Indeed. My guess is that there will be a very intense demand from brother Turk states neighboring Caspian Sea to counter Iranian threat. At the same time, it will be a platform for states that cannot afford large-scale submarines or naval fleets would also like to have.
Previously, STM had signed a contract with Pakistan for development of a midget submarine. Presumably, Pakistan will be eager to replace their obsolete small submarines with STM500.
Apart from this, a small 33m submarine (STM500-42m) named LSUB-33, which is lighter than the STM500, was designed by the Dearsan shipyard. The LSUB33 has a speed of 10kts and a diving depth of 150m. This submarine can also be evaluated by the TN or export markets.
