For a period, Persia had more or less stopped making naval policy and acquisition decisions for itself - Bharat was calling the shots. With the change in government in both nations in 1941, Persia's senior officers have been quick to re-assert Persian interests as the driving force for naval construction and acquisitions.
One of the first steps was to cancel the purchase of seven G-135 class destroyers from Bharat. The ships were old, small, and under-armed compared to modern boats; worse, Persia had the capacity to build its own destroyers. This didn't come in time to prevent the transfer of the first two G-135s, but it does mean that they'll be the first to be replaced by the new Ayask class.
This class is intended to be a multi-purpose ship, with adequate speed, armament, and range. Considerable miscellaneous weight has been set aside for future sensor growth, as well as troop or mine-carrying capacity.
Persia has penciled in plans for four boats, built at a rate of one per year; the third and fourth boats may have newer engines and slightly different stats - check back in 1944 to see.
