Imagine reaching a major turning point in Australia’s efforts to strengthen its naval defenses — and this is exactly what the Hunter-class frigate program has just achieved. But here’s where it gets controversial: the recent success in testing crucial sonar systems for these cutting-edge ships could redefine undersea warfare strategies in the Indo-Pacific region. The milestone in question is the factory acceptance test (FAT) of two key components of the Sonar 2087 suite: the Towed Body Handling System (TBHS) and the Towed Array Handling System (TAHS).
This important test was carried out at Thales Defence Mission Systems’ facility in Brest, France, with a collaborative team from Thales divisions in France, the UK, and Australia, alongside representatives from the Royal Australian Navy. According to Commander Roy Casson of the Naval Shipbuilding and Sustainment Group, the systems and their auxiliary components performed flawlessly, adhering strictly to detailed testing protocols. He emphasized that rigorous oversight from multinational teams assured that the products met their precise design goals and are now poised to provide Australia’s navy with this world-class capability for many years ahead.
The Sonar 2087, developed by the British and based on the Thales CAPTAS-4 system, is an innovative sonar platform combining active and passive arrays. This sophisticated system can detect, locate, and classify submarines at distances reaching up to 60 kilometers — a significant enhancement in underwater detection technology. It provides 360-degree situational awareness and real-time warnings against torpedoes, dramatically boosting the Navy’s anti-submarine warfare abilities.
When integrated into the Hunter-class frigates, the Sonar 2087 isn’t just another piece of kit — it’s part of a comprehensive sensor and weapon suite that creates a formidable underwater defense system. Designed specifically to counter emerging submarine threats, this system will play a vital role in protecting Australia’s maritime interests well into the future.
And this is the part most people miss: with these tests successfully completed, the systems are scheduled for delivery to Australia in the first quarter of 2026. This means they will soon be integrated into the Hunter-class frigates, bringing Australia closer to commissioning these advanced vessels in the early 2030s. Such developments raise questions about regional security dynamics and the evolving nature of submarine warfare — does this move tip the balance of power? Or could it spark a new arms race in underwater capabilities?
