Hyliion USX-1 Defiant USV Chosen as Launch Platform for KARNO Core Sea Trials
Hyliion Holdings Corp., a developer of modular power plant technology, announced that the U.S. Navy’s Office of Naval Research (ONR), in partnership with the Defense Advanced Research Projects Agency (DARPA), has selected the USX-1 Defiant as a candidate test vessel for Hyliion’s KARNO technology. Initial sea trials are funded under a development program from the Office of Naval Research (ONR) to advance the use of KARNO Cores for onboard power generation in U.S. Navy vessels.For the USX-1 Defiant sea trials, Hyliion will deliver a drop-in 800 KW power system consisting of four 200 KW
Underwater 3D Printing of Concrete Ready for DARPA Assessment
have a remotely operated underwater vehicle that shows up on site with minimal disturbance to the ocean, then there is a way to build smarter and not continue the same practices that we do on the land.”The project got its start in fall 2024, when the Department of Defense’s Defense Advanced Research Projects Agency (DARPA) issued a call for proposals to design 3D-printable concrete that could be deposited at a depth of several meters underwater – and to do so in a radically truncated timeframe of one year.“When the call for proposals came out, we said, ‘Hey, let’s just
Manta Ray UUV Prototype Completes In-water Testing
The Manta Ray prototype uncrewed underwater vehicle (UUV) built by Northrop Grumman completed full-scale, in-water testing off the coast of Southern California in February and March 2024. Manta Ray was built through a Defense Advanced Research Projects Agency (DARPA) program aimed at advancing key technologies to benefit future UUV designs, including techniques to manage energy, increased payload capacity, low-power propulsion and more.The recent in-water testing demonstrated at-sea hydrodynamic performance, including submerged operations using all the vehicle’s modes of propulsion and

through a secure channel. During the two days of testing, the team was able to collect the data needed to move their project forward.“The results were fantastic,” Demirors said. “Everything was functioning as it should be.”The HydroNet project is funded by the Defense Advanced Research Projects Agency (DARPA) through the Small Business Innovation Research (SBIR) and Small Business Technology Transfer programs, which encourage small businesses to engage in government research and development with the potential for commercialization.“We are extremely pleased about this partnership
DARPA Funds Tech to better Detect Whales
Charles River Analytics won a $1.5 million follow-on contract from the Defense Advanced Research Projects Agency (DARPA) to develop a multi-sensor fusion module that incorporates deep learning to autonomously and accurately detect whales and other aquatic mammals.To protect marine mammals from collisions and sonar exposure, sailors must keep a vigilant lookout. Operators of remotely operated vehicles must also stay alert, and uncrewed surface vehicles’ (USVs) currently limited and narrow video feeds create risk, too. To reduce the strain on human lookouts, and give USVs the ability to steer clear
Sonardyne Suite for Dive Technologies’ AUV
Technologies of Quincy, Mass., selected a suite of Sonardyne technologies for navigation, tracking and control of its large displacement DIVE-LD autonomous underwater vehicle (AUV) program.Founded in 2018, Dive Technologies’ rapid development program has included support from the Defense Advanced Research Projects Agency (DARPA) and technology partnerships with organizations including the Center for Marine Autonomy and Robotics at Virginia Tech. A key part of the development has been to opt for high-performance, off-the-shelf systems for its DIVE-LD AUV, a 19-ft. long, 48-in. diameter vehicle designed
Xerox and DARPA Partner to Develop IoT Ocean Sensors
PARC, a Xerox company, announced Thursday it has been awarded a contract by the U.S.' Defense Advanced Research Projects Agency (DARPA) for the next development phase in the Ocean of Things, a project to expand what scientists know about the seas.Initially announced by DARPA in 2017, the Ocean of Things project is deploying small, low-cost drifters in the Southern California Bight and Gulf of Mexico to collect data on the environment and human impact. This includes sea surface temperature, sea state, surface activities and even information on marine life moving through the area.“Oceans cover
Gibbs & Cox to Develop 'Sea Train' Concept
Naval architecture firm Gibbs & Cox said it has been awarded a multi-phase contract from the U.S.' Defense Advanced Research Projects Agency (DARPA) to develop and demonstrate a connectorless "Sea Train" concept.DARPA's Sea Train program aims to demonstrate long range deployment capabilities for a distributed fleet of tactical unmanned surface vessels. The program seeks to enable extended transoceanic transit and long-range naval operations by exploiting the efficiencies of a system of connected vessels.The goal is to develop and demonstrate approaches that exploit wave-making
Anti-Submarine Warfare: Unmanned Future
or standalone capability for ASW is just beginning to emerge. One example is the ACTUV, a 40-meter long-endurance unmanned ASW platform being developed by DARPA and ONR in the U.S.” The ASW Continuous Trail Unmanned Vessel (ACTUV) is an unmanned vessel designed by the Defense Advanced Research Projects Agency (DARPA). The state-of-the-art vessel is built specifically to track quiet diesel-electric submarines, at a fraction of their size and cost. The project also seeks to advance unmanned system autonomy so that maritime operators are able to deploy platforms capable of crossing
