Teledyne Marine, known for its work in unmanned underwater vehicles and high, end ocean tech, joins forces with M Subs, a British firm deep into autonomous sea systems, through a newly signed agreement meant to shape future naval missions. Instead of going solo, both companies lean on shared goals laid out in a Memorandum of Understanding aimed at pushing how undersea tasks are handled. While each keeps its edge, their path now runs parallel, building something tighter than before. Behind the scenes, planning kicks off without fanfare, targeting real shifts in how machines operate below the surface.
Working together, each group adds what the other lacks, aiming at chances tied to the Royal Navy along with various global naval efforts. At its core, this alliance focuses on blending smart vehicle bases with automated guidance setups, sound, based detection tools, underwater signal transfer, visual gear, illumination methods, plus links that work below the surface, shaping practical, strong ocean, ready results.
Right now, tech tasks are moving forward, Teledyne SeaBat sonars were recently tested on Zero USVs at REPMUS 2025, working just as needed. At the same time, teams began setting up ways to launch Slocum gliders along with Osprey, class AUVs using those same unmanned boats. Real, world tests will happen early next year, one in the UK, another in Iceland, both set before mid, 2026 wraps up.

Key highlights of the partnership include:
Firm ties to Royal Navy efforts grow through shared work on key missions. Projects could include combined moves around Atlantic Bastion along with MHC Block 2 steps forward. Strength comes from solid UK footing, drawing on field skills each firm brings in turn. Teledyne plus M Subs stand ready, rooted in real practice and local reach.
Together, theyll track down fresh international prospects in defense and sea safety. Spotting potential projects comes next, followed by shaping them into real plans. One step at a time, their teams will line up chances worth chasing. Qualifying each opening happens before any move forward. Joint efforts steer how both sides push ahead.
One team brings sensors, another handles navigation, between them, smarter sea drones take shape. Expertise overlaps where machines think for themselves on open water. Engineering strengths link up, making vessels respond better during operations. When knowledge pools, results move beyond what single groups achieve alone.
Brian Maguire, Teledyne Marine Chief Operating Officer and Vehicles General Manager, stated, “This collaboration represents a significant step forward in advancing maritime technologies. By combining our expertise, we aim to deliver innovative solutions that meet the evolving needs of the UK and international markets.”
Brett Phaneuf, Director of M Subs, added, “It has been a pleasure to work with Teledyne to integrate the myriad sensors and devices they bring to bear on the marine and defense space; they have proved nimble and forward leaning in our work together, necessary qualities from flagship companies partnered with small SMEs for us to be successful in the future when serving the nation…it’s also been a great deal of fun.”
Through this strategic partnership, Teledyne Marine and M Subs aim to speed up the pace of innovation and provide high technology-readiness products for both defense and commercial maritime markets.
