France’s Rubis class nuclear-powered attack submarine Perle has finally returned to active service after nearly four years. Perle had begun undergoing a routine maintenance and refit cycle in 2019, but then suffered a devastating fire in 2020 that required extensive repairs. This included grafting on a ‘new’ front half taken from a decommissioned Rubis class submarine, the ex-Saphir. The result is a unique submarine that is slightly longer than a standard Rubis.
