HMJS CAGWAY, located in picturesque and historic town of Port Royal, is the home of the sailors and naval officers in the Jamica Defence Force Coast Guard. On 19 May 1968, approximately two years after being relocated from Princess Street (Downtown), Kingston, the Coast Guard base was formally Commissioned as Her Majesty’s Jamaica Ship (HMJS) Cagway.

The name Cagway was given to the westermost end of the Palisadoes Strip by the British. It is a corruption of the Spanish word "Caguaya" which is part of the name "Punta Caguaya" given to the same place by the Spanish.

The base at Port Royal was originally intended as temporary accommodation, but has now become the permanent home of the JDF Coast Guard. In 1984 the size of the base was increased when the Coast Guard took over the building that formerly housed the Police Training School, after the school was transferred to Twickenham Park in St. Catherine.

The location of the base is steeped in military history, not only because it is located in historic Port Royal, but also that the ammunition dump that supplied the Forts that defended the approaches to Kingston Harbour in the days of the wars between the Spanish, English and French is located on the same compound. The remainder of the train line that was used to supply Fort Rocky and Fort Charles can still be seen today.The ammunition dump continues to be used by the JDF.

The buildings that were constructed for the base in the early 70s are made of wood. A new two-storey concrete structure which is to be the Coast Guard Operations Building now dominates the compound. It was built last year as part of the Joint Overseas Training program with the United States Naval Construction Battalion (Seabees) and soldiers from I Engineer Regiment (JDF). The Wardroom is of ancient Spanish brick and there are few other buildings of the same construction which are dated as the history of Port Royal itself.

Station Discovery Bay was established 01 December 1988 and serves as a central point for launching operations on the north coast of the island.
