When the Apollo program was ended there were a lot of spare F-1s sitting around. I had a general inventory list of F-1 equipment years ago (may still have it buried somewhere). I believe that there were at least 30 complete F-1 engines at the end of the program.
I just finished reading Kraemer's "Rocketdyne" history. The author mentioned that Rocketdyne delivered 98 "flight-rated" F-1 engines to NASA in total. ... - Ed Kyle
A look at Alan Lawrie's wonderful "Saturn" book provides some more information on the F-1 history.
I have no idea. How long has that one been on display?The ones I saw at Michoud were pristine, still in plastic wrapping from back when they were produced.By the way, I think that the main museum has at least two, not one, but I'd have to go there again and look.When the Apollo program was ended there were a lot of spare F-1s sitting around. I had a general inventory list of F-1 equipment years ago (may still have it buried somewhere). I believe that there were at least 30 complete F-1 engines at the end of the program. Some of these had been converted to F-1A status. The list I got was when I wrote to Rocketdyne in the early 1990s. They wanted an opportunity to put the engine back in production, so they had put together a package indicating how much hardware and blueprints had been saved. Whenever someone says that the Saturn V "blueprints" were "destroyed by NASA" at the end of the program is wrong. The agency, and several key contractors, saved the key material because they hoped to someday put the rocket back into production.
On the CD at the back of the book is a spreadsheet listing of all the F-1 engines and their histories.
Right, and good stuff it is. Here is a partial list derived from Lawrie's table.Production F-1 Engine Locations (Last Reported) "Saturn", Alan Lawrie with Robert Godwin, Apogee Books, 2005Last two serial number digits indicate delivery sequence.F-1001 was first production F-1 engine, delivered in 1963. F-6098 was last production F-1, delivered in 1969.Serial numbers not listed below were flown engines (see Lawrie for complete list).Mockup F-1 engines were also manufactured. Some of those are also on display on S-IC-D, S-IC-D, and in museums, etc.Production F-1 Engines On Stage DisplaysS-IC-D at ASRC: F-2003, F-2007S-IC-T at KSC: F-2008, F-2010S-IC-14 at JSC: F-6085, F-6086, F-6089, F-6092, F-6093S-IC-15 at MAF: F-6060, F-6066, F-6091, F-6097, F-6098 Production F-1 Engines Displayed or Stored Separately (Listed "Final Dispositions")Smithsonian: F-1001Canoga Park: F-2004, F-2006, F-3014, F-5037, F-5039MSFC: F-2005, F-2009, F-5038 MAF: F-4023, F-5036, F-6049, F-6090 ASRC: F-4028 EFL: F-6045Alamogordo: F-6067 Scrapped Production F-1 EnginesF-1002, F-6070, F-6072 - Ed Kyle
For JSC, your list is showing only five; see my photos taken at RocketPark and you can see there's six F-1 at this location. BTW, excellentdata from a historical point of view.
Beware mock ups! There is a mock up F-1 outside Rocketdyne's Canoga Park facility. Also a mock up J-2 in the Science Museum in Munich. The F-1 that was outside Building 4200 at MSFC is F-5036 that was originally on the Apollo 10 first stage. It is currently being refurbished.
OK, all you F-1 geeks.Big question for you, that might also help define which F-1's are where.The original F-1's had "straight" Fuel lines from the turbopump to the main valves. There are pics with these engines firing on the test stand.Somewhere in the program both fuel lines ended up with a downward "loop". First the short one and then both lines. (The KSC S-1C engines have one straight fuel line and one looped if you check the pics) Eventually, in later models, both lines looped. Most of the stand-alone museum engines have both loops, which makes sense since they were probably later versions.I'm pretty sure I know "why" they loop, it has to do with valve timing and simplifying the start up and shutdown sequences. These engines were a work of art not only in fabrication but in operation, as simple and fail-safe as possible. Start-up worked with a simple "power up" and normal shutdown with a "power off", no big deal. It was all a matter of pressures building and dropping causing valve timing via hydraulics. (Hence the high cost)My questions are:1a) Which F-1 engine versions have straight; one each; or both looped lines? 1b) And where?2) Do all of the fake engines exhibit the straight lines, or are some of them of the later versions? (These tend to have very fake electrical lines, if any, BTW)3) Which S-1C's launched with which versions?4) What distinguished/identified the F-1A versions?I thought about figuring it out by the pics available, but you guys are so far ahead of me I thought you would might know pretty quickly.Thanks!
Way back in 1990 I visited Rockedyne in Canoga Park. They had an F1 engine in their parking lot, exposed to the elements. I do not know if it is still there.

It is estimated that engine 115-4, the F-1A task assignment engine, couldbe assembled and made ready for testing 10 months after reactivation"Go Ahead."R-
