Overview

As part of its major military shift, Japan is developing five cutting-edge weapons systems aimed at bolstering its naval capabilities and countering emerging threats in the region. These advanced systems are set to be tested and deployed by 2030.

The 5 Weapons

  1. Combat Support Multipurpose Unmanned Surface Vessel (USV)

    • Autonomous or remotely controlled vessel for reconnaissance, surveillance, and combat
    • Counters enemy ships and submarines, shares data with other USVs
    • Can submerge to evade threats, uses quiet electric propulsion and fuel cells

  2. Unmanned Amphibious Vehicle (UAV)

    • Supports Manned Assault Amphibious Vehicle (AAV) in securing enemy territory
    • Autonomous or remotely controlled, uses AI for decision-making
    • Communicates with other UAVs and AAVs, compact chassis for reef maneuverability

  3. Upgraded Type 12 Torpedo with Anti-Torpedo Capabilities

    • Converts Type 12 torpedo into an anti-torpedo torpedo (ATT)
    • Physically destroys high-speed enemy torpedoes
    • Integrates with upgraded destroyer sonar for early threat detection

  4. Glide Phase Interceptor (GPI) and Detection Systems

    • Counters hypersonic weapons like Hypersonic Glide Vehicles and Anti-Ship Ballistic Missiles
    • Multiband radar detects small, fast, maneuverable targets; Combat Management System enables autonomous sensor/weapon coordination

  5. New Ship-to-Air Missile (NSAM)

    • Improved Ship-to-Air Missile (SAM) variant designed to destroy hypersonic weapons
    • Enhanced seeker, side thrusters, and Fire Control System for better targeting
    • Utilizes data from multiband radar and Combat Management System

These advanced weapons demonstrate Japan’s commitment to adapting its military to the changing security landscape in East Asia. As these systems come online, they will significantly enhance Japan’s ability to defend its interests and counter potential threats from regional adversaries.
