In Iran war debut, South Korea’s cut-price Patriot outshines US interceptors

South Korea built the Cheongung-II to stop North Korean missiles. Now the system is stopping Iranian ones – and in doing so, has turned Seoul into one of the most sought-after defence suppliers on the planet. The medium-range surface-to-air missile system, also known as the KM-SAM Block II, has scored a reported interception rate of 96 per cent against Iranian missiles fired at the United Arab Emirates. It was a combat debut that rivalled, and in some cases exceeded, the performance of the US Patriot anti-missile system, analysts said. The difference is price: the Korean system costs roughly one-third as much. That combination of battlefield credibility and competitive pricing has set off a scramble. When a UAE Air Force C-17 strategic transport touched down at Daegu Airport earlier this month, its hold was being loaded with South Korean interceptor missiles headed back to the Gulf under conditions of some urgency. The Cheongung-II had passed the only test that truly mattered and Abu Dhabi wanted more. “As security concerns over Iran’s missile and drone attacks rise across the Middle East, few suppliers other than South Korea can deliver air defence systems on short notice,” said Professor Jang Won-joon of Jeonbuk National University’s Advanced Defence Industry Studies Department. “Following its strong battlefield performance, the interceptor system has drawn significant international attention, improving the outlook for South Korea’s defence exports.” A Cheongung-II battery is built around simplicity and speed. Four launcher vehicles, each fitted with eight launch tubes, operate alongside a multifunction radar and an engagement control station. Few suppliers other than South Korea can deliver air defence systems on short notice Jang Won-joon, professor at Jeonbuk National University The system has a maximum range of around 40km (25 miles) and can engage targets at altitudes below 15km (nine miles) – precisely where Iranian ballistic missiles and drones have been operating. Often described as a “missile that shoots down missiles”, it was designed to slot into a layered national air defence network and integrates readily with US and Nato platforms, allowing operators to deploy it almost immediately on delivery. The UAE had already taken delivery before the current conflict intensified. Saudi Arabia and Iraq had signed contracts for the system too. The UAE alone ordered 10 batteries, of which two arrived under the agreed schedule. But after the intercept figures emerged, Abu Dhabi requested expedited delivery of its remaining batteries under a 2022 contract, and separately sought 30 additional interceptor missiles – the consignment that prompted this month’s airlift from Daegu. “Due to the urgency of defending against ongoing Iranian missile threats, 30 interceptor missiles were airlifted to the UAE earlier this month,” Jang said. “The UAE is also urging South Korea to bring forward delivery of the remaining batteries.” Seoul has signalled that it cannot easily accelerate delivery, as it is constrained by prior production commitments. Plus the missiles dispatched to the UAE were originally allocated to South Korea’s own military. “This could temporarily affect readiness against North Korea’s missile threats,” said Lee Il-woo, a senior researcher at the Korea Defence Network. Oil for missiles Following a recent visit to the Gulf, South Korea’s presidential chief of staff, Kang Hoon-sik, announced that the UAE had pledged to supply Seoul with crude oil “with top priority” – a commitment widely interpreted as a reciprocal gesture for the speed and flexibility of South Korea’s missile response. “The UAE made clear that no country would receive crude oil ahead of South Korea, designating us as its top priority,” Kang said. South Korea is set to receive a total of 24 million barrels – including an earlier tranche of 6 million – enough to cover more than nine days of domestic demand. Abdulkhaleq Abdulla, a political scientist and informal adviser to the UAE president, reinforced the message publicly, posting on social media that the rapid delivery of interceptors reflected the depth of bilateral ties. Lee suggested the energy pledge was more than diplomatic courtesy. Seoul accepted the transfer knowing it would leave a temporary gap in its own defences – a risk that the oil commitment helped offset politically, if not militarily. For Hanwha Aerospace, the Cheongung-II’s primary manufacturer, the combat results have opened conversations that sales brochures never could. “Following recent developments in the region, we have observed increased interest from countries in the Middle East beyond our existing customers, particularly as the importance of integrated air and missile defence has become more evident,” said a company official, requesting anonymity. That interest extends to the full suite of South Korean air defence capabilities. Seoul is positioning itself not merely as a missile supplier but as a provider of an entire security architecture. At the low end, the K30 Biho self-propelled system uses 30mm guns to neutralise drones and low-flying aircraft. At the high end, the domestically developed L-SAM interceptor – designed to engage threats at extreme altitudes and widely seen as South Korea’s answer to the US THAAD anti-missile system – is scheduled to enter service next year, with mass production expected to begin later. The UAE and Saudi Arabia have reportedly expressed interest in the L-SAM even before it reaches full-scale production. “The success of Cheongung-II has increased interest among international buyers in Korea’s broader air defence architecture, including the Biho system and the L-SAM interceptors,” Jang said. Inquiries have also been made into emerging technologies. Directed-energy systems, particularly laser-based solutions for countering unmanned aerial threats, are drawing growing attention as buyers seek to future-proof their defences against the kind of cheap drone saturation tactics that have defined recent conflicts. A decade in the making None of this happened by accident. Development of the Cheongung-II began in 2012 under South Korea’s Agency for Defence Development, with Hanwha Aerospace, Hanwha Systems and LIG Nex1 as the principal contractors. The programme was conceived to replace the ageing US-made Hawk surface-to-air missile system operated by the South Korean Air Force and to give Seoul an indigenous mid-range interceptor capability calibrated specifically to the North Korean threat. After roughly five years of development, the system was declared combat-ready in 2017, entered mass production in 2018 and was deployed with South Korean forces in 2020 – placing the country in the small group of nations capable of independently developing and producing a mid-range surface-to-air missile. South Korea has recorded around US$55 billion in defence sales over the past four years and currently ranks 10th globally in arms exports – a figure built not only on Cheongung-II but on a portfolio that spans the K2 Black Panther main battle tank and K9 Thunder self-propelled howitzer sold to Poland and FA-50 light combat aircraft delivered to Malaysia, the Philippines and Poland. A report published in December by the International Institute for Strategic Studies identified the structural advantages driving that growth: Delivery timelines are often tied directly to contract signing rather than years-long backlogs. Flexible maintenance and technology-transfer arrangements, including joint-venture provisions in recipient countries. Pricing that undercuts established US and European suppliers. And seamless interoperability with American and Nato platforms that allows operators to integrate Korean equipment into existing networks without costly adaptation. “For South Korea, the Cheongung-II deal represents a milestone in its effort to become one of the world’s leading defence exporters”, Dr Kristian Alexander, a senior fellow and lead researcher at the Rabdan Security and Defence Institute in Abu Dhabi, wrote in the Korea Times. “Over the past decade, Korean defence companies have steadily expanded their presence in global markets, offering high-performance systems at competitive cost while maintaining strong production capacity.” Seoul has set a formal target to enter the top four global arms exporters by 2030, backed by sustained investment in next-generation weapons, unmanned systems and AI-driven technologies. After this month’s flight from Daegu, it looks considerably more attainable.
