Major General Chesley G. Peterson (August 10, 1920 – January 28, 1990) was a career officer in the United States Air Force, and a flying ace of the United States Army Air Forces (USAAF) in World War II. As a fighter pilot in the European theater, he is best known for his time as the commander of the famous 4th Fighter Group during 1942–1943. At 23, he was the youngest colonel in the USAAF. Early years Peterson was born in Idaho, but moved to Utah in his childhood. He joined the Utah National Guard in 1937. In 1939, he joined the Army Air Corps and was selected for air cadet training, but was dismissed before graduation from flight school. He moved to Los Angeles after being dropped from flight school and was working at Douglas Aircraft when he became interested in flying for the Royal Air Force (RAF), who were at that time recruiting Americans to fight the Germans.

The Americans would fly Hurricanes and Spitfires against the Luftwaffe. In time, he was promoted to flight lieutenant, and given command of No. 71 Squadron.

He was assigned to the 4th Fighter Group as the executive officer and as a major. Later he would be promoted to colonel at the age of 23, and became the youngest colonel in the USAAF. When Peterson first joined the 4th Fighter Group, they were assigned the P-47 Thunderbolt, which was a radical change from the Spitfires the Eagle Squadron pilots had flown.
