Canadian RCN Navy HMCS Onondaga SS-73 Baseball Cap Hat

The Canadian RCN Navy HMCS Onondaga SS-73 Baseball Cap Hat is a headwear item associated with the Royal Canadian Navy’s Oberon-class submarine, HMCS Onondaga (SS-73). Commissioned in 1967, HMCS Onondaga served primarily as a patrol and training vessel during the Cold War era, operating both in Canadian waters and on overseas deployments. This cap typically features embroidered insignia or text identifying the submarine by name and hull number, making it recognizable among naval and military enthusiasts. Constructed from standard baseball cap materials, it includes an adjustable strap for size adjustment and a curved brim for sun protection. Caps like these are commonly produced for crew members, veterans, and collectors as a form of unit pride or memorabilia. The HMCS Onondaga was decommissioned in 2000 and is preserved as a museum ship in Rimouski, Quebec, enhancing the historical significance of items bearing its designation.
