New generation Navy attack sub to have torpedoes with 200-nautical-mile range

The U.S. Navy is starting early preparation work to design a new nuclear attack submarine to replace the Virginia-class boats (SSN-774) in the 2030s. The new attack SSN(X) boats would become operational in 2044 after the last Block VII Virginias are built.
Future Virginia boats and the SSN(X) can employ networked, extremely long-ranged weapons. A torpedo propulsion system concept from the Pennsylvania State University could allow a torpedo to hit a target 200 nmi (230 mi; 370 km) away and be guided by another asset during the terminal phase. Targeting information might also come from another platform like a patrol aircraft or an unmanned aerial vehicle (UAV) launched from the submarine.
