Almost exactly 50 years ago, the USS Scorpion became the last U.S. submarine to be lost at sea when it disappeared while on patrol in the North Atlantic in 1968, with the nearly 100 officers and crew lost and presumed killed.

This weekend, those who went down with the Scorpion—and nearly 4,000 others lost in dozens of U.S. submarines that have sunk or gone missing since 1900—will be honored.
