Vietnam People's Air Force

The Vietnam People's Air Force (VPAF; Không quân nhân dân Việt Nam (KQNDVN)), officially the Air Defence - Air Force Service (ADAF Service; Vietnamese: Quân chủng Phòng không - Không quân (Quân chủng PK-KQ / QC PK-KQ / PKKQ)) or the Vietnam Air Force (Không quân Việt Nam (KQVN)), is the aerial, air and space defence service branch of Vietnam. It is the modern incarnation of the so-called North Vietnamese Air Force (NVAF) and absorbed the South Vietnamese Air Force (RVNAF/VNAF) following the reunification of Vietnam in 1975 and is one of three main branches of the People's Army of Vietnam, which is under the executive administration of the Ministry of National Defence. The main mission of the VPAF is the defence of Vietnamese aerospace and the provision of air and space cover for operations of the People's Army of Vietnam.

The modern VPAF consists of two principle components: the Air Defence (Phòng không, mainly operating air-defence radars, anti-air artillery and missile systems) and the Air Force (Không quân, mainly operating aerial vehicles and military aircraft for combat and transport) that are currently organized as separate divisions under the ADAF Headquarters. From 1977 to 1999, the components were split into two different service branches, before being remerged as the existing unified ADAF Service since 1999, placing both components under a unified leadership to facilitate joint operations.
