The Protecteur-class auxiliary oiler replenishment (AOR) ships were used by the Royal Canadian Navy to resupply ships at sea with food, munitions, fuel and spare parts. They had more sophisticated medical and dental facilities than smaller warships. At 172 metres (564 ft) the ships were some of the largest operated by the RCN. Entering service in 1969, the last vessel of the class was paid off in 2016.
