9/11 inside the White House emergency bunker

(Updated: September 11, 2021)

On July 24, the US National Archives released a series of 356 never-before-seen photos, most of them taken on September 11, 2001 inside the emergency bunker under the White House.

The bunker is officially called the Presidential Emergency Operations Center (PEOC), but White House officials also call it the shelter. It was constructed in 1942 underneath the East Wing of the White House, which was primarily built to cover the building of the bunker. It is said the PEOC can withstand the blast overpressure from a nuclear detonation.

One of the very few photos from inside the PEOC available before the recent release

The photos were released in response to a Freedom of Information Act (FOIA) request filed by Colette Neirouz Hanna, coordinating producer for the FRONTLINE documentary film team. They focus on the reaction from then-vice president Dick Cheney and other Bush administration officials during the terrorist attacks.

How Cheney reached the White House emergency bunker was reconstructed in the official report of the 9/11 Commission, which was issued on July 22, 2004:

American 77 began turning south, away from the White House, at 9:34. It continued heading south for roughly a minute, before turning west and beginning to circle back. This news prompted the Secret Service to order the immediate evacuation of the Vice President just before 9:36. Agents propelled him out of his chair and told him he had to get to the bunker.The Vice President entered the underground tunnel leading to the shelter at 9:37.

Once inside, Vice President Cheney and the agents paused in an area of the tunnel that had a secure phone, a bench, and television. The Vice President asked to speak to the President, but it took time for the call to be connected. He learned in the tunnel that the Pentagon had been hit, and he saw television coverage of smoke coming from the building.

The Secret Service logged Mrs. Cheney’s arrival at the White House at 9:52, and she joined her husband in the tunnel. According to contemporaneous notes, at 9:55 the Vice President was still on the phone with the President advising that three planes were missing and one had hit the Pentagon.We believe this is the same call in which the Vice President urged the President not to return to Washington. After the call ended, Mrs. Cheney and the Vice President moved from the tunnel to the shelter conference room.

The Vice President remembered placing a call to the President just after entering the shelter conference room. There is conflicting evidence about when the Vice President arrived in the shelter conference room. We have concluded, from the available evidence, that the Vice President arrived in the room shortly before 10:00, perhaps at 9:58. The Vice President recalled being told, just after his arrival, that the Air Force was trying to establish a combat air patrol over Washington.


The conference room

The newly released photos provide an almost 360-degree view of the conference room in the Presidential Emergency Operations Center. It appears to have two installations for secure videoconferencing: one at the long side of the room and one at the short side, so it can be used from either the long side or the short side of the table.

In the picture below we see the videoconference set-up at the long side of the room. Within a wooden paneling there are two television screens with the camera in between. Right of the paneling are four digital clocks showing the time for various places around the globe, and there's also a wall map of the United States:

In the chair in the lower right corner of the photo above there's a black leather briefcase which looks very much like the so-called nuclear football, the package that contains all the materials needed to authorize a nuclear attack. This "football" not only closely follows the president, but also the vice-president of the United States, and came at risk when vice-president Mike Pence was hastily evacuated from the US Senate on January 6, 2021.

On the screen on the far left we see a videoconference taking place with four participants, including the CIA and the Department of Defense. Reports about the events on 9/11 say there was a secure videoconference in which the White House, the CIA, the State Department, the Department of Justice and the Department of Defense participated.

The next picture shows the videoconferencing monitors at the short side of the room, which can also be used for normal television: other photos show feeds from CNN and Fox. In the corner on the right there's a wooden door with a (mirror?) window. Next to the door on the long side wall, there's a large mirror:

The wall at the long side of the room opposite to the videoconferencing installation has the presidential seal, which appears behind the person leading a videoconference from the chair in which vice president Cheney was sitting, in order to show that this is the White House:

Looking to the right provides a view of the other corner, where we see two doors: first there's a heavy metal door opening to a room with pinkish light. Next to it, at the short side of the room, there's another door which opens to what looks like a corridor with blueish light. Some people seem to come in through that door, so maybe that corridor leads to the entrance of the bunker:

At 6:54 PM in the evening, president Bush arrived back at the White House and joined vice-president Cheney in the Presidential Emergency Operations Center. This was captured in another series of photos. In the picture below we see Cheney and Bush, with on the right side a good view of the vault-like door, which has three heavy-duty hinges and a long downward pointing door handle:

Exactly the same type of white metal door with the long door handle, can be seen in a picture from 1962 of an office next to the Situation Room in the basement of the West Wing (maybe a door to the tunnel leading to the bunker? The current entrance to the PEOC is still a well-kept secret).

Viewing from a different angle, we see more of the wall at the other short side of the room, which was probably never seen before. At the left it has the door to the corridor, and in the middle there are wooden folding doors with handles and a lock. As there are already two banks of monitors for videoconferencing, these doors probably hide something else:

At 9:00 PM president Bush gathered his National Security Council for a meeting in the underground shelter, as can be seen in the picture below. This makes a 360-degree view of the conference room almost complete:

A close look at this photo shows that something is mirrored in the glass pane for the camera of the videoconferencing system in the short side wall of the room. It clearly looks like a world map, more specifically like an automatic daylight map, which must be at the opposite wall, right of the wooden folding doors:


The telephone equipment

The newly released photos show the people in the PEOC conference room regularly making phone calls, using telephones that are somewhat hidden in drawers underneath the conference table. Probably just like the table itself, the drawers are custom made for a device that can be recognized as a small version of the Integrated Services Telephone (IST):

The IST was designed by Electrospace Systems Inc. and manufactured by Raytheon as a dedicated device for the Defense Red Switch Network (DRSN) and hence was called a "red phone". The DRSN is the main secure telephone network for military command and control communications and connects all mayor US command centers and many other military facilities.

The standard version of the IST has 40 programmable buttons for access to both secure and non-secure lines (therefore sometimes called IST-40). Encryption isn't done by the phone itself, but by a network encryptor, after the switch separated secure and non-secure traffic. Although the IST phone had very futuristic looks, it was gradually replaced by the IST-2 since 2003.

The phone we see in the drawers of the PEOC conference room table are about half the size of the standard IST: instead of the 40 direct line buttons, there are just 6, replacing some of the special function buttons above the AUTOVON keypad with the four red keys for the Multilevel Precedence and Preemption (MLPP) function.

This small version of the IST is rarely seen, but it was in the collection of the JKL Museum of Telephony in Mountain Ranch, California, which was unfortunately completely destroyed by a wildfire on September 10, 2015.

The ultimate test for these kind of communications systems is a real emergency situation. However, during 9/11, it came out that the Defense Red Switch Network (DRSN) didn't work like it should have. The 9/11 Commission report said:
"On the morning of 9/11, the President and Vice President stayed in contact not by an open line of communication but through a series of calls. The President told us he was frustrated with the poor communications that morning. He could not reach key officials, including Secretary Rumsfeld, for a period of time. The line to the White House shelter conference room and the Vice President kept cutting off."

Besides the ISTs under the table, there's also a black telephone set, which sits on a shelf or a drawer underneath the wall map of the US. This phone is a common Lucent 8410, used in numerous offices all over the world. Here, it is part of the internal telephone network which is used for all non-secure calls both within the White House as well as with the outside world.

On the corner of the conference table, there's also another kind of communications device: a black box, of which the upper part can be opened up like a laptop. The bottom part however is higher than normal notebooks, even for those days. It's also connected to a big adapter. Maybe it's a rugged and/or secure laptop for military purposes - readers who might recognize the device can post a reaction down below this article.

notebook-type of thing and the small version of the IST.

After 9/11, the government requested secret funding to replace the Roosevelt-era White House bunker with a new facility with upgraded technology but dug deeper and located more securely.* New communications systems and enhancements to environment systems were installed largely at the direction of vice-president Cheney, who had dealt with continuity of government planning over the vast majority of his career.

In 2010, there was a massive underground construction project under the North Lawn adjacent to the West Wing of the White House. With a projected cost of $376 million, large fences blocking the public's view and no discernible changes once the construction was finished, it led to speculations about a new bunker complex.

It was said to be an expanded replacement of the PEOC, with the latest communications and computer systems and environmental technologies that would allow the president and his staff to operate unimpeded for extended periods of time during a crisis.

A mysterious classification marking

A final photo shows then-Secretary of State Colin Powell sitting at the table in the PEOC conference room, reading a document which has a cover sheet for classified information:

The cover sheet seems of light yellowish paper and has a broad dark red border, which is a common feature for these sheets. Most of the text isn't eligable, but the lines in the upper half read like:
TOP SECRET//[....]



The lines in the bottom half are probably the standard caveats and warnings that can be found on such cover sheets. With Top Secret being the classification level, and Eyes Only a well-known dissemination marking, the most intriguing are the letters CRU.

On Twitter it was suggested that CRU stands for Community Relations Unit, an FBI unit responsible for transmitting information to the White House. However, the website of the FBI says that this unit is actually part of the Office of Public Affairs, and as such is responsible for relationships with local communities and minority groups. Although that unit could stumble upon suspected terrorists, another option seems more likely:

After a 2009 FOIA request by the ACLU, a 2004 memo from the Justice Department's Office of Legal Counsel about the CIA's detention program and interrogation techniques was released. The classification marking of this memo was blacked out, but on one page this was forgotten. It read: TOP SECRET/CRU/GST.

In a job posting this was written like "CRU-GST", which indicates GST is a compartment of the CRU control system. Meanwhile we also know that GST is the abbreviation of GREYSTONE, which is a compartment for information about the extraordinary rendition, interrogation and counter-terrorism programs, which the CIA established after the 9/11 attacks.

Because Powell is reading the CRU-document on September 11, 2001 itself, the CRU parent-program must have been established somewhere before that day. It's still a secret what CRU stands for, but it probably covers information about highly sensitive CIA operations.

So this answers a few questions. I was wondering what secure voice was being used. An alternative would be the AT&T/Lucent Tech mod 1100/1150 STU-III. PCM/TDM is common. We're looking at comms to 45MBps i think. The crypto box would not be at LAN speed; more like T-1/T-3:DS3 so units would be KG94/KG95A/KG194. KIV7 i don't remember when available. The corner box w blue lid is a pc or or terminal ( yes, could be a terminal to a minicomputer. ) It is NOT a GrID or GRiDSET computer ( TEMPEST and Rugged TEMPEST pc).
The GRiDSec had a motorola stu-iii cellphone attached on the side. That machine displayed is unknown to me.

It would be really, really cool if you had some inside pictures of Site R, aka Raven Rock, the Underground Pentagon, which you could publish!!!

The laptop looks like an IBM Thinkpad.

Regarding the long-handled door, that's a pretty common design for RF shielded doors like these:

It takes a fair amount of leverage to close the door while all of the beryllium copper fingers are engaging. The long handle helps considerably with this. These types of doors are often used in rooms that are TEMPEST protected.

Amazing what we can see in these photos. It is interesting to see what sort of technology they have in there to communicate. Thanks for sharing!

Also , a STU-III-R or Secure Voice Device may be used.

Is it possible the laptop that has the large port replicator/whatever attached is the football? There's more than just "the button" (or phone) in the satchel (COG facility listings, EAS information, etc.) but I had though these documents would have been loose-leaf or in binders. There is a attaché case leaning against the wall near the device in one of the photos, similar to what a laptop would be carried in. It doesn't appear to be leather, however, and has a shoulder strap. Near the attaché case on the floor are two binders, the topmost of which has the presidential seal on it. Interesting there is a naval officer in close proximity, leaning against the wall, bearing shoulder boards identifying him as a Lieutenant Commander. He also has a Vice Presidential service badge on his uniform and an aiguillette on his right shoulder, identifying him as Cheny's military aide. Who knows.

Very well spotted, and a very interesting option!

TO: Anon : No, it would be the Football. The football would be with
the President ( then G.W. Bush ) ; within sight of the President, not the VP (Cheney). Also, the seal might be the NSA seal; I don't know.

BTW: I mention STU-III-R (STu-III-Remote) or
STU-III Secure Voice Device, because VP Cheney said that "calls dropped" or "there was too much static on the line". Both units were still analogue devices; which could be shared if configured in an tower of an Equipment Closet. Remember, the STU-III-R was just that--a COMPLETE STU-III which supported both VOICE __and__ DATA.
The Secure Voice Device was only for voice--CELP at 4800bps and LPC10e at 2400bps. In my mind, the joint White House Communications Agency (WHCA) and DISA/Navy Team may have configured at least 2 STU-III-R's ; and may or may not have used a multiplexed KG-94 or KG-95 for encrypted voice. The KG crypto boxes would encrypt digitized voice ( end terminal being those IST-1-C (Compact) units -- before communicating. I am glad to have the time to amend my comments.

Regarding the nuclear football: most articles only speak about such a thing being carried with the US President, but it wouldn't make much sense if there wasn't a similar package for the Vice President, and maybe also for the Secretary of Defense.

Imagine the President would be killed in some way or another, how could the Vice President then be able to take over the supreme military command when he is somewhere else and doesn't have a similar device to communicatie with the Pentagon and the nuclear forces?

Some writers therefore also assume there must be more than one nuclear football, at least one with the Vice President:

Fascinating post! Thanks for the breakdown and all the details.

Can you comment on the units that are embedded into the table?
It looks like a switch or attachments plate for mounting conference microphones?


P/K said...

I am not sure what those units in the table are, but mounting plates for conference microphones seems a good option, although a connection for telephone sets is also very well possible (before the newer ones in the drawers were installed).

techie said...

The gold plates embedded in the table are Crown PZM microphones, possibly the PZM-6LPB model. These are the old style PZM's, which were originally marketed in the early 80's.
Newer designs are fully enclosed, with protective grilles.

There is definitely at least 3 emergency nuclear satchels ("The Football") because in the immediate aftermath of the Reagan assassination attempt in 1981, Alex Haig, Caspar Weinberger, and Richard Allen, had a nuclear football and set of Gold Codes with them in the White House Situation Room and then-Vice President Bush also had a football with him. Reagan's military officer with The Football was left behind at Washington Hilton immediately after the assassination (you can see video and photographic footage of the Army officer immediately before, during and after the attack). This is according to pg. 155 of "Rawhide Down," a book on the Reagan assassination. So it's quite likely that Cheney had a nuclear football and watch officer with him in the bunker on 9/11.
