Aquanaut® 2.1
An improved commercial configuration of the Aquanaut® Mk2 platform. Aquanaut® 2.1 is an all-electric, untethered subsea vehicle built for autonomous transit, survey, and inspection, with cable and pipeline following targeted for the 2.1 delivery program. Build slots are available now for configurable customer requirements up to a 3,000 m design rating.
Same Aquanaut® Mk2 foundation, improved for manufacture and customer delivery.
Aquanaut® 2.1 is the improved commercial configuration of the field-tested Aquanaut® Mk2 platform. It keeps the all-electric, untethered architecture and Nauticus ToolKITT™-native autonomy, the same footprint and capability, but with commercially hardened autonomous transit, survey, and inspection work at depth. Cable and pipeline following is targeted for the 2.1 delivery program. Bespoke missions and workflows are available for custom development.
Aquanaut® 2.1 can be designed to meet different depth requirements, up to a 3,000 m design rating, for customers who need deepwater data, inspection, and route-following capability without building the full operating stack themselves. The vehicle is designed for autonomous manipulation and control through a future update, working with Nauticus manipulators.
Aquanaut® 2.1 specification
Final customer configuration depends on selected depth rating, battery fit, payload package, and mission profile. Depth figures are design ratings; the Aquanaut® Mk2 platform has demonstrated operating depth of 2,300 m.
