Executive Summary: The Subsurface Paradigm Shift

The maritime domain is witnessing a seismic shift in the subsurface balance of power. The transition from traditional, crewed mine-hunting to autonomous, mothership-led operations is not merely a tactical upgrade; it is a maritime revolution. In the current geopolitical climate, where critical undersea infrastructure (CUI) is the lifeblood of global trade and energy, the old methods of mine countermeasures are as antiquated as a sextant in a satellite world. This shift is the only logical response to increasingly sophisticated, integrated, and autonomous underwater threats that seek to plunge our global economy into the dark of the littoral.

The core value proposition of the “Mothership” concept represents a departure from single-mission hulls toward versatile, high-capacity nerve centers:

Tactical Mass and Standoff: By deploying a “brood” of autonomous systems, the Mothership allows sailors to stay well outside the minefield’s lethal radius while robots handle the “dirty, dull, and dangerous” labor of neutralization.Strategic Flexibility: As evidenced by the HMS Stirling Castle’s delivery of mission kit for the Strait of Hormuz, these vessels are not just platforms; they are logistics powerhouses capable of projecting power across the globe at a moment’s notice.Allied Resilience: Codified through the UK-Norway alliance, the shift toward modular, shared designs like the Kongsberg C2 Vanguard ensures a unified, interoperable force protects that NATO’s Northern Flank.

Navigating this transition requires more than just new hardware; it requires a fundamental change in how we perceive naval presence. We are moving from a world of ships to a world of data-driven sensors.

The Mother ship: From Commercial Workhorse to Naval Nerve Center

Repurposing commercial offshore support vessels (OSVs) like the Island Crown into the HMS Stirling Castle is the height of maritime pragmatism. In a blue-water environment where procurement cycles often move at a glacial pace, the Royal Navy (RN) has cut through the fog by acquiring hulls already optimized for subsea engineering. Some landlubbers have criticized the ship’s initial civilian paint scheme as “unprofessional” or “sketchy,” but to the veteran strategist, this was a triumph of utility over vanity—a grey-paint soul in a civilian skin, serving as a trials platform before her full military refit.

Technical Profile: HMS Stirling Castle (M01)

The table below is the technical profile foHMS Sterling Castle

The transition of the Stirling Castle from the Royal Fleet Auxiliary (RFA) to the RN was not an aesthetic choice; it was driven by a “manpower storm.” With the RFA effectively on its last legs due to a “deeply troubling” crewing crisis, the RN had to take the helm to ensure the ship didn’t sit idle. This move marks the Stirling Castle as a dedicated commissioned warship, shifting from a mere trials boat to a strategic host for a new breed of Deep Armada.

---

The Autonomous Armada: Deploying the Drones of the Deep

The Mothership’s true strength is her ability to facilitate “distributed maritime operations.” She acts as a floating base for an armada that operates beyond the horizon, ensuring that if a drone is lost to a sophisticated mine, the loss is measured in pounds and pence, not lives. The Stirling Castle’s recent delivery of four mine-hunting vessels to Gibraltar for a possible operation in the Strait of Hormuz proves this adaptability—she is a mobile hangar for the underwater front line.

The autonomous armada supported by the Stirling Castle consists of four primary pillars:

Autonomous Underwater Vehicles (AUVs): The REMUS family is the gold standard here. Notably, the REMUS 300 serves as the baseline for the U.S. Navy’s Lionfish program, and we are now seeing these assets tested for submarine torpedo-tube launch, allowing for clandestine deployment from the depths.Unmanned Surface Vehicles (USVs): The ROMULUS family and RNMBs like Apollo and Hazard provide the surface-level coordination, acting as AI-enabled relays for the swarm below.Remotely Operated Vehicles (ROVs): Essential for high-stakes neutralization, these systems allow human operators to perform subsea surgery on fuzed threats from the safety of the Mothership’s mission bay.Modular Mission Payloads: Future-proofing is baked into the design. The “plug-and-play” nature of these platforms means we can swap sensors as fast as thethreat evolves, ensuring the hull remains relevant for decades.

While the physical drones are impressive, they are merely delivery vehicles for the most valuable asset in seabed warfare: high-resolution sonar data.

---

Sonar Technology: The Strategic Advantage of High-Resolution Imagery

In the contested dark of the littoral, data is the only currency with any real value. To detect a mine designed to look like a rock or a fuzed device hidden near a communications cable, you need more than just a ping; you need a “digital twin” of the seafloor. This is where the Royal Navy gains its decisive edge, utilizing open-architecture sonar systems that can be rapidly upgraded to meet new fuzing challenges.

The REMUS Sonar Family provides a tiered capability that defines modern seabed mapping:

REMUS 130/300: These are the agile scouts. Optimized for shallow-water and rapid deployment, they provide immediate situational awareness in the most cluttered environments.REMUS 620: The workhorse of persistent surveillance. With an 110-hour battery life and a 275nm range, it can map vast swathes of the seabed, providing the persistent “eyes” required for infrastructure protection.

This tech isn’t bought blindly. The Dstl (Defence Science and Technology Laboratory) utilized rapid 3D physical modeling to de-risk the procurement of the Stirling Castle, identifying a “key design change” early in the process. This marriage of advanced sonar and analytical de-risking ensures that every byte of data gathered is an investment in maritime security.

The Geopolitical Deep: NATO, Norway, and the North Atlantic

The “Lunna House Agreement” between the UK and Norway is the cornerstone of NATO’s Northern Flank. This isn’t just about joint exercises; it’s about a total integration of defense. From pre-storing British equipment on Norwegian soil to conducting Arctic training across all seasons, the alliance is focused on one thing: ensuring the North Atlantic remains a NATO lake.

The joint procurement strategy, currently assessing the Kongsberg C2 Vanguard design for the next three motherships, offers profound strategic benefits:

Lifecycle Efficiency: Shared design means shared spare parts and training pipelines, reducing the fiscal burden while increasing “combat mass.”Interoperability: A Norwegian USV must be able to launch from a British deck without friction. Modular standards make this a reality.Procurement De-risking: By joining Norway’s standardized vessel program, the UK avoids the “bespoke trap,” getting proven hardware into the water faster.

The future of naval power in the High North is no longer about who has the biggest gun, but who has the most resilient sensor network.

Executive Summary

Russia has learned an expensive maritime lesson: dismissing uncrewed boats as “toys” does not stop them from sinking ships.

Ukraine’s success in the Black Sea forced Moscow to scrape the barnacles of tradition from its naval thinking. Russia is now moving beyond improvised responses and building a domestic ecosystem of uncrewed surface and underwater platforms, supported by Russian-made hulls, propulsion systems, sonar, sensors, and software.

That progress should not be underestimated.

But it should not be exaggerated either.

Russia may be developing the boat and its payload, but it has not yet fully integrated the nervous system that connects them to the operator. Its apparent dependence on foreign satellite communications exposes the difference between building an autonomous-looking platform and fielding a genuinely sovereign autonomous capability.

The hull may be Russian.

The sonar may be Russian.

The communications umbilical cord may still lead somewhere else.

---

Ukraine Changed the Procurement Conversation

The Russian Black Sea Fleet once dominated the region through mass, missiles, and intimidation.

Then comparatively inexpensive Ukrainian drone boats helped push major Russian warships away from Sevastopol and forced them to operate more cautiously from Novorossiysk.

Watching billion-dollar naval assets retreat from expendable boats is not merely embarrassing.

It is doctrinally educational, and I think it surprised everyone.

Russia’s response has moved from dismissal to imitation and now toward institutionalization. Russian industry is presenting multiple USV families, while the navy is establishing dedicated unmanned formations and integrating uncrewed systems into wider maritime operations.

The “mosquito fleet” is no longer being treated as an irritation.

It is becoming part of the fleet.

---

Why I Take Russian Sonar Seriously

When I served in the Royal Swedish Navy, I visited the Central Research Institute Morfizpribor in St. Petersburg several times. This was during a very different period, when professional engagement with Russian organizations was both possible and acceptable.

Morfizpribor was one of Russia’s principal centers for hydroacoustic research and naval sonar development. Those visits gave me a firsthand view of some of the work taking place inside the Russian underwater-technology establishment.

Russia’s technical capabilities have always been uneven. It is not equally good at everything, and glossy claims from its defense industry deserve the same scrutiny as those from any other supplier.

But underwater technology is one area in which Russia has genuine and longstanding expertise.

It builds highly capable submarines.

It also knows how to build sonar, espcially active sonars.

That experience shapes how I view Russia’s current USV sprint. The communications weaknesses are real, but they should not tempt us into dismissing the payloads, or the people developing them.

Russia may be learning some lessons from Ukraine.

It is not starting from zero underwater.

---

The Domestic Payload Sprint

Western sanctions have made dependence on imported maritime technology increasingly dangerous. A foreign component is not merely a supply-chain inconvenience when it can be blocked, unsupported, or remotely constrained.

It can become a mission failure waiting to happen.

Russia’s answer has been localization.

The compact Orkan USV is intended for hydrographic, research, and patrol missions and is presented with domestic sonar equipment.

The heavier Vizir and Vizir-2M, developed by the Kingisepp Machine-Building Plant, illustrate the value of modular payload architecture. Depending on configuration, the platform can reportedly carry Russian anti-submarine sonars, multibeam echo sounders, and side-scan sonars for seabed mapping, object detection, and target classification.

The small MPA ROV from JSC GIPP Region follows the same logic below the surface. Its modular search configuration is intended for locating and classifying underwater objects, with a search package reported to include side-scan sonar.

These platforms represent an effort to control more of the capability chain domestically.

That distinction matters.

A USV is not a capability simply because it can leave the pier without a crew.

The useful capability comes from what it can sense, how it interprets the environment, how reliably it communicates, and what decision or action its payload enables.

The boat is transportation.

The payload is the mission.

---

The Communications Umbilical Cord

Russia appears increasingly capable of producing hulls, engines, waterjets, navigation systems, and conventional sonar payloads domestically.

Long-range, high-bandwidth satellite communications remain a more difficult problem.

The Murena-300S exposed that weakness rather publicly. Imagery of the platform showed what analysts identified as a possible Starlink antenna concealed beneath camouflage netting.

Rassvet (“Dawn”) is Russia’s emerging Starlink-style satellite-internet constellation, developed by Bureau 1440. It uses low-Earth-orbit satellites and phased-array user terminals to provide lower-latency broadband connectivity, with planned 5G non-terrestrial-network integration. Initial operational satellites launched in 2026, but coverage remains limited and the system is still in early deployment rather than a mature, global service. Russia aims to build several hundred satellites by 2027–28 and roughly 900 by 2035, leaving Rassvet well behind Starlink’s current scale and operational maturity.

Rassvet is critical, as without resilient beyond-line-of-sight communications, transmitting sonar data, updating missions, maintaining human control, and conducting terminal guidance become much harder.

Autonomy can reduce that dependence, but only by transferring more judgment onboard.

That requires processing power, reliable software, environmental understanding, target-classification confidence, and clearly defined rules for what the platform may do when communications disappear.

Removing the operator from the boat does not remove the operational decisions.

It merely moves them somewhere else.

---

A Warning Beyond Naval Warfare

The explosive maritime drone intercepted near Romania’s Neptun Deep gas project on 20 August demonstrated how even a drifting USV can create strategic effects. A Romanian F-16 engaged the vessel before explosive-ordnance personnel neutralized it near critical offshore infrastructure.

Such platforms do not always need to strike their targets to succeed.

They can force defensive deployments, interrupt operations, increase insurance costs, test rules of engagement, and create uncertainty around offshore energy infrastructure.

Sometimes the strategic payload is not the explosive charge.

It is doubt.

---

Summary

Russia’s maritime-drone sprint is real. Its domestic sonar and sensor programs demonstrate growing industrial resilience, while its unmanned formations suggest these systems are becoming permanent naval tools.

But autonomy is a chain, and the weakest link may not be the hull or even the sonar. It may be communications, integration, processing, or operator trust.

That is the lesson for every autonomous-platform program:

Do not begin by asking which boat to buy.

Begin by asking what the mission must detect, understand, communicate, and enable.

At Strategic Sonar Solutions, we help organizations translate missions into defensible payload requirements and select the sonar, sensors, processing, and supporting systems that make autonomous platforms operationally useful.

If you are designing an autonomous platform—or wondering whether its proposed payload is genuinely fit for purpose—let’s talk before an impressive technology demonstration becomes an expensive integration problem.

Executive Summary

On July 6, 2026, Canada selected TKMS as the preferred supplier for up to twelve Type 212CD submarines. A final contract has not yet been signed, but negotiations are expected to conclude by the end of 2027, with the first four submarines scheduled for delivery in 2034.

Canada chose more than a German submarine.

It chose entry into an established German-Norwegian program, an active production line, NATO standardization, earlier delivery, and a long-term industrial partnership.

The platform is important. The sonar architecture may be even more important.

The Canadian system is expected to combine German passive acoustic technology from ATLAS Elektronik, Norwegian active sonar, navigation and processing technology from Kongsberg, and a growing Canadian contribution in software, secure information management, training and sustainment.

As a former Royal Swedish Navy submariner (bubble head), I look at submarines differently from most procurement analysts. Sonar is not another subsystem on the equipment list.

It is how the boat sees, survives and fights.

Why Canada Chose the German Path

Canada needed more than a replacement for four aging Victoria-class submarines. It needed enough boats to cover the Atlantic, Pacific and Arctic while still allowing for maintenance, training and crew development.

The 212CD offered a difficult combination to beat: long submerged endurance, reduced acoustic and magnetic signatures, Arctic suitability, NATO interoperability and a credible delivery schedule.

Canada will also join Germany and Norway as a partner in a common submarine program. That brings opportunities for shared logistics, training, upgrades, supply chains and operational experience. Kongsberg describes Canada as becoming an equal partner in the established 212CD cooperation.

Both TKMS and South Korea’s Hanwha Ocean reportedly met the Royal Canadian Navy’s operational requirements. The decision therefore extended beyond speed, displacement and weapons.

Canada selected the alliance structure it wanted supporting its submarine force for the next forty years. The German offer combined capability with NATO standardization, early delivery and extensive industrial participation.

The German Ears

ATLAS Elektronik is expected to anchor the passive side of the combat-sonar architecture.

The final Canadian configuration has not been publicly released, and this distinction matters. The preferred-supplier announcement begins negotiations. It does not freeze every sensor, processor or array into the Canadian design.

The likely ATLAS contribution is a version of the CSU100, which includes conformal passive arrays around the bow and flank arrays, supplemented by aft coverage and a low-frequency towed array. ATLAS offers configurable submarine sonar architectures covering passive surveillance, active detection, tracking and the full relevant frequency range.

Passive sonar allows the submarine to detect and classify contacts without announcing its own position. But installing hydrophones is the easy part.

Controlling self-noise, calibrating thousands of channels, separating machinery from targets and converting weak bearings into reliable tracks is where real acoustic experience becomes valuable.

The Norwegian Contribution

Kongsberg provides much of the active sonar, navigation and processing layer.

The common 212CD package includes the SA9510S Mk II mine-avoidance and navigation sonar. It looks ahead of the submarine for mines, obstacles and dangerous seabed features, providing enough warning for the commanding officer to manoeuvre safely.

Kongsberg’s package also includes the EM2040 MIL multibeam echo sounder and EA640 echo sounder suite for seabed mapping and bottom-referenced navigation. These sensors feed the ORCCA navigation system, supporting submerged operations where GPS is unavailable.

Kongsberg also supplies major elements of ORCCA, the integrated combat system developed through kta naval systems, the joint venture involving TKMS, ATLAS Elektronik and Kongsberg. ORCCA connects sonar, navigation, weapons and tactical information at the operator console. Kongsberg’s processing technology can interface with passive arrays and perform conventional, adaptive and advanced beamforming.

ATLAS helps the submarine listen.

Kongsberg helps it process, navigate and act.

The Canadian Sonar Layer

Canada’s contribution may be less visible than a bow array, but it could become more strategically important.

Kongsberg Geospatial in Ottawa has already contributed more than 50,000 hours of Canadian software development to ORCCA. The partnership also proposes a Canadian combat-management-system centre of excellence supporting the Canadian fleet and future TKMS submarines.

Canadian company Cohere is working with TKMS on secure information management, decision support, training and naval interfaces. CAE is positioned to deliver submarine training and simulation, while Seaspan would support a Canadian-led sustainment enterprise.

Canada’s most valuable acoustic contribution may therefore lie in software, operator interfaces, training data, mission libraries and future system upgrades.

Canada must also ensure that the sonar architecture can evolve for Arctic propagation, overhead ice sensing and Five Eyes data exchange. Buying advanced hardware is not enough if Canada cannot modify the processing, update threat libraries or control its acoustic data.

Key Points

Canada chose the 212CD for capability, delivery, NATO interoperability and long-term partnership.ATLAS is expected to anchor the passive combat-sonar architecture.Kongsberg provides active mine avoidance, seabed navigation, processing and key ORCCA elements.Canada’s strongest contribution will be software, training, secure interfaces, sustainment and future Arctic adaptation.

Call to Action

Canada should not measure domestic content by tonnes of steel, factory floor space or the number of maintenance contracts.

It should measure acoustic sovereignty by who controls the raw sonar data, who can modify the algorithms and who can update the threat libraries during a crisis.

A submarine built in Germany can still become a sovereign Canadian capability.

A sonar system that Canada cannot understand or change never will.

eBOSS vs. Kraken Acoustic Corer vs. Fraunhofer Manta Ray

Executive Summary

We have spent decades mapping the seabed. The next contest is underneath it.

That distinction becomes expensive very quickly when a monopile hits a buried boulder, a cable route intersects old infrastructure, or a suspicious acoustic return turns out to be UXO. Traditional sub-bottom profilers still have an important role, but major offshore projects increasingly want more than a vertical slice through sediment. They want a three-dimensional answer.

Three technologies illustrate where the market is going: EdgeTech eBOSS, Kraken Robotics’ Acoustic Corer, and Fraunhofer IWES’ Manta Ray diffraction-imaging approach.

They are often grouped together as advanced sub-bottom systems. I think that oversimplifies the comparison.

Each attacks a different problem:

· eBOSS focuses on relatively shallow buried-object detection and classification.

· Kraken performs highly detailed volumetric interrogation of specific foundation locations.

· Fraunhofer goes after deeper geological hazards, especially buried boulders, using ultra-high-resolution seismic diffraction imaging.

The most expensive sonar is still the wrong sonar.

---

EdgeTech eBOSS: Hunting What the Seabed Is Hiding

EdgeTech’s eBOSS, or Buried Object Sonar System, grew from work aimed at one of the harder acoustic problems in the marine environment: detecting and classifying objects that are not sitting neatly on the seabed.

The commercial eBOSS uses dual broadband projectors operating in the 5 to 25 kHz range together with 3D sub-bottom SAS processing and beamforming. It is designed to create detailed imagery of buried objects while the system is moving.

Its heritage is particularly interesting for UXO work.

A traditional acoustic system can struggle when a cylindrical or elongated target is viewed from an unfavorable aspect. The return changes. Acoustic shadows change. Classification confidence drops.

Research associated with the eBOSS development program looked at solving this by illuminating targets from multiple acoustic perspectives. That work points toward a future where acoustic data alone may provide enough information to classify buried UXO without always requiring another sensor pass.

That is potentially a major operational advantage.

Pros: Mobile, good coverage rate, high-resolution buried-object imaging, strong fit for UXO, cable and pipeline work.

Cons: Penetration is relatively shallow compared with Kraken and Fraunhofer. It is not the system I would select for deep geological characterization.

Best use: UXO investigation, buried cables, pipelines, route surveys and shallow critical underwater infrastructure.

---

Kraken Acoustic Corer: Stop Moving and Look Harder

Kraken approaches the problem very differently.

Instead of surveying continuously along a route, the Acoustic Corer is deployed at a specific location and performs an intensive volumetric interrogation of the seabed.

The system combines high-frequency chirp, low-frequency chirp and parametric synthetic aperture techniques to generate a three-dimensional acoustic volume around the deployment point. Published material describes an acoustic core roughly 14 meters in diameter with penetration that can exceed 50 meters in favorable geology.

This makes the system particularly interesting around monopile foundations, jackets, offshore substations and other locations where a single buried obstruction can become extremely expensive.

The strength of Acoustic Corer is detail.

Kraken has demonstrated its ability to identify buried boulders, linear objects and geological structures that could affect construction. This is where the technology starts to close the traditional gap between geophysics and geotechnics.

Instead of asking, “What might be underneath this proposed pile location?” the objective becomes, “Show me the three-dimensional volume underneath this exact location.”

That is a very different level of confidence.

The trade-off is operational complexity.

This is not a small sensor that you casually bolt onto a USV. Acoustic Corer requires significant vessel support, lifting capability and specialist personnel.

Pros: Excellent 3D visualization, deep penetration, strong foundation de-risking capability.

Cons: Heavy operational footprint, slower area coverage, specialized deployment.

Best use: Offshore foundations, construction risk reduction, detailed geohazard investigations and high-value sites where uncertainty is unacceptable.

---

Fraunhofer Manta Ray: A Technology I Know From the Other Side

Fraunhofer IWES takes yet another route.

Its Manta Ray development focuses on ultra-high-resolution seismic diffraction imaging. Instead of concentrating primarily on conventional seismic reflections, the processing exploits the diffraction energy created around small buried geological objects.

This is particularly powerful for detecting boulders.

Fraunhofer has reported the localization of buried boulders at substantial depths, in some cases approaching 100 meters below the seabed. That makes the technology especially relevant to offshore wind development, where deeply buried glacial material can create serious problems during foundation installation.

This part of the comparison is also personal for me.

During my time as Chief Business Development Officer at MIND Technology, I was involved in supporting the streamer technology supplied to Fraunhofer’s work. My role was on the commercial and technology side rather than in the scientific development of the imaging algorithms, but it gave me a close view of what Fraunhofer was trying to achieve.

What interested me then, and still does, was the combination of a relatively conventional seismic acquisition concept with very unconventional synthetic aperture processing.

The value is not simply producing another seismic section. It is extracting information from diffraction energy that older workflows often treated as noise.

That is clever.

And for offshore construction, it can be extremely valuable.

Pros: Deep penetration, excellent boulder localization, efficient area coverage, strong fit for offshore wind site characterization.

Cons: Less suited to small UXO-style object classification. It is a geological and construction-risk tool first.

Best use: Offshore wind development, deep boulder risk, cable corridors and early-stage foundation planning.

---

The Strategic Pings Comparison

So Which One Wins?

None of them.

That is the point.

If I am clearing a cable corridor where UXO and buried infrastructure are the primary risks, eBOSS gets my attention.

If somebody is preparing to install a high-value offshore structure and needs maximum confidence underneath a specific foundation, Kraken Acoustic Corer belongs in the discussion.

If the primary concern is deep boulder risk across an offshore wind development, Fraunhofer’s diffraction-imaging approach is extremely compelling.

In fact, the most intelligent survey architecture may combine them.

Fraunhofer can characterize the broader geological risk. Kraken can investigate the critical foundation positions in far greater detail. eBOSS can attack shallow buried-object and UXO problems along cable routes and construction corridors.

That is where this gets interesting.

The future is probably not one sonar replacing another. It is choosing the right level of acoustic intelligence at the right stage of the project.

---

Summary

The sub-bottom market is moving away from simple profiling and toward increasingly sophisticated 3D interrogation.

EdgeTech eBOSS brings mobility and buried-object resolution. Kraken Acoustic Corer brings intense site-specific volumetric imaging. Fraunhofer Manta Ray brings deep seismic diffraction imaging across larger areas.

Three technologies. Three different missions.

Trying to declare one universally superior misses the operational reality.

The seabed is becoming crowded. The sub-seabed is becoming expensive.

And discovering that you selected the wrong sensor after construction starts is a particularly painful way to learn about acoustics.

This is exactly where Strategic Sonar Solutions Inc. fits.

Executive Summary

The U.S. Navy’s selection of Kongsberg’s HUGIN and Oceaneering’s Freedom under its Large Displacement Unmanned Underwater Vehicle (LDUUV) effort signals something more important than another autonomous-vehicle trial.

The Navy is evaluating two fundamentally different approaches to undersea perception.

HUGIN is optimized to search large areas, accurately map the seabed, and classify objects at operationally useful ranges. Freedom is designed to maneuver close to subsea infrastructure, inspect complex geometry, and autonomously investigate anomalies.

One is an acoustic surveyor. The other is an acoustic inspector.

The provocative question is therefore not which vehicle is better. It is whether the Navy has finally recognized that no single sonar architecture can efficiently perform every undersea mission.

From Commercial Maturity to Naval Capability

In February 2024, the Defense Innovation Unit awarded Kongsberg a 24-month contract supporting the Navy’s LDUUV prototype effort. The agreement contemplated HUGIN Superior and, potentially, the larger HUGIN Endurance. Oceaneering was also selected to develop and test Freedom, followed by an October 2024 contract to build a vehicle and establish an Onshore Remote Operations Center.

The selection logic is clear: both companies offered mature commercial technology, existing supply chains, proven autonomy, and operational experience accumulated outside the traditional naval acquisition system.

That matters. The Navy is not paying industry to invent an AUV from a blank sheet of paper. It is importing systems already shaped by deep-ocean survey, offshore-energy inspection, and demanding commercial operations.

Kongsberg subsequently delivered the first HUGIN Superior after acceptance testing in early 2025. Contrary to some reporting, the vehicle publicly confirmed as delivered was HUGIN Superior, not HUGIN Endurance. Kongsberg describes the delivered system as immediately relevant to mine countermeasures, seabed warfare, infrastructure inspection, and Intelligence Preparation of the Operational Environment.

HUGIN: Wide-Area Acoustic Intelligence

HUGIN Superior’s primary acoustic instrument is the dual-receiver HISAS 1032 synthetic-aperture sonar.

Unlike conventional side-scan sonar, whose along-track resolution deteriorates with range, SAS combines multiple spatially separated pings into a much longer virtual array. The result is approximately 5-by-5-centimeter imagery at 200 meters, with useful operation extending to 500 meters at lower vehicle speeds.

This is not simply “better sonar imagery.” It changes mission economics.

HISAS can search and classify across a broad corridor while maintaining nearly range-independent along-track resolution. Its interferometric processing also produces bathymetry, connecting the acoustic image to three-dimensional seabed structure.

The accompanying EM 2040 MkII multibeam echo sounder operates at 200, 300, or 400 kHz and provides wide-swath bathymetry, multiple detections, and water-column recording. A sub-bottom profiler examines sediment layers below the seabed, while forward-looking sonar supports terrain following, obstacle avoidance, and under-ice operation. The HUGIN Superior specification shows how these sensors form a complementary acoustic stack rather than a collection of unrelated payloads.

HUGIN’s focus is coverage, geolocation, and classification: find the object, position it accurately, and place it within the wider operational environment.

Freedom: Close-Range Acoustic Inspection

Freedom approaches the problem differently.

Its eight-thruster architecture provides six-degree-of-freedom control, allowing the vehicle to stop, hover, reverse, orbit, and maintain a precise inspection geometry. This makes it particularly valuable around pipelines, cables, structures, and other confined or geometrically complex targets.

Payload configurations (according to my sources) combine SeaBat T20 multibeam sonar, Voyis Observer Pro Camera and Laser scanning, and Sonardyne SPRINT-Nav acoustic-inertial navigation. Freedom has demonstrated pipeline tracking at altitudes as low as three to five meters and can gather detailed inspection data in a single pass.

Its COMPASS software analyzes sonar and computer-vision data onboard. When it detects a free span, burial, crossing, or other anomaly, the vehicle can trigger a closer inspection behavior instead of blindly completing a pre-programmed survey line. Oceaneering describes this as feature-based navigation.

The exact payload configuration of the Navy vehicle has not been publicly disclosed. What the commercial baseline demonstrates, however, is a shift from sonar as a passive data collector to sonar and laser as an input to autonomous decision-making.

Strategic Summary

HUGIN is built to answer: What is on the seabed, and where is it?

Freedom is built to answer: What is happening to this specific object, and should I investigate further?

That distinction matters. The future of undersea autonomy will not be decided by vehicle endurance alone. It will be decided by how intelligently platform dynamics, navigation accuracy, sonar frequency, aperture, coverage, processing, and mission logic are engineered as one system.

A poorly matched payload turns even an excellent AUV into an expensive data-collection exercise.

If you are developing or procuring an uncrewed maritime platform, I help organizations select and integrate the right payload for the right vehicle and mission, from sonar architecture and navigation performance to power, data, autonomy, and operational trade-offs.

Message me with PAYLOAD if you want to discuss what your platform actually needs to sense beneath the surface.

Executive Summary

Kraken Robotics did not simply acquire another underwater technology company. It acquired many of the building blocks required to create a complete subsea intelligence system.

With Covelya Group, Kraken gains underwater navigation, acoustic positioning, communications, survey software, imaging sonar, optical inspection and environmental sensing. Combined with Kraken’s synthetic aperture sonar, subsea batteries, towed platforms and survey services, this creates one of the strongest independent technology portfolios in the maritime market.

The industry has spent decades buying platforms, sensors and software from different suppliers, then paying someone else to make everything communicate. We politely call this systems integration. Customers often call it something less printable.

Kraken wants to reduce that integration burden by controlling more of the subsea technology stack. The opportunity is substantial. So is the risk.

Two Histories, One Direction

Kraken was founded in Newfoundland in 2012 and built its reputation around compact synthetic aperture sonar, including AquaPix SAS, the KATFISH towed system and SeaPower pressure-tolerant batteries.

Covelya has a much longer history. Its roots reach back to Sonardyne, founded in 1971. Sonardyne became a leading supplier of underwater acoustic positioning, navigation and communications. The wider Covelya group later brought together EIVA, Chelsea Technologies, Wavefront Systems, Voyis and defence integrator Forcys.

Kraken announced the acquisition in March 2026 and completed it on July 2 for approximately C$615 million, including C$480 million in cash and C$135 million in shares.

That is a serious cheque. But Kraken was not buying revenue alone. It was buying the missing pieces of a much larger system.

Building the Subsea Stack

Kraken already had powerful underwater eyes and a large battery.

Covelya adds much of the nervous system.

Sonardyne brings navigation, positioning and communications. EIVA contributes NaviSuite software for mission planning, survey acquisition and data processing. Wavefront adds Solstice side-scan sonar, Vigilant forward-looking sonar and Sentinel intruder detection sonar. Voyis provides optical imaging and laser scanning. Chelsea contributes environmental sensors, while Forcys packages these capabilities for defense customers.

Now combine SeaPower batteries, Sonardyne navigation, Kraken SAS, Wavefront sonar and EIVA software inside one autonomous underwater vehicle.

That could reduce interface risk, shorten integration schedules and simplify support. It also allows products to be developed together rather than connected through a collection of cables, specifications and increasingly desperate engineering meetings.

The combined organization will have approximately 1,200 employees, more than 700 customers and over 110 issued or pending patents.

Kraken can now pursue larger integrated programs in mine countermeasures, seabed warfare, offshore inspection, critical underwater infrastructure protection and persistent ocean monitoring.

How Will It Be Structured?

Kraken Group will focus on corporate and financial governance. Kraken Robotics will operate the products, technologies, systems, services and commercial activities.

Greg Reid remains CEO, with Bernard Mills serving as President. Several former Covelya executives will lead technology, products and enterprise performance.

The structure is logical. The challenge will be preserving the specialist cultures and customer relationships within Sonardyne, EIVA, Wavefront and the other businesses.

Buying excellent companies is easier than integrating excellent engineers.

Final Ping

Customers should benefit from fewer interfaces, broader support and lower integration risk. But vertical integration can also create dependency.

When one supplier provides the battery, navigation, sonar, communications and software, replacing one component may become difficult. The integration tax may fall, while the cost of supplier lock-in rises.

The real question is whether customers should embrace the complete stack or preserve room for alternative sensors, software and future upgrades.

What do you think? Does this acquisition simplify subsea operations, or concentrate too much capability under one roof?

At Strategic Sonar Solutions, I help clients assess sonar payloads, autonomous platforms, and system architectures before expensive choices become permanent. Sometimes full integration is the right answer. Sometimes independence is the more valuable capability.
