Naval Base Puerto Princesa, Naval Base Palawan, was a United States Navy base built during World War II at Puerto Princesa on Palawan Island, Philippines, after the Invasion of Palawan on February 28, 1945. Puerto Princesa Bay offered an excellent base for fleet anchorage. At the naval base, US Navy Seabees built: a seaplane base, carrier aircraft fighter plane repair depot, land airfield and other base facilities.[1]
Palawan Island is an eastern island of the Philippines and is the fifth largest of the Philippine islands. The island is 265 miles long and about 25 miles wide. The 84th Seabee Construction Battalion arrived at Puerto Princesa on March 12, 1945. Most of the captured Japanese facilities had been destroyed in bombing raids. One captured runway was easily repaired and was selected for repair and lengthening. The 84th Seabee Construction Battalion unloaded and loaned the needed equipment to the United States Army Engineers to work on the runway. The 84th Seabee Construction Battalion built all the other support facilities at the airfield. At the same time, the 84th Seabee Construction Battalion built all the needed port facilities. A large repair dept called a Carrier Aircraft Service Unit was built to service the planes on carrier aircraft. Naval Base Puerto Princesa was support by the very large Leyte-Samar Naval Base, east of Puerto Princesa. After the war, the base was closed and abandoned.[2]
Puerto Princesa Seaplane Base opened May 15, 1945. Seaplane ramps and a land base was built. A 500-man camp to support the base was built. The USS Pocomoke (AV-9), a seaplane tender serviced the planes of the US Navy Patrol Squadron, VP-17.[3]
