Submarine Day on April 11 honors a momentous occasion in American history. In 1896, Irish-American John Phillip Holland invented and launched The Holland VI submarine from Crescent Shipyard in Elizabeth, NJ. It became America's first commissioned modern submersible vessel, and by 1900, it was inducted into the U.S. Naval Service.

National Submarine Day celebrates America's naval heritage that dates back centuries. David Bushnell built America's first submarine, the Turtle, during the Revolutionary War. However, as the U.S. Navy did not exist yet, the first U.S. Navy submarine was not the Turtle but the USS Alligator, active during the American Civil War. The rest of the world celebrates Submarine Day on March 17 each year.

How to Celebrate Submarine Day

There are plenty of fun ways to celebrate this momentous day. Eat as many sub sandwiches as you can, for starters! If you have kids, why not download a submarine coloring sheet for them? You could also get some friends together and watch a classic submarine movie such as The Hunt for Red October, U-571, and Das Boot. Or, you could take a submarine tour if you live near a museum. Don't forget to share your photos with the hashtag #SubmarineDay
