How AUV62-AT Is Transforming Submarine Simulation for the Royal Australian Navy

The Royal Australian Navy has expanded its arsenal of training tools by acquiring additional units of the AUV62-AT, an advanced autonomous underwater vehicle designed to simulate submarines and other underwater threats. This system plays a crucial role in anti-submarine warfare (ASW) exercises, allowing naval forces to conduct realistic training without the need for deploying actual submarines. By using AUV62-AT, the Navy significantly reduces operational costs and conserves valuable resources while maintaining high training standards.

The AUV62-AT is engineered to mimic the acoustic and movement profiles of submarines, torpedoes, and unmanned underwater vehicles. Its ability to replicate these threats with precision enables ASW teams to practice detection, tracking, and engagement in a controlled environment. This not only enhances readiness but also allows for repeated drills without the logistical complexity of involving manned submarines.

One of the key advantages of the AUV62-AT is its versatility across multiple domains. It can be deployed from surface ships, aircraft, or even submarines, making it suitable for a wide range of ASW platforms. The system can be programmed for various training levels, from basic introductory exercises to complex, multi-threat scenarios that challenge seasoned operators.

Powered by an electric motor coupled with a pump-jet drive, the AUV62-AT offers quiet propulsion and efficient maneuverability underwater. This propulsion system is ideal for simulating the stealth characteristics of modern submarines, providing a realistic target for sonar operators and tactical teams. The modular design of the vehicle further enhances its adaptability, allowing operators to configure it for specific mission profiles or training objectives.

Weighing approximately 700 kilograms and measuring over four meters in length, the AUV62-AT is compact yet robust enough to endure demanding underwater conditions. Its diameter of around 0.5 meters makes it hydrodynamically efficient, enabling smooth movement through water at various speeds. The vehicle’s operational depth range of 0 to 300 meters allows it to simulate threats across the full spectrum of underwater combat environments.

In terms of endurance, the AUV62-AT is capable of sustained operations tailored to different training needs. It can operate for up to three hours at a speed of 10 knots, nine hours at 6 knots, and an impressive 18 hours at 3 knots. These endurance profiles ensure that the vehicle can support extended training sessions without interruption, providing consistent performance throughout.

The AUV62-AT is equipped with a range of sensors and masts mounted on its upper section, which contribute to its ability to simulate realistic threat signatures. These components allow it to emit acoustic signals and other cues that mimic those of actual submarines, enhancing the fidelity of training scenarios. Additionally, the lower section of the vehicle contains sensitive areas that can be used to simulate damage or mission-critical systems, adding complexity to engagement exercises.

A notable feature of the AT model is its extendable tail section, which allows it to more accurately replicate the silhouette and hydrodynamic behavior of a real submarine. This enhancement improves the realism of visual and sonar detection training, helping operators refine their skills in identifying and classifying underwater contacts. The tail extension also contributes to the vehicle’s stability and maneuverability during high-speed operations.

By integrating the AUV62-AT into its training programs, the Royal Australian Navy demonstrates a commitment to innovation and operational excellence. The system supports a wide array of tactical scenarios, from single-unit drills to coordinated fleet exercises involving multiple ASW assets. Its reliability and configurability make it a valuable tool for maintaining combat readiness in an increasingly complex maritime security environment.
