Underwater Swimming Pool
The Soviet Union was a formidable force for many decades. The world finally realized this fact when it came up with the world’s largest submarine in 1981. The submarine had a cache of close to 200 nuclear warheads, and a 120-man crew could stay on board for months at a time.
This photograph depicts the interior of one of the pressure hulls, which had a swimming pool for the crew, who were sometimes submerged for up to four months per deployment. We’re trying to imagine the interior of the submarine before it was decommissioned, back when it was in service, and we can see the crew chugging vodka while singing the national song.
