The Black Hawk Security Helicopters


A fleet of three Black Hawk helicopters, stationed at the north end of the base, provide air security around Area 51. More accurately they are Sikorsky HH-60U "Ghost Hawk", a new and upgraded version of the Black Hawk. Only four HH-60U exist. Three are based at Area 51 and one is based at Joint Base Langley-Eustis, VA. They were converted in 2011 from the U.S. Army HH-60M, originally developed to guard U.S. nuclear missile sites.

The Langley-based Ghost Hawk is said to be used as a test bed for stealth helicopter R&D. The three Ghost Hawks at Area 51 replaced the older generation MH-60G Pave Hawk between 8/2011 and 2/2013, likely in late 2011 or early 2012. Scroll down for some photos and info on the older Pave Hawks. The MH-60G had a retractable in-flight refueling probe that was often mistaken for a large gun by visitors to the area. The new HH-60U do not have a refueling probe.

Several times daily one of the Black Hawks can be seen doing its rounds out of the base and across Tikaboo Valley, patrolling the Area 51 perimeter. Visitors in the early 1990's report the Black Hawk would sometimes "sandblast" curious tourists. We are not aware of any such instances in recent years. However, the chopper may come out to investigate if curious visitors explore sensitive areas where it is difficult for security on the ground to keep track of them.

One such area is Roadblock Canyon, where access to the old trail up to Freedom Ridge has been blocked by a man-made rockslide blocking the road in a canyon. Of course access to Freedom Ridge is no longer possible after the 1995 land withdrawal, but for several reasons it is still a rather interesting (and sensitive) area. It is very easy there to disappear from view of the watchful eye of the Cammos.

In radio comms with the base the security chopper mostly uses the callsign SABRE31.

In recent years the three Area 51 security choppers have each made several round trips to Waco, TX. They usually take two days for each leg with an overnight stop along the way. The dates listed below are the day they left Area 51 and the day they returned there.

The most likely destination in Waco is L3Harris, a major contractor for communications equipment in the NTTR. They have a large facility with over 1,300 employees in Waco and provide, among other services, military aircraft modification. Very likely they are modifying the communications gear onboard the Groom choppers with new, secure equipment.

The fourth HH-60U, 10-20324 assigned to an experimental unit at Felker AAF, VA, has not made any trips to Waco in that time frame. So it is likely that the modifications are specific to equipment in use at Area 51.

Ogden ALC is part of Hill AFB, UT, which seems to have some kind of connection to Area 51. Ogden uses the tail code "HAFB" for fixed-wing planes. Please let us know if you see any planes with that tail code in the Groom Area. Note the four letter code, as opposed to the usual two letter tail codes (like HI and HL for other units of Hill AFB).
