On 6 July, the French naval command ordered Gensoul to return to Toulon; he arrived and raised his flag aboard Strasbourg later that day.
Repairs to the damage incurred during the attack were completed quickly, and in August the command reorganized the fleet.
The prewar units were dissolved between 8 and 12 August; during this period, Gensoul left the vessel on the 10th.
Strasbourg was assigned to the 3rd Squadron and on 14 August she was taken into the shipyard in Toulon to have screens installed to protect the anti-aircraft gun crews.
She emerged from the yard on 11 September and two weeks later, the naval command created the Forces de haute mer (High Seas Forces), with Strasbourg serving as its flagship under Amiral Jean de Laborde.
At the time, the fleet also included the heavy cruisers Algérie, Foch, and Dupleix and the light cruisers Marseillaise and La Galissonnière.

On 5 November, Strasbourg and all of the cruisers except Algérie sortied to receive the old battleship Provence, which had been damaged during the attack on Mers-el-Kébir and then repaired.
Provence was escorted by a group of five destroyers, and the two units met off the Balearic Islands and arrived back in Toulon on 8 November.
The next two years passed uneventfully, in large part due to the restrictions on French naval activities under the armistice with Germany.
Training operations were limited to two per month, and the cruisers and destroyers had to alternate between periods of active service and reserve status with skeleton crews.
Strasbourg went into drydock from 15 April to 3 May 1941 for periodic maintenance, and in December she steamed to visit Marseille for four days.
The ship was drydocked again on 31 January 1942 for a major refit that included the installation of radar.
Her anti-aircraft battery was also modified.
The work was completed on 25 April and she returned to service on the 27th.
She had to be drydocked for repairs that lasted for five days to her rudder motors in mid-July.
