A new trend in naval warfare is unilateral attack autonomous underwater vehicles (OWA-AUV). These armed underwater vehicles combine the autonomy and range of an AUV with a torpedo-like warhead. Because of their low speed, they are mostly used to attack relatively static targets, such as ships in port or at anchor, as well as offshore infrastructure.
Where did these drones come from? Several countries and non-governmental organizations already use such devices. As in many other aspects of unconventional naval warfare, the great powers and the West in general are lagging behind in this area. There were predecessors, such as torpedoes, which were launched into ports to damage ships. I suspect that at least one western navy used a similar type of weapon without attracting much public attention. However, this trend is really new and relevant, partly due to the improvement of unmanned underwater technologies.
How effective are these drones? One might be tempted to compare them to the underwater equivalent of the Shahed drones launched in Ukraine. However, in the naval theater of war, more emphasis is placed on surprise and stealth than on quantity. These drones are effective due to their ability to stealthily approach targets and cause significant damage to critical enemy infrastructure.
How they affect modern warfare. The use of underwater attack drones changes the approach to naval operations, making them more unpredictable and dangerous for the adversary. These devices can force the enemy to spend more resources on the defense of ports and other important facilities, which in turn changes the distribution of forces and affects the overall military strategy.
(MARICHKA) — The new large autonomous underwater vehicle (UAV) developed by AMMO Ukraine has a length of approximately 6 meters and a diameter of 1 meter. The design of the device is metal, and the entire body or most of it is a pressure tank. The warhead is located inside the main fuselage.
The smallest OWA-AUV to date was presented for the first time by Ukrainian engineers. Its design is unconventional, which emphasizes its uniqueness. The device is equipped with larger stabilizers and much wider propulsors (propellers) compared to other UUVs. Its range and warhead are smaller than other types.
This torpedo weapon first appeared in May 2021, but gained significant attention during the 2022 conflict. Management can either be internal or at least very limited after launch. Due to its relatively small size, Hamas can launch it from the beach with the participation of four people.
In essence, it is a combination of Unmanned Underwater Vehicle (UUV) and torpedo technology. Over the past few years, there have been attacks on merchant ships in the Persian Gulf attributed to the IRGC (Islamic Revolutionary Guard Corps). Some of these attacks involved ships at anchor and are believed to have involved similar drones.
Developed for the IRGC (Islamic Revolutionary Guard Corps), which has been actively engaged in naval hybrid warfare in recent years. This device is much larger than an ordinary torpedo, which gives it a much longer range, which is at least 500 km. Works on electricity, and most of the fuselage is occupied by lead-acid batteries.
Designed for a variety of tasks, including reconnaissance, monitoring and protection of underwater objects. “Heil” is characterized by high autonomy and the ability to work in difficult underwater conditions. Thanks to advanced technologies and modern sensors, the drone is able to collect and transmit data in real time.
