When the magazines of the semi-dreadnought exploded in Toulon on 25 September 1911, flying debris from the explosion killed four men aboard "Suffren". The ship was reassigned to the 2e Division cuirassée of the 2e Escadre de ligne as a replacement for the destroyed battleship. She was transferred to the 1re Division cuirassée of the 3e Escadre de ligne on 14 March 1913 and became the flagship of Laurent Marin-Darbel, commander of the Escadre de ligne, four days later. The annual manoeuvres of the 1er Armée Navale began on 19 May; when they were concluded the ships were reviewed by President Raymond Poincaré. The 3e Escadre de ligne was dissolved on 11 November and "Suffren" became the flagship of (Rear Admiral) Gabriel Darrieus, commander of the Division de complément (Complementary Division), four days later and he was relieved in his turn by Émile Guépratte on 1 April 1914. During a fleet exercise on 28 May, "Suffren" accidentally rammed the battleship ; the latter ship was undamaged, but "Suffren" had her port anchor and hawsepipe carried away and a hole punched in her hull that forced her to return to port for emergency repairs.
