CLAQ CleanTech Acquisition Corporation

Nauticus Robotics, Inc. ("Nauticus"), a Houston-area developer of surface and subsea robots, autonomy cloud software, and associated services, has been awarded an Other Transaction Agreement by the U.S. Defense Innovation Unit (DIU) to prototype its autonomous command and control software platform, ToolKITT, aboard the U.S. Navy’s VideoRay Mission Specialist Defender Remote Operated Vehicle. DIU is a Department of Defense organization that contracts with commercial companies to solve national security problems.

Through internal investments and advancements sponsored by commercial and government customers, Nauticus has developed ToolKITT, a unified software platform utilizing advances in autonomous behaviors to identify, classify, and perform complex underwater activities which helps to remove warfighters from harm’s way. ToolKITT was specifically designed for ease of integration to enable autonomy across multiple robotics platforms and is also used in Nauticus’ flagship product, Aquanaut.

“We are committed to offering the best in maritime robotics and autonomy and are pleased DIU and the U.S. Navy have recognized our efforts with this award,” said Todd Newell, Senior Vice President of Business Development at Nauticus. “We believe we have a disruptive technology platform within the ocean services market that can generate a reduction in required operations personnel and also both costs and carbon footprint for our customers.”

This competitively awarded Prototype OT has the potential of a follow-on production contract without further competition, in accordance with §10 U.S.C. 2371b(f), and upon a determination that the prototype project has successfully been completed.

On December 16, 2021, Nauticus Robotics and CleanTech Acquisition Corp. ("CLAQ") (NASDAQ: CLAQ), a special purpose acquisition company, entered into a definitive business combination agreement that would result in Nauticus Robotics becoming a public company.
