Class Notes:
Proton and Chimon were inspected in September 1957 while still active and found fit for future service. However subsequently they were stripped of their General Stores Issue facilities which were used for the modernization of Pollux (AKS 4), resulting in seriously impairing their mobilization potential as AKS.
