This Provider was one of the occupants of AMARC's "Celebrity Row" in 1987. It had been used on Operation Ranch Hand during the Vietnam War. This involved using aircraft to spray an estimated 20 million U.S. gallons (76,000 m3) of defoliants and herbicides over rural areas of South Vietnam in an attempt to deprive the Viet Cong of food and vegetation cover.

This Provider on display at the National Museum of the USAF was accepted by the USAF in 1957 and saw extensive service in Vietnam as a 'Ranch Hand' sprayer (possibly the most ill-conceived and reckless program ever devised by the USAF). The aircraft took almost 600 hits in combat so was named 'Patches' for the damage repairs that covered it. In addition, seven of its crew received the Purple Heart for wounds received in the line of duty.

Delivered to USAF as a C-123B and later converted to a C-123K. To MASDC for storage in July 1982. To the museum for display in October 1990

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".
