Edwards Air Force Base

Edwards Air Force Base is a USAF airbase located on the border of Kern County and Los Angeles County, California in the Antelope Valley, 7 miles (11 km) due East of Rosamond, USA at {{coor dm|34|57|N|117|52|W|}}. An airbase since 1933, Edwards' has long been a home for flight research and testing and has subsequently been home to many of the aviation's most important and daring research flights.

Geography

The most interesting feature of the 44.5 km² (17.2 mi²) that make up Edwards AFB is the Rogers and Rosamond dry lake beds. These lake beds have served as emergency and scheduled landing sites for many aerospace projects including the Bell X-1, Lockheed U-2, SR-71 Blackbird, and the Space Shuttle. Even today, the lakebeds have black lines painted on it to mark seven official "runways" which are available for pilots operating in the area. Also painted on the playa near Dryden is the world's largest compass rose; inclined to magnetic north (around 13 degrees east of true north) it is used by pilots for calibrating heading indicators. The largest lake bed, Rogers, encompasses 44 square miles (114 km²) of desert. Because of Roger's history in the space program it was declared a National Historic Landmark.

The Rosamond dry lake bed encompasses 21 square miles (54 km²) and is also used for emergency landings and other flight research roles. Both lake beds are some of the lowest points in the Antelope Valley and they can collect large amounts of precipitation. Desert winds whip this seasonal water around on the lakebeds and the process polishes the lakebeds with a new, extremely flat surface; the Rosamond lake bed was measured to have an altitude deviation of 18 inches over a 30,000 ft (50 cm over 9,000 m) length!

Nearby bases

Another element of Edwards' success has been its proximity to other U.S. military bases. Edwards is close to the major city of Los Angeles, but it is also only a short flight south from Naval Air Weapons Station China Lake or Nellis Air Force Base that houses Area 51. Very secret aircraft developed at Edwards or other bases can easily and secretly be flown to a nearby base on a moonless night for maintenance or testing. Air Force Plant 42 and other defense research facilities in Palmdale are located only a few miles south of Edwards. The site of Lockheed Martin's famous Skunk Works, Plant 42, contains Boeing and Northrop Grumman aircraft manufacturing facilities as well. New, top-secret planes are often built at Plant 42 and then flown to the Main Base for night-time testing to maintain secrecy.

Edwards' proximity to other bases has led to the establishment of the jointly-administered R-2508 Special Use Airspace Complex. Containing Edwards, the Navy's China Lake and the Army's Fort Irwin bases, and a significant amount of land in between, R-2508 is completely restricted above FL200 for military use, and in some areas is restricted to the ground. The Department of Defense and its branches use this airspace to train pilots, and to test aircraft and weapons. Joint exercises are often conducted here, and sonic booms can be heard on a regular basis.
