AREA 51
Area 51, also known as Groom Lake, Watertown Strip, Dreamland, or The Ranch, is one of the US government's most highly classified test facilities. The activities which take place at Area 51 are some of the military's most sensitive test programs, and have included the flight testing of the U-2, the A-12, and the HAVE BLUE stealth technology demonstrator.
The following image provides an overview of the expansive Area 51 complex:

Area 51 is home to some unique structures, both historical and current. The original AQUATONE and OXCART hangars can still be seen, with the OXCART hangars likely having served as the home to the RED HAT aircraft. The 24,000 foot runway, the longest in the world, is still present as well, but this is believed to no logner be operational, as denoted by the X markings on the northern end and the fact that the new runway uses the same numbers.
The following annotated image depicts some of the most interesting and significant facilities located at Area 51:

Various test facilities are located at Area 51. The location where the A-12 was pole-mounted for RCS testing can still be seen adjacent to the lakebed's western edge. The DYCOMS radar sensor system can also be seen. DYCOMS is an airborne RCS test system used to evaluate the radar signatures of aircraft which overfly the facility.
The following annotated image depicts Area 51's DYCOMS RCS test facility:

A facility which has been referred to as the QUICK KILL radar site is also present adjacent to the DYCOMS facility. The terminology may indicate that this is an electromagnetic weapon of some sort, designed to disable electronic systems.
Area 51 is not the only significant test site in the Nevada Desert. Some of them, by nature, may even be more secretive.
TONOPAH ELECTRONIC COMBAT RANGE
Located near Tonopah Test Range, the former home of the then-classified SENIOR TREND fleet, is an expansive complex housing what may be some of the most secretive items in the United States. A vast electronic combat range containing numerous radar systems is home to more than a few examples of Soviet and Russian radar systems. While their presence may be an open secret, as it has been stated in the past that the OXCART was tested against Soviet radar systems, the means of their acquisition is understandably highly classified. One can speculate that some systems may have been sourced from cash-strapped former Soviet republics, in the same manner that Moldova's MiG-29 fleet was acquired.
The following annotated image provides an overview of the most prominent features of the Tonopah Electronic Combat Range:

Not all of the radar systems present at the Tonopah site can be identified, due to the resolution of the imagery, and some of them may not even be radar systems at all. However, some of the radars are readily identifiable due to their large size. Situated around what appears to be the primary facility are four raised berms, each appearing to house a radar system. The northern and eastern berms are home to Soviet-era P-35 (BAR LOCK) E/F band EW radars. Just south of the main facility is another pad which appears to house an RSN-125 (LOW BLOW) engagement radar associated with the S-125 (SA-3 GOA) SAM system.

TOLICHA PEAK ELECTRONIC COMBAT RANGE
The radar range near Tonopah is not the only electronic combat facility in the Nevada desert. At 37°18'58.48"N 116°46'50.93"W the Tolicha Peak Electronic Combat Range can be found.
The following annotated image provides an overview of the most prominent features of the Tolicha Peak Electronic Combat Range:

The mainstream belief is that the Tolicha Peak facility houses numerous radar systems to support RED FLAG operations, given its proximity to two mock airfields. A more detailed examination provides an alternative, that of foreign SAM system exploitation and testing. Elements of S-125 (SA-3 GOA), S-200 (SA-5 GAMMON), and S-300PS/PM (SA-10B GRUMBLE) SAM systems can be found on the grounds of Tolicha Peak.
The following annotated image depicts what is likely an S-125 facility at Tolicha Peak. The object to the west of the RSN-125 (LOW BLOW) radar system would appear to be some sort of three-round launcher, or an unusual radar system, and does not resemble the 5P71 or 5P73 launchers found at operational S-125 sites around the globe, and as such may be some sort of dedicated test equipment.

The following annotated image depicts an S-200 launch site at Tolicha Peak. There would appear to be a second missile, albeit with the control surfaces removed, nearby. The 5N62 (SQUARE PAIR) engagement radar is not colocated with the launch facility and was not readily identified, but the facility 0.47 kilometers to the southwest is a candidate.

The most interesting facility found at Tolicha Peak is the S-300P launch site. It would appear that a nearly complete collection of radars is present, as well as two TELs and a 40V6 mast assembly. The 40V6 is used to mount either the 30N6 (FLAP LID) engagement radar or the 76N6 (CLAM SHELL) low altitude detection radar on a 23.8 meter mast to provide better performance in areas with varied terrain or vegetation. The shadow cast by the southern 5P85 TEL seems to indicate that it is a 5P85S, complete with the control compartment for controlling the adjacent 5P85D TEL. The vehicle which is most likely the 30N6 engagement radar vehicle appears to have the radar array lowered in the travel configuration. Given the presence of the mobile TELs and the mobile 30N6 radar, the system present here is likely either an S-300PS or S-300PM.
The following annotated image depicts the Tolicha Peak S-300PS/PM facility:

Close examination of the terrain in the vicinity of the Tolicha Peak Electronic Combat Range would seem to display impact craters, providing further evidence that actual SAM firings may be taking place here. As the United States does not actively list any of the aforementioned SAM systems in its operational inventory, it is likely that some sort of test work does take place here. It is also possible that the associated radar systems are in fact also used against aircraft flying on the Nellis AFB Range to provide more realistic electronic combat training.
JACKASS FLATS
Jackass Flats is situated 45 miles southeast of the Tolicha Peak Electronic Combat Range, and was the home to some of the most interesting experimental programs to be conducted in the Nevada desert.
Pluto
Located on the eastern portion of Jackass Flats is the remains of one of the most interesting and potentially catastrophically dangerous weapons programs of the Cold War. Project Pluto was intended to culminate with the development of a nuclear powered cruise missile. A facility was constructed to test conceptual nuclear engine designs for Project Pluto. The vast facility consisted of three main areas. Firstly, there was a reactor assembly building where the Tory-series reactors were constructed and then disassembled for analysis post-firing. Secondly, there was a separate reactor test facility situated 2 miles from the assembly facility, where the test firings would occur. Lastly, there was a complex consisting of 25 miles of piping designed to provide the compressed air necessary for testing the reactor, as it was intended to operate as a ramjet and could not function with still air. Current imagery indicates that the piping has since been removed, but the structures remain, as does the railway which used an automated railcar to transport the test articles between the two facilities.

HENRE
Jackass Flats was home to a second nuclear-related test. The High Energy Neutron Reaction Experiment (HENRE) program used a linear accelerator to provide neutrons which would be used in a radiation measurement test program. The 1,527 foot tower used in the HENRE program was previously a resident of the Yucca Flat test area, and was employed in the BREN program. It was relocated to Jackass Flats to support the HENRE program in 1966.

NRDS
The Nuclear Rocket Development Site (NRDS) at Jackass Flats was used to test nuclear rocket engines under the auspices of various test programs. The facility consisted of numerous structures, including the Reactor Maintenance, Assembly, and Disassembly (R-MAD) and Engine Maintenance, Assembly, and Disassembly (E-MAD) stations. There were three test stands, Test Cell A, Test Cell C, and Engine Test Stand 1 (ETS-1). Rocket engines, much like those tested at the Pluto facility, were transported using an automated rail system.
The following annotated image provides an overview of the NRDS:

Test Cell A was the location for the Kiwi-TNT destructive test which consisted of the obliteration of a nuclear rocket engine to simulate a potential accident during launch of a nuclear-powered rocket.
