Submariner's Day in Russia
March 19 · Level 9 · #402 of 2238

Russia's Submariner's Day honours the personnel and veterans of its submarine forces. It recognises a demanding kind of naval service, where technical skill, composure and trust among crewmates are essential.
How it is celebrated: naval units hold ceremonies and meetings with veterans. Colleagues and families congratulate submariners, and flowers are laid at monuments in remembrance of those who died in service.
The date looks back to 1906, when submarines became a distinct class of vessel in the Russian naval classification. That administrative change became a milestone in the history of the submarine service.
