Republic of Vietnam Sailor's Cap with variations of cap badges,
circa 1960s-70s, RVNHS Archive.
At its height, the Republic of Vietnam Navy ( Hải quân Việt Nam Cộng hòa ) consisted of over 42,000 personnel, 14,000 vessels, and dozens of operating bases along the coasts and waterways of Vietnam. It was not only the largest navy in Southeast Asia at the time, but also one of the largest in the world. The cap shown here was the standard sailor's cap worn by enlisted personnel. This style of cap, sometimes referred to as a "Dixie cup" - in reference to the disposable drinking cups, has been utilized by the navies of multiple nations. These caps worn by Republic of Vietnam sailors did not always feature insignia. It is generally believed caps from the earlier years were more likely to have insignia, with the use of insignia decreasing in frequency in later years. This cap from the RVNHS Archive is shown alongside two variations of the cap insignia. The insignia on the cap is believed to be an earlier version, while the other two are later. However, photographic evidence exists showing the earlier version still in use by some into the 1970s.
