DredgeWire Exclusive
By Peter Bowe
What is striking is not simply that three large transactions happened in the same week (all announced in DredgeWire), but that they all point in exactly the same strategic direction: control of the underwater domain through autonomy, sensors, software, and data rather than traditional ships and shipbuilding alone.
The Underwater Arms Race
Three announcements in the past week stand out:
- Fincantieri of Italy announced a €600 million acquisition of four underwater technology companies—Next Geosolutions, WSense, Graal Tech and Defcomm—to create what it calls an “international underwater champion.” The acquisitions span autonomous underwater vehicles and vessels, unmanned surface vessels, underwater communications, marine surveying and subsea engineering.
- Lockheed Martin of the US agreed to acquire Ultra Maritime for approximately $3.45 billion, dramatically expanding its anti-submarine warfare, underwater sensing and acoustic technologies.
- Thales of France launched its takeover of Exail Technologies, one of Europe’s leaders in autonomous maritime drones, underwater robotics and navigation systems, in a transaction valued at roughly €3.9 billion.
Taken together, these transactions represent well over $8 billion committed to maritime autonomy and underwater technology in just a few days.
The global scope and scale of these three major international maritime players makes the impact inescapable. It’s earth- shattering (or should I say “sea-shattering”?) in its simultaneous timing, but it makes sense.
More Than Shipbuilding
For decades the maritime industry measured strength in steel: larger shipyards, bigger vessels, and with a focus on tonnage output. These three new deals suggest just how much competitive advantage is shifting toward intelligence and technology rather than tonnage.
Each acquisition targets companies whose principal assets are software, sensors, autonomous vessels, communications or underwater data. In effect, the major defense primes and shipbuilders are purchasing digital capability rather than simply manufacturing capacity. We should add human capital to the list of principal assets as the acquired companies are more into PhD‘s and engineers and R&D than fitters and welders.
This mirrors what has already happened in aerospace, where software and autonomous systems have become as important as aircraft themselves.
Why Now?
Several forces are converging.
First, the wars in Ukraine and the Middle East have demonstrated the military effectiveness of relatively inexpensive autonomous systems. While aerial drones have captured headlines, naval planners increasingly recognize that the next competition will occur beneath the ocean’s surface. Submarine vessels, both manned and, increasingly, unmanned, may be the last surviving military vessels, in every sense of the word. Perhaps we can imagine that the era of super carriers is finite? I think it is.
This past weekend the US Navy deployed sea drones from Saronic against Iranian targets.
Cynthia Cook, an expert on naval drones at the Center for Strategic and International Studies said “The U.S. military’s first combat use of one-way attack sea drones is another example of how wartime drives rapid adoption of new capabilities.” And Saronic, less than five years old, now has an implied valuation of over $9 billion after a recent capital raise!
Second, governments are becoming increasingly concerned about protecting critical underwater infrastructure. Pipelines, telecommunications cables, offshore energy facilities and ports have become strategic national assets. Retired US General David Petraeus reiterated this point in a co-authored WSJ op-ed last week calling ports “strategic terrain.”
Monitoring thousands of miles of seabed is impossible with conventional patrol vessels alone; autonomous surface and underwater systems offer persistent, cost-effective surveillance. Not just the recent mining of the Strait of Hormuz but the bombing of the Nord Stream gas pipelines in 2022 is fresh on the minds of every naval planner—not to mention the Ukrainians’ success against the Russian Black Sea fleet with autonomous vessels.
Third, commercial applications are expanding rapidly. Offshore wind, subsea mining, cable installation, environmental monitoring and hydrographic surveying all depend on autonomous underwater technologies that reduce cost while improving safety. Royal IHC has trumpeted new remote deep sea machines for this market. Even traditional underwater oil and gas production, think of the Gulf, benefits from these technologies.
Implications for the Maritime Industry
These transactions should be viewed as an early signal of where investment capital is heading.
Traditional shipbuilders are evolving into integrated maritime technology companies. Defense contractors are broadening beyond weapons platforms into autonomous maritime ecosystems. Increasingly, future value will reside not only in the ship itself but also in the network of autonomous vessels, underwater communications, artificial intelligence and sensor fusion that surround it.
For the dredging, offshore construction, and marine infrastructure sectors, the message is equally important. Technologies originally developed for defense inevitably migrate into commercial markets. That certainly has been the case in aerospace. Autonomous survey vessels, robotic inspection systems, underwater communications and persistent monitoring will become standard tools for ports, dredging contractors and offshore developers. This is not an advertisement, and perhaps a bit of tooting our own horn, but it’s not a coincidence that companies like HYPACK, Greensea IQ, Arc Surveyors, and GLDD, all of which can claim some participation in this space, have been active supporters of this DredgeWire newsletter. They see the future of maritime.
History shows that major technological transitions often become obvious only in retrospect. Last week’s announcements will ultimately be remembered as one of those inflection points. Three separate companies, in three separate transactions, in three separate countries reached the same conclusion: the next strategic frontier is not just the ocean—it is beneath it.
