Japan is significantly strengthening its underwater defense capabilities by adding unmanned aerial vehicles (UUVs) capable of launching heavy torpedoes into the fleet of the Japan Maritime Self-Defense Force (JMSDF).
Information about this program was announced by the JMSDF on social networks, along with images of at least six black UUVs manufactured domestically at an undisclosed location.
Although the detailed configuration has not been disclosed, sources say the new UUV uses a 533 mm diameter torpedo launcher, equivalent to a modern heavy torpedo standard.
A noteworthy point is that this system can be deployed and recovered directly from submarines, allowing flexible integration into combat, reconnaissance and maritime security missions.
Thanks to this design, UUVs can operate secretly, reduce personnel risks and increase the effectiveness of controlling strategic sea areas.
According to JMSDF, the commissioning of UUVs demonstrates efforts to modernize the navy and expand the role of unmanned platforms.
The JMSDF is gradually strengthening its defense capabilities, including unmanned vehicles, to enhance deterrence and response capabilities," the agency affirmed.
Japan's UUV development program started in 2019, implemented by the Japanese Ministry of Defense in coordination with the Agency for Procurement, Technology and Logistics (ATLA). Two main designs have been studied in parallel including:
- Type 1 developed by Ishikawajima-Harima Heavy Industries (IHI).
- Type 2 led by Mitsubishi Heavy Industries.
The first orders were placed in 2021, marking a shift from research to practical deployment in the navy.
Japan's accelerated development of torpedo-launching UUVs reflects the global trend in applying unmanned technology to naval operations, while strengthening surveillance, defense and protection capabilities at sea in the context of an increasingly complex regional security environment.
