[2] Original plans were for 17 FREMM hulls to replace the nine D'Estienne d'Orves-class avisos and nine anti-submarine (ASW) frigates of the Tourville and Georges Leygues classes.
Following the cancellation of the third and fourth of the Horizon-class frigates in 2005 on budget grounds, requirements for an air-defence derivative of the FREMM called FREDA were placed – with DCNS coming up with several proposals.
[4] In 2015, the total number of ASW variants was further reduced to just six units, including Bretagne.
This provides both ships with a potentially enhanced area air defence capability, though both vessels still lacked the boosted variant of the Herakles multi-function radar (which was necessary to accommodate the full range of Aster 30) as well as a complementary fire control radar.
[6] In August 2022, Bretagne was despatched to escort the Russian cruiser Marshal Ustinov and the destroyer Vice-Admiral Kulakov during their transit through the Bay of Biscay following the deployment of the Russian vessels from their Northern Fleet bases on the Kola Peninsula to the Mediterranean.
