Pyotr Ivanovich Pumpur (, ; 25 April 1900 – 23 March 1942) was a Soviet Air Forces fighter pilot, Hero of the Soviet Union, and lieutenant general of Latvian ethnicity.

Pumpur joined the Red Army in 1918 and became a mechanic and driver in its fledgling air service due to his civilian mechanical and driving experience. After the end of the Russian Civil War he became one of the first to graduate from newly established flight schools and served as a fighter pilot during the interwar period, rising to command a fighter brigade in the mid-1930s. Between 1936 and 1937, he commanded the Soviet aviation group assisting the Spanish Republican Air Force during the Spanish Civil War, claiming five victories. For his actions, Pumpur was made a Hero of the Soviet Union, and promoted to the rank of Komkor, skipping one grade, upon his return to the Soviet Union.

Early life and Russian Civil War

Pumpur was born on 25 April 1900 in Plātere Parish in Kreis Riga, Russian Empire to a peasant family. He graduated from the parish school and helped his father in working for their more prosperous neighbors, then studied at a vocational school for two years. Using the knowledge he gained, Pumpur became an apprentice mechanic and an assistant chauffeur before joining the Red Army in May 1918. Due to his work as a mechanic and with cars, he was sent to the 4th Fighter Aviation Detachment in Moscow, serving as an assistant chauffeur. In October, Pumpur was transferred to the 2nd Pskov Fighter Aviation Detachment in Samara, again serving in the same position.

In 1919, Pumpur became a member of the Communist Party.

Interwar period

After the Civil War ended, Pumpur remained in the army, serving as an aircraft mechanic with the Commandant's Headquarters of the Central Aerodrome in Moscow from July to December 1921. After constantly interacting with pilots, listening to their conversations and stories, he requested to receive flight training. Pumpur received initial training at the Yegoryevsk Military-Theoretical School for Pilots between January 1922 and March 1923. In April, he began flight training at the 2nd Military School of Pilots at Borisoglebsk, graduating with the first class of cadets on 26 October. Among his ten classmates was future aviation pioneer Valery Chkalov. From November to May 1924 Pumpur continued to master flying techniques at the 1st Military School of Pilots in Moscow, and studied at the Higher Military Aviation School of Gunners and Bombardiers in Serpukhov from May to July.

After graduation, in August 1924, Pumpur was assigned to the 2nd Fighter Aviation Squadron in Moscow, where he served as a junior pilot and then a senior pilot, mastering all types of aircraft flown by the unit. In July 1925, the squadron was involved in the suppression of a Menshevik and Socialist Revolutionary-backed revolt near the Illinsky Station of the Moscow–Kursk Railway, using its planes to conduct reconnaissance. In October of that year Pumpur became a flight leader, and in December 1926 the 2nd Squadron was renamed the 7th Separate Fighter Aviation Squadron. He led a separate detachment of the squadron from February 1927. In 1929, Pumpur graduated from advanced courses for Air Force commanders at the Zhukovsky Air Force Academy. He took command of the 17th Aviation Squadron in September 1930, simultaneously serving as its commissar from February 1931, and was subsequently transferred to command the 31st Fighter Aviation Squadron. From June 1934, he was commander and commissar of the 403rd Fighter Aviation Brigade. On 4 December 1935, after the Red Army created personal military ranks, Pumpur was made a Kombrig. In February 1936, Pumpur became a student at the operational faculty of the Zhukovsky Academy.
