Twelfth Air Force

The Twelfth Air Force (12 AF; Air Forces Southern, (AFSOUTH)) is a Numbered Air Force of the United States Air Force Air Combat Command (ACC). It is headquartered at Davis–Monthan Air Force Base, Arizona.

The command is the air component to United States Southern Command (USSOUTHCOM) conducting security cooperation and providing air, space, and cyberspace capabilities throughout Latin America and the Caribbean.

Established on 20 August 1942 at Bolling Field, District of Columbia, 12th Air Force was a United States Army Air Forces combat air force deployed to the Mediterranean Theater of World War II. It engaged in operations in North Africa, the Mediterranean, and Western Europe. During the Cold War, 12 AF was one of the Numbered Air Forces of the United States Air Forces in Europe (USAFE) and later Tactical Air Command (TAC), Its units engaged in combat operations during the Vietnam War, as well as Operation Desert Storm. As a result of the War on Terror, most Twelfth Air Force units have operated in the United States Central Command AOR.

Since 1987, Twelfth Air Force (Air Forces Southern) trains, equips, and prepares assigned units from Air Combat Command and also serves as the air and space component to United States Southern Command.

Mission
The Twelfth Air Force (Air Forces Southern) headquarters is located at Davis–Monthan Air Force Base in Arizona. It reports to Air Combat Command, a major command of the US Air Force.

As the air and space component to US Southern Command (USSOUTHCOM), Air Forces Southern conducts security cooperation and provides air, space, and cyberspace capabilities throughout its area of responsibility, covering Latin America and the Caribbean.

To fulfil these responsibilities it employs a range of Intelligence, Surveillance and Reconnaissance (ISR), intra-theatre airlift and information assets. In addition the 612th Air Operations Center (612th AOC) is responsible for developing strategy and plans to execute air operations in support of US Southern Command objectives. The 612th AOC also provides command and control of all Air Forces Southern assets in its area of responsibility.

Air Forces Southern does not have its own assets, but draws on forces provided to it by US Southern Command. Currently, AFSOUTH manages four rotational Air Force Reserve Command and Air National Guard C-130s based out of Muñiz Air National Guard Base, Puerto Rico.

World War II
The origins of Twelfth Air Force are traced back to a series of mid-1942 Allied planners' meetings to develop a strategy for the invasion of French North Africa (Operation Torch). Because this extensive operation required a new organization to provide enough manpower and equipment, activation plans were prepared simultaneously with the invasion strategy.

On 20 August 1942, Twelfth Air Force was activated at Bolling AAF, Maryland. On 23 September 1942, Brigadier General Jimmy Doolittle formally assumed command with Colonel Hoyt Vandenberg as chief of staff. Barely four months after it was conceived, 12th AF made its first contributions to World War II. When D-Day for the invasion of North Africa (Operation Torch) arrived on 8 November 1942, 12th AF was organized

Initially, 12th AF was a composite organization containing both strategic heavy bombardment groups; and tactical light and medium bombardment, fighter-bomber, and fighter groups. Based in French Morocco and Algeria after Operation Torch, it became very important for 12th AF to coordinate and cooperate with the Royal Air Force which had been fighting in North Africa for two years. Such Allied cooperation was a major concern of American President Franklin D. Roosevelt, British Prime Minister Winston Churchill, and their staffs at the Casablanca Conference in January 1943 where they created the Mediterranean Air Command (MAC) with Air Chief Marshal Sir Arthur Tedder as Air Commander-in-Chief. For planning of the Tunisian campaign, Tedder's MAC headquarters were adjacent to those of his immediate superior, the Supreme Allied Commander, General Dwight D. Eisenhower at Algiers, Algeria soon after the new Allied air force reorganization took effect on 18 February 1943.

The Northwest African Air Forces (NAAF) under Lieutenant General Carl Spaatz was the largest component of MAC and its organization was based on the 'tri-force' model (No. 205 Group 'strategic', No. 201 Group 'coastal', and Air Headquarters Western Desert 'tactical') indicated above. Thus the three major combat commands of NAAF were:
 * Northwest African Strategic Air Force (NASAF) under Major General James Doolittle
 * Northwest African Coastal Air Force (NACAF) under Air Vice-Marshal Hugh Lloyd
 * Northwest African Tactical Air Force (NATAF) under Arthur Coningham.

In keeping with the MAC priority of encouraging USAAF-RAF cooperation, Air Vice-Marshal James Robb was named Spaatz's deputy commander of NAAF and he handled operations.

Additionally, the following new units were assigned to NAAF:
 * Northwest African Air Service Command (NAASC) under Major General Delmar H. Dunton
 * Northwest African Training Command (NATC) under Brigadier General John K. Cannon
 * Northwest African Photographic Reconnaissance Wing (NAPRW) under the president's son, Colonel Elliott Roosevelt
 * Northwest African Troop Carrier Command (NATCC) initially under Colonel Ray Dunn and later under Brigadier General Paul Williams.

Lieutenant General Lewis Brereton's 9th Air Force was assigned to RAF Middle East although its 12th Bombardment (B-25Cs) and 57th Fighter (P-40Fs) Groups formed a Desert Air Task Force detached to NATAF's Western Desert Air Force under Air Vice-Marshal Harry Broadhurst who replaced Coningham when he was promoted to NATAF commander.

The 12th AF, the largest air force ever assembled soon after its inception several months earlier, ceased to exist in the new MAC organizational structure. As an operational organization, the 12th AF simply disappeared when its groups were distributed among the various new NAAF commands. The only remaining reference to the 12th AF among these commands was Major General Edwin House's XII Air Support Command which along with Broadhurst's Western Desert Air Force, Air Vice-Marshal Sir Laurence Sinclair's Tactical Bomber Force, and Air Vice-Marshal Sir Kenneth Cross' No. 242 Group, became part of Coningham's NATAF. Later, XII Air Support Command became even less obvious when it was detached to No. 242 Group. The curious status of the 12th AF in February 1943 is illustrated by the quotation below taken from the official history "One of the admittedly minor problems of the reorganization concerned the status of the Twelfth Air Force. Its units, personnel, and equipment having been transferred entirely to NAAF on February 18, both on paper and in actuality the Twelfth seemed to have vanished. At his last staff meeting, on February 22, Doolittle expressed the opinion that once such matters as courts-martial had been wound up, the "skeleton" of the Twelfth--"the name only"--would have either to be returned to the States for a reincarnation or be decently interred by War Department order. Spaatz put the question to Eisenhower and, receiving answer that Headquarters, Twelfth Air Force, would be continued as the administrative headquarters for the U.S. Army elements of NAAF, he took command of the Twelfth on March 1. As commander, however, he had no staff as such, it being assumed that AAF officers named to the NAAF staff had been automatically placed in equivalent positions in the Twelfth. Actually, all administrative functions were carried on by NAAF and the half-existence of the Twelfth served mainly to mystify all but a few headquarters experts."

Although the 12th AF was essentially unrecognized in the official Allied air force organization (MAC), it was of course, still a major entity in the USAAF. But even the U.S. Army Air Forces World War II Combat Chronology 1941–1945, recorded its daily chronology entries under "NAAF" rather than "12th AF" between 1 March and 1 September 1943. The U.S. Ninth Air Force retained its identity in MAC (and in the USAAF Combat Chronology) even though it was officially a sub-command of RAF Middle East Command and most of its groups were assigned to other operational commands such as NATAF after the February reorganization of the Allied air forces.

On 22 August 1943, the Ninth Air Force's 12th and 340th Bombardment Groups, and its 57th, 79th, and 324th Fighter Groups were transferred to the 12th AF. This change coincided with the transfer of the 9th AF from the MTO to the European Theater of Operations (ETO).

On 1 September 1943 all administrative functions of USAAF elements of NAAF were transferred to the appropriate Twelfth AF organizations: HQ NAAF to HQ Twelfth AF, NASAF to XII Bomber Command, NATAF to XII Air Support Command, NACAF to XII Fighter Command, NAASC to XII AFSC, NAAF TCC to XII Troop Carrier Command (Provisional), NWPRW to Photographic Reconnaissance Wing (Provisional), and NATC to XII Training Command (Provisional) but operational control remained with NAAF.

On 10 December 1943 MAC was disbanded and reorganized as the Mediterranean Allied Air Forces (MAAF) with Air Chief Marshal Sir Arthur Tedder as Air Commander-in-Chief. In mid-January 1944, Lieutenant General Ira Eaker took over MAAF when Eisenhower chose Tedder to oversee air operations and planning for the Normandy Landings. The new MAAF organization retained the original tri-force model adopted by the Casablanca Conference in creating MAC nearly one year earlier:
 * Mediterranean Allied Strategic Air Force (MASAF) under Major General Nathan Twining
 * Mediterranean Allied Coastal Air Force (MACAF) under Air Vice-Marshal Hugh Lloyd
 * Mediterranean Allied Tactical Air Force (MATAF) under Major General John K. Cannon.

Components of the 12th AF, also under Cannon, were assigned to his various MATAF sub-commands after the 12th's heavy bomb groups (and three B-26 medium bomb groups that were eventually returned to the 12th) were transferred to the newly created Fifteenth Air Force (1 November 1943; briefly under Doolittle and then Twining) as part of MASAF. In January 1944, Doolittle took over the 8th AF in England which along with the 15th AF in Italy, formed the United States Strategic Air Forces (USSTAF) under Spaatz.



As the U.S. tactical air force in the Mediterranean, the 12th AF primarily provided close tactical support to U.S. ground forces in Italy and Southern France and targeted lines of transportation and communication, particularly roads, railroads, and bridges until the end of the war.

12th AF operated in the Mediterranean, French Morocco, Algeria, Tunisia, Greece, Italy, Southern France, Yugoslavia, Albania, Romania, and Austria. By V-E Day, 12th AF had flown 430,681 sorties, dropped 217,156 tons of bombs, claimed destruction of 2,857 enemy aircraft, and lost 2,667 of its own aircraft.

When hostilities ended, Twelfth Air Force was inactivated at Florence, Italy, on 31 August 1945.

Colonel Demas T. Craw and Major Pierpont M. Hamilton were awarded the Medal of Honor for heroism during the invasion of Algeria-French Morocco (Operation Torch). When the Allies landed at Mehdia, French Morocco on 8 November 1942, both men volunteered to go behind enemy lines and meet with the French commander near Port Lyautey, French Morocco, to broker a cease fire.

After landing on the beach under hostile fire, Craw, his interpreter Major Pierpont M. Hamilton, and their driver Private Orris Correy approached the French headquarters in a light truck. They came under machine gun fire, leaving Craw dead. Hamilton and Correy were captured. Although imprisoned, Major Hamilton succeeded in persuading the French to surrender and was awarded the Medal of Honor on 19 February 1943. Private Correy was promoted to Sergeant and Pierpont Hamilton, a descendant of Alexander Hamilton, became an intelligence officer in the Northwest African Tactical Air Force a subordinate command of the newly created Northwest African Air Forces under Lieutenant General Carl Spaatz who also assumed administrative command of the Twelfth Air Force on 1 March 1943.

Colonel Demas Craw was awarded his Medal of Honor posthumously on 4 March 1943 and the United States Navy named their air base at Port Lyautey, French Morocco Craw Field in his honor on 12 January 1944. The only member of the Twelfth Air Force to be awarded the Medal of Honor for heroism in the air was Lt. Raymond L. Knight of the 350th Fighter Group.

XII Tactical Air Command was inactivated at Bad Kissingen, Germany, on 10 November 1947.

Cold War
Twelfth Air Force was reactivated at March Field, California, on 17 May 1946, and assigned to Tactical Air Command with training responsibilities.

In the late 1940s, following several assignments and inactivations, 12 AF reactivated on 21 January 1951 at Wiesbaden AB, West Germany, assigned to United States Air Forces in Europe. Twelfth Air Force became the first USAFE formation to be declared available to NATO. Along with French and Canadian air units, 12 AF was part of the Fourth Allied Tactical Air Force, itself part of NATO's Allied Air Forces Central Europe. It included the 21st Fighter-Bomber Wing, located in France, and the 85th Air Depot Wing at Erding in Germany.

On 1 January 1958, Twelfth Air Force relocated to Waco, Texas adjacent to James Connally Air Force Base, Texas, and assigned to Tactical Air Command. During its 10 years at Connally AFB its mission began to focus on training tactical air crews to a state of combat readiness capable of conducting joint air operations.

In September 1968, Twelfth Air Force moved to Bergstrom AFB, Texas. During the Vietnam War, the Twelfth was a primary source for tactical fighter, reconnaissance, and airlift forces deployed to the war zone in Southeast Asia.

In 1987, the Twelfth Air Force commander took on the United States Air Force Southern Command responsibility. As such, 12 AF manages all Air Force personnel and assets in the United States Southern Command area of responsibility--Central and South America. During the United States invasion of Panama in 1989, for example, 12 AF and other Air Force units deployed in support of U.S. forces, returning democracy to Panama. In 1994, 12 AF managed and orchestrated Operation Uphold Democracy's air operations, the mission to restore Haitian democracy while at the same time supporting U.S. Southern Command's Operation Safe Haven for Cuban refugees.

Post Cold War
On 13 July 1993, Headquarters Twelfth Air Force officially moved from Bergstrom AFB to Davis-Monthan AFB, Arizona. Since then, 12 AF personnel and units have participated in operations in many other parts of the world: Southern Watch, Operation Provide Comfort, Operation Deny Flight, Provide Promise, peacekeeping in Somalia (Restore Hope), and JOINT ENDEAVOR. During the Gulf War (Operations Desert Shield and Desert Storm) 12 AF provided fighter and reconnaissance aircraft to support U.S. Central Command Air Forces.

Since the 11 September 2001 terrorist attacks, Twelfth Air Force (Air Forces Southern) has worked closely with Caribbean, Central, and South American countries in the Global War on Terrorism. The command has supported efforts to stem the flow of illegal drugs into the U.S. and neighboring countries. 12 AF has also provided forces to Operations Enduring Freedom Afghanistan, IRAQI FREEDOM, and NOBLE GUARDIAN in the U.S. Today 12 AF directs six combat wings, five Direct Reporting Units, as well as 12 AF gained Air Force Reserve and Air National Guard units.

The Twelfth Air Force served as a USAF headquarters responsible for the combat readiness of six active-duty wings and one direct reporting unit for contingency operations, and oversaw 21 gained units from Air Force Reserve Command and the Air National Guard, totalling more than 630 aircraft with more than 42,000 personnel.

On 20 August 2020, Twelfth Air Force's fighter jets, battle management aircraft, strike drones, and combat search-and-rescue forces were transferred to the newly reformed Fifteenth Air Force. The change is expected to allow Twelfth Air Force to better focus on its mission as air component to US Southern Command. The following units were subordinate to the Twelfth Air Force prior to their transfer to the Fifteenth Air Force.
