US Restricted and Classified Test Sites

INTRODUCTION

The widespread availability of open-source overhead imagery thanks to applications like Google Earth and NASA World Wind has provided the public with the chance to view many restricted and classified test locations within the United States. While details of the test programs associated with some of these facilities are obviously not going to be discernable, the availability of open-source imagery nevertheless allows individuals to view sensitive facilities that normally would be hidden by terrain, and sometimes heavy security.

This article is not intended to be an all-inclusive list of classified test facilities, nor an in-depth examination of Area 51, but rather an overview of some of the most significant and interesting test sites in the country.

RCS RANGES

Some of the most significant defense-related facilities in the United States are Radar Cross Section (RCS) test ranges. These facilities, being either contractor or government operated, conduct some of the most sensitive test programs in the defense industry. RCS ranges are used to test the radar signatures of various objects, most significantly with the aim of measuring their ability to evade radar detection against various radar types. Stealth platforms like the HAVE BLUE were tested at an RCS range in order to validate the design before flight testing, for example, to ensure that the RCS of the aircraft would meet the requirements of the test program. Due to the sensitive nature of the testing conducted at these facilities, they are typically located in isolated areas.

The primary outdoor RCS test ranges can be located at the following coordinates:

Boardman: 45°44'53.55"N 119°47'10.02"W
Grey Butte: 34°34'13.01"N 117°40'11.27"W
Helendale: 34°49'30.40"N 117°17'45.83"W
Junction Ranch: 36°02'15.81"N 117°30'10.69"W
Kirtland AFB: 34°57'33.77"N 106°29'59.27"W
RATSCAT: 33°10'59.71"N 106°34'23.81"W
Tejon: 34°55'27.49"N 118°31'44.76"W

The following image depicts the relative locations of the various outdoor RCS test ranges listed above:


Boardman

Located in an isolated area west of Boardman, Oregon, the Boardman RCS range is owned and operated by Boeing. The facility consists of a radar array at the west end and a pylon for mounting test articles at the east end. The pylon can be covered by a large, moveable hangar, to protect sensitive test objects from view. When RCS testing is ongoing, the hangar slides out of the field of view of the radar sensors on a set of rails. The sliding shelter concept is similar to what was used at the former Grey Butte RCS test range.

The following image depicts the Boeing Boardman RCS test range:


Grey Butte

The former Grey Butte RCS test range is located 25 miles south by southeast of Edwards AFB in California. The Grey Butte facility was operated by McDonnell Douglas in the past, before being acquired by Boeing when the two companies merged. In 1999 the facility was closed down, being sold to General Atomics, who currently uses the facility to conduct UAV research. The former RCS test range consisted of a primary antenna array at the west end, with various target positions scattered around the range. The primary RCS test article position was directly east of the antenna array, and was hidden by a retractable hangar, which may have inspired Boeing to use a similar system at their Boardman facility.

The Grey Butte facility is interesting insofar as the location of the aforementioned retractable hangar is concerned. At the Boardman facility, the hangar retracts southeast to place the structure outside the field of view of the radar being used to measure the test article's signature. In the Grey Butte facility, the hangar retracted directly aft of the test article's location. This is interesting because it would seem to indicate that the hangar was still within the field of view of the radar arrays targeting the test article. There are two possible explanations for this apparent discrepancy. First, radar sets with a very narrow beamwidth may have been employed. This would have allowed them to target the RCS test article, with any extraneous radar energy simply passing it by and travelling straight through the open hangar bay. The second possibility is more abstract, and far less likely, although it does raise some interesting questions. It is known that the Russian defense industry has been experimenting with ionized plasma as an RCS-reduction method. A similar system (or some other RCS-reduction method) could, in theory, have been employed at Grey Butte to hide the hangar structure.

The following annotated image depicts the former Grey Butte RCS test range:


Helendale

Lockheed Martin's Helendale RCS test range, situated 32 miles east by southeast of Edwards AFB, is one of the most storied RCS test ranges in the country. The range area consists of an antenna array at the southern end, with two secondary target positions situated 425 meters and 1520 meters downrange. The primary test article facility is a large structure situated 2300 meters from the radar array. This is a large, underground complex, with a sliding roof hiding the retractable primary test pylon. A mobile radar antenna is also present, which moves off to the west when not in use to allow the radar sensors to the south a clear field of view to measure the primary test article.

The following annotated image depicts Lockheed-Martin's Helendale RCS test range:


Tejon

The Tejon RCS test range is owned and operated by Northrop-Grumman (previously Northrop, before the merger). Located 35 miles west of Edwards AFB, the Tejon RCS range consists of two separate, co-located facilities. The older, larger north complex features an antenna array and four target positions, while the newer south complex features two separate antenna-target combinations.

The following annotated image depicts Northrop-Grumman's Tejon RCS test range:


Not all RCS test ranges are operated by private contractors. The US DoD operates three outdoor RCS test ranges in California and New Mexico.

Junction Ranch

The Junction Ranch RCS test range is operated by the US Navy. It is situated on the massive China Lake range complex, located 27 miles north by northeast of China Lake NWC.

The following annotated image provides an overview of the USN's Junction Ranch RCS test range:


Being a US Navy complex, the Junction Ranch RCS range has a few unique features. Firstly, there are two separate test sites. The "dry" site is a conventional RCS test range employing a radar array and pole-mounted test objects.

The following annotated image depicts the "dry" RCS test range at Junction Ranch:


The second range is unique in that it is a "wet" facility, designed to test replicas of seagoing objects which are mounted in a water pool. Three miles to the southeast a radar facility is located atop the surrounding mountains to enable RCS testing of objects placed in the pool. Both of these locations are depicted in the overview image above.

RATSCAT

The RATSCAT Advanced Measurement System (RAMS) site is located 35 miles northwest of Holloman AFB, New Mexico. RAMS represents the most advanced low-RCS test range in the country, and as such is isolated in the White Sands Missile Range. Holloman AFB is also home to various other RCS test facilities operating under the direction of the National RCS Test Facility, with the capability to measure both pole models and in-flight models or aircraft.

The following image depicts the RATSCAT Advanced Measurement System site:


Kirtland AFB

Kirtland AFB in Albuquerqe, New Mexico is also the home to an unidentified RCS test facility. Some sources indicate that the facility may be associated with the Sandia National Laboratory, which also operates some facilities on the Kirtland range.

The following image depicts the RCS test range located on the Kirtland AFB range:


There are two other significant outdoor RCS facilities visible in the United States. They are associated with one of the most secretive military installations on the planet.

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.

The following annotated image depicts the main test area at the Tonopah Electronic Combat Range:


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 (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 5N63S (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 5N63S engagement radar vehicle appears to have the radar array lowered in the travel configuration. Given the presence of the mobile TELs and the mobile 5N63S radar, the system present here is likely either an S-300PS or export-standard S-300PMU.

The following annotated image depicts the Tolicha Peak S-300PS 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.

The following annotated image depicts the Project Pluto facilities at Jackass Flats:


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.

The following image depicts the HENRE test tower at Jackass Flats:


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.

The following annotated image depicts one of the engine transportation railcars remaining at the E-MAD facility:

SSBN Home Ports In Imagery

INTRODUCTION

Some of the most guarded military facilities in the world are the homes to nuclear missile submarines. These bastions of nuclear warfighting power represent the homes of the most powerful weapon systems ever conceived. It should be noted that only operational bases will be discussed herein; support facilities, construction yards, and other facilities are outside the scope of this article.

THE SSBN

An SSBN is a nuclear-powered submarine designed to carry and launch a number of nuclear-armed ballistic missiles. SSBNs act as the seagoing component of their operators nuclear deterrent force. The advantage of an SSBN lies in its inherent survivability through stealth. SSBNs are notoriously hard to locate when in their patrol areas and are the perfect counterforce weapon in a nuclear conflict. The mere presence of an SSBN at sea may be enough of a deterrent to ward off a nuclear exchange, as a retaliatory strike is all but guaranteed. A modern SSBN using depressed-trajectory weapons can also provide a legitimate first-strike capability, bestowing little or no warning on a targeted nation and increasing the odds that a crippling, decisive first strike can be a successful nuclear warfighting option. It should come as no suprise that the five nations employing SSBN fleets are also the five permanent members of the UN Security Council.

UNITED STATES

The United States operates two SSBN facilities, one serving each coast. The Pacific coast facility is located at Bangor, Washington, with the Atlantic coast facility being located at Kings Bay, Georgia.

Bangor

The Bangor, Washington SSBN facility consists of five main dockside areas. The southernmost facility, the KB docks, are only used to service and house support craft which service the SSBNs. SSBNs themselves tie up pierside at either the Delta Refit Pier, or the Marginal Wharf. Weapons loading is carried out at a dedicated covered dock, and a degaussing facility is also present.

The following annotated image depicts the locations of the relevant facilities at the Bangor SSBN base:


The following image depicts the Delta Refit Pier, where three Ohio-class SSBNs can be seen:


The following image depicts an Ohio-class SSBN returning to the Bangor facility via the Juan De Fuca Strait:


Kings Bay

The Kings Bay SSBN facility consists of four main dockside areas. There is a primary pier for supporting submarines in port, a drydock facility, and a degaussing facility. There are also two weapons loading facilities, in contrast to the Bangor SSBN base, which only has one.

The following annotated image depicts the Kings Bay SSBN facility:


UNITED KINGDOM

The United Kingdom's SSBN force, consisting of four Vanguard class SSBNs, is based at HMS Neptune in the northwestern part of the nation. The facility is referred to as HMS Neptune due to the Royal Navy's practice of commisioning shore facilities as vessels in Her Majesty's Navy. Outside of military circles, however, the facility is more commonly known as Faslane.

The following image depicts the Royal Navy's SSBN facility at HMS Neptune, with two of the Vanguard class SSBNs visible pierside:


FRANCE

France's Force Oceanique Strategique controls French SSBNs, which are based at I'lle Longue, near the port of Brest. The M4 L'Inflexible class SSBNs have given way to the new SNLE-NG Le Triomphant class SSBNs, with three of the latter having been commissioned as of the end of 2007, with a fourth due in 2008.

The following image depicts the French SSBN facility, with one of the old L'Inflexible class SSBNs visible in port:


RUSSIA

Russia's SSBN force has shrank considerably since the end of the Cold War. The recent withdrawl from service of Delta I and Typhoon class SSBNs leaves only the Delta III and Delta IV still serving until the new Borey class vessels are ready for duty. One Typhoon is still active in support of the Bulava SLBM test program out of Severodvinsk, but is no longer on active duty with the Northern Fleet. The withdrawl of the Typhoons means that Litsa Guba is no longer an active SSBN facility, leaving the Russian SSBN force with two operating locations: Gadzhiyevo in the Northern Fleet, and Rybachiy in the Pacific Fleet.

Gadzhiyevo

Gadzhiyevo, located on the Kola Peninsula, is the home to the Russian Northern Fleet's SSBN force. Both Delta III and Delta IV class SSBNs are operated.

The following image depicts the Gadzhiyevo submarine base, with two SSBNs annotated:


A second Delta IV can be seen at nearby Olenya Bay, a facility which has been associated with the Gadzhiyevo SSBN fleet in some circles:


Rybachiy

Rybachiy, located near Petropavlovsk on the Kamchatka Peninsula, is the home to the remainder of Russia's operational Delta III SSBN fleet. Rybachiy is divided into two main areas, a port facility where operational SSBNs and SSNs are docked, and a maintenance facility with a floating drydock for upkeep of the Pacific Fleet submarine force stationed there.

The following image depicts the Rybachiy submarine base; closer examination of the imagery will reveal two Delta III SSBNs in residence:


CHINA

There are three primary SSBN facilities serving the PLAN, Qingdao, Xiaopingdao, and Yulin. The Qingdao facility is located near the port city of the same name, while the Xiaopingdao facility is located near the port city of Dalian. Yulin is located much farther south, on Hainan island.

Qingdao

Qingdao was the first SSBN facility to be constructed in China. It currently serves as the homeport for China's sole Type 092 Xia-class SSBN, as well as a number of SSNs. The only currently identified structure known to service the Type 092 SSBN is a large drydock facility.

The following image depicts the Qingdao SSBN base:


The following image depicts the Type 092 in drydock at Qingdao:


Xiaopingdao

Xiaopingdao is a relatively new SSBN facility associated with the new Type 094 Jin-class SSBN currently being fielded. Jin-class SSBNs have been identified at this facility in the past, and Xiaopingdao is also home to the PLAN's sole Golf-class SSB. The Golf-class SSB is employed as an SLBM test vehicle, and is currently likely supporting JL-2 SLBM trials for the Type 094 fleet. The transitory nature of Jin-class SSBN presence at Xiaopingdao, as well as the Golf-class SSB's presence, suggests that Xiaopingdao may not be home to any operational SSBNs, but may instead be a trials base where new SSBNs and SLBMs are trialled before entering operational service.

The following image depicts the Xiaopingdao SSBN facility, where the Golf-class SSB can be seen along with a Type 093 Shang-class SSN:


The following image depicts a Jin-class SSBN pierside at Xiaopingdao, from October of this year:


Yulin

Yulin is the latest naval facility to be associated with the PLAN's SSBN force. In December of 2007 images appeard on the internet of a Jin-class SSBN pierside at the Yulin submarine facility. Until this point Yulin had never been visited by nor been the home port to a Chinese SSBN. While it is possible that this represents a port of call by a new Type 094 SSBN making a long-distance sortie in Chinese waters, it is also possible that the vessel sighted there will now call Yulin home, giving China two separate operational SSBN port facilities, with both the North Sea Fleet and the South Sea Fleet having an SSBN contingent.

The following image depicts the Yulin submarine base:

Russian Strategic Aviation - An Imagery Overview

INTRODUCTION

One of the primary missions of the Russian Air Force is that of strategic warfighting. To that end, there are various facilities and aircraft around the nation performing a variety of roles in support of the strategic warfighting mission. While there have been drawdowns and force reductions in recent years, the Russian military still maintains a very robust, capable, and varied strategic warfighting air arm.

AIRCRAFT

Russian strategic air assets fall into two categories: offensive and defensive. The offensive component consists of Tupolev bombers, primarily the Tu-22M3 BACKFIRE-C theater bomber and the Tu-95MS BEAR-H and Tu-160 BLACKJACK strategic missile carriers. The defensive component consists of MiG-31 FOXHOUND interceptors and Beriev A-50 MAINSTAY AEW&C platforms. A handful of Ilyushin Il-78 MIDAS aerial refueling platforms are also in service, primarily tasked with supporting the strategic aviation fleet.

Command and control assets such as the Il-86 CAMBER are also used to support strategic warfighting, but are not within the scope of this article. These assets are based at Moscow-Sheremetyevo.

Tu-22M3 BACKFIRE-C (Visible force: 171 aircraft)
The Tu-22M3 BACKFIRE-C is the primary theater strike aircraft for the Russian military. The Tu-22M3 is employed by both Long Range Aviation and the AV-MF. AV-MF aircraft are primarily tasked in an anti-shipping role. Both air arms employ the Kh-22 (AS-4 KITCHEN) standoff nuclear missile as the BACKFIRE-C's primary armament. Kh-15 (AS-16 KICKBACK) hypersonic strike missiles can also be employed, as well as unguided gravity bombs of various sizes.

Tu-95MS BEAR-H (Visible force: 39 aircraft)
The elderly Tu-95 remains one of Russia's most important combat assets. The Tu-95MS variant is employed as a cruise missile carrier, equipped with an internal rotary launcher for six Kh-55 (AS-15 KENT) ALCMs. Initially, the Tu-95MS was available in two versions, the Tu-95MS-6 and the Tu-95MS-16. The Tu-95MS-6 was armed with the internal rotary launcher, while the Tu-95MS-16 added two hardpoints under each wing allowing for the external carriage of a further ten Kh-55s. In accordance with the START agreement, the external carriage capability was removed, essentially resulting in a force of only Tu-95MS-6 variants. At least one Tu-95MS airframe has been active at Zhukovskiy as the Tu-95MA, being responsible for advanced weapons trials. This aircraft was responsible for launching the Kh-80 Meteorit supersonic ALCMs before that program was cancelled due to development problems.

Tu-160 BLACKJACK (Visible force: 16 aircraft)
The Tu-160 BLACKJACK remains the largest combat aircraft in the world. Approximately 25% larger than it's Western counterpart, the B-1B, the Tu-160 is a supersonic, intercontinental-range cruise missile carrier. Two internal rotary launchers allow for the carriage of twelve Kh-55 ALCMs. The USSR had planned on acquiring 100 Tu-160s, but the end of the Cold War and the breakup of the Soviet Union resulted in only a fraction of that number being completed, with 19 aircraft at Priluki AB being taken over by the Ukraine after the breakup. Eight Ukrainian aircraft eventually joined the six operational Russian examples at Engels AB via a debt repayment agreement, with a further aircraft being completed at the Kazan factory. Two or three other aircraft will still be completed at Kazan, and will join the operational fleet, along with two refurbished examples taken from the Tupolev test fleet at Zhukovskiy, one of which was delivered to Engels last year. One operational Tu-160 has been lost, leaving Russia with an eventual fleet of 18 or 19 aircraft, and a current strength of 15 aircraft.

MiG-31 FOXHOUND (Visible force: 213 aircraft)
The MiG-31 FOXHOUND is a strategic interceptor tasked with defending Russia's vast airspace from inbound strategic bombers, cruise missiles, or reconnaissance aircraft. The MiG-31's primary weapon is the R-33S (AA-9 AMOS B) long-range AAM. The R-33S, a SARH weapon, is an improved version of the initial R-33 (AMOS A). The R-33S was developed alongisde an avionics upgrade for the MiG-31 as a response to American espionage which compromised the initial systems, and has a maximum range of 160 kilometers. Three versions of the MiG-31 are presently fielded: the baseline MiG-31,the improved MiG-31B which added IFR capability, and the MiG-31BS, which is a MiG-31 upgraded to MiG-31B standard. Upgrades and overhauls are performed at the factory at Nizhny Novgorod.

A-50 MAINSTAY (Visible force: 19 aircraft)
Beriev's A-50 MAINSTAY is an AEW&C conversion of the Ilyushin Il-76 CANDID transport. Incorporating a Shmel' radar system in a rotodome above the rear fuselage, the A-50 is the airborne early warning component of the strategic defense network.

Il-78 MIDAS (Visible force: 19 aircraft)
The Il-78 MIDAS is an in-flight refueling tanker based on the Il-76 CANDID transport. Russia's Il-78 force is primarily tasked to support strategic aviation due to the small size of the fleet; when the USSR broke up, a good deal of the in-service Il-78s were in the Ukraine. Two versions exist, the Il-78 and Il-78M. The Il-78 is a single-point refueling platform incorporating a drogue system in the rear fuselage. The Il-78M is a three-point refueling platform, adding two additional drogues under the outer wings.

Tu-95MS BEAR-H
-The Tu-95MS has a maximum unrefueled range of 10,500 kilometers with six Kh-55SM ALCMs. Combat radius is notionally calculated at 5,000 kilometers. Bear in mind that range and/or endurance can be increased with in-flight refueling.

The following image depicts North America. Given that the Tu-95MS is a strategic weapons platform, two range depictions are given. Orange lines depict the radius of the Tu-95MS from the three primary BEAR-H airfields, showing the closest points of approach to North America. Red lines depict the inland reach of the 3,000 kilometer range Kh-55SM ALCM. Bear in mind that the inland reach of the Kh-55SM can be increased by forward deploying the Tu-95MS to one of the three Arctic staging bases:
Tu-160 BLACKJACK
-The Tu-160 has a maximum unrefueled range of 12,300 kilometers with twelve Kh-55SM ALCMs. Combat radius is notionally calculated at 6,000 kilometers. Bear in mind that range and/or endurance can be increased with in-flight refueling.
