Northrop Grumman to Evaluate Supercavitation-Based Underwater Travel

A team led by Northrop Grumman Corporation has won a $5.4 million contract from the Defense Advanced Research Projects Agency (DARPA) to determine the feasibility of using supercavitation technology for stable, controllable, high-speed underwater transport. The Underwater Express program is a DARPA technology research and evaluation program to establish the potential of a new technology. Supercavitation creates a gas cavity between the vehicle surface and the water, thereby reducing drag and increasing vehicle speed. The program's ultimate goal is a new class of underwater craft for littoral missions that can transport small groups of Navy personnel or specialized military cargo at speeds up to 100 knots.
