Context: Island School is a private, co-educational, independent school (pre-kindergarten through high school) on the island of Kauai in Kauai County, Hawaii, United States.  The school is located behind the University of Hawaii's Kauai Community College campus near the community of Lihue. The region's premier installation and headquarters installation, Joint Base Pearl Harbor–Hickam is host two of United States Pacific Command subordinate Service components - United States Pacific Fleet on the Pearl Harbor side, and Pacific Air Forces on the Hickam side.  The region also oversees installation support for the Pacific Missile Range Facility, the world's largest instrumented, multi-dimensional testing and training missile range in Kekaha, Hawaii. The Naval Facility (NAVFAC) Barbados, TWI was a naval base which was commissioned on 1 October 1957, with a complement of about 12 officers and about 88 enlisted personnel.  It was located at site of Harrison's Point, in the Parish of Saint Lucy in the British colonial territory of Barbados of the West Indies.  The facility opened about one-month following the U.S. Navy Facility established in the island of Eleuthera in The Bahamas.  NAVFAC Barbados was operated by the United States Navy for twenty-two years and was officially decommissioned on 31 March 1979.

Port Allen is a populated place at Hanapepe Bay, 20 nautical miles from Nawiliwili, in Kauai County, in the U.S. state of Hawaii.  Originally named ʻ Eleʻ ele Landing, terminal owner Kauai Railway renamed it for Honolulu business man and port financial backer Samuel Clesson Allen.  When the Civilian Conservation Corps Camp in Koke'e State Park was built in 1935, the lumber for the camp was floated ashore at Port Allen.  Captain James Cook landed on Kauai in this area.  The facilities were demolished in 1982 by Hurricane Iwa, but eventually rebuilt. A Service Squadron (ServRon) was a U.S. Navy squadron that supported fleet combat units.  Service Squadrons were used by the United States Navy from their inception in 1943 to as late as the early 1980s.  At the time of their inception during the Second World War they allowed the US Navy to operate across the vast reaches of the Pacific ocean for extended periods of time.  Service Squadrons created temporary forward bases to allow the naval squadrons to spend less time in transit and more time in the area of combat.  Ulithi, a small volcanic atoll in the central Pacific, is one such example.  Service Squadrons essentially created a major naval base near the area of operation.  With the naval base at Ulithi to refit, repair and resupply, many ships were able to deploy and operate in the western Pacific for a year or more without returning to a major port facility.  Among the vessels operating in service squadrons were tankers, oilers, refrigerator ships, ammunition ships, supply ships, floating docks and repair ships.  They provided diesel, ordnance, aviation fuel, food stuffs and all other supplies.  Equally important at places like Ulithi were the portable piers and floating dry docks which allowed many ships damaged by enemy action or Pacific storms to undergo repair without having to travel the thousands of miles back to a major US naval base.  Ulithi was as far forward from the US naval base at San Francisco as the San Francisco base was from London, England.  To have a fully functional major port in the middle of the Pacific was a significant aid to U.S. Navy operations.
