Sauro-class submarine equipment records. Variants, orders and quantities are shown as reported in each inventory source; coverage is incomplete.
Italian Navy Sauro-class submarines in the fleet during 2025. The command's annual review explicitly identifies four Sauro boats, separate from four U212A boats. This is fleet composition, not a simultaneous deployability count.
Reported count for Sauro class. Service scope: Italian Navy ships; does not replace a national total. 1 distinct quantity component(s) from the same source list; shared rowspan cells counted once. Explicit source inventory scope: active; no other stock status or total inferred. Count column(s): in service: 4. Origin: unstated. The listed variants/roles are the scope, not an immediately deployable count. The components do not establish one inventory census date; the stored date is the retrieved source snapshot.
