This article examines the strategic context, technical specifics, industrial implications, and broader regional impact of South Korea’s AEW&C II procurement decision, providing a comprehensive analysis of what this means for the nation’s defense posture and the evolving security landscape in Northeast Asia.

Strategic Context and the Regional Security Environment

The Korean Peninsula has long been a focal point of military tension, with North Korea’s missile and drone advancements presenting persistent challenges to South Korean and allied defense planners. Since 2011, North Korea’s missile launches have steadily increased, with notable spikes in 2016 and 2017. The threat landscape has evolved beyond traditional ballistic missiles to encompass submarine-launched platforms, railway-mobile systems, and fast-developing drone capabilities.

North Korea’s drone program, in particular, has benefited from material and training support from Russia, as well as operational experience gained by North Korean troops reportedly fighting alongside Russian forces in Ukraine. A notable incident in December 2022 saw five North Korean drones crossing the Demilitarized Zone (DMZ), with one reaching Seoul and potentially surveilling sensitive government sites. South Korea’s military response failed to neutralize the drones, exposing vulnerabilities in its counter-drone defenses.

The regional context is further complicated by China’s military modernization and assertiveness in the South China Sea and around Taiwan. The likelihood of Chinese intervention in a Korean conflict is assessed to depend on North Korea’s ability to maintain territorial control, with broader implications for South Korea’s need for independent and resilient surveillance capabilities. These developments have prompted South Korea to prioritize investments in advanced AEW&C systems capable of operating in contested electromagnetic environments and interoperating with allied forces.

South Korea’s Current AEW&C Capabilities and Operational Challenges

South Korea’s existing AEW&C fleet consists of four Boeing E-7A Wedgetail aircraft, locally designated as E-737, acquired under the Peace Eye program. These aircraft were delivered by 2012 but have faced persistent operational issues. Reports indicate that since 2015, the E-737 fleet has struggled to meet targeted availability rates, with frequent mission system failures affecting readiness.

The E-737’s Northrop Grumman Multi-role Electronically Scanned Array radar, while advanced, is maintenance-intensive and has proven susceptible to technical issues. The resulting low serviceability rates have left gaps in South Korea’s airborne radar coverage, potentially exposing the nation to undetected missile or drone incursions.

Given the limitations of ground-based radar in South Korea’s mountainous terrain and the curvature of the earth, airborne platforms are essential for comprehensive surveillance and early warning. Recognizing that simply acquiring more E-7s would not address underlying reliability issues, the government opted for a competitive procurement process to explore more advanced and cost-effective options.

The AEW&C II Procurement Process

Initiated in 2020, the AEW&C II program was structured as an open competition. Three main contenders emerged: Boeing (offering additional E-7s), Saab (with the GlobalEye based on the Bombardier Global 6500), and L3Harris (partnering with Israel Aerospace Industries’ Elta Systems and Korean Air for a Global 6500-based “Phoenix” platform).

The evaluation criteria included technical performance, operational suitability, domestic industrial participation, acquisition and lifecycle costs, and contract terms. While technical performance was deemed comparable between L3Harris and Saab, L3Harris scored higher in operational suitability and domestic industry involvement, whereas Saab led on price and acquisition terms.

On September 30, 2024, DAPA announced L3Harris as the winner. The Contracts is valued at 3.0975 trillion won (approximately $2.2–2.8 billion, depending on exchange rates and accounting). Korean Air will play a crucial role in modifying and maintaining the aircraft, ensuring technology transfer and domestic capability development.
