The FV438 Swingfire was an armoured anti-tank vehicle of the British Army. It was derived from the FV430 series of vehicles by converting the FV432 to accommodate a launcher for Swingfire anti-tank guided missiles. When it first came into use in the 1970s, the FV438s were operated by specialised anti-tank units of the (British Infantry and Royal Armoured Corp). The role was transferred to the Royal Artillery in the mid 1980s, and the FV438s were taken into service as guided-weapon troops of armoured regiments, nine vehicles to a regiment.
