KAI and Hanwha Systems Propose Advanced EW/SOJ Aircraft for South Korea
Overview of the Block-I Electronic Warfare Project
In a competitive landscape for South Korea’s Block-I electronic warfare/stand-off jammer (EW/SOJ) aircraft initiative, Korea Aerospace Industries (KAI) has presented a compelling proposal utilizing the Bombardier Global 6500 airframe. This project, officially dubbed the ‘Block-I Electronic Warfare System Development Project,’ is aimed at equipping the Republic of Korea Air Force (RoKAF) with advanced capabilities akin to those found in the U.S. Air Force’s EA-37B ‘Compass Call.’
Program Objectives and Specifications
The Block-I program intends to deliver a robust EW/SOJ platform capable of:
- Disrupting enemy air-defense systems and communications networks.
- Providing strategic advantages during crises.
The Defense Acquisition Program Administration (DAPA) is currently assessing various proposals, indicating a competitive environment among defense contractors.
Competitive Landscape
KAI is collaborating with Hanwha Systems to enhance their proposal, while a rival consortium, including Korean Air and LIG Nex1, has put forward an alternative platform based on the Gulfstream G550. This competition underscores the significance of the project in strengthening South Korea’s electronic warfare capabilities.
Key Developments and Investment
The preliminary design by KAI was revealed during an exhibition at the aT Center in Seoul on September 17. This event was facilitated by the Information and Electronic Research Society of the Korean Institute of Electromagnetic Engineering and Science.
DAPA finalized the development master plan for the Block-I aircraft in April 2025, with significant financial backing anticipated. The project is set to receive an investment of approximately KRW 1.7775 trillion (equivalent to USD 1.2 billion) by 2034.
Expectations from Winning Bidders
The selected contractors will be tasked with delivering four operational aircraft to RoKAF. These platforms will be expected to have the capability to:
- Neutralize enemy air-defense systems.
- Interrupt wireless command and communication networks during hostilities.
As South Korea advances in its military modernization efforts, this initiative is critical for enhancing its deterrence and operational effectiveness in the region.
