US Navy Cruiser and Submarine Collide

An anonymous reader writes "Despite billions of dollars in advanced electronics, radar, and sonar it seems the Navy needs to install backup cameras on their boats. 'The Pentagon said late Saturday that it is investigating why a Navy submarine collided with an Aegis cruiser during routine operations at an undisclosed location.' According to ABC, 'the two ships were participating in a “group sail” along with another vessel. The three ships were participating in an anti-submarine exercise in preparation for an upcoming deployment as part of the strike group for the aircraft carrier USS Harry S Truman."
