Naval Base Subic Bay, located at Olongapo on Luzon Island in the Philippines, served as the US Navy’s primary forward operating base in the western Pacific throughout World War II, the Korean War, the Vietnam War, and the Cold War. The base hosted a large naval shipyard — initially designated as the Subic Bay Naval Shipyard and later as the Naval Ship Repair Facility (SRF) Subic Bay — which performed voyage repairs, restricted availabilities, and casualty repairs on Pacific Fleet vessels operating in the western Pacific. Naval Base Subic Bay was closed and turned over to the Philippine government in 1992 following negotiations after the Mount Pinatubo eruption.

The SRF Subic Bay performed shipyard repair work on Pacific Fleet vessels requiring the same categories of insulation work as stateside naval shipyards:

  • Insulation trades at SRF Subic Bay performed boiler and steam plant insulation work — stripping and replacing asbestos insulation on destroyers, cruisers, carriers, and submarines undergoing repair at the Subic Bay facility. Vietnam-era damage repairs on vessels hit during combat operations required extensive shipyard work involving insulation removal and replacement
  • Pipe shop and engineering repair at SRF Subic Bay used asbestos gaskets and packing materials in the same pattern as stateside naval ship repair work
  • Dry dock availability work at the Subic Bay drydocks placed engineering rates and shipyard workers in proximity to asbestos insulation removal and replacement work in the confined drydock environment

Shore Infrastructure and WWII-Era Construction

Naval Base Subic Bay’s shore infrastructure was substantially built during World War II and the immediate postwar period, using building materials of the era:

  • WWII-era barracks and administrative buildings on the Subic Bay installation used asbestos-containing materials in construction — asbestos floor tile, overhead lagging, and building mechanical systems using asbestos-insulated pipe
  • Boiler plant and steam heating systems serving the large shore installation used asbestos-insulated pipe and equipment in the base steam heating distribution
  • Industrial buildings in the SRF complex used asbestos-containing fireproofing on structural steel and asbestos in building mechanical systems

Vietnam-Era Usage

Naval Base Subic Bay was the primary repair and support base for US Navy forces operating in Vietnamese waters during the Vietnam War. Ships damaged in combat operations in the Gulf of Tonkin and off the Vietnamese coast were directed to Subic Bay for emergency repairs and voyage damage repair. Crews aboard vessels undergoing Vietnam damage repairs at Subic Bay were present during shipyard repair work involving asbestos insulation in the ship’s engineering spaces.

VA Claims for Subic Bay Veterans

VA presumptive service connection under 38 CFR § 3.309(d) covers asbestos exposure at Navy installations and shipyard facilities. Veterans who served at Naval Base Subic Bay — aboard vessels undergoing SRF repair, at the shipyard, or in shore commands — and have since been diagnosed with mesothelioma, asbestosis, or asbestos-related lung cancer may qualify for VA disability benefits.
