The Bird-class patrol vessels were a class of seaward patrol vessels operated by the Royal Canadian Navy (RCN) during the Cold War. The class derives its name from large birds found in Canada and was designed by the RCN as a replacement for the remaining Second World War-era Fairmile motor launches used for coastal patrol.^[1]
