Uss Blueback

The USS Blueback, which features such postwar technological design innovations as the teardrop hull and the use of a single propeller, was the last in a long line of non-nuclear submarines. Though all subs manufactured afterwards were powered by nuclear energy, the Blueback was by no means outdated, as she served her country for 31 years before being decommissioned. Notable achievements in the sub’s history include traveling 5,340 miles underwater from Yokosuka, Japan to San Diego, California, thereby setting a world record.
