The United States of America celebrates National Submarine Day on April 11, annually.
National Submarine Day is celebrated by civilian Americans and Naval units. However, various other nations have their submarine force to pay respect to, so they all celebrate National Submarine Day as well, but on different dates.
National Submarine Day was started in 1970 by a bill introduced in the US Senate.
Senator Thomas J. Dodd proposed the bill to celebrate April 11 as National Submarine Day, which the US Senate later passed.
National Submarine Day celebrates the United States Navy, especially the acquisition of the modern submarine Holland VI on April 11. Still, the day had to go through a long journey to reach and claim a special appreciation day for submarines. The creation, launch, and celebration all went through an extended period, which was significant in celebrating National Submarine Day and its history. Holland VI marked a substantial contribution to the future production and improvement of better submarines and warships. So, let's learn more about its journey here.
Navy museums and US submarines visitors rise on National Submarine Day as people from all over the region visit to get a glance at history.
You can enjoy National Submarine Day by visiting a Navy museum to get a closer look at submarines, their workings, and the history of how this modern marvel offered us what seemed impossible in the past. If you don't have access to a Navy museum, you can go to the sea and have fun with your friends. A boat ride can be all you need for a fun day at sea!
The first submarine, created by Mathematician William Bourne, had a weatherproof leather jacket.
The submarine concept came out of ancient fascination, recorded by famous people like Aristotle and Alexander the Great to make a man work underwater.
The first military submarine was built in 1776, called Turtle.
Submarines were widely used during World War I and World War II.
National Submarine Day commemorates the USA receiving the first modern commissioned submarine, USS Holland.
Submarine Day is primarily celebrated in the USA; however, it is a national festival that various nations observe for their naval achievements on various dates.
