Japan’s Acquisition, Technology & Logistics Agency (ATLA) has revealed the first details of a new long-range anti-ship missile program, designed to strengthen the country’s remote island defense capabilities amid an increasingly challenging strategic environment in the Indo-Pacific.
According to ATLA, the program focuses on developing a next-generation modular platform that combines advanced propulsion, guidance technologies, and high-speed data-link capabilities within a compact, low-observable airframe.

Initial prototype will be tested in 2025
The first prototype, currently under development for fiscal year 2025, will use an XKJ301-1 turbojet engine. This initial variant will serve as a testbed for propulsion, guidance, and seeker-integration technologies.
The missile’s structure features modular internal bays designed to accommodate various payloads and mission-specific control systems. Official documents describe the design as a decisive step toward validating an airframe based on an “open architecture,” allowing rapid incorporation of upgrades and future sensors.
Modular design and multifunction variants
An official diagram released by ATLA illustrates the modular concept behind the new missile family. On the left, several interchangeable modules are shown, including:
- Dual seeker
- Infrared seeker
- Jammer and decoy unit
- EO/IR sensors
- High-power warhead
In the center, the project presents a common multi-role structure, while the right side shows combinations that result in different operational variants, such as anti-ship models, reconnaissance missiles, decoys, and strike versions.
New airframes and advanced sensors by 2027
A second test phase, scheduled for 2027, will include two additional airframes — designated A and B — which will evaluate electro-optical and infrared seekers, as well as high-speed data-link systems. The prototypes will also test new control surfaces and composite materials developed to further reduce radar signature.
Japanese experts say the program builds on knowledge gained from previous efforts, particularly the modernization of the Type 12 missile. Although ATLA has not disclosed the estimated range, the airframe size and turbojet propulsion indicate that the missile may significantly exceed the capabilities of current land-launched systems.
Part of Japan’s long-range defense strategy
Development of the missile comes amid a broader transformation of Japan’s defense capabilities, including investments in long-range precision weapons, extended-range cruise missiles, and hypersonic glide vehicles to strengthen remote and preventive defense of its territory.
The new anti-ship missile is expected to integrate into a future distributed strike network, operating alongside systems launched from aircraft, ships, and land-based platforms.
