Just 3 more Shark class frigates will be built by the HCS this year before production switches to an upgraded version of Shark. This is known as Shark 2.0 though it is thought the final name will be the Thresher class frigate.
Shark was intended to replace the rapidly aging and obsolete Kalahati Tuul-B and Kalahati Tuul 2 fleets and thus the HCS had to compromise on some details to "get it out of the door". With the immediate need now satisfied the HCS are looking for a ship to replace it's Kalahati Tuul-S fleet and some early Cosmoses. The ship will have a longer range than Shark 1.0 and will also be slightly bigger, in many ways Thresher will be to Shark what the Berlin class will be to Rome. A larger enhanced version of an already pretty decent platform.
Its not known if the HCS will be following the DDS down the modular mission role but Thresher will have extra space for "mission specific equipment". The first Thresher is expected next year.
