Think of the Chesapeake Bay as the Indianapolis Brickyard for submarines.
Defense contractor Northrop Grumman is conducting initial research at its facility near Annapolis to develop submarines capable of doing 100 knots - 115 miles per hour - underwater for 10 minutes at a stretch.
The company won a contract that could be worth nearly $46 million from the Defense Advanced Research Projects Agency to study the feasibility of supercavitation technology. In conjunction with Pennsylvania State University's Applied Research Laboratory, Northrop Grumman will do part of the research at its undersea systems facility near the Bay Bridge.
If successful, the technology could create a new generation of superfast submarines to transport personnel or equipment. Supercavitation creates a pocket of gas around a submerged vehicle, greatly decreasing drag from friction. Water resistance is 1,000 times greater than wind resistance.
