America’s maritime strength depends on the ships we build, the infrastructure we protect, and the people who turn emerging technology into operational capability.

Six Maritime CEO Joseph Allen will attend the Ironclad Maritime Summit on October 27 in Norfolk, Virginia, connecting with leaders working to strengthen the nation’s maritime industrial base.

For Six Maritime, that conversation starts at the waterfront.

Protecting shipyards, ports, and high-value vessels is essential to sustaining maritime readiness. Integrating unmanned systems into those environments requires experienced operators, practical training, and an understanding of how maritime missions work every day.

That is the perspective we bring: years of waterborne security and maritime training experience, paired with hands-on support for autonomous systems testing and integration. Our focus is on connecting human expertise with emerging technology to meet real operational needs.

Joe looks forward to connecting with shipbuilders, defense technology developers, and government partners to discuss:
• Protecting the waterfront infrastructure that supports fleet readiness.
• Integrating manned and unmanned capabilities into maritime security.
• Providing the operators, training, and on-water support needed to move technology into service.

Preparing for the future of maritime security takes both practical experience on the water and continued engagement with the people shaping the discussion.

Six Maritime’s Joe Allen and Hank Kim recently joined Matt Classen, Director of TMA BlueTech, for remarks by retired Admiral Lee Hsi-Min of Taiwan.

Gatherings like this provide an opportunity to hear different perspectives, strengthen relationships across the maritime community, and consider how emerging technologies can meet operational needs.

At Six Maritime, those considerations connect directly to our work: bringing maritime operators, technology providers, and mission requirements together. Our experience in waterborne security, small-boat training, and unmanned systems support informs how we approach that integration and the questions we bring to discussions about maritime defense.

As we prepare for our DIU REEF demonstration in November, we continue to value opportunities to exchange ideas with leaders across government and industry. Those conversations complement the hands-on preparation underway within our team.

Thank you to TMA BlueTech for helping connect the maritime community and advance these discussions.

Six Maritime has been selected to participate in LANTERNFISH 2027.

This opportunity advances a central focus of our work: connecting emerging maritime technologies with the operators, procedures, and operational experience needed to make them useful in the field.

Protecting ports, harbors, naval assets, and critical maritime infrastructure requires more than individual sensors or unmanned platforms. It requires a coordinated approach that connects detection, situational awareness, command-and-control, and operator-directed response.

Six Maritime brings more than a decade of maritime security experience to that challenge. Our role as an operational integrator starts with the mission: understanding what crews and commanders need, bringing complementary capabilities together, and developing practical ways to employ them.

We look forward to working with the LANTERNFISH team and fellow participants to demonstrate our approach, learn from mission-relevant assessment, and refine how integrated capabilities can support maritime defense.

Thank you to our team and technology partners for the work that brought us to this milestone.

Operational readiness starts with hands-on experience.

Six Maritime Training Manager Robert Macejak recently attended a UUV Operators Course in Rhode Island, training with a VATN unmanned underwater vehicle in preparation for our DIU REEF demonstration this November.

These photos capture Robert handling the UUV aboard a small boat and deploying it into the water, the practical work behind preparing an unfamiliar system for use on the water.

For Six Maritime, operator training is an essential part of maritime technology integration. Understanding the equipment, developing proficiency, and connecting that experience to operational planning all contribute to a better-prepared demonstration team.

As we prepare to demonstrate our Counter-Unmanned Underwater Vehicle system-of-systems concept, this training helps build our team’s familiarity with the underwater platforms involved and supports the preparation needed to conduct the demonstration safely and effectively.

Robert brings that experience back to his role as our training manager, strengthening the connection between new technology and the people who will operate alongside it.

More to come as we prepare for November.

Six Maritime is proud to announce that after the competitive Commercial Solutions Opening (CSO) down select process, the Department of War Innovation Unit (DIU) Robotic Exclusion & Engagement Framework (REEF) selection committee awarded Six Maritime a contract to conduct an initial baseline assessment for a Counter-Unmanned Underwater Vehicle (C-UUV) system-of-systems concept for maritime defense.

DIU accelerates the adoption of commercial technology to address high-priority national-security challenges. REEF addresses a growing maritime-security problem: protecting ports, harbors, critical waterways, and expeditionary forces from unmanned and autonomous underwater threats.

Six Maritime’s concept integrates distributed underwater detection and classification, resilient command-and-control, manned and unmanned maritime platforms, and operator-directed response options. The objective is a practical Detect–Track–Classify–Defeat framework that gives maritime-security forces a clearer operating picture, earlier warning, and more options to respond.

As the prime operational integrator, Six Maritime looks forward to demonstrating this operator-centered approach with our technology partners and the U.S. Government.

Six Maritime is looking to connect with a very specific type of maritime professional for an upcoming overseas assignment in the United Arab Emirates.

We are seeking experienced Small Boat Captains who bring more to the table than vessel operation alone. The ideal candidates will also have a strong mechanical background and be comfortable troubleshooting, maintaining, and supporting small boat systems in the field.

This is a niche requirement and reflects the type of operational support Six Maritime is increasingly being asked to provide: experienced mariners who can operate independently, solve problems, maintain equipment, and support demanding maritime programs wherever the mission takes them.

Anticipated requirements include:

• Significant small boat operating experience
• Strong small boat maintenance / engineering background
• Ability to diagnose and address mechanical issues in the field
• Current or active SECRET security clearance
• Ability to deploy internationally for approximately 110 days
• Professionalism and the ability to operate with limited supervision in an overseas environment
The current requirement is expected to involve a two-captain team supporting maritime operations in the UAE, with Six Maritime also providing the vessel supporting the effort.

We already have several strong candidates under consideration, but given how specialized this combination of qualifications is, and as our overseas maritime support continues to expand, we would like to identify additional qualified professionals interested in this type of work.

If your background sits at the intersection of small boat operations and marine engineering/maintenance, we would like to hear from you.

Please reach out via email at [email protected].

A successful exercise doesn’t end with the final underway evolution.

Following the completion of Bayonet Quest 26, our Six Maritime crew transited the Mk VI to Saint Ignace, Michigan, for haul-out and winter storage. Yesterday’s transit marked the next step in caring for the vessel after supporting a demanding training period.

We shared some of the underway highlights yesterday, from operating alongside USVs to supporting UAV operations. This photo captures another essential part of that work: bringing the boat home, recovering it, and preparing it for the off-season.

Effective maritime support requires attention across the full operation, from preparation and crew coordination through ex*****on, transit, and recovery. The work after the exercise deserves the same professionalism as the work underway.

Thank you to Captain Don and the crew for a successful Bayonet Quest 26 and for seeing the job through to its final stages.

Wrapping up Bayonet Quest ’26 with a look at Six Maritime’s crew in action aboard the Mk VI in support of the Michigan Air National Guard.

With Captain Don back at the helm and a new crew aboard, our team supported operations alongside unmanned surface vessels and UAVs. This video captures a few highlights: leading a USV formation, green-smoke signaling to a UAV, and recovering a UAV on the fantail while underway.

Behind those moments are the vessel preparation, seamanship, and coordination that keep operations moving. We’re proud to bring that experience to the integration of crewed vessels and unmanned systems.

Thank you to Don and the crew for their work throughout Bayonet Quest and to Don for capturing this footage from the water.

Protecting maritime installations requires understanding what is happening below the surface, and being prepared to act.

Six Maritime was selected as a TechConnect Critical Technology Spotlights finalist for our Counter UUV Base Defense solution. Hank Kim, our Vice President of Growth, Strategy & Partnerships, represented Six Maritime and presented the approach at the Defense TechConnect Innovation Summit & Expo in National Harbor, Maryland.

Our approach addresses threats from unmanned undersea vehicles through an integrated base defense solution that brings together passive and active acoustic detection, correlation with vessel and surface activity data, tracking, and response options.

The operational challenge extends beyond detecting an underwater contact. Defenders need to understand what that contact means, maintain awareness as it moves, and coordinate an appropriate response. Connecting those functions is central to our approach.

Six Maritime brings an operator’s perspective to that challenge, drawing on our experience in waterborne security, small-boat operations, training, and unmanned systems integration. Our focus is on connecting emerging technology with the people, procedures, and operational requirements that make it useful in the field.

TechConnect’s Critical Technology Spotlights connect innovators with government, industry, and investment partners around technologies aligned with national priorities. We appreciate the opportunity to contribute to that conversation and engage with others working to strengthen maritime defense.

Interested in collaborating on counter-UUV capabilities, maritime security, or operational integration? Let’s connect.

Today’s reported engagement of an explosive-laden unmanned surface vessel near Romania’s Neptun Deep gas project is another indication of how quickly the security environment around ports, offshore energy facilities, and other critical maritime infrastructure is changing.

According to current reporting, two Romanian F-16s responded after the USV was discovered approximately 80 nautical miles east of Constanța. One aircraft engaged it with its onboard cannon, damaging the vessel. Romanian maritime forces subsequently completed the response and rendered it safe. The drone’s origin has not been conclusively established.

Romania has already begun investing in persistent maritime surveillance. Following an earlier USV incident near Constanța, Romanian authorities reportedly acquired two Ocean Aero Triton autonomous underwater and surface vehicles. These platforms can remain on station for extended periods while collecting information above and below the water.

That is a smart step, but the platform itself is only one part of the solution.

Effective counter-USV and counter-UUV defense requires a layered system that can detect, track, classify, and respond to a contact before it reaches the asset being protected. It also requires trained operators who can interpret sensor data, maintain positive human control, coordinate with security and law-enforcement authorities, and select a response proportionate to the threat.

A fighter aircraft can respond quickly, but it should not have to be the routine answer to a relatively inexpensive maritime drone. Persistent autonomous surveillance, a shared operating picture, trained watchstanders, and manned or unmanned response vessels can provide an earlier and more sustainable layer of protection, while preserving high-end military assets for the threats that truly require them.

That is the operating concept behind Six Maritime’s Base Defense Security Unit: a vendor-neutral, man-in-the-loop capability that integrates the best available sensors and autonomous systems with experienced maritime operators, maintainers, and response crews.

The technology already exists. The real challenge is integrating it into an operational system that can protect critical infrastructure every day, not simply demonstrating another platform.

Romania, if you’re listening, we may know some people.
