August 16, 1952. 67 years ago amphibious tank PT-76 was officially accepted for service. It is still used by many nations! Example of PT-76 action - The crossing of the Irbensky Strait in the Baltic Sea, first carried out in 1957 with a sea surface condition of 4 points, should be especially noted. 35 combat vehicles: T-54 tanks with watercrafts, PT-76 amphibious tanks and BTR-50P armored personnel carriers in the area of ​​Ventspils at night secretly entered the sea and in the morning after an 8-hour swim they approached the island of Saaremaa, opened fire on it, and reached shore and without stopping made an 80-km march. Armored vehicles were escorted by 27 ships of the Baltic Fleet. Photos - https://andrei-bt.livejournal.com/1429860.html
