Navy exact named class holdings of Hai Lung. Active, operational-reserve and training units excluding equipment in store; November 2025 IISS assessment. Named service only, not a national or parent-force total or combat-readiness measure. Source role(s): SUBMARINES / SSK. No heading aggregate, carried armament, crew, payload, factory production or future order count inherited. The own fetched design source declares this exact class and its PDF operator country; ship capacities and fitted launcher/armament counts are retained as source scope, not added to hull quantities.
