This time in Submarine History

17 January 1955

The USS Nautilus transmitted a historic message: "Underway on nuclear power." As the world's first nuclear-powered submarine, Nautilus could remain submerged for two weeks at a time and travel at speeds of over 20 knots, or about 23 miles per hour. The Nautilus is now part of the Submarine Force Museum in Groton, Connecticut.

NSL Highlight: USS Scranton Holds Change of Command Ceremony


The Los Angeles-class fast-attack submarine USS Scranton (SSN 756) held a change of command ceremony onboard Naval Base Point Loma, San Diego, Calif., June 20, 2025.
Cmdr. Anthony Ardito relieved Cmdr. Jeff Ransom as the Scranton’s commanding officer during the ceremony.

Cmdr. Anthony Ardito most recently served at United States Strategic Command and was the executive officer of USS Kentucky (GOLD) (SSBN 737) prior to that. He also served aboard Los Angeles-class submarines USS Columbus (SSN 762) and USS Annapolis (SSN 760).

“I am honored to join the ranks of the iron horse,” said Ardito. “Scranton is the premiere fighting force of the fleet, ready and capable because of the iron men that bring the ship to life.”
