fighter designed with low-observable shaping, internal weapons bays, and an Active Electronically Scanned Array (AESA) Radar-Systems. TAI officials have publicly highlighted its twin-engine configuration and 10-ton ammunition capacity as distinct advantages over the single-engine F-35.
The aircraft is currently in its prototype and developmental testing phase. It completed its Maiden-Flight on February 21, 2024, followed by a second test flight on May 6, 2024. Additional prototypes are scheduled for completion in 2026 and 2027.
Production and Export Goals
Domestically, the KAAN is slated to replace the Turkish Air Force’s F-16 fleet beginning in the 2030s. TAI aims to deliver 20 Block-10 aircraft between 2028 and 2030, with hundreds more projected by 2033. On the export front, Spain would become the second major international customer if the deal proceeds. In 2025, Indonesia signed a $10 billion agreement for 48 KAAN fighters, a deal that also featured extensive technology transfer and manufacturing collaboration.
Strategic Implications
AirPro News analysis
We observe that Madrid’s preliminary talks with Ankara signal a profound shift in NATO combat aviation strategy. By prioritizing national sovereignty and software control over the immediate operational maturity of established platforms like the F-35, Spain is charting a more autonomous defense posture. This approach allows European nations to maintain their domestic aerospace industries while bridging the gap to future indigenous programs like the FCAS.
For Turkey, securing a prominent Western European buyer would catapult its defense industry into the upper echelon of global arms exporters. This move threatens to fracture the long-standing transatlantic monopoly over fifth-generation fighter exports, proving that emerging defense sectors can successfully compete by offering flexible, sovereignty-focused industrial packages.

Türkiye Signs Contract for Mass Production of KAAN Stealth Fighter
Türkiye formalizes contract to produce 20 KAAN fifth-generation stealth fighters by 2030, with export deals to Indonesia and talks with Spain.

This article summarizes reporting by Anadolu Agency.
On May 6, 2026, Türkiye achieved a major milestone in its defense sector by signing the first procurement contracts for the mass production of the KAAN, its domestically developed fifth-generation stealth fighter. The agreement was formalized at the SAHA 2026 International Defense and Aerospace Exhibition in Istanbul, according to reporting by Anadolu Agency.
The contract officially transitions the KAAN from its prototype and development phase into serial production. The Turkish Air Force is scheduled to receive an initial batch of 20 Block-10 aircraft between 2028 and 2030. This procurement represents a critical step in Ankara’s long-term strategy to replace its aging F-16 fleet and establish aerospace sovereignty.
Alongside the KAAN agreement, officials also signed a serial production contract for the ANKA-3 unmanned combat aerial vehicle (UCAV). Industry research indicates the ANKA-3 is designed to operate as a “loyal wingman” alongside the KAAN, utilizing a modern Manned-Unmanned Teaming (MUM-T) concept.
Contract Details and Delivery Timelines
Formalizing the Agreement
The historic signing ceremony featured key figures in the Turkish defense industry, including Haluk Görgün, President of the Defense Industries Secretariat (SSB); Ömer Cihad Vardan, Chairman of Turkish Aerospace Industries (TAI); and Mehmet Demiroğlu, CEO of TAI.
The initial order focuses on the Block-10 variant of the KAAN. Delivery of these 20 jets to the Turkish Air Force Command is slated to begin in 2028 and conclude by the end of 2030, as outlined in the provided research data.
“Starting from 2028, we aim to deliver 20 Block-10 KAAN aircraft to the HKK by the end of 2030,” stated Haluk Görgün, Head of the Defense Industries Secretariat.
Company leadership emphasized that this initial procurement is just the beginning of a much larger production run.
“The initial sale was made for the first batch of 20 Block 10 aircraft… Over time, we expect the numbers to increase,” noted TAI CEO Mehmet DemiroÄŸlu.
Technical Specifications and Engine Development
Fifth-Generation Capabilities
Initiated in 2010 and officially contracted for development in 2016, the KAAN completed its maiden flight on February 21, 2024. The twin-engine, single-seat aircraft is designed to compete with other fifth-generation fighters by prioritizing stealth, survivability, and sensor fusion.

The aircraft is equipped with an Active Electronically Scanned Array (AESA) radar developed by Aselsan, alongside advanced electronic warfare suites and AI-assisted mission systems.
The Path to Propulsion Independence
A critical element of the KAAN program is its propulsion system. Early prototypes and the initial Block-10 production models will utilize American-made General Electric F110 engines. However, to ensure full export independence, Türkiye is developing an indigenous turbofan engine known as the TF35000.
Unveiled in May 2025, the TF35000 is being developed by TAI Engine Industries (TEI) and TRMotor. The engine is designed to produce 35,000 pounds of thrust, which will enable supercruise capabilities. Prototype production is expected to begin in 2027, with integration into the Block-30 KAAN platforms targeted for 2032.
Global Implications and Export Markets
Disrupting the Defense Market
The KAAN program is positioning Türkiye as a viable alternative for nations seeking fifth-generation fighter capabilities without the political restrictions often associated with Western defense contractors.
In July 2025, Indonesia became the first export customer for the KAAN, signing a $10 billion contract for 48 aircraft. This 10-year delivery agreement includes extensive technology transfer and the establishment of local aerospace infrastructure in Indonesia, according to industry reports.
Furthermore, as of May 2026, Spain is reportedly in preliminary government-to-government talks with Türkiye regarding a potential acquisition of the KAAN. Following Madrid’s rejection of the F-35 and delays in the European Future Combat Air System (FCAS) program, Spain is reportedly drawn to Türkiye’s offer of deep technology transfer, a model previously established when Spain purchased Turkish Hürjet trainer aircraft.
AirPro News analysis
At AirPro News, we view the transition of the KAAN from development to serial production as a watershed moment for Türkiye’s defense autonomy. The phased shift from US-made General Electric engines to the domestic TF35000 will be the ultimate test of the program’s long-term viability and export potential.
