VESSEL REVIEW | Matilda 1 – New stern landing vessel boasts long-distance navigation capability

By incorporating a hybrid nuclear-ready capability, vessels can gain effectively unlimited operational range, significantly reduced reliance on conventional fuels, and extended endurance for sustained missions.

Seatransport said this approach will also enhance operational flexibility, deliver low-emission performance, and enable reliable operation in demanding environments, such as landing and logistic support on unprepared or remote beaches.

The MMRs under consideration range from 1.2 MW to 2.6 MW and are undergoing technical and regulatory assessment.

“These designs secured an approval in principle from Lloyd’s Register in February 2026 for the inclusion of MMRs into a hybrid design that can operate with either diesel generators or the nuclear MMR,” Ballantyne told Baird Maritime. “The first live test of an MMR-propelled SLV is programmed for November and December 2027.”
