The base appears to have been initially used to support Operation Junction City in February–May 1967.
The base was established in 1967 on the site of a former French rubber plantation and was located approximately 6 km east of An Lộc in Bình Long Province.[1]
In July 1969 the 11th Armored Cavalry Regiment moved to Quản Lợi and would remain here until September 1969. The regiment would be based here again from December 1969 to July 1970, during which time it participated in the Cambodian Incursion.[2]: 131
The ARVN took over the base and at the start of the Battle of An Lộc in April 1972 it was defended by a battalion of the 7th Regiment, 5th Division[4] and was also the base for the 9th Regiment.[4]: 55 A combined 105mm and 155mm artillery battery was also based at Quản Lợi.[4]: 55 On the evening of 7 April elements of the People's Army of Vietnam (PAVN/VC) 9th Division overran Quản Lợi, the 7th Regiment was ordered to destroy their heavy equipment and fall back to An Lộc.[4]: 70 Once captured the PAVN/VC used Quản Lợi as a staging base for units coming in from Cambodia to join the siege of An Lộc[4]: 91 and key members of COSVN were based there to oversee the battle.[4]: 119
On 8 August the ARVN 18th Division launched an assault to retake Quản Lợi but were stopped by the PAVN/VC in the base's reinforced concrete bunkers. A further attack was launched on 9 August with limited gains and attacks on the base continued for the next 2 weeks eventually gaining one third of the base.[4]: 198 The ARVN finally attacked the PAVN/VC occupied bunkers with TOW missiles and M-202 rockets and this broke the PAVN/VC defense forcing the remaining defenders to flee the base.[4]: 201
Current use
The base is largely overgrown but a small area appears to remain in use by the PAVN.
In November 2022 Bình Phước Province announced plans to redevelop the Quản Lợi military airport into a 350-hectare special-purpose airport.[5]
