Business-class operations to 2000ft

ORCASUB is a two person, 2000-foot depth rated ‘flying’ submersible. Utilizing Nuytco's patented, welded steel pilot hulls allows for a more comfortable, “business class” cockpit for each pilot. ORCASUB also benefits by incorporating Nuytco's aluminum battery cylinders thereby allowing for a variety of battery types to be employed, which are easily hot-swappable in the field. Long range underwater communications, advanced sonar capability and a powerful lighting package are standard equipment on every ORCASUB. A training course for two pilots and one crew chief is included.
