Nine ships of this class were rebuilt in 1927, and serve in 9th Flotilla Torpillieurs - Mediterranian Fleet, Beiruit. The remaining 15 ships were rebuilt in 1933 for use as screens for the Petain class coast defense battleships. Each Petain has an escort of 3 Aventurieur class destroyers.

All 24 ships of this class were retired and scrapped in early 1942.
