National Submarine Day
National Submarine Day is a holiday that’s observed on the 11th of April each year. It’s a day that commemorates the day when the U.S Navy acquired its first modern commissioned submarine in 1900. This submarine was called the Holland VI and it was invented by John Phillip Holland.
On April 11, 1900, the U.S government purchased this sub for $150,000-the equivalent of 4.8-million in 2021. This is a great day for people to learn more about submarines or for submarine fans to take the time out of their day to visit one of the many submarine exhibitions, exhibits, or memorials located all across the United States.
