Tango Bravo R&D Project to Drive Down Sub Size

The Navy and the Defense Advanced Research Projects Agency (DARPA) plan to pour $97 million between 2004-2009 into a new joint project known as Tango Bravo, intended to lead to the design of a new attack submarine that would have all the capabilities of the current Virginia Class boats, but at half the size and half the build cost. As a comparison, SSN-774 Virginia Class attack submarines are 377 feet in length, and have a 34-foot beam. They cost approximately $2.0-2.5 billion each.

Tango Bravo grew out of a joint Navy-DARPA study that was finished in May 2004, which looked at a number of factors that affect the size and cost of hull, mechanical and electrical systems on a submarine. Led by Naval Sea Systems Command's Program Executive Officer for Submarines, the Tango Bravo project is a demonstration project aimed at bringing fundamental change to future U.S. submarines while maintaining or improving their current capabilities.
