The Durjeya class submarines are new ocean-going boats with substantially improved machinery and battery capacity, enabling longer and faster time spent underway. In conjunction with the Ninjatousaya, this should allow the boat to minimize time spent on the surface.
Armament has been revised somewhat over the previous Prakopa class, with the stern tubes and the major calibre gun being discarded. The latter is omitted in part for streamlining but also because the BNS is less concerned with conducting "Cruiser rules" trade warfare and more interested in hunting surface warships. Whether this proves to be a reasonable expectation remains to be seen.
A total of twelve boats are planned in 1945 and 1946, with the expectation that the six Satarka and Parangata class boats will be removed from active service at that time.
