Submarine Day
April 17, Thursday
History of the holiday
The date of April 17 was chosen in honor of the fact that on April 17, 1900, the first submarine was commissioned in the United States, which was included in the Navy. It was called USS Holland (SS-1) and became the first military submarine in the history of the United States. This moment marked the beginning of the development of underwater technologies that would play a key role in global military conflicts in the 20th and 21st centuries.
