Area 51 News and Timeline

The following is a collection of our observations over the years and other noteworthy news items. Click in the images for more information. For a much more in-depth look at Area 51 history please see Peter Merlin's excellent DREAMLAND Timeline article.

March 2024: Taxiway "A" between the intersection with the center Taxiway "F" and the Janet Ramp "B" is being repaved. Work started between 02/27/2024 and 03/03/2024. Image:

October 2023: The new hangar at the Area 51 North Ramp appears complete. Construction started around April 2023. From the foundation work we expected open covers like a car port. But this photo taken from Tikaboo Peak shows a hangar with closed side walls. The earlier satellite image shows that the hangar has three bays, each suitable for a fighter jet sized aircraft with a 65-85' wing span. Satellite images show that the roof was finished between November 4 and 9, 2023.
Historically the North Ramp has been used by the Red Hats, a unit evaluating "acquired" Russian aircraft. In the current geopolitical climate it seems likely that the new hangar is related to evaluation of new Russian or possibly Chinese aircraft.

April 2023: Beginning construction for three (likely covered) revetments at the North Ramp. The Groom F-16s that used to be parked here are now parked on a different part of the ramp. Each bay has an inside clearance of about 110'. They could house aircraft with a 65-85' wing span. There is trenching for power lines to the new revetments in the south. Also, the Ground Support Equipment (GSE) area immediately west of the ramp was paved in 2022, likely to make more room on the ramp.

2023: Trenching from Hangar 19 east to buried cables leading to some remote radio sites on the field and east of it. Trenching started after 02/22 and appears mostly covered up in the 04/23 satellite image.

2023: New data center south of the new dining hall. Construction started in 07/2020. Building appears complete on the outside in 11/2020. In 02/2022 satellite image the lot surrounding the building is still being worked on. Appears finished and in use in 04/23 image. Google Earth images show a large bank of A/C units and two massive backup generators on the east side. This building clearly needs a lot of power but judging by the parking spots not a lot of personnel. It is very likely a new secure data center. Quite possibly related to the AI-controlled unmanned components of the NGAD project.

2022: New 2-story dormitories. Construction likely started in 2021. Under construction in 02/22 satellite image. Appears finished in 04/23 image. Three old 2-story dormitory buildings here were demolished between 11/2015 and 07/2016.

December 2021: Construction of the new Area 51 Back Gate check point is complete. The old guard shack at the fence line has been replaced with a new high-security check point a few hundred feet inside the perimeter with multiple automatic gates and new fences. The area is secured with countless cameras and floodlights, which are by far the brightest lights in the valley at night.

November 2021: A new microwave tower was added about a mile inside the perimeter near the Area 51 Back Gate. It is very similar to the one at the Groom Lake Road gate (see below) that was finished in October 2001. It likely includes a microwave intrusion detection system and a high speed data relay for the Back Gate and mobile units in the area.

November 2021: A Russian S-125 "Low Blow" radar site was added to the collection of foreign radar systems near the Area 51 Back Gate, about 1/3 mile inside the perimeter. It is clearly visible from the Back Gate area.

October 2021: More hardware was installed on the new tower near the Groom Lake Road guard shack. The tower appears to be part of a new microwave intrusion detection system. It possibly also serves as a high-speed data relay from Mt. Irish to the guard shack and to mobile security units in the area.

July 2021: The new tower near the Groom Lake Road guard shack is finally being used. What appears to be a microwave panel, pointed in the direction of the Mt. Irish radio relay site, and other hardware is being installed.

November 2020: A large new building just south of the new dining hall appears nearly complete. Our July 2020 panorama shows the lot being prepared for the construction (see below). The building is likely part of the new base administration complex.

November 2020: Both scoot-and-hide hangars east and west of hangars 20-23 appear complete now. Our July 2020 panorama showed the western addition still under construction. The "2009 Hangar" that was being demolished in our July photo is completely gone.

July 2020: The previously vacant lot just south of the new dining hall is being developed for new construction. There is clearly some earth moving going on and the screen that separates that lot from the Janet ramp has been extended further south.

July 2020: The massive new scoot-and-hide hangar under construction just east of hangars 20-23 is nearly finished. A second, similar, hangar is now in the early stages of construction west of hangars 20-23. In addition the large "2009 Hangar" constructed at the south ramp in 2009 and damaged a few years ago, is being demolished.

May 27, 2020: Construction is underway at the Area 51 Back Gate for a new, much larger and more secure check point just inside the existing gate.

May 2020: A new antenna tower is under construction on a hill near the Groom Lake Road guard shack. No antennas are mounted to the tower yet but judging by the cable drums visible on the right new wires are being run down to the guard shack. The camera tower next to the new tower was added in 2005 or 2006.

April 2020: A massive new scoot-and-hide hangar is under construction just east of hangars 20-23. The Hangar covers the entire N-S length of the four hangars and appears to extend beyond that in the north. The estimated dimensions are 500ft (N-S) x 150ft (E-W). When completed it will easily be the largest single structure at Area 51 with a 1.75-acre footprint. Construction started after 11/24/2019.

September 2019: A gate was finally installed where Groom Lake Road enters the restricted area. Previously the boundary was only marked by warning signs and there is at least one documented case where a distracted Las Vegas tour guide accidentally drove into the restricted area. The gate was most likely installed because of the "Storm Area 51" event that luckily ended up being a non-event

Late March/Early April 2019: The road just inside the Area 51 Back Gate was secured against intruders with removable hedgehog-style barriers.

Late March 2019: A new Russian radar site was added near the Area 51 Back Gate.

Jan-Apr 2019: A massive construction project is going on at TTR. For three months, dozens of belly dump trucks deliver material to TTR every day. Satellite images show construction around the south end of taxiway Alpha and taxiway Bravo. But the amount of material suggests other construction as well.

Fall 2018: In the Fall of 2018 new "No Drone Zone" signs were posted at the boundary of the Area 51 airspace, which extends for a couple of miles onto public land around Groom Lake Road. If you plan on flying drones around Area 51 please be sure to read our article explaining current restrictions.

May-Aug 2018: The Las Vegas Janet terminal is undergoing an expansion. The addition in the NE corner of the terminal appears to be a two story building.

2017: More FLIR cameras were installed along the Area 51 perimeter in the area north of White Sides, near the "Bald Mountain Gates".

September 2016: Some changes around the Groom Lake Road Guard Shack: Most notably the old guard shack has been removed. The gate area is now reinforced with concrete barriers and a new large fuel tank was added behind the new building. And it appears the garage behind the guard building has been replaced by a similar, but taller garage.

December 2015: The warning signs at the Groom Lake Road "gate" have been replaced with new signs. All of the old signs are gone. There are identical new signs on either side of the road now (see below). No more "Deadly Force", but instead the new signs make it illegal to fly drones in the area. The line across the road is now clearly marked and the border a few hundred feet on either side of the road is marked with razor wire. A new mobile, remote-controlled camera tower now sits next to the road a short way inside the perimeter.

November 2015: The new hangar reported under construction in August 2014 appears to be complete and possibly in use. A June 2015 image still shows it in the final stages of construction. Image Terraserver.

October 2015: The Air Force seizes the Groom Mine overlooking Area 51 after failed negotiations with the owners. The mine was the last private property with a view of Area 51.

August 2014: A new very large hangar is under construction at the south end of the southern taxi way in 08/2014. Construction started in 06/2014. The footprint on satellite images is about 215x215ft. The height is about 85ft. At this point it is not clear whether this will be a hangar housing a new secret project at Area 51 or a scoot-and-hide shelter or possibly a new covered trim pad. A new ramp connects the hangar with the taxi way on its north and south end.

May 2013: The large building west of the Janet ramp appears to be complete. A February 2013 satellite image still shows some construction in the surrounding parking lot. Due to its proximity to other new administrative buildings it is most likely an administrative building or a new dining hall. Image Terraserver.

February 2013: The four older water tanks on the hillside have been removed between 05/2012 and 02/2013. Only the three new, larger tanks are left.

Late 2012: A network of at least 9 new remote controlled security cameras on concrete pads was installed in a valley east of the Groom Mountain Range and Bald Mountain. This part of the Area 51 boundary faces Hwy 375 and is most likely to be visited by curious tourists. These so-called FLIR cameras are night-vision capable.
Trenching for the camera cables all the way from the GL Rd Guard Shack to the "Bald Mountain Gates" can be seen in a May 2012 Terraserver image. A January 2013 satellite image shows the pads complete and camera towers on at least some of the pads. Image Terraserver. Similar cameras were installed at the Back Gate in 2013 and at the Groom Lake Road gate in 2015.

May 2012: The new engine test hangar aka "Hush House" near the Area 51 North Ramp appears to be complete. A satellite image taken a few days earlier shows the construction being wrapped up. Image Terraserver.

May 2012: A new water tower was constructed between 08/2011 and 05/2012. The old red-and-white water tower was removed between 05/2012 and 02/2013.

May 2012: A new hangar was built on the north side of the North Ramp, north of Hangar 6, between 08/2011 and 05/2012.

May 2012: A new quonset hut was constructed near the gravel pit, just north of the concrete plant between 08/2011 and 05/2012.

August 23, 2011: Our new satellite photo shows beginning construction of a new hangar east of the existing North Ramp. Construction was finished in 05/2012. Recent satellite images and our latest Tikaboo Panorama show that it is an engine test hangar, also known as "hush house". Two similar hangars can be found at Nellis AFB near the helicopter ramp at the north end of the base.

August 23, 2011: Large new building near the Base Headquarters. Our 8/23/2011 satellite image shows construction of a new building with a very large footprint near the new Base Headquarters and the Janet Ramp. It measures approximately 255x184', and appears to be fairly tall. Construction continued until 02/2013. The purpose of the building is not clear. Located just south-east of the new Base Headquarters it could be a new dining hall or administrative offices. But our 2014 Tikaboo panorama shows no visible windows. It could also be storage. There is no connection to the flight line, so it is unlikely that it is an aircraft hangar.

March 2011: Another smaller quonset hut-style building first showed up in a 03/2011 satellite image. It is located south of the dormitories and just south-west of the construction site above. It may be related to that construction.

March 2011: Road inprovements. In December 2009 and August 2010 we reported road improvements at the Groom Lake Road gate and at the Back Gate. A March 2011 satellite photo shows that some of the roads inside the restricted area have also been improved during the same time period, including Groom Lake Road, the Backgate Road, the road to the engine test cells on the far south end of the base and the access road to a fairly new radio site on a hill on the north-west side of Groom Lake.

January 7, 2011: A large new Guard Shack is currently being built at the Rachel Back Gate to Area 51. The outside of the sheet metal building is complete, and contractors are busy finishing the inside. The building is about five times the size of the current guard shack, which was built in October 2000. It is located between the current guard shack and the original pre-2000 guard shack. After the paving of part of the Back Gate road last August (see below), this is the second major upgrade to the Back Gate in six months. Clearly this gate is going to see more traffic.

August 21, 2010: The Area 51 Back Gate Road has just been partially paved. The oil pavement is covered with a thin layer of very fine gravel or sand. The pavement goes for 2.2 miles from the Guard Shack to the intersection with a road leading north and eventually back to Hwy 375. The pavement continues up that road for another 0.8 miles and then ends. There is no indication for plans to extend the pavement past that point.

May 24, 2010: Another large new hangar was added at the South Ramp of Area 51 between 11/05/09 and 05/24/10. Ground preparation for the foundation can be seen in our June 29, 2009 Satellite Image. The hangar is located just west of the old Hangar 20-23 storage building. It is most likely connected to the ramp on the south side, opposite another hangar that was added in early 2005.

December 30, 2009: Between 12/15/09 and 12/30/09 the remaining 9-mile dirt section of Groom Lake Road inside the restricted area between the warning signs and the old cattle fence near the north end of the dry lake bed was paved. Groom Lake Road is now a paved road from Area 51 all the way to the warning signs. The 13.8-mile section outside the restricted area, between the warning signs and Hwy 375, remains a dirt road.

June 2009: Our new satellite image, taken on June 29, 2009, for the first time shows the completed new hangar. Other significant changes include the newly paved north ramp, a new running track, several smaller new buildings and the two new radio sites that we discovered in June of 2008.

November 2008 - June 2009: All six of the older Janet 737-200's have been replaced with newer 737-600's, purchased from Air China. The old Janets are currently in storage at the Pima Boneyard in Tucson, AZ.

June 2008: The new hangar, south-east of the old south ramp, appears to be finished. The mound of dirt, which partially blocks the view from Tikaboo, seems to be a permanent fixture.

June 2008: On June 1st, we discovered a new radio site on a hill north of Area 51. The new site has four towers arranged in a straight line, each with what appears to be a small dome on top. The site is directly in line with the north end of Runway 32(R). The towers are arranged perpendicular to the extended runway. We currently have no further information on the site. A very similar radio site was built just east of the recently extended Hangar 19. The four towers are aligned along the east side of the hangar there.

June 2007: New large hangar near the Area 51 South Ramp. A huge new hangar is under construction near the Area 51 South Ramp area. When finished, it will easily be the largest Hangar at Area 51. A large hangar door opening can be seen on the side facing the flight line. Currently a large mound of dirt blocks the view of most of the hangar from Tikaboo. Construction started between January 17, 2006 and June 10, 2007.

2006/Early 2007: New building south of Hangar 18, built between January 17, 2006 and June 10, 2007. This is an extension of the P.E. Building ("Personal Equipment"), where the pilots keep their flight gear, and "suit up" for their missions. Since the South Base area has been expanded quite a bit, it would make sense to need a larger P.E. building as well. Especially with a major new project moving into the new hangar in the near future.

2006/Early 2007: New building at the Explosives Storage Area, built between January 17, 2006 and June 10, 2007. It appears to have a row of windows and a large dark door at the north end. The purpose is not known.

February 2006: New Beechcraft King Air 1900C with tail number N623RA added to the Janet fleet. It replaces the crashed N27RA. Photo by Joshua Nyhus, with friendly permission.

Winter 2005/2006: A new tall structure was built near the radar range at the north end of the base between Sept. 28, 2005 and January 17, 2006. It appears to be a permanent structure, about 180 ft. tall, located at approximately N 37° 14.790' and W 115° 49.392'. The exact function of the structure is not yet known. It may hold a new radar array for RCS tests or other radar measurements.

2005: New Base Headquarters Building. This new building, just south of the TESC building, appears to be the new Base Headquarters. It is roughly twice the size of the old Base Headquarters. More office space for the administration of an expanding base...

Spring 2005: Hangar 19 extended north and south to triple its original size. A substantial extension was added to the Arm-/De-Arm Hangar 19 in early 2005. In summer of 2005 the hangar has grown to three times its original size. The new additions appear to be open at the bottom. The reason for this addition is unknown.

Spring 2005: New hangar built just east of Hangar 9. A tall new hangar was constructed in early 2005, just east of Hangar 9. The height of the hangar, in combination with indications that there is a new UAV project under development at Area 51, could mean that it is used to mount a drone on top of a carrier aircraft. In summer 2005 the new hangar was completed, but there is still construction activity in the vicinity of the south ramp, which has been re-paved in late 2003 or 2004.

March 16, 2004: One of the Beechcraft King Air Janets, tail number N27RA, is destroyed in a crash en-route from Area 51 to TTR, killing the pilot and all four passengers.

10/2003: Increased construction traffic through North Gate. Sources in Rachel report a significant increase of heavy construction equipment traffic through the North Gate into Area 51. This may be connected to the construction in the south ramp area (see below).

07/2003: South Ramp is being re-paved. Satellite images show that the south ramp, just north of hangars 9-16, is being re-paved. It seems likely that these hangars, which had not been used for a while, will be used for a new project.

Spring 2003: New Taxiway constructed at Area 51. Construction for a new center taxiway started in early 2003. By summer of 2003 it was nearly completed. Click here for a Satellite Image.

Late 2002/early 2003: Two new hangars constructed near the workshops in the west part of the base. Two fairly tall identical hangars were added side by side between the workshops in the west part of the base and the shipping and receiving facility. They are connected to a complex of buildings whose purpose is not known. It appears that the building complex is at least partially fenced in. The fence runs between the two hangars, so that one hangar is inside and one outside the fence. The hangars were constructed in late 2002 or early 2003.

Late 2002/Early 2003: Two large new Fuel Tanks added at Area 51. The older fuel tanks on the south end of the base have been removed, and two large new tanks have been constructed to replace them. By spring of 2003 the fuel tanks were completed.

12/14/2001: Area 51 Security Guards Strike update. The Cammo Dudes are back to work, but their two-day strike caused the delay of a nuclear test at the Nevada Test Site. Click here.

12/11/2001: Area 51 Security Guards on Strike. The famous Cammo Dudes, the Area 51 security guards, went on strike on Monday 12/10/2001 for better pay. They are picketing at the Las Vegas Janet terminal, where they normally board the Janet planes to Area 51.

Late 2001: New trucks for the cammos (again!). In late 2001 we received the first reports of yet another new type of Cammo vehicle: Dark gray Chevy 2500 4x4 Pickup Trucks. The Ford F-150's, put in service only in 1999, did not last very long. Since 2002 only the Chevy Pickups and some of the older Jeep Cherokee are in use.

9/17/2001: Radio Site on Flat Top gone. On a routine field trip up to Flat Top we found that the Radio Facility there is completely gone. It may have been replaced by the newer system in different location.

9/05/2001: First Live Broadcast from Tikaboo Peak. As a world premiere, the Dreamland Resort successfully made the first ever Live Broadcast from the top of Tikaboo Peak. At 8pm PDT a small group of Dreamland Resort team members went on the air to describe the amazing view of Area 51 to hundreds of listeners worldwide on the Internet.

09/2001: Tank Farm at Area 51 removed. Our latest Area 51 panorama photos from Tikaboo Peak in early September 2001 show that the tank farm at the south end of the base has been removed, except for the southernmost two tanks.

05/2001: New Runway 12/30 designated at Area 51. The southern taxiway was designated "Runway 12/30" between 4/16/2001 and 5/5/2001. The markings can be seen on newer satellite images. The new runway is 5420 ft. long and 150 ft. wide. Since this is a fairly short runway it will likely be used for UAVs.

10/2000: Area 51 North Gate security upgrade. The Area 51 North Gate, also known as the Rachel Back Gate, has been upgraded for higher security. There is now a more secure double gate surrounded by a chain link fence, and the guard shack has been moved back inside the perimeter.

04/2000: Area 51 Janet Ramp is re-paved. Satellite images show that the ramp south of the Janet terminal at Area 51 is being re-paved. During the construction Janets use the ramp west of hangars 20-23.

12/22/1999: Phone outage at Area 51. On 12/22/1999 there was a 5 hour phone outage, affecting the Las Vegas and Pahrump, NV areas. Also affected, and specifically mentioned in the "Initial Service Disruption Report" from Sprint, Area 51 (!)

12/16/1999: Area 51 taken over by the US Air Force. An article published in the Las Vegas Review-Journal on 12/16/1999 states that Area 51 was officially taken over by the Air Force. It had been in use by the Air Force before, but was officially under the control of the Department of Energy. Click here for the full story.

10/30/1999: New trucks for the cammos. Since 10/30/1999 a champagne golden '99 Ford pickup truck with 1999 license plates (99B01203) is often sitting on Cammo Hill. This could be the next generation of Cammo vehicles, to replace the white Jeep Cherokees, which mostly have been in service since about 1995.

08/1999: Changes at EG&G. In August, 1999 EG&G Technical Services, Inc. was acquired for $250 million in cash by The Carlyle Group, a Washington D.C. based private global investment firm with industry focus in aerospace, consumer products, defense electronics, environmental services, health care, information technology, the Internet, real estate and telecommunications.
The remaining groups of EG&G (NYSE:EGG) changed their name to PerkinElmer, Inc. (NYSE:PKI) in October 1999.
EG&G Technical Services contracts for Area 51, providing base security (yes, the famous cammo dudes). It will be worth watching if these changes have any effect on operations at the base, and if there is a connection with the recent takeover by the US Air Force (see below).
Thanks to "Bravo X-ray" for bringing the above facts to our attention.

June/July 1999: Cedar Gate Road being paved. Cedar Gate Road from State Hwy. 375, mile marker NY 43.6 (just north of Queen City Summit), to the Cedar Gate of the Nellis Ranges has been paved in June / July 1999. It used to be a maintained dirt road before. Now it is a smooth two-lane asphalt road with no speed limit, which suggests a planned increase of activity on that road.

We have observed heavy unmarked white trucks entering the Base through the Cedar Gate in October 1999. No information on the cargo is available, except that judging from the large air conditioning unit it needs cooling.

We have observed heavy construction equipment being transported into the base on a white unmarked flatbed truck on the Back Gate Road near Rachel in July 1999.
