Hispanics in the United States Air Force can trace their tradition of service back to the United States Army Air Forces (USAAF), the military aviation arm of the United States Army during and immediately after World War II. The USAAF was the predecessor of the United States Air Force, which was formed as a separate branch of the military on September 18, 1947, under the National Security Act of 1947. In the U.S., the term Hispanic categorizes any citizen or resident of the United States, of any racial background, of any country, and of any religion, who has at least one ancestor from the people of Spain or is of non-Hispanic origin but has an ancestor from Mexico, Puerto Rico, Cuba, Central or South America, or some other Hispanic origin. The three largest Hispanic groups in the United States are the Mexican-Americans, Puerto Ricans, and Cubans.Hispanic Population of the United States Current Population Survey Definition and Background , United States Census Bureau, Population Division, Ethnic & Hispanic Statistics Branch, Retrieved May 21, 2008 According to the U.S. Census Bureau the estimated Hispanic population of the United States is over 50 million, or 16% of the U.S. population, and Hispanics are the nation's largest ethnic minority. The 2010 U.S. census estimate of over 50 million Hispanics in the U.S. does not include the 3.9 million residents of Puerto Rico, thereby making the people of Hispanic origin the nation's largest ethnic or race minority as of July 1, 2005.

Hispanics, both men and women, have reached the top ranks of the Air Force, serving their country in sensitive leadership positions on domestic and foreign shores. Hispanics, however currently account for a total of 4.9% of the enlisted personnel making the United States Air Force the military branch with the lowest average of Hispanic recruits.

Prelude to World War II Before the United States entered World War II, Hispanic Americans were already fighting on European soil in the Spanish Civil War. The Spanish Civil War was a major conflict in Spain that started after an attempted coup d'état by parts of the army, led by the Nationalist General Francisco Franco, against the government of the Second Spanish Republic. Hispanic Americans fought on behalf of both of the factions involved, the "Nationalists" as members of the Spanish Army and the "Loyalists" (Republicans) either as members of the Abraham Lincoln International BrigadeLatinos who fought in Spain.

United States Army Air Forces and World War II

When the United States officially entered the war on December 7, 1941, Hispanic Americans were among the many American citizens who joined the ranks of the United States Armed Forces as volunteers or through the draft. Some Hispanics, such as Mihiel "Mike" Gilormini and Alberto A. Nido, served and fought for two different countries as members of the Royal Canadian Air Force and the British Royal Air Force before joining the United States Army Air Forces.Negroni, Héctor Andrés. Historia Militar de Puerto Rico (A Military History of Puerto Rico). Turner Publishing. 1992. . p 486.

Those who were qualified pilots or had received private flying lesson were assigned to the newly formed United States Army Air Forces (USAAF) and served as active combatants in both the European and Pacific Theaters of war.

In 1944, Puerto Rican aviators were sent to the Tuskegee Army Air Field in Tuskegee, Alabama to train the famed 99th Fighter Squadron of the Tuskegee Airmen. The Tuskegee Airmen were the first African-American military aviators in the United States armed forces. Puerto Ricans were also involved in clerical positions with the Tuskegee unit. Among the Puerto Ricans who helped make the Tuskegee experiment a successful one were T/Sgt. Pablo Diaz Albortt, an NCO (Non Commissioned Officer) in charge of the Special Service Office, and Eugene Calderon, who was assigned to the "Red Tail" unit, as the Company Clerk."The Tuskegee Airmen: The Men who Changed a Nation"; By: Charles E. Francis, pg. 370; Publisher: Branden Books, 1997; , 9780828320290 By the end of the war, the Tuskegee Airmen were credited with 109 Luftwaffe aircraft shot down, a patrol boat run aground by machine-gun fire, and destruction of numerous fuel dumps, trucks and trains.

The inherent flexibility of air power

Among the Hispanics who played an instrumental role as a commander during the conflict was Brigadier General Elwood R. "Pete" Quesada, (1904–1993). Quesada, (who eventually would become a lieutenant general), was assigned as a brigadier general in October 1940 to intelligence in the Office of the Chief of Air Corps. He became commanding general of the 9th Fighter Command where he established advanced headquarters on the Normandy beachhead on D-Day plus one, and directed his planes in aerial cover and air support for the Allied invasion of the European continent. He was the foremost proponent of "the inherent flexibility of air power", a principle he helped prove during World War II.Elwood Richard Quesada: Lieutenant General, United States Air Force. Arlington National Cemetery. Retrieved on July 10, 2007.

In December 1942, Quesada took the First Air Defense Wing to North Africa. Shortly thereafter, he was given command of the XII Fighter Command and in this capacity would work out the mechanics of close air support and Army-Air Force cooperation.

The successful integration of air and land forces in the Tunisia campaign forged by Quesada and the Allied leaders became a blueprint for operations incorporated into Army Air Forces field regulations—FM 100-20, "Command and Employment of Air Power", first published on July 21, 1943—and provided the Allies with their first victory in the European war. Principles such as the co-equality of ground and air force commanders, centralized command of tactical aircraft to exploit "the inherent flexibility of air power", and the attainment of air superiority over the battlefield as a prerequisite for successful ground operations formed the core of tactical air doctrine. In October 1943, Quesada assumed command of the IX Fighter Command in England, and his forces provided air cover for the landings on Normandy Beach. Among Quesada's many military decorations were the Distinguished Service Medal with oak leaf cluster; Distinguished Flying Cross; Purple Heart and an Air Medal with two silver star devices.

Fighter pilots and bombardiers

A "flying ace" or fighter ace is a military aviator credited with shooting down five or more enemy aircraft during aerial combat. The term "ace in a day" is used to designate a fighter pilot who has shot down five or more enemy aircraft in a single day.Aces of the 78th. 78thfightergroup.com. Retrieved on June 27, 2007. Since World War I, a number of pilots have been honored as "Ace in a Day".1st. Lt. Oscar Perdomo. Cavanaugh Flight Museum. Retrieved on August 5, 2007.

First Lieutenant Oscar F. Perdomo, (1919–1976), the son of Mexican parents, was born in El Paso, Texas. When the war broke out, Perdomo joined the United States Army Air Forces (USAAF) as an aviation cadet and was trained to pilot the P-47 Thunderbolt. After receiving his pilot training, he was assigned to the 464th Fighter Squadron, which was part of the 507th Fighter Group that was sent to the Pacific Island of Ie Shima off the west coast of Okinawa.

The atomic bomb was dropped on Nagasaki, Japan on August 9, 1945, but while the Allies awaited Japan's response to the demand to surrender, the war continued. On August 13, 1945, 1st Lt. Perdomo shot down four Nakajima Ki-84 "Frank" fighters and one Yokosuka K5Y "Willow" Type 93 biplane trainer. This action took place near Keijo/Seoul, Korea when 38 Thunderbolts of the 507th Fighter Group encountered approximately 50 enemy aircraft. This action was Lt. Perdomo's tenth and final combat mission, and the five confirmed victories made him an "Ace in a Day" and earned him the distinction of being the last "Ace" of World War II. He was awarded the Distinguished Service Cross for extraordinary heroism in action and the Air Medal with one oak leaf cluster.

Lieutenant Colonel Donald S. Lopez Sr., USAAF fighter ace was assigned to the 23rd Fighter Group under the command of General Claire Chennault. The mission of the fighter group (the "Flying Tigers") was to help defend Chinese nationals against Japanese invaders. During 1943–1944, Lopez was credited with shooting down five Japanese fighters, four in a Curtiss P-40 and one in a North American P-51.

Captain Michael Brezas, USAAF fighter ace, arrived in Lucera, Italy during the summer of 1944, joining the 48th Fighter Squadron of the 14th Fighter Group. Flying the P-38 aircraft, Lt. Brezas downed 12 enemy planes within two months. He received the Silver Star Medal, the Distinguished Flying Cross, and the Air Medal with eleven oak leaf clusters.Captain Micheal Brezas.

2nd Lieutenant César Luis González, a co-pilot of a C-47, was the first Puerto Rican pilot in the United States Army Air Forces. He was one of the initial participants of the invasion of Sicily on July 10, 1943, also known as Operation Husky. During the invasion of Sicily, he flew on two night missions, the first on July 9, where his mission was to release paratroops of 82nd Airborne Division on the area of Gela and the second on July 11, when he dropped reinforcements in the area. His unit was awarded a "DUC" for carrying out this second mission in spite of bad weather and heavy attack by enemy ground and naval forces. González died on November 22, 1943, when his plane crashed during training off the end of the runway at Castelvetrano. He was posthumously promoted to first lieutenant
