caption_attribution_description: English: Apollo Lunar Module 2 (LM-2) at the National Air and Space Museum, Washington, D.C. It was built for orbital testing, but was never used.
context_page_description: Several planned missions of the Apollo crewed Moon landing program of the 1960s and 1970s were canceled for a variety of reasons, including changes in technical direction, the Apollo 1 fire, hardware delays, and budget limitations. After the landing by Apollo 12, Apollo 20, which would have been the final crewed mission to the Moon, was canceled to allow Skylab to launch as a "dry workshop". The next two missions, Apollos 18 and 19, were later canceled after the Apollo 13 incident and further budget cuts. Two Skylab missions also ended up being canceled. Two complete Saturn Vs ended up going unused and are currently on display in the United States.
context_section_description: Two complete Saturn Vs went unused after the Apollo program, SA-514 and SA-515, as well as the third stage of the SA-513. SA-513 was the launch vehicle originally planned for the Apollo 18 mission, which was instead used (without its third stage) to launch Skylab.
  A Saturn V on display at the Johnson Space Center is made up of the first stage of SA-514, the second stage of SA-515, and the third stage of SA-513. This display includes a production command/service module (CSM-115) which was never completed after funding was cut.
  A Saturn V on display at the Kennedy Space Center Visitor Complex is made up of static test stage S-IC-T and the second and third stages of SA-514. The command module associated with the KSC Saturn V display is a boilerplate, BP-30. The stack was originally displayed outdoors in front of the Vehicle Assembly Building and was a stop for tour buses. It was later restored and moved indoors to the Apollo/Saturn V Center.
  The first stage from SA-515 resides at the INFINITY Science Center in Pearlington, Mississippi. The third stage was converted into a backup to the Skylab space station. It is now on display at the National Air and Space Museum.
  Several Saturn IBs also remained unused and in storage at the end of the Apollo program.  Three (SA-206, SA-207 and SA-208) were used for the manned launches of the Skylab program, and SA-210 was used for the manned ASTP flight. The second stage of SA-212 was rebuilt as the launched Skylab.  Of the remaining vehicles, two are on display, and the rest were scrapped.   Any surplus Rocketdyne H-1 first stage engines were rebranded as the Rocketdyne RS-27 engine for usage on active launch vehicles of the time, such as those of the Delta 2000 Series in 1974.
  The last complete, unflown Saturn IB, SA-209, kept on standby for a possible Skylab Rescue mission, is on display outdoors in the Rocket Garden of the Kennedy Space Center Visitor Complex, topped by an Apollo boilerplate in place of the rescue spacecraft.
  One other surplus Saturn IB (SA-211) was displayed horizontally for a time, until the late 1970's, at the Marshall Spaceflight Center, in Huntsville, Alabama.  The second stage of the vehicle (S-IVB-211) was later moved to be combined with the Neutral Buoyancy training components of Skylab at the US Space and Rocket center, minus it's J-2 engine.  The first stage of SA-211 (S-1B-11) is now displayed vertically at the welcome center off of Interstate I-65, near to Ardmore, Alabama.  That vehicle hosts an older ground-test second stage (Battleship stage?) SLA adapter and boilerplate Apollo hardware.
  The first stage of SA-212 (S-IB-12) was the last stage to have been static test fired, but was later scrapped, since no further flights were planned.  The second stage of SA-212 (S-IVB-212) was converted into the flown, prime Skylab space station.
  The remaining surplus Saturn IB first stages for SA-213 and SA-214 were built, but never static tested, and were also scrapped.  No S-IVB second stages were ever built for these two vehicles.
  Likewise, the canceled flights' CSMs and LMs went either unused or were used for other missions:
  After Apollo 15's original H mission was canceled, there was a surplus H mission CSM and Lunar Module. CSM-111 was used for the Apollo–Soyuz Test Project. LM-9 is on display at the Kennedy Space Center (Apollo/Saturn V Center)
  Apollo 18's CSM and LM were used by Apollo 17.
  Apollo 19's CSM (#115) is displayed on the Saturn V located at the Johnson Space Center. Its LM (LM-13, originally assigned to Apollo 18) was only partially completed by Grumman, and was used as a prop for the 1998 HBO miniseries From the Earth to the Moon in Moon exploration scenes. It is now on display at the Cradle of Aviation Museum on New York's Long Island.
  Apollo 20's CSM was never completed and was scrapped. The LM was also scrapped before completion, though there are some unconfirmed reports that some parts (in addition to parts from the LM test vehicle LTA-3) are included in the LM on display at the Franklin Institute in Philadelphia, Pennsylvania.
