This Provider was taken on charge in 1957 as a C-123B and served in Vietnam from 1961 to 1972, first as a UC-123B and later as a UC-123K when the auxiliary J85 jets were added, flying low-level defoliant and insecticide spray missions and cargo deliveries into strips as short as 2,000ft. Stored at Davis-Monthan from 1976 but reactivated for the Peruvian police on drug interdiction work under US Department of State registration N97033 from 1987 (nicknamed "El Burro"), prior to preservation at Dover in 1990. Serial presentation "AF40-658" is of course nonsense and should have read "AF54-658".
