The subject of U.S.-made military equipment in active service with Communist Vietnam has fascinated military enthusiasts and analysts alike. For all their fascination however, relatively little has been written about the continued use of U.S. military equipment by unified Vietnam after the fall of South Vietnam in 1975. On the rare occasion that the subject has been covered, most attention has gone towards the operations of captured aircraft like the F-5E, C-130 and UH-1. North Vietnam is estimated to have captured more than 1.100 aircraft and helicopters from the Republic of Vietnam Air Force. Equally significant numbers of armoured fighting vehicles (AFVs) ended up in its hands, some of which to this day still bolster the inventory of the Vietnamese People's Army.
