This list was originally based in part on information from Siloman's list His site, www.siloworld.net, has lots of good information and stories about missile sites In particular, a nice photo layout of the various US ICBMs is at http://www.siloworld.net/ICBM/SYSTEMS.htm.
Another interesting web site is missilebases.com which is best described as a real estate service for old missile sites. This is owned/run by Edward Peden who owns an Atlas E site (#6) near Dover, Kansas, where he lives (and formerly manufactured ultralight aircraft). There have been many articles written about Ed and his home. Some include:
Another real estate site is silohome.com which seems to be dedicated to selling Plattsburgh site 8. They claimed to have been successful via eBay at 2.1 million dollars with the sale to be completed in April or May 2003, but as of April 2010 it's still for sale, for 2.3 million dollars.
Another real estate site is http://www.siloforsale.com. Checking on February 18, 2009, they have two properties for sale: an Atlas F (577-2 in Oklahoma) and a Titan II (373-9 in Arkansas). As of April 2010, they only list the Atlas F site. After about July 2011 the site appears to have died, one last copy is at http://web.archive.org/web/20110721192613/http://www.siloforsale.com/availableproperties.htm.
Yet another real estate site is http://undergroundfortresses.com though it looks like the site has not been updated for several years.
Microsoft's MSR Maps (formerly Terraserver-USA, see https://en.wikipedia.org/wiki/Microsoft_Research_Maps) used to be helpful in finding photographs of just about any location. I included URLs for sites I had located on MSR Maps. In April 2012 I found out that Microsoft planned to shut down MSR Maps but it continued for several years before finally going away. Links were rewritten to use Google Maps imagery but I'll keep the older USGS images from MSR Maps as historical reference. This is particularly interesting for retired missile fields because the older USGS photos that MSR Maps provided can be compared with newer Google imagery and in some cases you can see how facilities have been recycled or obliterated. Note that Google Maps can be a real resource hog when loading images.
Google Maps is a web site that provides aerial photos as well as maps.
Google Earth is also quite popular though it requires downloading extra software to work. I have to say that some of the photography is miserable in places, but excellent in others, probably just a matter of availability and cost. There was a placemark file that purported to list all ICBM sites via Google Earth, see http://bbs.keyhole.com/ubb/showthreaded.php/Cat/0/Number/187519/an/page/page/0/vc/1 except that it has been removed.
Other mapping/photo web sites include:
The Topeka Capital-Journal had an interactive map of Kansas sites, namely Atlas E sites around Topeka, Atlas F around Salina, and Titan II around Witicha. But that web page disappeared, try http://web.archive.org/web/20080319103803/http://www.cjonline.com/webindepth/missilesilos/multimedia/map.shtml. There are a few factual errors, for example claiming 17 Titan II silos (there were 18) while the map shows the location of 16, and showing only 9 of 12 Atlas F silos.
A good list of Air Force bases is here, compiled by Joe McCusker. It's been especially useful for determining the closing date of former bases.
Another list of Air Force facilities is at http://www.globalsecurity.org/wmd/facility/usaf.htm.
Former military bases are remembered at http://www.formerbases.com.
Another good site is Scott D. Murdock's http://www.airforcebase.net. His trip reports are particularly interesting to me because they locate some sites that are not easily found, include images, and sometimes tell interesting tales.
Another missile fan's web site is http://minutemanmissile.com which is largely about Minuteman but also has material on ABM and SICBM systems.
A 607-page government publication, "To Defend and Deter: Legacy of the United States Cold War Missile Program" was available at: http://www.cevp.com/docs/COLDWAR/1996-11-01952.pdf but has since disappeared. I found another copy at https://www.denix.osd.mil/denix/Public/Library/NCR/coldwar.html but that went away too, and a Google search only reveals sources that will sell you a copy; printed copies occasionally show up on eBay. Another copy was found at https://www.denix.osd.mil/portal/page/portal/content/environment/CR/HistoricBuildingsandStructures/DocumentationGuidance/94-1264-LEGACY-US-COLD-WAR-MISSLE-PROGRAM_0.PDF which also disappeared, but lately you can try http://www.denix.osd.mil/cr/upload/94-1264-LEGACY-US-COLD-WAR-MISSLE-PROGRAM_0.PDF so, hopefully this will stick around for a while, just be aware it is around 36 megabytes in size. I also kept a 70-megabyte copy and as far as I know there are no copyright issues, having been published/funded by the US government: 1996-11-01952.pdf.
Scott O'Steen had a web site Silo-Net with drawings and other information on Atlas and Titan systems/sites and many more links to other web sites. The web site disappeared many years ago, however, pieces may be viewable at http://web.archive.org/web/20011205013801/http://www.ruralnet.net/~scotto/index.html.
spaceflightnow.com carries news on space-related events, including a fairly good list of upcoming launches.
A nice table of ICBM deployments from the Natural Resources Defense Council (NRDC) is here.
Another nice discussion of ICBM history is http://www.losangeles.af.mil/shared/media/document/AFD-060912-023.pdf.
Yet another ICBM history is at http://fas.org/nuke/guide/usa/icbm/.
The Washington Post ran an article partly about South Dakota Minuteman sites D-1 and D-9 but it was really a retrospective of the Cold War, entitled "Rethinking the Unthinkable" by Bob Thompson, published July 28, 2002; see https://www.washingtonpost.com/archive/lifestyle/magazine/2002/07/28/rethinking-the-unthinkable/c204de2a-d8ef-4a07-820e-f46aa2e228de/.
The Nuclear Weapons Cost Study Project has a nice photo gallery. For the more serious reader, their main web page here seems extensive.
Terry Naughton was a Convair safety inspector and wrote about his experiences here. However, the link died, but was archived at http://web.archive.org/web/20031219073902/http://www.jump.net/~crossley/AtlasE/Naughton/iwt1.html. His other writings are currently at http://people.redhat.com/zaitcev/avia/scav.html, scroll down or search for Atlas to find the relevant parts which I believe are the same as the previous link.
Strategic Air Command web site: http://strategic-air-command.com.
Patches: sacpatches.com (which died in August, 2007, see http://web.archive.org/web/20070704193348/http://www.sacpatches.com for a farewell message, though the old contents are in archive.org, see http://web.archive.org/web/20070519035902/http://www.sacpatches.com), http://strategic-air-command.com, http://usafpatches.com.
http://www.afhra.af.mil is an official Air Force historical resource, in this case I'm more interested in Organizational Records (Wings/Groups and Squadrons/Flights) but other folks might find other areas helpful.
An extensive list of U.S. Nuclear accidents is at http://www.lutins.org/nukes.html. A discussion of nuclear accidents is at http://usgovinfo.about.com/library/weekly/aa081600a.htm and DOD policy on handling a nuclear accident is at http://usgovinfo.about.com/bldod523016.htm. Another discussion is at http://nsarchive.wordpress.com/2010/04/02/document-friday-narrative-summaries-of-accidents-involving-nuclear-weapons (now gone, try https://web.archive.org/web/20130130155615/http://nsarchive.wordpress.com/2010/04/02/document-friday-narrative-summaries-of-accidents-involving-nuclear-weapons) which in turn references http://nsarchive.files.wordpress.com/2010/04/635.pdf.
An extensive web site discussing nuclear weapons is http://nuclearweaponarchive.org. Lists of tests, photos, etcetera.
http://www.astronautix.com A comprehensive history of space flight, also billed as the "Encyclopedia Astronautica."
A "Field Guide" to American spacecraft is interesting and sort of related to ICBMs because the Mercury and Gemini programs used modified ICBMs. See http://www.americanspacecraft.com.
Jonathan's Space Home Page, http://www.planet4589.org/space, deals with space flight and may yield information related in some way to ICBMs. For example his page http://www.planet4589.org/space/lvdb/launch/Atlas is a list of all Atlas launches. And he, too, has a comprehensive list of launch sites though I have not yet tried to reconcile his list with mine; see http://planet4589.org/space/log/sites.txt.
http://www.radomes.org/museum is a site dedicated to air defense radars.
http://www.scramble.nl/usafbase.htm allows searching for info on aircraft and missiles by serial number. Fairly limited search capabilities last I checked.
http://home.att.net/~jbaugher/usafserials.html is another serial number database though current location isn't included. Also, the web site has gone away, try http://web.archive.org/web/20080512044756/http://home.att.net/~jbaugher/usafserials.html.
http://www.sscnet.ucla.edu/polisci/faculty/boneill/trivia.html An interesting quiz/trivia about missiles.

http://www.mercenary-missileer.com Initially supplied patches, then branched out to an interesting line of missile-related products, and now a discussion forum as well.
http://www.nukephoto.com Impressive collection of photos, largely based on work by Paul Shambroom for his book, Face to Face with the Bomb: Nuclear Reality After the Cold War. The web site has died, so try: http://web.archive.org/web/20071230063941/http://www.nukephoto.com.
http://en.wikipedia.org/wiki/Intercontinental_ballistic_missile Wikipedia's entry for ICBMs.
http://cryptome.org/eyeball/index.org is a large collection of imagery of mostly-military stuff.
Kansas had a variety of missiles; a short article (from 1998) about them and one man's start at preserving their history is at http://www.cjonline.com/stories/020998/com_missile.html. Unfortunately, the National Aerospace Trust apparently no longer exists. A collection of their Atlas photos is at http://siloboy.com/site/Pages/oppPix.html. A Titan II document of theirs is at http://www.308smw.com/files/Titan_II_Phase_II_Construction_Prints_LRAFB.pdf which is a collection of blueprints.
http://www.environmentalgraffiti.com/news-most-incredible-abandoned-missile-bases-earth "10 Creepiest Abandoned Cold War Missile Silos" is an interesting collection of photographs.
http://www.alternatewars.com/WW3/WW3_Documents/USAF/SAC_MSL_CHRON_1939-88.htm is an extensive SAC missile chronology from 1939-1988.
http://www.ucsusa.org/nuclear_weapons_and_global_security/nuclear_weapons/technical_issues/nuclear-weapons-complex-map.html offers a Google Earth overlay detailing nuclear weapons sites.
http://www.captainswoop.com/icbm/map1.html is another missile fan's web site.
Museums and other visitable facilities include:
There's a Yahoo group called missile_talk, see http://groups.yahoo.com/group/missile_talk/.
Another group is http://www.missileforums.com which includes news, a store, and discussion forums. It actually seems to be an offshoot of http://www.mercenary-missileer.com mentioned earlier.
NASA has an archive site for some of their best images, GReat Images in NASA, or "GRIN", at http://grin.hq.nasa.gov.
An enjoyable history of liquid-fuel rocket development is the book "Ignition! An informal history of liquid rocket propellants" by John D. Clark (1972), but it is hard to find and terribly expensive to purchase.
"Ballistic Missiles in the United States Air Force 1945-1960" by Jacob Neufeld is an official Air Force history book (400 pages) that is somewhat interesting but contains a lot of the history of the bureaucracy of the various programs. It does contain some good photos, and tables of development/deployment dates.
"A History of the U.S. Air Force Ballistic Missile" by Ernest G. Schwiebert is similar to Neufeld's book but covers 1954 to 1964.
"The Effects of Nuclear Weapons" by Samuel Glasstone. This is a classic of sorts, originally published around 1957.
"From Snark to Peacekeeper: a pictorial history of Strategic Air Command" is a good book because it not only contains many good photos (as the title implies) but it also contains maps for all US ICBM sites, some of which have been reproduced in various web sites. Be warned the maps are not always exactly right.
So what do people do with old missile sites? As indicated above, some are turned into homes or schools. At least two are used for scuba diving. I heard one is used as a "shot tower" to manufacture lead shot for ammunition but I've never been able to confirm this. Several were used as hazardous storage facilities. A few have become museums with (hopefully) more to follow. One was used as a dark sky site by the Prairie Astronomy Club. As of 2003 a few are becoming internet data storage services. One was a "time capsule" repository but the project is no longer available.
Here is a fascinating sound clip from an Air Force training film that describes how missile guidance systems work (it's a 1.1 Meg .wav file). We think this is for the cruise missile. A transcription is here if you have difficulty understanding the sound clip. Also other related items such as the Retroencabulator from Rockwell.
Bureau of Atomic Tourism but the web site has died and been re-assigned, try https://web.archive.org/web/20100206122824/http://www.atomictourist.com/ instead. Visit the Trinity site and more.
Roswell-online was an interesting site many years ago but it has died and been taken over by a German storage-systems company.
http://www.casde.unl.edu Virtual Nebraska might be an alternate source for imagery of Nebraska launch complexes.
On June 6, 2008, it was announced that the three ICBM Space Wings will be renamed as Missile Wings. This may cause various Web links to fail as URLs change, and a few patches will need to be redesigned and deployed.
TITAN I sites
TITAN II sites
Miscellaneous other sites (Not much there yet)
Vandenberg Air Force Base A lot of overlap with the above and more that's not.
Hill Air Force Base (Skeletal)
Chanute Air Force Base (Skeletal)
Anti-Ballistic-Missile stuff Hey, as long as we're talking about ballistic missiles, why not some ABM stuff to go with it.
