Grande Island and the remains of Fort Wint were incorporated into the U.S. Naval Base Subic Bay. The two disappearing guns of Battery Warwick were dismantled by the United States Navy in the 1960s and shipped to Fort Casey in Washington state for renovation and display. The four guns of Batteries Flake and Jewell were removed and divided between Forts Flagler and Casey in Washington state where they remain on display. The guns of Battery Hall remain in place (pictures right). Grand Island was operated for many decades after WW II by Subic Bay US Navy Special Services as an on base resort for US Military and Civilians stationed throughout the Philippines. It was accessible via a small landing craft type boat shuttle service at the pier adjacent to the Alava Carrier Pier in front of the HQ building at Naval Station Subic Bay. During Operation New Life, in 1975, thousands of Vietnamese refugees were sheltered and processed on Grande Island after the fall of Vietnam to North Vietnam. After that rescue mission, which lasted about six months, Grande Island was rehabilitated and was restored to its Special Services resort configuration until 1991. At that time the lease on US military bases expired, and the US bases were closed about the same time they were damaged by the eruption of Mount Pinatubo volcano. Grande Island was restored as a resort after repairs following damage from the Mount Pinatubo volcano eruption. It was restored by the civilian Philippine Subic Bay Free Port Zone Authority following the closure of the Subic Naval Base in 1992.
