IDEF 2021, Turkey’s largest defense exhibition, featured a variety of submarine designs and concepts. STM, a Turkish defense engineering company, unveiled the STM500 small submarine just a few days before the show, and it also displayed the TS1700, a 1700-ton submarine. Dearsan, a Turkish shipbuilder that recently completed the delivery of a brand-new corvette to Turkmenistan, has unveiled a concept design for a light submarine.
