I never knew that. Any idea why they picked April 11th? Was this the day that they commissioned the Holland Sub?
On April 11, 1900, the U.S. Navy acquired its first submarine, a 53-foot craft designed by Irish immigrant John P. Holland. Propelled by gasoline while on the surface and by electricity when submerged, the Holland served as a blueprint for modern submarine design. By the eve of World War I, Holland and Holland-inspired vessels were a part of large naval fleets throughout the world.
Don't worry, I didn't know about this day either until a couple of months ago
