Tyler Hersko. It seemed like a wholesome and fun proposition: Move out of bustling and expensive Los Angeles, resettle in a custom-designed tiny house in Nashville and get the experience documented on a popular television show. The tiny house movement is a relatively recent phenomenon where individuals or families move into homes that are often only a few hundred square feet in size.
Typical perks of the compact living arrangement include cheaper costs, simplicity, and environmental friendliness. They decided to reach out and hire Bedsole for the construction project because he claimed to use a healthy home kit, which includes nontoxic building materials, including wall installations.
According to the Richards, that was the first sign of trouble. The Richards also said that Bedsole did not using the healthy home kit during construction and was creating what they perceived to be other budget discrepancies. Eventually the Richards discovered that Bedsole was being evicted from the property, and they said the property owner informed the couple that the Richards needed to remove their home from the property because the trailer it sat on did not belong to them.
Swafford considered the couple to be tenants and ordered them to vacate the property. A representative of the Bradley County General Sessions Court, where the case was heard, confirmed the ruling. Ben said they found an online listing for the home via a third party, who told the couple that Bedsole approached him about selling the house. Tiny Houses For Sale. Little Houses.

And that water is freezing! Defense Secretary Robert M. Gates and wife Becky are greeted by Air Force Lt. Dana T. The Pacific Regional Medical Center moved from Clark to Elmendorf and construction of a new, greatly expanded hospital began in In , the 21st Tactical Fighter Wing was reorganized as an objective wing and all the major tenant units on Elmendorf were placed under it.
This was in keeping with the Air Force's polices of retaining the oldest and most illustrious units during a period of major force reductions. It was also an alternative landing site for the Space Shuttle. Gates talks to U. Army Col. George Bond, Missile Defense Agency's top officer at the ground based interceptor missile facilities in Alaska, June 1, DoD photo by U. Air Force Master Sgt. Gates climbs down into a ground-based interceptor missile silo on Fort Greely, Alaska, June 1, Despite this you probably never heard of it nor the Army National Guard Soldiers who "pull the lanyard.
There is one system operated by the Army National Guard however, that dwarfs any of its nearest competitors. The GMD system is the ultimate "smart weapon. In order to do this the missile must reach an escape velocity of more than 6. This hypersonic speed is several times what a 7. To put it another way, it reaches a speed of approximately Mach From there, the EKV seeks out the target using multi-color sensors, a cutting-edge onboard computer, and a series of rocket motors used for independent steering in space.
The EKV homes in on its target with pinpoint accuracy and destroys it using nothing more than the force of a massive collision hit to kill without the need of a traditional warhead or explosives. It is like hitting a bullet with a bullet, but these bullets are launched thous- ands of miles apart and are moving at Mach It is ferociously complicated, but it works. Here's why. GMD is a "system of systems" involving shooters, sensors, and Command, Control and Communication systems.
Navy warships, and the massive sea-based X-band Radar. They are responsible for the strategic and tactical level execution of the GMD mission and provide security forces to defend the assets at Fort Greely, Alaska. The Soldiers of the th Missile Defense Brigade are part of a very unique multi-component organization. The th is tasked with conducting a presidentially-directed national security mission to defend the United States against the threat of ICBM attack.
In order to perform their federal mission, all th MDB National Guard Soldiers ope-rate in a "dual status" allowing them to automatically transition between Title 10 fede-ral Active Duty and Title 32 National Guard status. The Soldiers seamlessly transition between these two statuses depending on the duties they are performing or location. Cragon and Henry N. PetersonThis invention relates to control of a radar involving microwave modular an-tenna, and more particularly to digital phase shift control of a multielement phased array antenna.
This invention is particularly advantageous in connection with the construction and operation of airborne radar, but also has important application in ground based and ship based systems. With this invention, the radar may be operated in any one of the above modes or in several of such modes on a time-sharing basis. Airborne radar systems inherently have a problem of generating high power microwave energy and processing the transmitted and received signals while maintaining high reliability and minimum weight.
Major reliability problems in radars have been concerned with components such as rotary joints, servomotors for the antennas, and the like. Restrictions imposed by such components on reliability exist in the most contemporary transistorized radars. Further, the use of magnetrons for transmitting, klystrons for local oscillator service, and use of high power transmit-receive TR protection devices, all have been found to restrict the reliability of the system.
The present invention is directed to an improved radar which may employ solid-state circuitry so constructed that major obstacles heretofore encountered in the development of solid-state radar may be overcome. A solidstate functional electronic module has been developed for construction of a modular antenna array responsive to beam steering control disclosed in application Ser. Cooke, et al.

Air Force identifies and tracks objects in space. Click and PlayBelow is an aerial view of the U. The flexibility and sensitivity of the system will provide coverage of deep space geosynchronous orbits while maintaining the survellance fence. Pic: Lockheed Martin. Click and PlayWith critical design review completed, the Space Fence team is focused on production of technology that will bring the system online.
Space Fence will use Gallium Nitride GaN powered S-band ground-based radars to provide the Air Force with uncued detection, tracking and accurate measurement of space objects, primarily in low-earth orbit. Lockheed Martin engineers and U.
Air Force personnel are testing and training on a scaled-down version of the system in Moorestown NJ known as the Integration test Bed. The ITB provides the operational context to integrate and test end-item hardware and software prior to installation in the new Space Fence facility on Kwajalein.
The locations and higher wave frequency of the new Space Fence radars will permit the detection of much smaller microsatellites and debris than current systems. The flexibility and sensitivity of the system will provide coverage of deep space geosynchronous orbits while maintaining the surveillance fence. The radar is located in Eglin, Florida and thus sometimes referred to as the Eglin Radar at about Its construction began in , but it was destroyed by fire in before becoming fully operational.
It was rebuilt and began operations in The radar was originally intended only for space surveillance, but in it was also assigned a submarine-launched ballistic missile warning mission. This choice also facilitated simultaneously obtaining multiple narrow receive beams for more precise tracking and a broader transmit beam more suitable for surveillance.
Its center frequency is MHz, with a 10 MHz bandwidth. Its wavelength is thus about 0. The transmit antenna is uniformly illuminated and has a 1. Each of the 5, transmitter element is rated for a peak power of 10 kW and a 0. These give an array peak power of 52 MW and an average power of kW. However, according to a paper the average power of individual elements individual elements varied from 2. The receive antenna is a tapered array with a diameter of 58 m containing 19, crossed dipole elements on a square grid, forming a circular aperture elements in diameter.
There are active receive modules. Its receive beam width is 0. The combined beam width is therefore 0. All nine receive beams are used in search, but only five in track. The FPS operates in time blocks called resource periods, each of which is 50 ms long. Its maximum bandwidth is 10 MHz. The pulse compression used to obtain greater better range resolution ratio may be as large as 1, OperationsThe FPS initially conducted surveillance using several different radar fences.
A software upgrade left the FPS with only relatively low-elevation radar fences, as the software needed for a higher-elevation fence intended for detecting lower RCS space objects was not funded. By integrating large numbers of pulses, the FPS is capable of tracking previously detected objects at least out to geosynchronous orbit range. It is the only phased-array radar in the U. Space Surveillance Network capable of tracking objects in geosynchronous orbit the next two largest phased arrays are not oriented so as to be able to view geosynchronous orbit.
The FPS assumed a deep space role in November after receiving a range-extension upgrade enabling integration of many pulses. The sensors are a conglomeration of capabil- ities mostly derived from and shared by other missions. Few of the sensors were developed for the express purpose of conducting space surveillance.
The Air Force has recognized that providing warfighters with effective Space Situational Awareness SSA requires a coordi-nated architecture-based approach to establishing and maintaining sensor capabilities. The satellite was built by a team made up of Boeing prime and Ball Aerospace space vehicle. The development and production contract provides for satellite design, fabrication, delivery, and launch, as well as ground station delivery and post-launch support. SBSS will track objects primarily in deep space orbital period greater than minutes.
However, SBSS will also have the capability to track objects with shorter periods, illumination permitting. The SBSS payload consists of a visible sensor assembly, a gimbal, and payload deck electronics. MIT Lincoln Laboratory is providing program management, integration, supervision of facility construction, and the telescope camera. L-3 Integrated Optical Systems is building the telescope. In , the U. It will be a dedicated sensor in the U.
The tele-scope is designed to find, fix, track, and characterize faint objects. It is the most dynamically agile telescope of its size ever built. It provides the first major technology push for deep space surveillance in over three decades. The powerful device will be built in Exmouth as part of an agreement between Australia and the United States.
It will contribute to the US global Space Surveillance Network, which provides warnings to all satellite operators of potential collisions with other satellites or debris. David Johnston, Defense Minister Australia The construction costs of the telescope will be shared and it will be located at the Harold Holt naval communications facility.
Defence Minister David Johnston says the telescope will focus on protecting satellites from space junk and will be operating in And here we are. Below is transcript of the radio talk with Defense Minister David Johnston. While the telescope will track asteroids and space debris, the Australian Defence Minister insists it will not be used for spying, despite having the ability to do so. The telescope has been moved to the Harold Holt naval communications facility at Exmouth.
Here's AM's Caitlyn Gribbin. Now, it's getting a space surveillance telescope. They came to us and we said well why don't we put it at Exmouth? And they said that's a good idea. The construction costs will be shared and the telescope, which will monitor space debris, will be operating in Those radio waves reflect off bits of space junk and the reflected waves are received by the telescope.
And the telescope basically tracks the space junk, predicts its orbit and is there to try and help prevent collisions between the space junk and satellites. Senator Johnston says it's in the national interest to build the telescope in WA. Do you have any concerns about that? I'm very much aware that this is for the general use of satellites that are largely civil in their output. It was a very short document. It was about the surveillance of space debris. It doesn't look at Earth.
It looks out from Earth into the outer atmosphere so that it's, you know, it's focused on things that are in the line of travel of satellites. So broadly speaking, it's in the same class of instruments but its specific purpose is to do radar for space junk. The telescope is still under construction. SST will see first light in late DARPA testing will occur in and It provides timely and accurate metric tracking and space object identification data.
Although primarily a near-Earth sensor, it is the only dedicated, high-capacity phased array radar with both near-Earth and deep-space capability. It is the primary tracker of low-inclination objects, and of objects that transit the manned-spaceflight regime. It has the capability to track most near-Earth objects once per day. This makes the operation of the FPS critical to the safety of manned space-flight.
The SLEP will extend the operation of the radar until and will provide the ground work for future updates to the radar. Haystack operates today at X-band, with one GHz of bandwidth. The upgrade will add the capability to operate at W-band with eight MHz of bandwidth. This will enable finer characterization of satellites, and characterization of smaller satellites than possible today.
Operation at W-band requires replacement of the current Haystack antenna. Because of this, Haystack will be down from operations from May until August A smaller antenna, which is being used to test the W-band RF components, is producing images and will be available for limited operations during this time. It provides the most accurate tracking of any space surveillance radar. Radar development began in The radar was fielded in Norway in , making it 11 years old at IOC.
Extended down-times for emergency maintenance are expected in the time frame. The US needs to provide effective protection for space systems. The first step in doing this is to provide effective tactical and strategic situ-ational awareness. This is the most effective and efficient way to integrate a variety of sen-sors and other instruments on a broad set of satellites.
SASSA will begin with a tech-nical demonstration and will proceed with methodical risk re-duction activities over the subsequent several years. It will produce an integrated set of flight hardware that will be operated on-orbit, providing a test bed to allow continued interface testing with new instruments. The interface specification will be developed to enable future technology investments. It will establish policy for future space protection activities.
SASSA will end with a finalized busi-ness strategy to guide future activities. An eventual SASSA acquisition program and beyond will encompass full-scale production of a standardized protection capability. The goal is integrated on-board awareness and protection capabilities for all US space systems.
As the foundation for space control, SSA encompasses intelligence on adversary space operations; surveillance of all space objects and activities; detailed reconnais-sance of specific space assets; monitoring space environmental conditions; monitoring cooperative space assets; and conducting integrated command, control, communications, processing, analysis, dissemination, and archiving activities. Program Element F, Space Situational Awareness Operations, fields, upgrades, operates and maintains Air Force sensors and information integration capabilities within the SSA network while companion program element F, Space Situation Awareness Systems, develops new network sensors and improved information integration capabilities across the network.
Activities funded in the SSA Operations program element focus on surveillance of objects in earth orbit to aid tasks including satellite tracking; space object identification; tracking and cataloging; satellite attack warning; notification of satellite flyovers to U. Forces; space treaty monitoring; and technical intelligence gathering.
The bombers can carry various modifications of the Kh, AS and Kh cruise mis-siles and gravity bombs. Russia operates two satellites of the new-generation early-warning system, EKS, and a network of early-warning radars. The satellite, Cosmos, is currently undergoing tests. Second spacecraft, Cosmos, was launched in May The early-warning satellites were transmitting information in real time to the Western command centers at Serpukhov, near Kurilovo, Kaluga oblast and Eastern center near Komsomolsk-on-Amur.
The information is processed there and transmitted to the command center in Solnechnogorsk. The main command center of the system and the battle-management radar are located in Sofri-no Moscow oblast. The command center of the system and its radar are undergoing a soft- ware upgrade. The system includes the Don-2N battle-management phased-array radar, command center, and 68 short-range interceptors of the 53T6 Gazelle type.
The 32 long-range 51T6 Gorgon interceptors have been removed from the system. The short-range interceptors are deployed at five sites -- Lytkarino 16 interceptors, Sofrino 12, Korolev 12 Skhodnya 16, and Vnukovo Long-range missiles used to be deployed with two units with headquart-ers in Naro-Fominsk and Sergiyev Posad The system was accepted for service in Space surveillanceSpace surveillance system is operated by the Main space-surveillance command center.
To monitor objects on low earth orbits and determines parameters of their orbits, the system uses the the early-warning radar network. The space surveillance network also includes the Krona system at Zelenchukskaya in the North Caucasus, which includes dedicated X-band space surveillance radars.
Another system of this type is being deployed near Nakhodka on the Far East. To monitor objects on high-altitude orbits, the space-surveillance system uses optical obser-vations. The main optical observation station, Okno, is located in Nurek, Tajikistan. Its tele-scopes allow detection of object at altitudes of up to 40, km. The station began operat-ions in Space-surveillance tasks are also assigned to observatories of the Russian Aca-demy of Sciences.
In addition, three radars--Baranovichi, Murmansk, and Pechora--have been "upgraded. Barnaul and Yeniseisk are Voronezh-DM. The radar in Baranovichi which is in Belarus is an old one-of-a-kind Volga radar. The Daryal radar in Pechora is even older - it's one of the two original Daryal radars built in the s.
Construction of new radar, probably of the Voronezh-VP kind, began there earlier this year. As we can see, the upgrade of the early-warning radar network has been a very successful program. The space segment of the early-warning system, in contrast, appears to be behind the schedule. It appears to be undergoing tests. The new armament program calls for deployment of ten satellites of the EKS system by , but this plan does not seem particularly realistic.
It should be noted, however, that for Russia the space-based segment of the early-warning system is not as as critical as for the United States, since it could never really rely on the "dual phenomenology" approach adopted by the United States. This is illustrated on this figure: It shows that in some scenarios SLBMs launched from the Atlantic, satellites don't add much to the warning time.
In any event, since Russia doesn't have forward-deployed radars, the radar warning comes to late to provide a useful check of the satellite informa-tion. To deal with the situation, the Soviet Union developed a different mechanism that allowed it to wait for signs of the actual attack such as nuclear explosions before launching its missiles. The arrangement is often referred to as the Dead Hand, since it does involve a certain predelegation of authority as well as the mechanism that ensures that decapitation does not prevent retaliation.
The system, however, is not automatic that idea was nixed in the s and requires humans to be involved in the decision to launch. Located in the Push- kino district of Moscow it is a quadrangular truncated pyramid 33 metres ft tall with sides metres ft long at the bottom, and 90 metres ft long at the top. Each of its four faces has an 18 metres 59 ft diameter Ultra high frequency band radar giving degree coverage. The system is run by an Elbrus-2 supercomputer.
It has a range of km for targets the size of a typical ICBM warhead. The first radar, in Lekhtusi near St Petersburg, became operational in There is a plan to replace older radars with the Voronezh by The Voronezh radars are described as highly prefabricated meaning that they have a set up time of months rather than years and need fewer personnel than previous generations.
They are also modular so that a radar can be brought into partial operation whilst being incomplete. At the launch of the Kaliningrad radar in November Russian President Dmitry Medvedev was quoted as saying "I expect that this step [the launch of the radar] will be seen by our partners as the first signal of our country's readiness to make an adequate response to the threats which the missile shield poses for our strategic nuclear forces.

This new direction for European missile defense broke with the plans pursued by the Bush administration. The Bush plans had called for deployment of a ground-based missile defen-se system in Europe, similar to the system deployed in California and Alaska. This included bilateral agreements to station ground-based interceptors in Poland and a radar installation in the Czech Republic.
This represented "the first sustained deployment of a ballistic missile defense-capable ship" in support of the European PAA. The SM-3 IA succesfully intercepted a medium-range ballist missile target in its most recent test on February 13, Block IA has a single color seeker, a 21 inch-diameter booster, and is Block IA costs between 9 and 10 million per unit.
Sensors and Combat SystemInitially, the system will use sea-based sensors mounted on the Aegis ships, as well as a forward-based mobile X-band radar on land. The U. So far, seven have been produced, and two are currently deployed in Israel and Japan. The sensors and interceptors will be brought together under the Aegis combat system. This is a system capable of tracking simultaneous targets. Phase 1 will primarily use Aegis version 3.
Interceptors will also be mounted on an increasing number of Aegis BMD ships. In FY, the U. Navy plans to have 32 Aegis BMD ships. This interceptor differs from the Block IA in its "seeker" technology, consisting of a two color seeker, or "kill warhead," and improved optics. The Block IB is estimated to cost between 12 and 15 million per unit. Sensors and Combat Systems In Phase 2, sensors will be integrated with updated versions of the Aegis combat system. This will supplement the deployments already underway at sea and in Romania and will extend coverage over a greater percentage of Europe.
This new variant will be faster than Block I 4. These faster interceptors could potentially increase coverage to the whole European continent. The program is scheduled to begin flight testing in Improved seeker and optics will be included. Aegis BMD ships are scheduled to be equipped with version 5. Was planned to have an improved seeker and a higher performance booster, with a velocity of According to the Defense Science Board , the SM-3 IIB's planned mission to intercept targets prior to the deployment of multiple warheads or penetration aids — known as "early intercept" — requires "Herculean effort and is not realistically achievable, even under the most optimistic set of deployment, sensor capability, and missile technology assumptions.
Category and DescriptionPresident George W. Bush announced Dec. As of February , the U. The United States also possesses 18 warships equipped with Aegis Ballistic Missile Defense, a system intended to counter short- and intermediate-range ballistic missiles as of January Developing and deploying ballistic missile defenses ranked high among the priorities of the George W. Bush administration.. The administration also aggressively sought foreign partners for the U.
Still, the technology remains unproven. Intercept tests have involved substitute components in highly scripted scenarios. In thirteen tests, the Pentagon has hit a mock warhead eight times. In the most recent test, conducted on December 5, , the interceptor successfully destroyed the mock warhead; however, the incoming missile failed to deploy countermeasures meant to fool the interceptor into missing its target. Pentagon officials acknowledge that the initial system will be rudimentary.
But they argue that some defense is better than none at all. In addition, they assert that the only way to conduct more strenuous and realistic testing of the system is to deploy it.. For more than five decades, the United States has intermittently researched and worked on missile defenses. The planned deployment this fall will mark the second time that the United States has moved to deploy a defense against long-range ballistic missiles. The first effort, Safeguard, was shut down within a few months of being declared operational in October because Congress concluded the defense was too expensive and ineffectual.
Missile base located in North Dakota. The Bush administration inherited seven main missile defense programs, including the ground-based missile interceptor system and two related satellite programs. For the most part, the Bush administration continued work on these same programs, although it recast some, cut others, and added new projects.
It canceled one sea-based system—the Navy Area Theater Ballistic Missile Defense System—and significantly down-sized a space-based laser initiative, while commencing new efforts to develop interceptors to attack multiple targets and to strike enemy missiles early in their flights. During the Clinton administration, Republicans repeatedly asserted that the development of working missile defenses was being hindered by a lack of political will, not scientific or engineering challenges.
However, several missile defense programs have fallen further behind schedule and suffered setbacks due to technical difficulties under the Bush administration. An aircraft designed to be armed with a powerful laser—known as the Airborne Laser—is now more than two years behind schedule and may be shelved. One of the two inherited satellite programs has been overhauled and renamed, while the other has far exceeded cost and schedule estimates.
In general, the Bush administration reorganized missile defense programs, placing all of them under one big tent the Missile Defense Agency rather than working on each one in isolation. Nevertheless, the Pentagon maintains individual program offices for each system, albeit with an eye toward sharing technology among the systems and exploring how they might operate together. In addition, the Pentagon is actively pushing to expand some of the earlier theater missile defense programs to try and tackle the strategic mission.
ICBMs travel farther, faster, and are more likely to employ countermeasures intended to fool defenses than shorter-range missiles. The ABM Treaty permitted the development of theater missile defense systems but prohibited work on nationwide strategic defenses. At this time, only the ground-based interceptor system has been tested against strategic ballistic missile targets, although the Pentagon has started to investigate whether some radars and sensors used in theater systems might also be capable of tracking a strategic ballistic missile.
Preliminary findings are encouraging, according to the Pentagon, which has declined to provide specific test results. The Obama administration has expressed general support for the idea of national missile defense, but indicated that some Bush-era programs may be up for review. Also included are Pentagon estimates on when each defense may have an initial, rudimentary capability as well as when it could be fully operational.
Ballistic Missile BasicsBallistic missiles are powered by rockets initially but then they follow an unpowered, free-falling trajectory toward the target. There are four general classifications of ballistic missiles:Short-range ballistic missiles, traveling less than 1, kilometers approximately milesMedium-range ballistic missiles, traveling between 1,—3, kilometers approximately , milesIntermediate-range ballistic missiles, traveling between 3,—5, kilometers approximately 1,, milesIntercontinental ballistic missiles ICBMs, traveling more than 5, kilometersShort- and medium-range ballistic missiles are referred to as theater ballistic missiles, whereas ICBMs or long-range ballistic missiles are described as strategic ballistic missiles.
The ABM Treaty prohibited the development of nationwide strategic defenses, but permitted development of theater missile defenses. Ballistic missiles have three stages of flight:The boost phase begins at launch and lasts until the rocket engines stop firing and pushing the missile away from Earth. Depending on the missile, this stage lasts between three and five minutes. During much of this time, the missile is traveling relatively slowly, although toward the end of this stage an ICBM can reach speeds of more than 24, kilometers per hour.
The missile stays in one piece during this stage. The midcourse phase begins after the rockets finish firing and the missile is on a ballistic course toward its target. During the early part of the midcourse stage, the missile is still ascending toward its apogee, while during the latter part it is descending toward Earth. This stage takes less than a minute for a strategic warhead, which can be traveling at speeds greater than 3, kilometers per hour. Short- and medium-range ballistic missiles may not leave the atmosphere, have separating warheads, or be accompanied by decoys or other countermeasures.
The EKV destroys its target by colliding with it. This process is referred to as hit-to-kill. StatusTo date, the system has had eight successful intercept attempts in twelve developmental tests. The most recent test, on Dec. Another 10 interceptors are to be deployed at FortGreely before the end of There are no plans to fire interceptors from FortGreely for testing purposes.
The interceptors under the Clinton plan were to have been supported by a land-based X-band radar, but the Bush administration also developed a sea-based X-band radar SBX. SBX was used on Dec. This radar, known as the Cobra Dane radar, is only be able to track missiles fired from the direction of Asia because the radar is fixed to face northwest.
MDA is also exploring the construction of a third missile defense site in Europe. The Bush administration signed a deal with Poland on August 20, , to place ten missile interceptors on Polish territory. The Bush administration also won the approval of the Czech government on April 3, , to build a tracking radar facility in the CzechRepublic.
The United States is upgrading two foreign-based, early-warning radars to help track ballistic missiles launched from the direction of the Middle East. Fylingdales has been upgraded and is operational, while the Thule-based radar will be integrated into the missile defense system by the end of fiscal year The SM-3 is a hit-to-kill missile comprised of a three-stage booster with a kill vehicle.
The SM-3 is considered too slow to intercept a strategic ballistic missile. Designed to CounterInitially, the Aegis BMD is geared toward defending against short-, medium-, and intermediate-range ballistic missiles during their midcourse phase with an emphasis on the ascent stage. StatusThe system has a record of fourteen intercepts in eighteen flight tests. The two most recent tests, both in November , were failures. In a November 1 test, two target missiles and two interceptors were launched from Aegis-equipped destroyers in the Pacific Ocean.
One interceptor hit its target, but the other did not. In another test, on November 19, , the interceptor lost track of its target seconds before impact. Navy has eighteen ships outfitted with the Aegis BMD system. Sixteen of these ships are deployed in the Pacific Ocean, leaving two in the Atlantic. Between and , the Navy hopes to build an Aegis force of 84 ships: 22 cruisers and 62 destroyers. The laser beam is produced by a chemical reaction.
Designed to CounterAlthough the Pentagon originally aimed to field the ABL against theater ballistic missiles, the Pentagon now contends the ABL may have an inherent capability against strategic ballistic missiles as well. The expanded ABL objective is to shoot down all ranges of ballistic missiles in their boost phase. The plane was not equipped with the laser. By , an ABL test plane had successfully tracked a target and hit it with a low-power laser.
The target was not a ballistic missile, however, but was mounted on another aircraft. Although Clinton administration plans first projected an ABL intercept attempt to take place in , development delays have led the Pentagon to push back such a test several times. It is now expected to take place in THAAD missiles are fired from a truck-mounted launcher. Intercepts could take place inside or outside the atmosphere.
StatusThe system had two successful intercept attempts in the summer of after experiencing six test failures between April and March THAAD has tested successfully five times since being redesigned. In two other tests the interceptor was not launched due to malfunctions of the target missiles.
The missile is guided by an independent radar that sends its tracking data to the missile through a mobile engagement control station. StatusDuring earlier developmental testing, the system struck nine out of 10 targets. In four, more difficult operational tests between February and May that involved multiple interceptors and targets, seven PAC-3s were to be fired at five targets. Of the seven PAC-3s, two destroyed their targets, one hit but did not destroy its target, one missed its target, and three others did not launch.
PAC-3s destroyed two Iraqi short-range ballistic missiles during the conflict and shot down a U. Fighter jet.
