Fairbanks Morse Defense unveiled AutoHook, a fully autonomous interface for recovering unmanned surface vessels, at EURONAVAL 2026 in Paris, the naval defense exhibition running November 3-6. Built by the company's Norwegian subsidiary Vestdavit, the system is rated to operate at Sea State 4, roughly double the rough-water limit of existing autonomous recovery equipment, according to Ocean News.
What problem does AutoHook solve?
Navies are adding unmanned surface vessels, or USVs, for scouting, mine-hunting and logistics faster than they have solved a basic mechanical problem: getting those boats safely on and off a host ship. Today that usually means a sailor on deck physically hooking a line to a moving, bobbing craft, a task that becomes dangerous once waves pick up and is often called off above Sea State 2, roughly 1 to 3 feet of wave height.
AutoHook removes the sailor from that connection entirely. Vestdavit says the system has achieved operational acceptance at Sea State 4, conditions with waves up to roughly 6 to 8 feet, a threshold the company frames as the one most existing autonomous launch-and-recovery gear cannot clear.
How does the system work?
AutoHook is built as a compact, clamp-on unit that combines integrated thrusters, onboard power and an AI-driven vision system in a single housing attached to an existing davit wire. The vision system tracks the target vessel's position in real time and uses the thrusters to maintain a stable connection point even as both the host ship and the USV move independently in the swell.
Vestdavit CEO Rolf Andreas Wigand said the system "breaks the Sea State 2 ceiling that has long constrained manual launch and recovery," framing the advance less as a speed improvement and more as an expansion of the weather window in which recovery is possible at all.
Who would use it, and why does Sea State 4 matter?
Fairbanks Morse Defense's existing customer base includes the U.S. Navy, U.S. Coast Guard, Military Sealift Command and Canadian Coast Guard, all of which already operate Vestdavit davit systems and are candidates to retrofit AutoHook without replacing existing shipboard equipment. The company says the unit installs on current davit wire systems without new winches or structural modifications, which matters for fleets looking to add autonomy without a lengthy refit.
Sea State 4 is a meaningful threshold because it covers a large share of open-ocean conditions navies actually operate in, rather than the calm-water scenarios where most autonomous recovery demonstrations have taken place to date. A system limited to Sea State 2 is unusable on many operational days; one rated for Sea State 4 is not.
What's next?
Fairbanks Morse Defense is demonstrating AutoHook to attendees at EURONAVAL through November 6, where NATO interoperability is a recurring theme given the alliance's push toward standardized unmanned systems across member navies. The company has positioned the product's NATO-aligned design as a selling point for allied fleets looking to field USVs without each navy developing its own recovery hardware.
No contracts or formal acquisition programs have been announced alongside the unveiling. The next milestone to watch is whether any of Fairbanks Morse Defense's existing Navy or Coast Guard customers move AutoHook from demonstration to shipboard trials.
