In 1939, the newly-built USS Squalus, a Sargo-class American diesel-electric submarine, sank during a test dive off of Portsmouth, New Hampshire. Â Due to a mechanical failure of an induction valve, the after torpedo room, crewâs quarters, and both engine rooms flooded, killing 24 sailors and two civilian technicians. Â The rest of the crew, 33 men, managed to seal internal watertight doors and hole up in the forward end of the vessel, which settled on the bottom in 243 ft/74 m of water.
The subâs forward end maintained its watertight integrity, so now the 33 survivors just faced the option of suffocating when they ran out of air to breathe.
And thatâs when a bad motherfucker named Charles âSwedeâ Momsen said âNot today.â Â After Squalusâ sister ship, the USS Sculpin, located the wreck, men on the two boats were able to communicate via underwater telephone. Â The survivors on the Squalus gave their numbers, condition, and amount of remaining breathable air. Â The Sculpin told them to sit tight and help would be on the way.
Momsen, who made a living out of spitting in Poseidonâs eye and then shitting in the sea godâs coffee cup, got to work with a new device called the McCann Rescue Chamber.  After two days of round-the clock effort, and some incredible work by Navy divers, all 33 survivors were rescued and brought to the surface.  Four enlisted divers--Chief Machinist's Mate William Badders, Chief Boatswain's Mate Orson L. Crandall, Chief Metalsmith James H. McDonald and Chief Torpedoman John Mihalowski--were each awarded  the Medal of Honor for their work in the cold waters during the rescue effort.
The usage of the McCann Rescue Chamber still marks the only time that people were successfully rescued from a sunken submarine.
The Squalusâ story was not yet over, though. Â Because the boat incorporated a number of new design features, Navy brass decided to raise the entire boat and re-commission it. Â Amazingly, they did just that; they salvaged the vessel, towed it back into the Portsmouth Navy Yard, completely refitted it, and re-commissioned it the USS Sailfish on May 15, 1940.
Shortly thereafter, as you may recall, the United States got involved in that whole Second World War thing that was all the rage at the time. Â And the Sailfish took part in said war. Â In fact, the boat made TWELVE successful war patrols in the Pacific Ocean. Â I suppose all of its bad luck had been used up already.
Think, for just a second, how gigantic and brass your balls have to be to go into an actual shooting war on a submarine. Â Then imagine doing that on one that had already sunk once. Â
During the war, the boatâs commanding officer issued a standing order that anyone on board who was heard saying the name âSqualusâ would be marooned at the next port of call. Â Because submarine sailors are a stubborn, insubordinate lot, they decided to refer to their boat as the Squailfish. Â Because some things just donât ever change.
After the war, the Sailfish was decommissioned and sold for scrap in 1948. Â But the boatâs conning tower (the part that sticks up above the main deck) was removed and placed at the Portsmouth Navy Yard to serve as a memorial to its lost crew from 1939 and as a reminder to the people who work there-civilian and military--that the stakes of their job are rather high. Â It remains there to this day.
