  • What We Do

    Recovery of items and loved ones at depths beyond most diver's abilities, a platform for commercial film or video, research vessel for observation or experimentation, static displays for education; our submarine is highly portable with safety as a primary concern.

    Captain Brian

    Certified diver at the age of 14, built his own surface supplied diving gear a year later, dabbled in DIY mixed-gas rebreathers and put himself through college as a diver, Captain Brian also has 40 years experience working around and diving K boat submarines.


    A BioChemist before entering seminary, he recently retired after 35 years as an ordained Lutheran pastor. He holds a doctorate in family systems and is experienced in walking with grieving families.


    If your need should require additional submarine support, we routinely partner with Chesapeake Submarine Services.

    Innerspace Science is an organization that facilitates the use of privately owned submersibles for scientific and educational purposes on a non-commercial basis. Tehom Submersibles is a founding member and available to work with Universities, Research Stations and other organizations.
