Saildrone and Thales engineers look at a detection event during structured testing of the Saildrone Surveyor equipped with a Thales BlueSentry thin-line towed array.

Saildrone, a world leader in maritime autonomy, in collaboration with Thales Australia, has successfully demonstrated the integration of the BlueSentry thin-line towed array with the Saildrone Surveyor, creating a groundbreaking system for autonomous long-endurance undersea maritime domain awareness (MDA). The project, funded by the Office of Naval Research (ONR), marks a significant leap forward in persistent, real-time, undersea surveillance.

Extensive sea trials conducted off the coast of California have demonstrated that this system can effectively detect and classify both underwater and surface threats and report this information to decision makers in real time. During the ONR trial, the Saildrone Surveyor and BlueSentry system operated continuously for 26 days and maintained uptime greater than 96%. 

“The acoustic performance of the BlueSentry array, paired with a platform as silent and capable as the Saildrone Surveyor, represents a considerable step forward in undersea observation,” said Richard Jenkins, founder and CEO of Saildrone. “The extreme endurance of the system allows us to put eyes and ears in places that were previously out of reach, at a cost point orders of magnitude below traditional manned surveillance platforms.”

The trials showed that, under wind propulsion, the Surveyor provided a near-zero self-noise environment, significantly improving the detection capabilities of the BlueSentry sonar system. Utilizing Starlink and Iridium satellite communications, the system is capable of persistent, secure data transmission, supporting real-time decision-making from remote locations worldwide.

“This partnership and ready-to-deploy capability set the standard for future intelligence, surveillance, and reconnaissance at sea, particularly in sensitive and remote regions that have significant operational challenges,” said Jeff Connolly, CEO, Thales Australia and New Zealand. “The integration of Thales Australia’s BlueSentry onto Saildrone's Surveyor-class, as a core component of its maritime domain awareness solution, paves the way for greater naval interoperability between AUKUS partners and delivers on AUKUS Pillar 2 undersea warfare requirements.”

Saildrone and Thales Australia stand ready to deploy these systems at scale, creating a network of autonomous, self-sustaining surveillance assets to enhance national security. As threats evolve and the demand for persistent undersea awareness increases, the Saildrone-Thales system offers a scalable, low-cost alternative to traditional surveillance platforms.

About Saildrone

Saildrone is a maritime defense and oceanographic survey company creating a paradigm shift in how navies, law enforcement, civil government, and commercial organizations obtain the real-time, accurate data required to monitor and protect our oceans. Saildrone’s fleet of uncrewed surface vehicles (USVs) carries purpose-built payloads supporting border protection, critical infrastructure security, hydrographic survey, offshore energy, and metocean monitoring. Powered by renewable wind and solar energy, Saildrone USVs provide long-duration operations measured in months, not days. Proprietary software applications and machine learning technology transform collected data into actionable insights and intelligence. Saildrone has sailed more than 1,600,000 nautical miles from the High North to the Southern Ocean and spent over 46,000 days at sea in the harshest ocean conditions on the planet.

About Thales Australia

Thales in Australia is a trusted partner of the Australian Defence Force in the Land, Sea, and Air environment. Thales employs over 4,300 people in Australia, across 35 sites and supports over 2,000 jobs along its Australian supply chain. Drawing on over 50 years of Australian Towed Array investment and development, Thales’s BlueSentry utilises acoustic sensor technology trusted by navies around the world to detect, classify, and localise surface and sub-surface contacts.

The BlueSentry towed array integrated on Saildrone Surveyor USVs, designed and manufactured at Thales’s Acoustics Centre of Excellence in Rydalmere, Australia, reflects recent innovations in the field of fibre optics and advanced hydrophone technology.
