In a significant development for Japan’s defense capabilities, a new electronic-warfare aircraft has made its maiden flight. Converted from the Kawasaki C-2 tactical cargo plane, this EC-2 aircraft represents a strategic leap forward in Japan’s efforts to enhance its electronic warfare capabilities, amid a tense regional environment.
The EC-2, which took off from Gifu Air Base on March 17, is a cornerstone of Japan’s plan to have the aircraft operational by March 2027. The Japan Air Self-Defense Force (JASDF) emphasized its commitment to advancing capabilities in the electromagnetic domain, stating: “We’ll continue working toward its introduction to improve capabilities in the electromagnetic domain, and to strengthen the cross-domain operations capabilities.” Once operational, the EC-2 is set to join the Electronic Warfare Operations Group at Iruma Air Base, located east of Tokyo.
Funding for the project remains robust, with last year’s defense budget allocating 41.4 billion yen (approximately $262 million) for the continued development of the EW aircraft. The aircraft’s conversion is notable, as it was developed from the first production C-2 transport delivered to the JASDF. The C-2’s size and capabilities, akin to an Airbus A400M, made it an ideal candidate for this transformation due to its impressive payload capacity and flight performance.
Despite its unconventional appearance, featuring a bulbous nose, dorsal humps, and lateral fairings, the EC-2 plays a critical role in disrupting enemy radar and communication systems from afar. Equipped with advanced jamming technology, electronic countermeasures, electronic support measures, and satellite communications, the EC-2 is prepared to address the threats posed by neighboring countries like China, North Korea, and Russia. The J/ALQ-5 jamming system, a domestic innovation, is among the specialized equipment onboard.
Japan’s fiscal 2026 budget underscores the importance of gaining superiority in the electromagnetic spectrum, noting, “The electromagnetic spectrum has become the frontline of offense and defense in modern combat. In light of this situation, securing superiority in the domain of electromagnetic spectrum is an urgent issue.”
The expansion of Japan’s electronic-warfare fleet from a single EC-1 aircraft to potentially four EC-2s highlights the growing emphasis on electronic attack capabilities. The exact number of EC-2s to be acquired remains under consideration, but the transition signifies a strategic shift in Japan’s defense priorities.
Kawasaki has delivered 18 C-2s to the JASDF, with one converted into an EC-2 and another into an RC-2 electronic-intelligence platform. The remaining 16 aircraft are still configured for transport. Budgets since 2024 have also included funds for additional RC-2 aircraft, reflecting ongoing efforts to bolster electronic intelligence capabilities.
Additionally, the JASDF has experimented with the American Rapid Dragon palletized weapons module on a C-2, potentially enabling long-range cruise missile launches from transport aircraft. However, decisions regarding the future acquisition of this system are still pending.
