Unflown or Test Hardware - John Duncan

SA-513: Apollo 18, (Cancelled)

Launch vehicle serial numbers: S-IC-13, S-II-13, S-IVB-513, S-IU-513

Spacecraft serial numbers: None

Disposition of Hardware:

• S-IC-13 used for Skylab I launch

• S-II-13 used for Skylab I launch

• S-IVB-513 on display at Johnson Space Center

• S-IU-513 used for Skylab I launch

NOTE: When Apollo 15 was deleted and Apollos 16-18 renumbered, it left Launch Vehicle SA 513 for Skylab. S-IVB-212 had already been pulled from production and modified into the Orbital Workshop, with S-IVB-515 as the backup workshop. S-IVB-513 had already been completed (and would require too much work to convert it into the workshop configuration) so it became an "extra" stage.


SA-514: Apollo 19, (Cancelled)

Launch vehicle serial numbers: S-IC-14, S-II-14, S-IVB-514, S-IU-514

Spacecraft serial numbers: None

Disposition of Hardware: • S-IC-14 on display at Johnson Space Center

• S-II-14 on display at Apollo-Saturn V Center, Kennedy Space Center

• S-IVB-514 on display at Apollo-Saturn V Center, Kennedy Space Center

• S-IU-514 location unknown

NOTE: This vehicle, along with Skylab II (S-IVB-515) could have been our second space station and might have survived until the Space Shuttle flew.


SA-515 Apollo 20 (Cancelled)

Launch vehicle serial numbers: S-IC-15, S-II-15, S-IVB-515, S-IU-515

Spacecraft serial numbers: None

Disposition of hardware: • S-IC-15 on display at Michoud Assembly Facility

• S-II-15 on display at Johnson Space Center

• S-IVB-515 converted into Skylab Orbital Workshop backup hardware, now on display at the National Air and Space Museum

• S-IU-515 location unknown


NON-FLIGHT HARDWARE

SA-500F Facilities Integration Vehicle

Launch vehicle serial numbers: S-IC-F, S-II-F, S-IVB-500F, S-IU-500F

Spacecraft serial numbers: S/C FVV

Rolled out as completed Saturn V stack on ML #1 on May 25, 1966.

• S-IC-F: One F-1 engine and four mass simulators were installed, No American Flag painted on LOX tank, manufactured at Michoud, location unknown (last seen at MSFC)

• S-II-F: (S-II-F/D) S-IC/S-II interstage separation planes painted red, 8 ullage rockets installed, no vertical motion targets, 8 camera targets on Fwd Skirt, on display as second stage of the Saturn V at the Alabama Space and Rocket Center, Huntsville, AL (Used as Dynamic Test Stage replacement after destruction of S-II-S/D and S-II-T)

• S-IVB-500F: (Also known as S-IVB-200F) Motion Damper Arm mounted on the S-II/S-IVB interstage (moved to Launch Escape Tower on subsequent vehicles), S-II retrorocket fairings painted red (white on subsequent vehicles). Paint scheme is a modified 200 series (Saturn IB) S-IVB type. Location unknown

• S-IU-200F/500F -- also used with S-IVB-200F/500F for verifying Pad 34, built at MSFC, location unknown

• S/C FVV: Spacecraft Facilities Verification Vehicle- Apollo Boilerplate SLA/CSM/LES (serial unknown), now part of Saturn IB SA-209 display at Visitors Complex, KSC (SM had deteriorated and was replaced with new mock-up in 1993)

Comments: First complete Saturn V stack used to test ML #1 and Pad A interfaces. Rolled out on ML #1 on May 25, 1966. Most plastic models were patterned after this vehicle's paint and markings scheme which was not correct for any flight vehicle.


 Other Test Stages

• S-IC-T: All systems test stage now on display at the Apollo Saturn V Center, KSC Florida (manufactured at MSFC), now painted to resemble S-IC-6 (Apollo 11).

• S-II-T: Destroyed in an explosion while being tested May 28, 1966

• S-IC-D: Dynamic Test Stage at MSFC with four simulated and one real F-1 engines. On display at Alabama Space and Rocket Center.

• S-II-D: Cancelled, S-II-S/D used instead

• S-IVB-D: Dynamic Test Stage- on display at the Alabama Space and Rocket Center

• S-IU-D: Location unknown

• S-IC-S: Structural Test Stage, no engines installed, location unknown

• S-II-S/D: Structural and Dynamic Test Vehicle at MSFC, destroyed in test stand September 29, 1965, S-II-F/D used instead (see 500-F above)

• S-IVB-S: Cancelled

• S-IC-C: Wooden mockup built at MSFC to map wiring harness length, location unknown

• S-IC battleship stages: location unknown

• S-IC Thrust structure mockup: built at Michoud, location unknown

• S-IC Thrust structure mockup: located at the old fairgrounds in New York, site of the 1964 World's Fair (seen in movie "Men in Black")Photo courtesy of Rick Sternbach
