World War II

James continued civilian pilot training under the government-sponsored Civilian Pilot Training Program. He then enlisted in the Aviation Cadet Program of the United States Army Air Forces on January 18, 1943, receiving his commission as a second lieutenant and pilot wings at Tuskegee Army Airfield, Alabama, on July 28, 1943.^[4] He remained at Tuskegee as a civilian instructor pilot in the Army Air Corps later that July. Throughout the remainder of the war, James trained pilots for the all-Black 99th Pursuit Squadron.

After completing P-40 Warhawk training and then B-25 Mitchell training, James served as a B-25 pilot with the 617th Bomb Squadron of the 477th Bomb Group at Godman Army Airfield and then at Lockbourne Army Airfield from January 1944 until the end of the war.

While arrested for participating in the Freeman Field mutiny, James smuggled out press releases written by Coleman Young.^[5] James did not see combat himself until the Korean War.^[6][7]

While serving in Lockbourne, James next served as a P-47 Thunderbolt pilot with the 301st Fighter Squadron from July 1947 to October 1948, and then served as on the staff of the 332nd Air Base Group at Lockbourne from November 1948 to September 1949.

Korean War

In September 1949, James went to the Philippines as flight leader for the 12th Fighter-Bomber Squadron, 18th Fighter Wing at Clark Field. In July 1950 he left for Korea, where he flew 101 combat missions in F-51 Mustang and F-80 aircraft. His combat missions were with the 67th Fighter Bomber Squadron, 12th Fighter Bomber Squadron, and 44th Fighter Bomber Squadron.

After Korea

James returned to the United States, and in July 1951 went to Otis Air Force Base, Massachusetts, as an all-weather jet fighter pilot with the 58th Fighter-Interceptor Squadron, later becoming operations officer. In April 1953, he became commander of the 437th Fighter-Interceptor Squadron, and assumed command of the 60th Fighter-Interceptor Squadron in August 1955. While stationed at Otis, he received the Massachusetts Junior Chamber of Commerce 1954 award of "Young Man of the Year" for his outstanding community relations efforts. On August 15, 1954, he appeared as a contestant on the game show What's My Line? He graduated from the Air Command and Staff College in June 1957.

James next was assigned to Headquarters U.S. Air Force as a staff officer in the Air Defense Division of the Office of the Deputy Chief of Staff for Operations. In July 1960 he was transferred to RAF Bentwaters in England, where he served successively as assistant director of operations and then director of operations, 81st Tactical Fighter Wing; commander, 92nd Tactical Fighter Squadron; and deputy commander for operations for the 81st Wing. In September 1964, James was transferred to Davis-Monthan Air Force Base, Arizona, where he was director of operations training and later deputy commander for operations for the 4453rd Combat Crew Training Wing.

Vietnam War

James went to Ubon Royal Thai Air Force Base, Thailand, in December 1966, as deputy commander for operations, 8th TFW. In June 1967, under Colonel Robin Olds, he was named wing vice commander when Col. Vermont Garrison completed his tour. Both in their mid-40s, they formed a legendary team nicknamed "Blackman and Robin". James flew 78 combat missions into North Vietnam, many in the Hanoi/Haiphong area, and led a flight in the "Operation Bolo" MiG sweep in which seven Communist MiG-21s were destroyed, the highest total kill of any mission during the Vietnam War.

After Vietnam

He was named vice commander of the 33rd TFW at Eglin Air Force Base, Florida, in December 1967. While stationed at Eglin, the Florida State Jaycees named James as Florida's "Outstanding American of the Year" for 1969, and he received the Jaycee Distinguished Service Award. He was transferred to Wheelus Air Base in the Libyan Arab Republic in August 1969 as Commander of the 7272nd Fighter Training Wing.

Following the coup engineered by radical Libyan officers, including Mohammar Qaddafi, James had a tense standoff with the militants in the late stages of turning Wheelus over to the Libyans. James was determined not to be pushed off the base early, but Qaddafi and his followers began pushing the Americans to see how far they could go and at one point "ran a column of half-tracks through the base housing area at full speed". Following this escalation, James closed the gates of the base. Qaddafi arrived at the gate and while talking to James, moved his hand over to his pistol holster to which James replied: "I told him to move his hand away. If he had pulled that gun, his hand would have never cleared the holster."^[8]

In March 1970 James was promoted to brigadier general and became Deputy Assistant Secretary of Defense (Public Affairs).^[4] James played a key role in rejecting the accuracy of a list of prisoners of war supplied by North Vietnam, despite widespread agreement within the U.S. government that it was in close accord with intelligence estimates. That rejection, in turn, bolstered the politically explosive myth that the communists deliberately were holding prisoners as hostages for some future leverage.^[9]

He was designated principal Deputy Assistant Secretary of Defense (Public Affairs) in April 1973. On September 1, 1974, he assumed duty as vice commander of the Military Airlift Command (MAC), headquartered at Scott Air Force Base, Illinois, as a Lieutenant General.^[4]

On September 1, 1975, James was promoted to the four-star rank of general (O-10), becoming the highest ranking African-American in the history of the United States military to that date.^[4] He was assigned as commander in chief of NORAD/ADCOM at Peterson Air Force Base, Colorado. In these dual capacities, he had operational command of all United States and Canadian strategic aerospace defense forces. On December 6, 1977, he assumed duty as special assistant to the Chief of Staff, U.S. Air Force.^[10]

James retired from the Air Force on February 1, 1978.^[11]
