# Bach Mai Airfield

Bach Mai Airfield (Vietnamese: Sân bay Bach Mai) is a disused military airport in Thanh Xuan District, Hanoi, Vietnam, located along modern-day Le Trong Tan street. It was constructed by the French in 1917 and used by French forces until 1954; along with Gia Lam Airbase, it was one of the major logistics bases supporting French operations at Dien Bien Phu. After 1954, it was used by the Vietnamese People's Air Force and served as their air defense command and control center during the Second Indochina War, playing a part in the Cambodian–Vietnamese War as well. It is now the site of the Vietnam People's Air Force Museum, where a number of period military aircraft are on display.

## 1918-1940

In 1918 the 1st Escadrille d'Indochine moved to Bach Mai.
In 1939 the unit was redesignated le Groupe Mixte Aérien 595 formed of L'escadrille d'observation 1/595 with the Potez 25 and an escadrille de chasse 2/595 with the Morane-Saulnier M.S.406.

These units saw action in the Franco-Thai War of 1940–41.
Following the Japanese Invasion of French Indochina in September 1940 the remaining aircraft were formed into the Groupement Aérien Nord Indochine, but this was dissolved in March 1943 due to wear and tear and lack of spare parts. During the Japanese coup d'état in French Indochina all remaining French aircraft were destroyed.

## Second Indochina War, 1964-1973

Bach Mai Airfield was used as the air defense command and control center for the Vietnamese People's Air Force during the Second Indochina War. Due to its location in the restricted area of a radius of 30 nautical miles (reduced to 10 in 1967) from the center of Hanoi and its proximity to the Bach Mai Hospital 1 km away, Bach Mai Airfield was off limits to US bombers during the early years of Operation Rolling Thunder with the result that North Vietnamese command and control was generally unmolested. Presidential approval was required for an attack on the airfield and it was attacked for the first time by F-105 Thunderchiefs of the 388th Fighter Wing on 17 November 1967. Bombing restrictions were lifted during Operation Linebacker I and the airfield was attacked on 16 May 1972. On 21 December 1972 in Operation Linebacker II, 2 B-52D's were lost to SA-2 missiles while attacking the airfield. On 22 December 1972 a string of bombs missed Bach Mai Airfield and instead hit Bach Mai Hospital killing 28 hospital staff.
