US Navy Seabees began construction of NAS Cubi Point at the Subic Bay Naval Base in the Philippines and completed work on the air station in 1956. Admiral Arthur W. Radford, the C-in-C for the US Pacific Fleet, made the inaugural landing himself on the new runway. In honor of the Seabee battallion that constructed the base, Construction Battallion One (CUB 1), the base was named CUB1 Point but over the years became better known as "Cubi Point".
