- "National security" airstrips in California's desert
- ____________________________________________________
- by Paul McGinnis, February 19, 1995
-
- Aviation Week (February 6, 1995) mentioned the existence of Northrop's
- Tejon Ranch radar cross section range in California. Because I've been
- out in that area several times to see the facility, I have prepared
- some information telling people how to get there with some other useful
- information.
-
- The Tejon Ranch installation is located at the base of the Tehachapi
- Mountains in a northwestern part of the Antelope Valley. Some people
- have referred to this place as the "ant hill", but I think they are
- confusing the Northrop installation with the Ant Hill Oil Field airstrip
- on the other side of the Tehachapi Mountains, east of Bakersfield.
-
- To give you some idea of how far you will have to drive to get there,
- it should be noted that the Northrop facility is approximately 105
- miles from downtown Los Angeles, by road. (1 mile = 1.609 kilometers)
- I recommend using an offroad vehicle (4WD) or pickup truck to get out
- to see the facility, because some of the roads are quite rough. (I've
- navigated the dirt roads in the area in a 1988 Honda Civic, and I
- have to had to worry about damage to the car, because of these dirt
- roads.) The roads near the facility can be quite rocky or washed out
- in places. There are numerous dirt roads crisscrossing the area, that
- are usually not marked, and some are poorly maintained. It would be
- quite easy to get lost or have your car break down up there. When the
- maps show unimproved dirt roads in the area, they are not joking.
-
- Using the FCC database, I have found that the facility is located at
- 34 degrees 55' 25" North latitude, 118 degrees 31' 48" West longitude.
- The airstrip is not shown on the 7.5 minute U.S. Geological Survey
- topographic map of the area, dated 1973 (Liebre Twins Quadrangle,
- 34118-H5-TF-024). It also does not appear on the 1986 Defense Mapping
- Agency aeronautical chart JOG NI 11-4. However, it appears in DeLorme
- Mapping Company's 1990 "Southern & Central California Atlas & Gazetteer"
- collection of topographic maps.
-
- In this part of the desert, the dirt roads are given numbers. Although
- the FCC records list the Northrop facility at 7000 230th Street West,
- you can not get there by going down Avenue D, and going north on
- 230th Street West. Because it is behind some low hills, the facility can
- be difficult to see. I will provide directions to two locations -- one
- location is just outside the Northrop gate (poor viewing of the base,
- but an interesting excursion) and the other location allows you to
- see the facility from perhaps 3 miles to the east. The eastern viewing
- location also gives you quite a panoramic view of the Antelope Valley,
- and surrounding mountains. You should zero your trip counter on your
- vehicles odometer as you exit Highway 14.
-
- To get near the area, take Highway 14 north from Palmdale or south from
- Mojave. Exit at Rosamond Blvd. (look for the sign that reads "Edwards AFB
- / Rosamond". (Edwards AFB is quite a ways to the east.) Go west on
- Rosamond Blvd. At 2.3 miles west of Highway 14, you will see one of my
- dining recommendations in the area, Villa Basque restaurant. Keep going
- west -- at 15.4 miles from Hwy. 14, the paved road will make a sharp
- bend to the left and become 170th Street West. Go right (north) on the
- dirt road instead. At 16.9 miles from Hwy. 14 (1.5 miles north of Rosamond
- Blvd.), you will see a sign that says Broken Arrow Road (with an arrow
- pointing along a road that runs towards the northwest.) Broken Arrow
- Road leads directly to the Northrop gate several miles away (sorry, I
- didn't take mileage readings for that road.) If you continue north on
- 170th Street West, you will end up at the eastern viewing site. At the
- base of the Broken Arrow Road sign, someone painted a blue object (a
- skull??) on a rock.
-
- If you continue north, you will encounter a short stretch of very rough
- road (a "washboard road" if you will...). As your trip counter goes
- past 18.1 miles (2.7 miles from Rosamond Blvd.) you will pass an antenna
- on a pole. I'm not sure if this is for a road sensor, like on the
- Groom Lake road. At 19 miles (3.6 miles from Rosamond Blvd.) the road
- will go west for 0.5 miles and then go north again. The viewing site is
- 20.6 miles from Hwy. 14 (5.2 miles from Rosamond Blvd.) Look towards
- the west (left) and there it is!!
-
- You will see a hangar, radar antennas, a water tank, and several smaller
- buildings on top of a small hill. It looks like the facility probably got
- more use during the B-2 Stealth bomber's early testing, a few years ago,
- than it does these days. (The canyon behind the facility is Tylerhorse
- Canyon.) My estimate for the runway length is 4000 feet (1231 meters).
-
- If you follow Broken Arrow Road, it will eventually come to a gate, like
- those used by cattle ranchers, marked with "Private Property" signs. You
- should not go beyond the gate, to prevent getting charged with trespassing.
- (I have seen local law enforcement in the area.)
-
- Apparently, to keep Northrop employees on the road, and prevent them
- from getting lost, someone came up with the idea of using signs with
- red arrows on them to point the way, and keep the workers on the right
- road, so you can follow the red arrows also. There is at least one
- creek along Broken Arrow Road that may have water in it -- cross carefully
- so you don't get stuck in mud.
-
- It is very unlikely that you will see anything classified up there. Just
- enjoy the expedition, watch the desert hares and flocks of birds, and
- relax outdoors, and you won't be disappointed. For those with scanners,
- here are some Northrop frequencies: (I haven't heard much activity, but
- I've been up there on weekends.)
-
- 462.35 MHz -- main channel for the facility (repeats 467.35 MHz)
-
- 123.35, 123.525, 314.6, 382.6 MHz -- Northrop aviation channels (used
- at Air Force Plant 42 in Palmdale, Mojave airport Northrop operation,
- and Edwards AFB Northrop operations also.)
-
- 158.28 MHz -- general use Northrop channel (also used at Edwards AFB).
-
- Another interesting place is the CIA's El Mirage Flight Test Facility,
- used for testing their Gnat-750 and Predator UAVs (Unmanned Aerial
- Vehicles, i.e., reconnaissance drones.) These UAVs resemble large model
- airplanes. The El Mirage facility is operated by the manufacturer of
- the UAVs, General Atomics Corp. It has a 3700 foot (1138 meters) long
- runway in DMA aeronautical chart JOG NI 11-5. To get there, exit
- Highway 14 at Avenue P in Palmdale, and go east. You will go past
- Air Force Plant 42 (Lockheed's Skunk Works occupies the big hangar
- at the western part of Plant 42) and the Blackbird (SR-71) Museum.
-
- (Most of this trip is on paved roads). Go north on 40th Street East,
- and then east on Avenue N. Go south on 90th Street East and make a left
- turn (east) on Avenue O. You will pass Alpine Butte Wildlife Sanctuary --
- the buttes there are not too difficult to climb, and give a fine view
- of Edwards AFB to the north, Plant 42 to the west, and El Mirage and
- Lockheed's Helendale radar cross section to the range. It would be a
- good spot to camp on and watch the aerial activity above the Antelope
- Valley. Continue east on Avenue O until you get to 240th Street East
- and go south (right) on 240th Street East. Go south to Avenue P, and
- then east (left) on Avenue P. You will go through the town of El Mirage.
- Look for a sign that reads El Mirage Airport Road and make a left turn
- there (go north on that road.)
-
- At the end of the road, there will be an aircraft graveyard to the left
- (west) and the El Mirage facility to the north. Offroad vehicle and
- motorcycle enthusiasts use the bed El Mirage Dry Lake to the northeast.
- (Sorry, I don't have any radio frequencies for the El Mirage facility.)
-
- You could also continue on to Lockheed's radar cross section range north
- of Helendale, California. For more details on the Lockheed facility, you
- can use Internet FTP and connect to host ftp.shell.portal.com . My Lockheed
- report is file lockheed-rcs-report in the directory /pub/trader/secrecy.
- In that report, I mentioned photos of a radar cross section (RCS) testing
- pylon. I may have overestimated the height of the pylon, if the pictures
- I saw are of scale models for RCS, instead of actual aircraft. This is
- the facility that Ben Rich mentions in his book, where they put a scale
- model of the Stealth fighter on a pole, and there was no radar return
- until a crow landed on the model.
