The deserts have always held a certain primal appeal for many people. But there is one American desert that holds a special high-tech fascination for many aviation and radio buffs. Maybe it is the strange lights that appear to dance in the night skies over the desert floor or rumors of captured flying saucers. Maybe it is the strange looking aircraft that cannot be seen on radar, or the rumbling from aircraft engines that cause earthquake sensors to trigger false seismic alarms. Or, maybe it is just the Cold War secrecy that draws our attention to this place.
But the Cold War is over - at least this is what the American public has been told by our government and the media. And (if you believe a recent story in Popular Mechanics), we could be seeing the end of an air force base that is so secret, it doesn't exist. It is perhaps the most secret military installation in American history.
This base is nestled between steep mountains in the Nevada high desert. It is located inside the recesses of the off-limits Department of Energy (DOE) Nevada Test Site, 90 miles due north of Las Vegas. This phantom air force base consists of an airfield (among the largest in the United States), dozens of aircraft hangars, miscellaneous support buildings, several satellite dish gardens, a control tower, and a handful of U.S. Air Force 737 aircraft that fly in and out of its airspace daily.
Because its mission is so secret, its existence is not reflected in any federal government budget allocations. It doesn't appear on any U.S. Geological Survey maps. Check a Las Vegas sectional aeronautical chart and you won't find this airfield on it. In fact, the base doesn't even have an official name.
But the base that doesn't officially exist is there, and radio hobbyists know this phantom in the Nevada desert as Groom Lake or Area 51 of Independence Day fame.
A Step Back in History
In April 1955, Lockheed test pilot, Tony LeVier, was sent by his boss, Kelly Johnson, head of the Lockheed "Skunk Works" (the unofficial name for Lockheed's special projects division), to search for a remote site to test the new U-2 reconnaissance spy plane. He found a deserted spot in the central Nevada desert right next door to the Nevada Nuclear Test Site.
"I gave it a ten plus. Just dandy. A dry lake bed about three and a half miles around. I had some sixteen-pound cast-iron shotput balls with me and dropped them out to see if the surface was deep sand. Damned if it wasn't as hard as a tabletop," said LeVier.
Several days later, LeVier flew Johnson, and CIA special assistant Richard Bissell, to the site. Bissell remarked, "This will do nicely." He even liked LeVier's proposed name for the site, "Paradise Ranch."
Johnson decided to place a runway at the south end of the dry lakebed known to the locals as Groom Lake. Work then began on this covert facility under the direction of Kelly and the Lockheed Skunk Works.
Fronting for the CIA under a phony C&J Engineering logo, Kelly hired a construction company to put in water wells, two hangars, an airstrip, and a mess hall in the middle of the desert in blistering 130-degree summer heat.
In his book, Skunk Works, Rich Ben writes:
"At one point, the guy Kelly used as his contractor put out a subcontracting bid. One subcontractor warned him: 'Look out for this C&J outfit. We looked them up in Dun & Bradstreet, and they don't even have a credit rating.' This base was built for only $800,000. 'I'll bet this is one of the best deals the government will ever get,' Kelly remarked to several of us. And he was right."
On August 4, 1955, the first flight of a U-2 spy reconnaissance plane was made at Groom Lake. Of course, the rest is history. But the U-2 wasn't the last secret aircraft to spread its wings on the dry lake bed of Area 51. In the 42 years since that first flight Groom Lake has been the home of many top secret aircraft first and it is still in use today.
The Big Picture
Groom Lake is part of one the hottest areas in the world for the military aircraft monitor. It is part of the sprawling three million acre Nellis Air Force Range.
Located in North Las Vegas, Nevada, the primary mission of Nellis Air Force Base is the training of military aircrews in realistic air combat exercises. The vast, Connecticut-size Nellis Range Complex, north and west of Las Vegas, is attached to the base. These ranges contain at least two secret bases, the aforementioned Area 51 and the Tonopah Test Range, both used for testing of advanced technologies. The DOE Nevada Test Site (frequencies in Table 1 and 2) - home to the U.S. government's nuclear weapons testing - is also a large part of the Nellis Range Complex.
For the military monitor, this is Mecca. Nowhere else in the world will one find a larger collection of military aircraft, military activity, and military radio frequencies. In most places around the country, monitors claim that the 225-400 MHz is like a wasteland on their scanners, but not on the Nellis ranges. Hundreds of frequencies have been cataloged and many more await discovery. A large sampling of those frequencies can found in our exclusive list in Table 3.
What follows are the descriptions of a few of the more interesting facilities on the Nellis Range.
Tonopah Test Range
The Tonopah Test Range (TTR) is a 625 square mile area located at the very north end of the Nellis Complex, about 32 miles southeast of Tonopah, Nevada. First opened in 1957, it has been a major test facility for DOE funded weapons programs by Sandia Laboratories of New Mexico. This facility is heavily instrumented with camera and radar tracking devices that record data from non-explosive aspects of nuclear weapons testing such as artillery shell testing, bomb drops, cruise missiles, rocket tests, and parachute testing.
In 1984, TTR also became host to the first F-117 stealth fighter squadron, prior to its being moved to Holloman AFB in New Mexico.
There are three electronic combat ranges located on this north range that provide user-selectable, low-to-high electronic threat environments. These ranges are:
Tonopah Electronic Combat Range (TECR) - The TECR is the main, manned threat simulator range. It has generated mock electronic threats that include surface-to-air (SAM) missile sites with numerous anti-aircraft artillery (AAA) fire control radars to simulate a realistic array of enemy signals.
The following military air ("milair") frequencies have been reported from this range: 253.2, 253.6, 280.0, 284.0, 343.2 MHz.
Tolicha Peak Electronic Combat Range (TPECR) - The TPECR contains long- and short-range strategic threat and associated point defense systems, along with acquisition and ground control intercept (GCI) radars. The TPECR simulates enemy defense deep interdiction and offense counter air targets. TPECR is a smaller range than the TECR and is less capable. It is located on Pahute Mesa about three miles northeast of Tolicha Peak.
The following milair frequencies have been reported from this range: 235.2, 280.0, and 284.0 MHz.
EC South - This is a limited EC range that contains a few electronic threat simulators representing both missiles and AAA systems. The EC South range is not tied into the integrated air defense systems of the TECR/TPECR.
Nellis Area II (Lake Mead Base)
Nellis Air Force Base Area II (once known as the Lake Mead base), is a separate facility about a mile northeast of the main Nellis base. Area II is a munitions storage facility for both conventional and non-conventional munitions (reportedly 200 nuclear weapons and air launched cruise missiles).
Area II is dominated by a high-security triple-fence compound encompassing several dozen earthen bunkers. This fence is well-lit at night and can easily by seen from Interstate 15 and passenger jets on approach to McCarran International Airport at Las Vegas.
In additional to the munitions storage, Area II contains the Nellis Federal Prison Camp, a minimum security prison occupying old air force dorms. The following frequencies are being used at this federal prison: 170.650, 170.875, 170.925, and 409.250 MHz callsign KVL 331.
It is also the home for the 820th Red Horse Engineering squadron depot. Look for their communications on 149.175 and 149.500 MHz. HF equipped listeners might want to watch 11589.0 kHz (USB) for Red Horse activity.
Department of Energy
DOE is a large government player in the Las Vegas area. Over the years, several DOE civilian contractors have been associated with Area 51. One of the largest players, EG&G, was the prime contractor for the DOE/Nevada Test Site. EG&G also has played a large role in Area 51 operations.
Additional companies associated with NTS operations included Radio Systems of Nevada (RSN) and Reynolds Electric Company (RECCO). According to an anonymous source these companies no longer have their contracts (except a special segment of EG&G). Those operations have now been taken over by Bechtel of Nevada. It is reported that EG&G is still involved in "special projects" (Area 51 almost by definition).
The status of the radio systems that EG&G used to support their operations on the NTS is unclear at this writing. We hope to have a clearer picture in the months ahead.
The most visible presence of the EG&G company continues to be at the McCarran International Airport. EG&G provides support at the Escondido facility for the daily Janet flights that ferry personnel to Area 51. Prior to the Air Force taking control of the Boeing 737s that fly north to Groom Lake, a civilian company, Key Airlines, had the duty to transport groom Lake personnel. Look for Escondido facility radio activity on 164.250 (Security) and 164.750 (Maintenance support). Air to ground communications can be heard on 118.7 MHz (callsign Gold Coast)
Janet flights fly north from McCarran to Groom Lake and enter R-4808N (Groom Lake airspace); they contact Dreamland Control (Area 51 approach control) on civilian VHF aeronautical frequencies. Over the years, these frequencies have changed (sometimes yearly). When the aircraft come within five miles of Groom Lake, control is handed off to the Groom Lake tower (again on a VHF civilian frequency).
Janet flights also fly up to the Tonopah range and it is reported that some flights originate from Edwards AFB (home of AFFTC-Air Force Flight Test Center).
The Air Force Flight Test Center (AFFTC) is headquartered at Edwards AFB, California. There is ample evidence to indicate that AFFTC operates the secret base at Groom Lake. This assumption is drawn because AFFTC appears on many documents regarding base security and land use. AFFTC is also the logical master, because Area 51 was founded for the testing of secret aircraft and Edwards is responsible for that function. AFFTC, Det 3, is the organization responsible for Groom Lake.
In addition to AFFTC military personnel, Groom Lake is home to numerous civilian aerospace personnel that are there to support the testing program. An eyewitness of Groom Lake operations has revealed who occupies the various sections or sites on the base. Here is that exclusive list:
|Northrup/Grumman||B-2 bomber, Tacit Blue, A-12 follow-on|
|Unknown||No air vehicles spotted|
|Lockheed||A-11, U-2, SR-71, F-117 (Have Blue), Darkstar (Tier 3- UAV)|
|Unknown||Several variants of C-135 aircraft sitting around|
|-----------||Seems to be in a caretaker status|
|Teledyne Ryan Aero||Tier 2+ and Tier 3+ UAVs|
Since these are civilian companies, scanner enthusiasts might want to check VHF/UHF itinerant frequencies for activity from the base. Be sure the following frequencies are loaded into your scanner: 151.505, 151.625, 154.570, 154.600, 158.400, 451.800, 456.800, 464.500, 464.550, 469.500, 469.550 MHz. You should also have the U.S government itinerants (27.575, 27.585, 163.100, 168.350, 408.400, 418.050, 418.075, 418.575) and aircraft emergency (121.500/243.0) frequencies loaded.
And Then There are the Rumors
One rumor about Groom Lake that many citizens take seriously is that area S-4 is where the remains of the Roswell flying saucer was taken and where the US government is reverse engineering a flying saucer. This is all supposed to be in an area located south of the base at a secret mountain facility near Papoose Lake.
There has never been any creditable evidence to support this conclusion and, based on the information above, the author seriously doubts any of these claims. This is a Deep Black base that supports advanced technology aircraft, but that is all.
Taking a trip to Dreamland?
Area 51 is a closed government facility; anyone wanting to take a trip to Groom Lake should be aware that you will not be allowed on or near this closed facility. There are signs posted indicating that deadly force is authorized (they mean serious business). The security force you will run into are known as the "cammo dudes" (so named by Glenn Campbell at the Area 51 Research Center). This security force is part of the AFFTC, DET 3 SP unit, and they don't mess around. You will find them on 141.550 and 142.500 MHz.
According to a copyrighted story in the June 1997 issue of Popular Mechanics magazine, the cammo dudes are gone and with it the beginning of the end of Area 51. According to the story written by Jim Wilson, Science/Technology editor, Area 51 is shutting down and moving to the Dugway Proving Grounds in Utah. However, as of this writing, Janet flights continue into Groom Lake and we do not see any let-up in activity. The PM story is highly suspect in its content and conclusions.
If you are planning a trip to the Groom Lake vicinity, I highly recommend you purchase a copy of Glenn Campbell's Area 51 Viewers Guide. This is the best and most informative work on the Groom Lake/Nellis Area and a requirement for those wanting to make the pilgrimage. You can find more information about the Viewer's Guide and Groom Lake on the internet by visiting Campbell's Internet site (the best on the web) at: http://www.ufomind.com or write Glenn Campbell, P.O. Box 448, Rachel, Nevada 89001.
An article of this magnitude could not have been written without the help of numerous individuals and hundreds of hours of monitoring and research. I would like to specifically thank four individuals who really helped behind the scenes: Captain Xenon, my friend in the south, Glenn Campbell, and Bruce Ames. I dedicate this article to the person who got me started on this project several years ago: a good friend, Ed Flynn.
There are many rumors, speculations, and wild theories about Groom Lake that have circulated over the years (we can now add the base closing to the list of oddities). But there is one rumor you can put to rest for certain: Groom Lake does exist and it isn't just a "Phantom in the Desert."
