Launched in 1960, the USS Tullibee was a one-off design fast attack nuclear submarine (SSN).
Some of the unique features of this boat include its "humped back," making it look similar to a ballistic missile submarine, as well as its pair of antennae mounted on the sail (good luck printing those). Tullibee also had the distinction of being the smallest nuclear submarine ever built by the United States Navy.
