Description
The ASM-3 is a supersonic air-to-surface missile developed as a successor to the ASM-1 and ASM-2 systems. Initial operational capability was projected for 2016, with development concluding in 2017. Mass production of the baseline model was deferred to prioritize range extension programs intended to counter long-range air defense systems.
The missile is powered by an integral rocket ramjet engine. It is designed for the engagement of maritime vessels and land-based targets. The guidance suite utilizes inertial and GPS navigation for the mid-course phase, including mid-course correction capabilities. Terminal guidance is achieved through a combination of active radar homing and passive radar guidance.
The Japan Air Self-Defense Force is the operator of the system. The primary launch platform is the F-2 fighter, and the missile is expected to be utilized by the successor to that aircraft following its retirement in the 2030s. Evaluation of the system included a 2016 live-fire experiment against the decommissioned destroyer JDS Shirane. Subsequent testing involved a jettison trial in February 2017 and a recorded test launch in August 2017. Deployment of the ASM-3A variant began in 2021. Development is also proceeding on the ASM-3 Kai, an improved version of the extended-range variant.
