Peacekeeper (MX) Missile Site Coordinates

Warren Air Force Base had 200 Minuteman missiles (initially Minuteman I, later Minuteman III), but 50 of them (flights P through T) were converted in the late 1980s to the only deployment of Peacekeeper (MX) missiles. This left Warren with a peak of 150 Minuteman III missiles and 50 Peacekeeper missiles but as of mid-September 2005, the Peacekeeper is retired.

Peacekeeper (sometimes called Missile X, thus MX, early on) is a strange name to some for one of the most powerful weapons of mass destruction. But indirectly perhaps it has kept the peace. Another designation is LGM-118A. In the late 1990s there were grumblings of retiring it due to the cost of maintaining two different kinds of land-based ICBMs, coupled with international treaties that reduced the Peacekeeper's advantage of multiple re-entry vehicles. The retirement actually began October 1 2002, partly due to financial concerns and partly due to an arms reduction agreement between the USA and Russia that was signed in 2001. The deactivation, disassembly, and shipment of the missiles back to Hill AFB in Utah took about 17 days per missile and almost three years. The warheads will replace older ones on Minuteman III missiles.

The Peacekeeper was large, with four stages. The first three stages were solid and the fourth was storable liquid (hydrazine and nitrogen tetroxide). Each stage was manufactured by a different contractor. The fourth stage was liquid because it needed to be shut down and restarted many times as it deployed the independently targetable re-entry vehicles. But with arms-reduction treaties cutting the actual weapons down to one per missile, this seemed a moot point unless we wanted to deploy multiple decoys to confuse missile defense systems.

An interesting quirk of fate is that the Peacekeeper launch control facilities used older Minuteman equipment from the 1980s, since that is when the Peacekeeper was emplaced in re-worked Minuteman silos. Later, Minuteman equipment was upgraded but not the Peacekeeper. Thus, old equipment controlled and launched the latest missile, while new equipment is used on the older missiles.

One company, E'prime, has tried to market a Peacekeeper-derived launch vehicle. A significant delay was caused by arms reduction treaties which might have considered it a missile. Though contracts have been slow in coming, they have been contacted by the Missile Defense Agency about using their vehicles as a missile defense system (5/6/2002). See http://www.eprimeaerospace.com and http://www.islandone.org/SpencerAvLeakReports/Avweek-950220.html.

Meanwhile the decommissioned Peacekeepers are being acquired by Orbital Sciences Corporation for use as launch vehicles, which seems to be in direct competition (conflict?) with E'prime, above. See http://www.orbital.com/SpaceLaunch/Minotaur. Another article on re-using Peacekeepers is at http://www.space.com/missionlaunches/050922_peacekeeper_student.html but be warned, that's an ad-intensive web site!

WARNING

Although Peacekeeper missiles have been retired, it appears the Launch Facilities (LFs, i.e. the silos) and probably the alert facilities are still patrolled and trespassers will be detained or worse. I have received email from one such person and decided it was worth including this warning.

The people: the 90th Space Wing (activated July 1 1963), comprised in part of the 90th Operations Group, 90th Logistics Group, the 90th Support Group 90th Medical Group, and the 400th Missile Squadron (which was activated July 1 1964, and is scheduled for deactivation October 4th 2005). Other resources:

Flights are denoted by a letter of the alphabet followed by 1 through 11, with #1 being the Missile Alert Facility (MAF) which consists of an above-ground structure plus an underground Launch Control Center (LCC) staffed by two officers. The Launch Facilities (LFs, i.e. missile silos) are connected to the MAF/LCC by hardened cable systems. For humor, I also include the nicknames given in Nuclear Heartland.

Warren also has two on-base training silos (U-01 for Minuteman III and U-02 for the Peacekeeper) as well as LCC crew training facilities.

Warren sites you can see from Interstate 80 and Interstate 25: OK, you're in a hurry and you don't want to detour but you want to say "I've seen a missile site!" There are a small number that can be seen but not necessarily clearly. K-11 is probably the best.


Around September 2006 it was noticed that the diesel tanks are being removed.

"Little Horse Creek"
As you cruise the countryside you might see a fat wooden post, with a sort of junction box on it near ground level. In fact the two connectors (marked "operate" and "read") are air fittings with standard tire valve stems. I'm guessing the control cables are pressurized (for tamper resistance/detection and/or water elimination) and that these are test/maintenance points. The two large bars on either side are probably to prevent damage from cattle that like to use such posts for scratching. I received the following via email: I'm not sure if the box on the post you saw at P-01 is part of the missile cable system. The buried cable system is pressurized but the pressure comes from compressors at the MAFs and LFs. The box might be for pressurized commercial phone lines coming into the site.

An unexpected location in that it's cut into the side of a hill in an area that apparently has erosion problems. The west side has been covered in rock apparently to arrest the erosion (look for the oval boundary inside the enclosure). The driveway also has lots of "stair steps" to reduce erosion on both sides. Close enough to BNSF railroad tracks that blasting for demolition will require coordination with the railroad.

S-7 is the first Peacekeeper site to be retired starting October 1 2002.

I did stay well away and made no sudden movements :-) S-7 was chosen as the first for retirement because it was due for maintenance. The gate picture shows that the right-hand gate was either installed backward or is a left-hand gate installed on the right (wrong) side; the diagonal brace goes the wrong way and pulls the gate into the ground rather than holding it up off the ground, note the trench it's dug by doing so.

"Masculine Excrescence"
Directly east of a major coal-fired power plant constructed long after the launch facility. I wonder what havoc the site's existence had on the power plant siting and layout, and/or what effect the plant has on the site (e.g. vibration might impact the missile's navigation system, and ground water seepage might increase sump pump rates in the silo). The Terraserver picture is quite nice if you zoom out a bit from the URL I provide above.

On March 3, 2008, Rich Burton sent me a great story about this site: Around early summer of 1978 I believe, work was well under way building that power plant. My flight always worked the north sites P Q R S and T. I was the Flight Security Controller working nights one tour at T-1, the Launch Control Facility. As you can image it was awfully awfully boring during the 7 pm to 7 am shifts, usually nothing ever happens, but the MCN line (the ringer from the missile commander to me topside) begins ringing, we had had severe thunderstorms most all day so my expectation from the commander was a another security alert message from one of the LFs, we often got them during severe weather that I would have to dispatch my Alarm Team to, they had been running these all night and it had just calmed down and they were on their way back to the LCF. In a panicked voice the commander says quick go to the window on the north side of the Security Control Center. Still very anxious he says what do you see, I replied what I usually see just a lot of darkness beyond the boundaries of the LCF. He says nothing? Just about that time there was a flash of lightning on the horizon that was pretty dazzling and I said wow. He sounds like he's crapping himself by now and said what do you see? I said just a flash of lighting. By now I can hear warning buzzers going off over his line with me and he say we've just had a missile away light on the console for T-11, are there any streaks in the sky. I said no and of course we all began our processes to respond and see what was going on. Some time the next day they finally go to the site, seems with all the construction the runoff from the power plant and the heavy rains flooded badly and went to the natural lowest point right beside but outside the T-11 LF and harmlessly into a big gully beyond the site to the west, but it washed out the cables that connect the LCF to the LF. They still had full control over the LF during that time via HF and UHF so there was no true incident. I visited the next day and the erosion was unbelievable to wash out cables that deep and as big around as 6" of hardened cable. To this day, I laugh when I tell that story but I but the poor officer that thought he had lost a missile was downright scared.

U-01, U-02
U-01 and U-02 are on Warren AFB and are used for training. U-01 is for Minuteman III training, U-02 for Peacekeeper. So far these are the only two "sites" where the leading zero is included on the sign on the fence (i.e. you see A-1, not A-01, out in the field). I visited these during an open house 7/22/01. We saw the interior of U-02 including the top of a dummy re-entry vehicle (also the security "A-plug"), but did not go into U-01 due to work in progress. In the Terraserver photo, the two sites are in the lower right with U-02 on the west, U-01 immediately adjacent to the east. Note they are aligned north/south as in the field while the rest of the base in this area is not. Visited again 7/21/02. In U-02 the payload was removed; saw U-01 this time.
