'In 2055 the experimental testbed DSRC-SN01 "Thresher" was launched using a ground breaking new atomic motor that was set to revolutionise Submarine design. Its sister craft, DSRC-SN02 was destroyed in an mysterious accident in dry dock. With the alarming growth of Bezernik power and the increasing number of mysterious disturbances at sea, the design was overhauled to a much faster more powerful craft, and work began on the DSRC-SN03 "Stingray".' ~Chrisofedf
