Rubis-class submarine equipment records. Variants, orders and quantities are shown as reported in each inventory source; coverage is incomplete.
FranceNavy exact named class holdings of Rubis. 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 / SSN. No heading aggregate, carried armament, crew, payload, factory production or future order count inherited. Family total is the sum of the separately printed nonoverlapping exact model components, each explicitly declared by its own source; no parent or sibling variant identity inferred. 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.
