Development
After completing the Hai class submarines, LTN felt that the fleet needed submarines with far greater capability and range. Therefore the follow-on class was intended to be larger, 400t design with improved seaworthiness. In all respect, the emerging Ahven was the first true combat capable submarine in TTPL service.
