Anduril and Ultra Maritime Announce Exclusive Partnership on Groundbreaking Autonomous Ocean Sensing Capability

BRAINTREE, Massachusetts – Anduril Industries and Ultra Maritime are proud to announce an exclusive partnership to develop a significant new capability in next generation unmanned subsea sensing, making it possible for U.S. and allied nations to enhance their submarine detection capabilities rapidly and inexpensively. By bringing together Ultra Maritime’s innovative Sea Spear deployable acoustic arrays and AI enabled acoustic processing with Anduril’s undersea autonomy capabilities, including Dive XL and Seabed Sentry, plus Anduril’s Lattice communications framework, the partnership will provide a major advance in distributed, low-cost undersea surveillance.

As enemy submarines grow quieter and greater in number, the need for low-cost solutions to submarine detection grows. Autonomous systems provide a clear path to low-cost, low-risk anti-submarine warfare (ASW) capability, but have to date been hampered by inadequate technology. Issues of range, endurance, sensitivity, communication, scale and more have limited advances in autonomous or uncrewed ASW. Anduril and Ultra Maritime have developed an innovative approach to make autonomous undersea ASW possible.

The concept uses Anduril’s Dive XL to autonomously deliver and deploy Anduril’s Seabed Sentry modular undersea payload system, which in turn hosts Ultra Maritime’s Sea Spear lightweight sensing array as a payload. Once deployed, Sea Spear pushes Sonar processing to the tactical edge using modern AI techniques. The system then uses acoustic communications and Anduril’s Lattice framework to provide users real time, autonomous submarine sensing. Multiple systems can be deployed in a distributed manner, enabling a user to see detects distributed across large ocean areas. The joint effort is well underway and achieves end to end in-water testing in 2025.
