Phạm Tuân

Phạm Tuân was born in Quốc Tuấn, Thai Binh province in northern Vietnam. He joined the VPAF, or Vietnam People's Air Force (North Vietnamese Air Force) in 1965, was later commissioned as a combat officer. He flew interceptor missions in a MiG-21 jet fighter against United States aircraft during the Vietnam War.

On the night of 27 December 1972, during Operation Linebacker II (also referred to as the Christmas Bombings), then-Major Phạm engaged a USAF Strategic Air Command (SAC) B-52 Stratofortress heavy bomber using air-to-air missiles. He reported that his missiles struck the B-52, causing it to go down in flames. This claim, which would be the only B-52 downed in aerial combat, is disputed by U.S. records, which state that this B-52 was downed by a surface-to-air missile, also responsible for all other B-52s shot down during the campaign.[3] In a book named "Hà Nội - Điện Biên Phủ trên không" (Hanoi - the Battle of Dien Bien Phu in the air) by Nguyễn Minh Tâm, published by Nhà xuất bản Quân đội Nhân dân Việt Nam (Viet Nam People's Army Publishing House), the author affirms that Phạm Tuân shot down the B-52 with two K-13 air-to-air missiles within a range of 4 kilometers.[4]

Tuân said that because the B-52 was equipped with a large number of infrared decoys, he had to get close to the target (within 2-3 kilometers) in order to ensure the bomber's destruction, though the minimum safe range for launching missiles is at least 8 kilometers.

Tuân received numerous distinctions for his service, including the Ho Chi Minh Order. He also was awarded the Order of Lenin and the rare honor of being one of the few foreigners to receive the title "Hero of the Soviet Union".

Tuân reached the rank of lieutenant colonel in the VPAF before eventually training to be a research cosmonaut in the joint USSR-Vietnamese space program. On 1 April 1979, he was selected as a member of the sixth international crew for the Interkosmos program. His backup was Bùi Thanh Liêm. Tuân, along with Soviet cosmonaut Viktor Gorbatko, was launched from Baikonur Cosmodrome on 23 July 1980, on board the Soyuz 37 mission to the Salyut 6 space station.

During his time in orbit, Tuân performed experiments on the melting of mineral samples in microgravity. He also carried out plant experiments on azolla and photographed Vietnam from orbit for mapping purposes. Tuân was in space for 7 days, 20 hours, and 42 minutes, completing 142 orbits, and returned to earth on 31 July 1980.

Tuân is married and has two children. He is now a retired lieutenant general, director of the General Department of Defense Industry of the Ministry of Defense, and is a non-elected member of the Vietnam National Assembly.
