Unmanned Vessels Cutting Through the Seas: Where Do We Stand?
Since the early 1900s, unmanned transportation has frequently appeared in science fiction films. While self-operating or remotely controlled mobility has long been a staple element in futuristic movies, its real-world implementation has only begun relatively recently.
Global mobility companies are developing autonomous navigation and operation technologies across all modes of transportation, including automobiles, ships, and aircraft. While they all share the use of perception, judgment, and control technologies, the varying dynamics and operating environments create different levels of technical challenges.
Autonomous vessels have an advantage in control compared to cars and aircraft due to their slower speed. However, external factors such as ocean currents, waves, and wind make control particularly challenging.
Nevertheless, research and technological development are in full swing to enable autonomous navigation and unmanned operations across commercial vessels, leisure boats, and naval ships.
Unmanned Vessels: From Large Commercial Ships to Leisure Boats
Unlike cars and aircraft that can operate with minimal crew, commercial vessels requiring 20-30 crew members need a broader range of automated navigation technologies.
Avikus, HD Hyundai's specialized autonomous navigation technology subsidiary, developed the first navigation assistance system for large commercial vessels in April 2020. This system was developed based on HD Hyundai's accumulated technologies in ship control, collision avoidance, and optimal route planning. Using this autonomous navigation technology, Avikus achieved the world's first transoceanic voyage of a large vessel using autonomous navigation in June 2022. Based on this achievement, Avikus commercialized HiNAS Control, the world's first Level 2 autonomous navigation solution.
Avikus's autonomous navigation technology considers waves, currents, wind, and the vessel's estimated time of arrival (ETA). It calculates and automatically implements engine speeds that minimize fuel consumption, achieving better efficiency compared to conventional constant-speed operation. For example, the system runs faster when weather conditions create less propeller load and avoid excessive speed during high-load conditions, thereby meeting arrival times while reducing fuel consumption.
HiNAS Control provides core functions including fuel savings, route optimization, and collision avoidance. Using AI-based real-time data analysis and decision-making technology, it detects potential risks that human navigators might miss and suggests safe routes to maximize operational efficiency. To date, Avikus has secured orders for HiNAS Control for over 200 vessels and has implemented it in more than 20 vessels.
Avikus is currently developing Level 3 autonomous navigation, aiming for remote control capability without onboard crew. The plan is to design a system that can make independent decisions in complex maritime traffic situations and various weather conditions while providing reliable responses in emergencies.

In September 2022, Avikus also developed NeuBoat, a Level 2 autonomous navigation solution for leisure boats. It makes boat operation accessible even to beginners. Notably, it provides an automatic docking function, addressing a common challenge faced by many boaters.
Following NeuBoat, Avikus launched NeuBoat Dock in September 2023. Developed in collaboration with global marine electronics company Raymarine, NeuBoat Dock provides more precise collision avoidance and docking assistance through six multifunction displays.

While HiNAS Control and NeuBoat can be applied to vessels regardless of type or form, the number and placement of sensors vary depending on vessel size. Additionally, as ship dynamics differ by vessel type and form, parameter optimization through simple testing is required after system installation.
Ghost Fleet: Unmanned Surface Vehicles and Underwater Vehicles
From surface to underwater, unmanned maritime systems are emerging as a new strategic concept for future naval warfare. Nations worldwide aim to enhance combat effectiveness and minimize human casualties by operating Ghost Fleets—naval vessels equipped with unmanned technology.
The Republic of Korea Navy is also launching unmanned vessel projects as part of its Navy Sea Ghost combat system, which integrates manned and unmanned forces to prepare for future battlefields. In this context, HD Hyundai Heavy Industries won the contract for the shipborne Unmanned Surface Vehicle (USV) Conceptual Design Project from the Navy in March 2024.
In May 2024, HD Hyundai Heavy Industries unveiled its AI-based USV model for the first time at the AI EXPO for National Competitiveness in Washington, D.C.
The USV TENEBRIS, meaning darkness in Latin, signifies its role in conducting stealthy reconnaissance missions near enemy lines. With a light displacement of 14 tons and a length of 17 meters, TENEBRIS is being jointly developed with AI software company Palantir Technologies, targeting completion by 2026.
Notably, TENEBRIS will incorporate world-class advanced AI technology, including Mission Autonomy through the integration of HD Hyundai Heavy Industries' autonomous navigation and vessel-integrated management system with Palantir's AI platform.

HD Hyundai Heavy Industries is also accelerating the development of Unmanned Underwater Vehicle (UUV) technology.
In May 2024, HD Hyundai Heavy Industries signed a Memorandum of Agreement (MOA) with Daeyang Electric, a global industrial lighting and electronics company, for joint technology development of export-type UUVs.

UUVs perform underwater reconnaissance and surveillance, mine detection and removal, marine environmental data collection, and anti-submarine warfare missions. Currently developed UUVs are limited to restricted operations such as reconnaissance and exploration in stable maritime environments, falling short of manned submarine capabilities. Through this agreement, the goal is to develop a differentiated model leveraging accumulated technology and specific mission module development capabilities.
