“Revolutionary Combat USV Unveiled”: Cutting-Edge Unmanned Surface Vessel Design Debuts at South Korea Drone Show

The Republic of Korea (ROK) Navy is at the forefront of naval innovation, as demonstrated by the unveiling of its new combat unmanned surface vessel (USV) at the Drone Show Korea (DSK) 2025. This event marked a significant milestone for the ROK Navy, presenting the first physical model of a combat USV in a defense-related exhibition. With the integration of advanced weaponry and sensor systems, the ROK Navy’s combat USV is poised to redefine maritime warfare. The model signifies the Navy’s commitment to evolving its unmanned capabilities, reflecting an ambitious vision for the future of naval combat operations.

Unveiling the Expanded Combat USV Model

At DSK 2025, the ROK Navy showcased the expanded combat USV model, a testament to its progressive approach in naval technology. This model integrates five sophisticated weapon systems and sensors currently employed by the ROK Navy, while also hinting at future advancements. The expanded model signifies a leap from the Batch-I and Batch-II designs, embodying the Navy’s ultimate goal in USV development. Batch-I, with a platform size of about 110 tons, carries a 20mm remote-controlled weapon station (RCWS) and a 130mm guided rocket. It is equipped with electro-optical/infrared (EO/IR) systems, electro-optical tracking systems (EOTS), LiDAR, and a 360-degree imaging camera. Batch-II distinguishes itself with the addition of a suicide drone swarm launch system, a cutting-edge technology highlighted by various exhibitors at DSK 2025.

Advanced Weaponry and Sensor Integration

The expanded combat USV model is a powerhouse of advanced weaponry and sensors, featuring a 20mm RCWS, a 2.75-inch guided rocket known as “Poniard,” a 130mm guided rocket, a C-Star anti-ship missile, and a suicide drone swarm launch system. One of the most notable features is its miniaturized AESA Multi-Function Radar (MFR), which enables long-range detection. Additionally, the model incorporates a soft-kill system akin to the Rheinmetall MASS. Propelled by three waterjets, this USV is designed for agility and speed. The integration of these systems indicates the ROK Navy’s strategic focus on automated navigation, tracking, and targeting, allowing for autonomous engagement once targets are approved.

Strategic Shift Towards Unmanned Capabilities

The ROK Navy’s decision to intensify its focus on unmanned capabilities follows the recent cancellation of its aircraft carrier program. This strategic shift emphasizes the development of versatile unmanned assets, a core component of the Navy Sea GHOST concept. Over recent years, these unmanned systems have progressed from conceptual stages to design completion, culminating in the expanded combat USV model. Designed primarily for surface warfare, these USVs are comparable in tonnage to small vessels like the PKMR, but without the need for crew accommodations. This allows for greater flexibility in weapon system integration. If successfully developed, the USV’s integrated mission module will enable seamless command and control, facilitating manned-unmanned teaming (MUM-T) operations alongside 800-ton offshore patrol vessels (OPVs).

Potential Implications for Naval Warfare

The combat USV’s introduction could significantly alter the landscape of naval warfare. As the ROK Navy continues to refine these systems, the potential for replacing existing fleets, such as the PKMR, becomes more plausible. The ability to conduct operations without onboard personnel not only enhances operational efficiency but also reduces risk to human life. Furthermore, the integration of advanced systems like the AESA MFR and the suicide drone swarm launch system offers a strategic edge in modern combat scenarios. As these unmanned vessels become a staple in naval operations, their impact on international maritime strategy and defense policies will be profound.

The ROK Navy’s unveiling of the expanded combat USV model at DSK 2025 signifies a pivotal moment in naval innovation. With its advanced weaponry, sensor systems, and autonomous capabilities, the combat USV is poised to redefine naval combat. As these technologies continue to evolve, the question remains: how will global navies adapt to the growing prominence of unmanned systems in maritime warfare?
