Saudi-Turkey KAAN Fighter Talks Rattle Washington as F-35 Deal Hangs in Balance

(DEFENCE SECURITY ASIA) — Saudi Arabia’s exploratory engagement with Turkey over participation in the KAAN next-generation fighter programme has injected fresh volatility into an already sensitive U.S.–Gulf defence relationship, with current and former American officials warning that Riyadh’s parallel negotiations risk diluting Washington’s leverage at a moment when F-35 Lightning II sales are under delicate negotiation.

“The message to the Saudis has been, ‘What need do you feel is not being met by the US, that you need to go to Turkey for the KAAN?’” a U.S. official familiar with the matter stated anonymously to a regional publication, underscoring an emerging perception within the Trump administration that Saudi diversification is not merely transactional but strategically symbolic.

The Trump administration, which framed the November 2025 F-35 approval as part of a “historic strategic defense agreement,” now confronts a reality in which Riyadh appears determined to hedge its bets between Lockheed Martin’s fifth-generation ecosystem and Turkish Aerospace Industries’ rapidly advancing KAAN platform.

 

Reports indicate that Saudi Arabia is evaluating procurement of up to 100 KAAN aircraft, a figure that—if pursued—would represent one of the most consequential co-development alignments in the global fighter market and potentially reshape the balance between American defence primacy and emerging middle-power aerospace ambitions.

The Saudi manoeuvre unfolds as negotiations continue over an initial batch of up to 48 F-35 jets valued at billions of dollars, with Riyadh pressing for enhanced maintenance autonomy, spare parts control, and limited co-production rights consistent with Crown Prince Mohammed bin Salman’s Vision 2030 localisation agenda.

This dual-track strategy is widely interpreted as calibrated leverage rather than ideological realignment, positioning Saudi Arabia to extract technology transfers and industrial offsets from Washington while simultaneously signalling to Ankara that the Gulf remains fertile ground for Turkish fifth-generation aspirations.

“Riyadh is toying with Turkey as it pursues advanced F-35 warplanes and forges new partnerships to check Israel and UAE,” according to analysis cited by Middle East Eye, framing the Saudi approach as a calculated diversification tactic rather than a wholesale pivot away from U.S. security architecture.

A defence analyst amplifies this perception, stating, “Saudi Arabia’s reported interest in Turkey’s next-generation Kaan fighter jet is raising concerns in Washington. The Trump administration wants to remain the kingdom’s primary arms supplier,” capturing the transactional anxiety reverberating through U.S. policy circles.

The strategic implications extend beyond aircraft procurement, reflecting a broader Gulf recalibration in which advanced fighter acquisitions are embedded within industrial policy, geopolitical hedging, and the contest for influence between established Western suppliers and assertive regional defence manufacturers.

KAAN’s Strategic Ambition and the Turkish Fifth-Generation Calculus

The KAAN programme, formerly known as TF-X, represents Turkey’s bid to re-enter the fifth-generation fighter domain after its 2019 expulsion from the F-35 consortium, positioning Ankara as both a competitor to and a potential complement of Western aerospace architectures.

Initiated in 2010 under Turkish Aerospace Industries, the twin-engine platform achieved its maiden flight in February 2024, marking a symbolic inflection point in Ankara’s long-term ambition to indigenise high-end air combat capabilities and reduce exposure to export restrictions imposed by external partners.

Powered initially by General Electric F110 engines, KAAN’s development roadmap envisages supercruise performance, advanced sensor fusion, and low observability features, with Turkish officials consistently presenting the aircraft as a sovereign alternative to platforms constrained by stringent U.S. export regimes.

From a capability perspective, KAAN is designed to undertake air superiority, ground attack, and electronic warfare missions, seeking parity in multi-role flexibility with Western counterparts while promising prospective partners greater customisation and intellectual property participation.

Turkey’s exclusion from the F-35 programme following its acquisition of the Russian S-400 air defence system has infused KAAN with geopolitical significance, transforming it from an industrial initiative into a strategic counterweight within NATO’s internal dynamics.

The potential re-entry of Turkey into F-35 discussions, hinted at by President Trump, introduces a layer of competitive complexity, as Ankara simultaneously courts Saudi participation in KAAN while navigating an uncertain pathway toward reconciliation with Washington.

Saudi financial or industrial participation in KAAN would materially accelerate the programme’s maturation, potentially providing development capital, test infrastructure, and export credibility that could reshape its trajectory from prototype to operational platform by the early 2030s.

Turkey’s defence exports, reported at $5.5 billion in 2025, underscore the momentum behind Ankara’s broader military-industrial expansion, with KAAN positioned as the flagship platform capable of elevating Turkey into the elite tier of fighter-producing nations.

The programme’s appeal to Saudi Arabia lies not only in aircraft performance metrics but in its openness to co-development structures, aligning with Riyadh’s demand for deeper technology transfer frameworks than those traditionally associated with U.S. fifth-generation sales.

F-35 Negotiations, Technology Security, and American Leverage

Saudi Arabia’s pursuit of the F-35 Lightning II, operational since 2016 and delivered in over 1,000 units globally, remains central to its ambition to secure immediate fifth-generation capability within the Royal Saudi Air Force.

The November 2025 approval by President Trump signalled a political breakthrough after years of hesitation driven by concerns over technology security, human rights issues, and the preservation of Israel’s qualitative military edge under U.S. law.

The proposed initial tranche of up to 48 aircraft—potentially worth tens of billions of U.S. dollars, equivalent to well over RM200 billion depending on configuration and sustainment packages—represents a high-stakes commercial and strategic commitment.

Yet negotiations reportedly remain active over maintenance sovereignty, spare parts control, and limited co-production rights, with Saudi Arabia seeking terms that extend beyond traditional foreign military sales frameworks into more integrated industrial participation.

A Pentagon intelligence report warning of potential Chinese espionage targeting F-35 technology in Saudi Arabia adds another layer of complexity, reflecting Washington’s apprehension regarding Beijing’s expanding security footprint in the Gulf.

U.S. officials view the KAAN discussions as a potential dilution of American export dominance, particularly under an administration committed to positioning the United States as the “sole provider” of advanced weaponry to key allies.

The friction intensified after Trump’s F-35 announcement, with officials expressing concern that Saudi investment in KAAN could erode U.S. negotiating leverage and weaken the political signalling value of American exclusivity.

The precedent of the United Arab Emirates suspending F-35 talks in 2021 over “sovereign operational restrictions” illustrates that Gulf states have previously used diversification to renegotiate terms, reinforcing the perception that Riyadh’s approach is neither impulsive nor unprecedented.

In economic terms, Saudi Arabia’s annual defence budget exceeding $75 billion—approximately RM350 billion—constitutes one of the world’s most lucrative procurement environments, magnifying the competitive stakes between Lockheed Martin and Turkish Aerospace Industries.

Vision 2030, Localisation Imperatives, and Industrial Sovereignty

Saudi Arabia’s Vision 2030 framework situates fighter procurement within a broader economic transformation agenda aimed at reducing hydrocarbon dependency and cultivating high-technology industrial ecosystems.

Crown Prince Mohammed bin Salman’s blueprint emphasises joint ventures, technology transfer, and co-manufacturing agreements designed to generate 40,000 defence-sector jobs by 2030, embedding procurement decisions within domestic employment and skills strategies.

Saudi delegations have reportedly visited Turkish Aerospace Industries facilities multiple times since mid-2024, signalling sustained institutional engagement rather than exploratory diplomacy.

Discussions encompassing up to 100 KAAN units imply not only acquisition but potential investment stakes in the programme’s development phases, positioning Riyadh as a partner rather than a mere customer.

Such participation would grant Saudi Arabia intellectual property exposure and industrial learning curves that align more closely with Vision 2030 than traditional off-the-shelf purchases.

At the same time, F-35 negotiations reportedly include demands for maintenance autonomy and partial industrial integration, suggesting Riyadh is applying consistent localisation criteria across suppliers.

The improving Saudi–Turkish relationship since 2021, marked by President Recep Tayyip Erdogan’s early-2026 visit and the signing of a military framework agreement, provides the diplomatic scaffolding for expanded aerospace collaboration.

Potential cooperation extending to Baykar Akinci drones and Aselsan air defence systems indicates that KAAN discussions are embedded within a wider defence industrial dialogue.

The localisation imperative therefore functions as both economic policy and geopolitical hedge, enabling Saudi Arabia to diversify supplier risk while signalling that advanced technology access is non-negotiable.

Regional Reactions and the Israel–UAE–Iran Security Equation

Israel has expressed reservations about F-35 sales to Saudi Arabia or Turkey, citing concerns over the erosion of its qualitative military edge, a principle embedded within U.S. statutory frameworks.

The United Arab Emirates, itself navigating a paused F-35 deal and expanding defence ties with Turkey, monitors the Saudi calculus with an awareness that Gulf procurement decisions often produce cascading strategic effects.

Iran, observing the potential introduction of additional fifth-generation platforms into the Gulf theatre, is likely to interpret these developments as escalatory, reinforcing its emphasis on asymmetric capabilities and missile investments.

A geopolitical observer frames the central question pointedly: “With Saudi Arabia previously keen on acquiring F-35 fighter jets from the United States, what has steered Riyadh toward Turkish technology?” highlighting frustrations over congressional hurdles and prioritisation of Israel.

The Jerusalem Post similarly notes that “Saudi Arabia also wants the F-35, and the Trump administration appears keen on a deal. However, there are concerns in Israel about Turkey or Saudi Arabia acquiring the warplane,” capturing the layered sensitivities embedded within regional airpower balances.

Turkey’s NATO membership complicates U.S. efforts to contain Russian and Chinese influence in defence markets, particularly given Ankara’s previous S-400 acquisition and the lingering CAATSA sanction risks.

Saudi acquisition of both F-35 and KAAN platforms remains technically feasible, potentially yielding a hybrid fleet combining immediate stealth capability with long-term co-development benefits.

Such an outcome would represent a multi-source airpower architecture unprecedented in the Gulf, reshaping interoperability, training pipelines, and supply chain dependencies.

The broader implication is the emergence of a multipolar arms market in which technological merit intersects with industrial sovereignty, alliance management, and political signalling.

A Multipolar Arms Market and the Future of Gulf Airpower

The Saudi–Turkey KAAN discussions illustrate that modern defence procurement is inseparable from geopolitical positioning, particularly in regions where alliance structures remain fluid and security guarantees are periodically reassessed.

Washington’s ambition to put “American exports first” collides with Riyadh’s evident determination to maximise industrial and strategic autonomy, producing friction that transcends the technical attributes of any single aircraft.

The KAAN’s prototype status, reliance on foreign engines in early blocks, and integration challenges coexist with the F-35’s mature supply chains and operational pedigree, creating a layered comparison rather than a binary choice.

Economic incentives remain formidable, as Turkish co-production could stimulate its domestic aerospace sector while offering Saudi Arabia pathways toward industrial diversification measured in tens of billions of dollars and substantial Ringgit equivalents.

Yet uncertainties persist regarding U.S. export conditions, potential espionage concerns, and the durability of Turkish–American reconciliation efforts, leaving final outcomes contingent on high-level political negotiations.

The Gulf security architecture, already recalibrating amid fluctuating U.S. engagement levels, may evolve toward greater supplier diversity as states hedge against policy volatility in Washington.

Whether Saudi Arabia ultimately acquires both platforms or secures improved F-35 terms through calibrated pressure, the episode signals a structural shift in bargaining dynamics between suppliers and affluent defence consumers.

In this evolving landscape, advanced fighter procurement functions not merely as a military decision but as a strategic instrument through which states negotiate influence, autonomy, and industrial transformation.

The Saudi–Turkey KAAN talks therefore resonate far beyond Ankara and Riyadh, reflecting a defence market in which technological ambition, geopolitical leverage, and economic statecraft converge to redefine the hierarchy of global airpower.
