March 19 is Submariner's Day in Russia!
On this day in 1906, Tsar Nicholas II included a new class of warships – submarines – in the classification of ships operated by the Russian Imperial Navy.
Submariner's Day was, however, not celebrated in the Soviet Union. It was only revived in 1996.
Traditionally, it is not only a holiday for sailors, but also for everyone who ensures the construction, repair and maintenance of combat readiness of the submarine fleet – designers, submarine builders and ship repairmen, to name a few.
