With the loss of area air defence capabilities in 2015 (and, temporarily, at-sea replenishment capabilities), the RCN was, at that time, classified as a Rank 5 navy (offshore regional coastal defence) on the Todd-Lindberg navy classification system, dropping from Rank 3 (multiregional power projection). In 2011, the government restored the traditional name of the Royal Canadian Navy, removed at the unification of the Canadian Armed Forces in 1968. Commissioned vessels are designated as 'Her Majesty's Canadian Ship' (HMCS), minor ships as 'Patrol Craft Training' (PCT) and auxiliaries as 'Canadian Forces Auxiliary Vessel' (CFAV).
