History of National Submarine Day and How to Celebrate/ Observe It
National Submarine Day is celebrated on April 11th in honor of the submarine force and its history. This day commemorates the sinking of the USS Thresher (SSN-593), which occurred on April 10, 1963. The Thresher was the first nuclear submarine to be lost at sea, and the tragedy claimed the lives of all 129 crew members. The loss of the Thresher was a devastating blow to the submarine community, and served as a reminder of the dangers of submarine warfare.
In the years since the Thresher disaster, the submarine force has worked diligently to improve safety and prevent such tragedies from happening again. Today, the submarine force is one of the most technologically advanced and safe organizations in the world. On National Submarine Day, we remember those who have made the ultimate sacrifice in service of their country, and we honor the men and women who continue to serve in the submarine force today.
