Japan is accelerating the development of an intelligence and electronic warfare (EW) version based on its maritime patrol and anti-submarine warfare aircraft, the Kawasaki P-1.
A document released by Japan’s Ministry of Defense states that, in order to cope with an increasingly complex electronic warfare environment, an electronic warfare aircraft based on the P-1 will be developed to strengthen the electromagnetic dominance capabilities needed for inter-domain operations, incorporating the electronic intelligence gathering capabilities possessed by the multi-purpose aircraft that is scheduled for retirement in the 2030s.
To expedite the development of the EW variant of the Kawasaki P-1, the Ministry of Defense has requested a budget of 41.4 billion yen (approximately $287 million) for fiscal 2025. The entire project, which includes prototype construction and extensive testing, has an estimated cost of 82.4 billion yen (more than $572 million). The prototype is expected to be ready between 2024 and 2031, with performance testing extending to 2033.

According to Naval News site, the new electronic intelligence aircraft will be the successor to the JMSDF’s (Japan Maritime Self-Defense Forces) five EP-3 Orions, which are operated on signals intelligence (SIGINT), electronic intelligence (ELINT) and communications intelligence (COMINT) missions.
Since the Kawasaki P-1 was designed to replace the aging P-3C Orion in maritime patrol missions, it stands to reason that its electronic warfare variant is intended to replace the EP-3s.
