Hawaiian Air Force

Hawaiian Air Force. It was a Numbered Air Force of the United States Army Air Corps, established in 1939 to centralize air defense and operational command in the Territory of Hawaii. The unit played a critical role during the Attack on Pearl Harbor and was a foundational precursor to major United States Army Air Forces commands in the Pacific Ocean theater of World War II. It was redesignated as the Seventh Air Force in February 1942, continuing its mission throughout the war.

History

The Hawaiian Air Force was activated on **1 November 1939** at Fort Shafter, consolidating all United States Army Air Corps units stationed in the Territory of Hawaii under a single headquarters. Its creation reflected growing pre-war tensions and the strategic importance of the Pacific Ocean following Japanese expansionism and the Second Sino-Japanese War. Prior to its establishment, air units like the 18th Pursuit Group and 5th Bombardment Group operated separately under the command of the United States Army's Hawaiian Department. The force's early years focused on training and building infrastructure, including developing airfields like Wheeler Army Airfield, Hickam Field, and Bellows Field. Its most defining historical moment was the devastating Attack on Pearl Harbor on **7 December 1941**, during which many of its aircraft were destroyed on the ground and its facilities, particularly Hickam Field, suffered heavy damage. In the immediate aftermath, it participated in initial defensive patrols and recovery operations. The unit was redesignated as the **Seventh Air Force** on **5 February 1942**, as part of a larger reorganization of the United States Army Air Forces for the Pacific War.

Organization and units

The command structure was headquartered at Fort Shafter and initially organized under the Hawaiian Department. Its primary combat components were several groups and squadrons. Key subordinate units included the 18th Pursuit Group, equipped with P-40 Warhawk and P-36 Hawk aircraft and based at Wheeler Army Airfield, and the 5th Bombardment Group, operating B-17 Flying Fortress and B-18 Bolo bombers from Hickam Field. Support and reconnaissance units included the 19th Transport Squadron and various service and materiel squadrons. The force also commanded the Hawaiian Air Depot at John Rodgers Field for maintenance and logistics. Following the Attack on Pearl Harbor, the organization underwent rapid changes, absorbing new personnel and units, and its structure directly evolved into that of the Seventh Air Force.

Aircraft and equipment

The inventory consisted primarily of aircraft that were becoming obsolete at the outbreak of World War II. The main pursuit aircraft were the Curtiss P-40 Warhawk and the older Curtiss P-36 Hawk, which bore the brunt of the Japanese attack. Bomber strength centered on the B-17 Flying Fortress and the largely obsolete Douglas B-18 Bolo. The force also operated a small number of A-20 Havoc attack aircraft and C-33 transport planes. A significant weakness was the lack of a fully integrated radar early-warning system, though the Opana Radar Site was operational. Much of this equipment was destroyed or severely damaged during the Attack on Pearl Harbor, as aircraft were parked closely together for perceived sabotage security rather than dispersal for air attack. Subsequent re-equipment under the Seventh Air Force introduced more modern types like the B-24 Liberator and P-47 Thunderbolt.

Commanders and personnel

The first commanding general was Major General Frederick L. Martin, an experienced aviator who had previously served with the Army Air Corps Tactical School. He was succeeded by Major General Walter C. Short, who also served as commanding general of the Hawaiian Department at the time of the Attack on Pearl Harbor; both generals were relieved of command shortly after the attack amid subsequent investigations. Key subordinate officers included Brigadier General Howard C. Davidson and Colonel William E. Farthing. The personnel consisted of a mix of regular United States Army officers, enlisted airmen, and support staff. Notable figures who served within its ranks included future General of the Air Force Henry H. Arnold, who had earlier conducted important inspections, and Captain Gordon H. Austin, a pilot awarded the Distinguished Service Cross (United States) for actions during the Pearl Harbor attack.

Role and operations

Its primary role was the aerial defense of the Territory of Hawaii and key installations like Pearl Harbor, Schofield Barracks, and the Panama Canal. Routine operations involved extensive training exercises, long-range reconnaissance patrols over the Pacific Ocean, and inter-service coordination with the United States Navy's Pacific Fleet. The catastrophic failure of its defensive mission during the Attack on Pearl Harbor led to immediate changes in tactics, including instituting dawn patrols and dispersing aircraft. In the weeks following the attack, it conducted limited patrol and search missions for suspected Imperial Japanese Navy forces. Its operational legacy was inherited and vastly expanded by the Seventh Air Force, which conducted strategic bombing, close air support, and long-range reconnaissance across the Central Pacific Area, including campaigns in the Gilbert and Marshall Islands, the Battle of the Philippine Sea, and the Battle of Okinawa.
