Its three stages duplicated the flight configuration, ordnance, and umbilical connections of their live counterparts. Although inert, the retrograde rockets, ullage rockets, and shaped charges had the dimensions of the live ordnance to let the launch team practice ordnance installation.^[3] The first stage only had one real F-1 engine, and the inter-tank section of the first stage had a different paint scheme than flight vehicles. The third stage had a paint scheme partially matching the Saturn 1B, for which it was originally made.

SA-500F was first stacked on Mobile Launcher 1 in the Vehicle Assembly Building High Bay 1 up to the Instrument Unit on March 30, 1966. The Apollo Command/Service Module facilities verification boilerplate was added on May 2, 1966.^[4]

500F was rolled out to Pad A on May 25, 1966. On June 8, it was rolled back to the VAB temporarily as Hurricane Alma passed, though the ground crew supposed the rollback was more of an exercise than necessity because winds remained below critical for the entire storm.^[5] 500F returned to Pad A on June 10.^[6] Facility checkout culminated with a "wet test" (Filling the tanks with propellant)to verify storage and transfer of propellants.^[3]

500F was removed from Pad A on October 14 and destacked on October 21, 1966.^[6]

Paint scheme

SA-500F was the first complete assembly of something resembling a Saturn V, and model makers quickly patterned their designs after its paint scheme, but engineers changed the black stripe to white in the intertank section of the first stage for flight vehicles after discovering the intertank got too hot from the heat of the Sun. The third stage's paint scheme is similar to that of the Saturn IB, with some minor differences, since it was originally made for testing the facilities of the Saturn IB. Model manufacturers largely haven't updated their paint schemes since.^[9][10] The SA-500D test article also had a similar paint scheme.

Fate

The first stage, S-1C-F, was returned to the Marshall Space Flight Center and was stored there for an extended time (possibly for a few years). The stage was eventually scrapped to make more room.^[12]

The second stage, S-IIC-F, was reassigned as a dynamic test stage at Marshall in early 1967 as S-II-F/D for use in the dynamic test vehicle SA-500D, after its predecessor was destroyed in an accident on a test stand. It is now displayed as part of the Saturn V at the U.S. Space & Rocket Center.^[12]

The third stage, S-IV-B-500F, was manufactured as a dummy third stage for the smaller Saturn IB and was used to fit-check the two Saturn IB launch complex facilities (LC 34 and LC 37). It was then modified to meet the Saturn V third stage configuration for use on the SA-500F. In 1970, it was modified into the Skylab Workshop Dynamic Test Stage^[1] and was shipped in December to the Johnson Space Center for dynamic testing. In June 1971, it was shipped to Marshall for Skylab workshop static testing; and in June 1974 it was returned to KSC.^[15] It was scrapped in the 1980s or 1990s, with a possible sighting in 1986.^[2]
