Luna Airfield

Military abandonment following the conclusion of World War II. Luna Airfield was a temporary combat airfield constructed by the U.S. Army for the specific purpose of supporting the Philippines Campaign (1944-1945). With the surrender of Japan in August 1945, the strategic need for the airfield ceased. The American military units were redeployed, and the airfield was turned over to the Philippine government and subsequently fell into disuse as the land was reclaimed for civilian purposes.

The site of the former Luna Airfield has been completely converted to civilian use. The distinct, long, straight outline of the main runway is still clearly visible in satellite imagery, but the land itself is now primarily agricultural, covered with rice paddies and other farmland. The main provincial road (Bacnotan-Luna-Balaoan Road) and several smaller local roads cut directly across the former runway. Residential houses and small communities have also been built on and adjacent to the old airfield grounds. No original aviation infrastructure, such as hangars, control towers, or terminal buildings, remains.

Luna Airfield was a significant forward operating base for the United States Army Air Forces (USAAF) Fifth Air Force during the liberation of the Philippines in World War II. Constructed in early 1945, it played a crucial role in the final months of the war. It hosted several key units and aircraft types:
- **312th Bombardment Group:** Flew A-20 Havoc attack bombers on missions against Japanese forces remaining in Luzon and Formosa (now Taiwan).
- **433rd Troop Carrier Group:** Operated C-47 Skytrain and C-46 Commando transport aircraft, moving troops, supplies, and evacuating wounded personnel.
- **35th Fighter Group:** Flew P-51 Mustang fighters, providing escort for bombers and conducting fighter sweeps.
The airfield was a critical hub for launching tactical air strikes, supporting ground troops, and staging assets for the planned but ultimately unnecessary invasion of Japan (Operation Downfall). Its existence was vital for projecting Allied air power in the region during that period.

There are no known or official plans to reopen Luna Airfield. The land has been privately owned and extensively developed for agriculture and housing for over 75 years. The cost and logistical challenges of acquiring the land, clearing the existing structures and roads, and rebuilding the airport to modern standards would be prohibitive. Aviation needs for the province of La Union are served by San Fernando Airport (RPUF).
