The culmination of more than 50-years research, this first volume in a multi-volume set describes in detail, for the first time, the extraordinary array of classic aircraft that deployed to defend the vital Panama Canal and its approaches during World War II. Unlike their combat brethren in the European and Pacific theaters, the units, aircraft and airmen of the Sixth Air Force - often cited as the Forgotten Air Force - have been all but ignored in the vast body of literature that has been published since the war.

While primarily charged with defending the vital Canal which, during the first year of America’s war was viewed as almost certainly the next obvious target of Axis aggression from both the Atlantic and Pacific approaches, the tropical warriors were also plunged into the shooting war that soon saw German and Italian submarines rampaging through the Caribbean. During the first 18 months following Pearl Harbor, unbeknownst to the average Allied citizen on the home front, the submarine offensive nearly severed the vital oil lifeline from the Maracaibo, Venezuela fields, and the equally priority bauxite mines in Surinam, a mineral needed to make aluminum. More than 330 surface vessels were sunk in the Caribbean and its approaches during that period, and the aircraft and units of the Sixth Air Force and a regional offshoot, the Antilles Air Command, created to deal specifically with the submarine menace, saw hitherto undocumented combat in one-on-one actions that have eluded historians. Faced with defending a huge geographic region, stretching from Atkinson Field, British Guyana on the east, up through the entire Antilles chain to Cuba, west through the Caribbean to the Canal itself, and then up and down the Central American and mainland South American landmass from Guatemala City to Talara, Peru and Salinas, Ecuador - the extremely dispersed units of Sixth Air Force anchored their western defenses in the remote and mysterious Galapagos Islands, far to the west.The defenders of the Canal soon realized that this vast and largely over-water operating area demanded camouflage for its aircraft that the standard, prescribed USAAF mix did not provide. As a result, for the first two full years of the war, Sixth Air Force leaders evolved markings unique within the Army Air Forces and, for the first time, a coherent description of these often-exotic schemes are detailed in this ground-breaking series. But besides the overall schemes applied, Sixth Air Force and Antilles Air Command crews, nearly always operating in squadron-size elements or smaller, saw no utility in the unit code identifiers applied to USAAF aircraft in Europe and the Pacific, where large formations required a means of identifying members of individual operating units. Instead, they relied upon a system of so-called unit numbers and color coding of easily recognizable aircraft components, such as prop spinners, fin tips and the individual unit numbers themselves. The defense of the Canal was a classic instance of point defense as preached at the Air Corps Tactical School at Maxwell Field during the pre-war years, and against which many major USAAF wartime aircraft series were in fact designed and evolved. Consequently, heavily armed variants of the oft-maligned Bell P-39 Airacobra series predominated during the war - and the fact that they were also found to be nearly ideal for anti-submarine surface actions, was an added bonus. Curtiss P-40s were also issued in numbers and it wasn’t until late in the war that the P-39s were finally withdrawn and replaced with the superb Lockheed P-38 Lightning, nearly ideal for the threat posture that proved the reality in the Caribbean.
