The UAE Tests the South Korean KF-21 Fighter After Four Years of Freezing the U.S. F-35 Deal — $15 Billion at Stake

In the summer of 2025, UAE Deputy Defense Minister Ibrahim Nasser Mohammed Al Alawi took a seat in the back of a prototype of the South Korean KF-21 Boramae fighter and took off on a "symbolic friendship" flight over the Sacheon Air Base in South Korea. This was not just a diplomatic gesture that reporters applaud. It was a message precisely directed at Washington, which has kept the UAE's F-35 deal hanging in limbo since 2021.

Months after that flight, during South Korean President Yoon Suk-yeol's visit to Abu Dhabi, the real offer came: a comprehensive partnership in the production chain that includes joint development, local assembly, and joint export rights for future variants of the KF-21. According to Bloomberg reports, the value of this partnership in the long term could exceed $15 billion in contracts for Korean companies. In April 2025, the two parties signed a letter of intent for comprehensive cooperation, and on January 28, 2026, high-level meetings took place to embody what had begun symbolically.

Four Years of American Waiting

Practically, the UAE's situation with the F-35 reveals a striking paradox: Abu Dhabi paid the price for normalization with Israel through the Abraham Accords, expecting the stealth fighter to be the prize. But Washington imposed impossible conditions centered around removing Huawei networks from the UAE's telecommunications infrastructure and tightening technological relations with China. The UAE did not accept this strategic price, and the deal was frozen.

Any military personnel who served in the region knows that this freeze is not just a bureaucratic obstacle. It reflects the limits of UAE's strategic autonomy: Abu Dhabi wants to buy the best Western weapons, but it refuses to accept the accompanying political conditions. Here, the KF-21 becomes both a pressure card and an alternative option at the same time.

What Does the Korean Fighter Actually Offer?

The KF-21 Boramae is a 4.5 generation fighter that relies on semi-stealth technology in its first and second variants. Its initial versions carry partially external weapons, and targeting and processing do not yet reach the level of the F-35. The planned third variant will feature a shift to full stealth with an internal weapons architecture, but it is still in the development stage.

• Engine: General Electric F414-GE-400K with 22,000 pounds of thrust (twin)
• Maximum Speed: 2,200 km/h (Mach 1.81)
• Combat Range: Approximately 2,900 km
• Radar: Locally made AESA radar in the development stage
• Limitations: Integrated sensing and electronic warfare do not yet reach the level of the F-35

Militarily, the KF-21 in its first variant operates at a different level than the F-35. But the UAE is not just buying an aircraft — it is purchasing a production line, technology transfer, and export rights. This is the fundamental difference between this potential deal and any deal that has occurred in the region before.

The Capability Triangle — And Why Numbers Alone Are Not Enough

In my view, the question that no one is asking is: Will this aircraft be used to its full potential? The UAE has a relatively professional air force compared to its neighbors, but the gap between owning the aircraft and operating it at a level that justifies a $15 billion investment remains wide. The "capability triangle" pattern that I have often observed in the region — buying the best weapons while neglecting training and infrastructure — may repeat itself here.

South Korea aspires to a genuine industrial partnership; the UAE wants political leverage, diversification of arms sources, and gradual independence from Washington's constraints. The two directions meet in the letter of intent, but they do not necessarily converge in the operational room.

A Pressure Card or a Real Option?

This story partially reminds me of Turkey's game with the S-400. When Ankara imported the Russian defense system, it was not primarily looking for air defense capability; it was seeking a pressure card against Washington and membership in a club that sets its own rules. Today, the UAE is playing a similar game with more diplomatic tools.

If a Trump administration returns and eases the conditions for the UAE's F-35 — a scenario not unlikely in the context of Trump's trade deals — UAE enthusiasm for Seoul may wane. But if the stalemate continues, the KF-21 will shift from a pressure card to a genuine strategic investment.

The real paradox here is that the UAE — which fundamentally protects its existential military security through its relationship with Washington — is forced to use alternative deals to extract better terms from the ally itself. This tension between reliance on the protector and the ambition for independence is not resolved by either the KF-21 or the F-35. It is structural.
