Japan tests new EC-2 electronic warfare aircraft

The Japan Air Self-Defense Force confirmed it supported the first flight of a new stand-off electronic warfare aircraft, known as the EC-2, developed in cooperation with the Acquisition, Technology and Logistics Agency.

The development comes as Japan moves to strengthen its ability to operate in the electromagnetic domain and support air operations without entering contested air defense zones.

In a statement, the Japan Air Self-Defense Force said it had “supported the first flight of a stand-off electronic warfare aircraft,” describing the platform as an aircraft designed to assist operations through effective electronic jamming.

“Through effective electronic jamming, [the aircraft] supports the execution of air operations,” the service stated.

According to the announcement, the EC-2 is intended to interfere with adversary systems across the electromagnetic spectrum while operating at a distance, reducing exposure to surface-to-air threats.

The aircraft is derived from Japan’s domestically developed Kawasaki C-2 twin-jet transport platform. Development of the EC-2 began in 2021 as part of a broader effort to expand Japan’s electronic warfare capabilities.

The platform is designed to conduct stand-off jamming missions, targeting radar, communications, and other electronic systems used by opposing forces. By operating outside the range of enemy air defenses, the aircraft can disrupt command and control networks while supporting friendly air operations.

In practical terms, stand-off electronic warfare aircraft act as airborne jamming platforms. They emit signals that interfere with or degrade enemy sensors and communications, reducing the effectiveness of air defense systems and complicating coordination between units.

This allows allied aircraft to operate with reduced risk, particularly in environments where integrated air defense systems rely heavily on radar tracking and networked communications.

The EC-2 is expected to replace the Japan Air Self-Defense Force’s earlier EC-1 electronic warfare aircraft. The EC-1, which was converted from a C-1 transport airframe, had been operated for years by the Electronic Warfare Operations Group at Iruma Air Base in Saitama Prefecture before its retirement.

The introduction of the EC-2 reflects a shift toward more advanced and scalable electronic warfare platforms, built on modern airframes with greater range and payload capacity.

According to the service, the aircraft is part of ongoing efforts to strengthen cross-domain operational capability, particularly in the electromagnetic spectrum, which is increasingly viewed as a key area of modern military operations.

Electronic warfare has become a central component of contemporary conflict, as militaries rely on sensors, communications, and data links to coordinate operations across air, land, sea, and space domains.
