China’s Anti-Carrier Missile Now Opposite Taiwan, Flynn Says

The Chinese military has deployed its new anti-ship ballistic missile along its southern coast facing Taiwan, the Pentagon’s top military intelligence officer said today.

The missile, designated the DF-21D, is one of a “growing number of conventionally armed” new weapons China is deploying to the region, adding to more than 1,200 short-range missiles opposite the island democracy, U.S. Army Lieutenant General Michael Flynn, the Defense Intelligence Agency director, said in a statement to the Senate Armed Services Committee.

Flynn’s reference to the DF-21D follows one made by U.S. Navy Admiral Samuel Locklear, head of the U.S. Pacific Command, in congressional testimony on April 9. He highlighted the “initial deployment of a new anti-ship missile that we believe is designed to target U.S. aircraft carriers.”

Flynn’s brief reference to the DF-21D today is significant because it advances the DIA’s assessment last year, when U.S. Army Lieutenant General Ronald Burgess, then the agency’s director, said China’s military is “probably preparing to deploy” the weapon.

The disclosure may spark increased scrutiny in Congress this year about the vulnerability of the Navy’s aircraft carriers, including the new Gerald R. Ford class being built by Newport News, Virginia-based Huntington Ingalls Industries Inc.. (HII)

The Navy estimates that the first new carrier will cost at least $12.3 billion, and the service’s budget request for the fiscal year beginning Oct. 1 includes $1.68 billion for new aircraft carriers, more than double this year’s $781.7 million request. Of that, $945 million would pay for continued design and construction of the second Ford-class carrier, the USS John F. Kennedy.

‘Immediate Need’

Michael Gilmore, the Pentagon’s director of operational testing, warned in his January 2012 annual report that the Navy lacked a target needed to check its defenses against the DF-21D. The Navy had an “immediate need” for a test missile able to replicate the DF-21D’s trajectory, Gilmore said.

Last July, Gilmore told Navy Secretary Ray Mabus in a memo that testing to evaluate the new carriers’ “ability to withstand shock and survive in combat” would be postponed until after the Kennedy is built, and may not be completed for seven years.

The DF-21D is intended to give China “the capability to attack large ships, particularly aircraft carriers, in the western Pacific,” the Pentagon’s 2012 China report said. The report cites estimates that the missile’s range exceeds 930 miles (1,500 kilometers).

Carrier Hunters

The missiles are designed be be launched to a general location, where their guidance systems take over and spot carriers to attack with warheads intended to destroy the ships’ flight decks, launch catapults and control towers.

U.S. Chief of Naval Operations Admiral Jonathan Greenert told defense reporters in March 2012 that the Navy is evaluating how to defeat the missile during all phases of flight, using methods such as jamming the missiles’ sensors, reducing the electronic emissions from U.S. ships, and intercepting the missile.

“Some call that links of a chain,” Greenert said. “You want to break as many links as possible.”

In its fiscal 2014 Budget Highlights book, the Navy said it’s working a “kill chain” against an unspecified weapon.

The Navy, the book says, wants to integrate the capabilities of the Falls Church, Virginia-basedNorthrop Grumman Corp.’s (NOC) E-2D Advanced Hawkeye surveillance aircraft; Bethesda, Maryland-based Lockheed Martin Corp.’s (LMT) Aegis surveillance and missile defense system; and Waltham, Massachusetts-based Raytheon Co.’s (RTN) Cooperative Engagement Capability sensor network linking ships and Standard Missile-6 interceptors “to keep pace with the evolving threat.”

Analysts including Mark Gunzinger, a senior fellow with the Center for Strategic and Budgetary Assessments, and some naval officers worry that the new carriers, while formidable warships, may not be able to get close enough for their planes to attack enemies, such as China and Iran, that are armed with precision- guided anti-ship cruise and ballistic missiles.

Retired US Navy captain: The centerpiece of the Navy's future doubles down on a 20-year-old strategic mistake

Aircraft carriers are the ultimate symbol of American military dominance.

Weighing tens of thousands of tons and costing billions of dollars, these vessels allow the US to project power around the world far from its shores.

But according to a retired US Navy captain, the prime time of aircraft carriers may be coming to an end as strategic mistakes committed by the US over the past 20 years has limited these vessel's capabilities while leaving them open to strikes from new emerging threats.

Retired Navy Capt. Jerry Hendrix, writing in the Center for a New American Security, makes the case that aircraft carriers have steadily lost their utility over the past two decades.

At fault for this are twin mistakes of the US Navy: a steady introduction of aircraft with decreasing flight ranges in addition to a failure to foresee rising military capabilities from countries like China that could target carriers.

"American power and permissive environments were assumed following the end of the Cold War, but the rise of new powers, including China and its pursuit of anti-access/area-denial (A2/AD) strategies and capabilities to include the carrier-killing 1,000 nautical mile (nm) range Dong Feng-21 anti-ship ballistic missile, now threatens to push the Navy back beyond the range of its carrier air wings," Hendrix notes.

Essentially, any carrier that operates within 1,000 nautical miles of Chinese military placements could be open to a strike from an antiship ballistic missile. This would not be a problem, except that the average unrefueled combat range of US carrier air wings operates at half that distance.

And even that average combat range is a decrease from the height of the Cold War.

In 1956, for example, air wings had an average range of 1,210 nautical miles on internal fuel alone. This range was achieved even though the US Navy was using an older class of aircraft carriers that could support less aircraft than today's modern carriers.

The move to shrink the flight range of carrier air wings occurred following the fall of the Soviet Union and the Navy's decision to shift the strategic purpose of carriers away from long-range missions toward acting as platforms for faster and shorter-range sortie missions.

"[P]lanner elected to invest in lower-end conflict scenarios that foresaw carriers operating in the littoral waters nearer their targets," Hendrix wrote. "Emphasis was placed on reliability and sortie generation capabilities. In the language of strategic planners, long range was an area where the Navy and the Department of Defense decided to 'accept risk.'"

These decisions meant that the average unrefueled range of carrier air wings since 1996, at 496 nautical miles, are at their lowest point since the 1930s. In 1930, for instance, the average range was 258 nautical miles. By 1943, this range was extended to 758 nautical miles unrefueled.

And according to Hendrix, the Navy's current procurement strategy does nothing to alleviate the issue.

The decision to follow through with the F-35 only serves as "completing the retreat from range,"according to Hendrix. The F-35 was meant to replace long-range legacy aircraft such as the F-14 and the A-16 — which are no longer in service — but the F-35's initial specs of having a combat range of 730 nautical miles was a 75% decrease in capability from those aircraft.

But in actuality, the F-35C's combat range is expected to be 550 nautical miles, only 50 nautical miles longer than the Navy's current complement of F/A-18E and F Super Hornets.

This lack of range, unless the Navy changes course, will continue to mean that the Navy will have little choice but to continue to operate in waters off potential enemy coasts.

And this means that carriers, for all their cost and high-tech capabilities, would either hypothetically fall within range of Chinese antiship ballistic missiles or would be forced to operate beyond the unrefueled range of their air wings.

"Today’s Navy looks remarkably like it has for the past 70 years, just smaller and more expensive," Hendrix noted in an article for the National Review. "It is an evolutionary force, not a revolutionary force, and it's an easy target for rising powers that seek to overtake it."

A consensus seems to have developed among a large number of defense analysts in recent years arguing that despite the balance of power having shifted in China’s favor, Beijing has no intention to use its military to invade Taiwan and thus resolve the Taiwan “question” once and for all. Doing so would be too costly, some argue, while others contend that Beijing can accomplish unification by creating enough economic dependence and incentives to convince Taiwanese over time of the “inevitability” of a “reunited” China.

Why China is using lasers to take down drones

China sees the new laser technology as a way to combat possible terrorist drone attacks during "major events in urban areas."

Christian Science Monitor 

The "homemade laser defense system" specifically targets small-scale drones flying at a low altitude – the likely choice of terrorists, the official Xinhua news agency reported.

The mechanism can also take down various other small aircraft within a two-kilometer radius within five seconds of locating its target, the China Academy of Engineering Physics, one of the system's co-developers, claimed in a statement Sunday.

Recommended: The future of drones in the US

"Characterized by its speed, precision and low noise, the system is designed to destroy unmanned, small-scale drones flying within an altitude of 500 m and at a speed below 50 m/s," Xinhua said, citing the statement.

"Intercepting such drones is usually the work of snipers and helicopters, but their success rate is not as high and mistakes with accuracy can result in unwanted damage," said Yi Jinsong, a manager with China Jiuyuan Hi-Tech Equipment Corp., a group under the academy spearheading the project, according to the report.

Yi said these cheap and easy-to-use drones are feasible weapons for terrorists.

Further, drones engaged in unlicensed mapping activities have officials worrying about the effect on military and civil aerial activities.

The new laser system will be installed or transported in vehicles, and "is expected to play a key role in ensuring security during major events in urban areas," the CAEP statement said. It reported the machine had a 100 percent success rate, shooting down more than 30 drones in a recent test.

Xinhua said the academy revealed that it was working on similar laser security systems with greater power and range.

"China typically deploys tight security for domestic political meetings, international conferences and sports events, looking to prevent public protests over issues such as illegal land seizures and corruption as well as any threats to the participants," the Guardian noted.

The US military successfully tracked and brought down a surveillance drone using a similar device in 2012, and laser-based weapons have become a standard line of defense against drones since, the Verge pointed out.  

"By training a high-energy beam on the craft for long enough, the weapons are able to burn through the crafts in mid-air, and they are small enough to mount on a truck. The attack requires sustained contact with the target, making it ideal for less maneuverable aircraft like the predator drone, although similar attacks have also been proposed for destroying missiles before they reach their intended target."

Last year, the US Army successfully tested a truck-mounted laser to stop mortars and drones, destroying targets in low-level midair explosions, preventing them from exploding on the ground.

After the weapon stopped a barrage of 90 incoming mortars and several drones in mid-flight, defense officials at the Army Space and Missile Defense Command hailed it as a “big step in the development of targeted, high-energy laser beams that might also one day be used to defend USairspace against, for example, fighter-jet or cruise-missile attacks," the Monitor reported.

China unveils 'laser to shoot down low-flying drones'

China has developed a highly accurate laser weapon system that can shoot down light drones at low altitude, state media reported. The machine has a two-kilometre range and can bring down "various small aircraft" within five seconds of locating its target, the official Xinhua news agency said,…

美國默許
美國想了解東風21型飛彈!
東風21型飛彈 沙國證實購買

東風21型中程彈道飛彈首度部署在非中國的領土!沙烏地阿拉伯18日證實,已向中國購買東風21型飛彈,主要用以保衛伊斯蘭聖地麥加、麥地那及波斯灣盟國。BBC報導指出,此舉意在抗衡伊朗日益強大的導彈力量。

沙烏地阿拉伯退役少將、三軍聯席委員會顧問安華‧馬吉德‧艾思奇,在接受訪問關於沙烏地阿拉伯新的軍事採購計畫時表示,沙烏地阿拉伯已向中國採購相當數量的東風21型飛彈,但是並未說明相關型號。

東風21型中程彈道飛彈,為中國潛射彈道飛彈巨浪1型的陸基版本,於1985年試射成功,1989年進行量產,射程約在1600到2000公里間,共有甲、乙、丙、丁4種衍生型,其中東風21丁型飛彈,即為國際間盛傳的航母殺手,世界上第一款反艦彈道飛彈。

其實這並非沙國首次向中國購買彈道飛彈,今年4月份的一段關於沙國閱兵的影片中,東風3型彈道飛彈的身影赫然在目,也證實了2國間存在中程彈道飛彈的交易。

BBC於22日報導指出,美國由於以色列的安全及自身受限於中程彈道飛彈條約,因此無法提供美制導彈給予沙國。美國《外交官》雜誌分析,此次沙國向中國購買東風21型飛彈,是在美方的默許下達成,而美國唯一的條件便是不得攜帶核彈頭。

《新聞週刊》的分析則認為,由於中沙2國在能源戰略上的合作愈來愈多,而與美國的伊拉克及敘利亞政策互有矛盾,導致沙國在軍事裝備上不願依靠美國。

由於伊斯蘭聖地麥加及麥地那的加持,沙國在阿拉伯國家間具有舉足輕重的地位,也是美國在中東,除以色列外最重要的盟友之一。雖然美國與沙國當初對於敘利亞的政策上有歧見,但為應付IS威脅的盟軍成軍在即,沙國購買東風21型飛彈預料將不會影響2國的關係。

WASHINGTON (Reuters) - The U.S. Air Force said on Tuesday it had awarded Lockheed Martin Corp a fixed-price contract valued at $1.9 billion to complete work on two missile-warning satellites as part of the Space-Based Infrared System (SBIRS).

The contract, announced in the Pentagon's daily digest of major contract awards, runs through Sept. 30, 2022.

It funds completion of the fifth and sixth satellites in the SBIRS system, and includes performance incentives and options for acoustic testing, launch operations an early on-orbit testing, the Pentagon said.

U.S. Air Force Space Command's Space and Missile Systems Center said the contract award saved over $1 billion as a result of a block-buy contracting approach and production and management efficiencies.

"We eliminated unnecessary layers of program oversight and contract reporting, restructured our test program and streamlined the production schedules," Colonel Mike Guetlein, production program manager, said in a statement.

The contract comes on top of advanced procurement funding awarded to Lockheed in 2012 and 2013 to start buying parts that take a long time to order. It will also fund completion of the associated ground operations and processing updates.

SBIRS is a new U.S. strategic missile warning system that replaced the 1970s Defense Support Program satellites. It provides continuous early warning of ballistic missile launches and other infrared surveillance to U.S. leaders.

It includes a mix of satellites in geostationary (GEO) orbit, sensors on other satellites in highly elliptical orbit, and ground hardware and software. The first two GEO satellites started operations in 2013. The third GEO satellite is in testing and the fourth is in final assembly, Lockheed said.

By Andrea Shalal

WASHINGTON (Reuters) - The U.S. missile defense system managed by Boeing Co on Sunday hit a simulated enemy missile over the Pacific in the first successful intercept test of the program since 2008, the U.S. Defense Department said.

The intercept will help validate the troubled Boeing-run Ground-based Midcourse Defense (GMD) system which provides the sole U.S. defense against long-range ballistic missiles, and the Raytheon Co kill vehicle that separates from the rocket and hits an incoming warhead.

"This is a very important step in our continuing efforts to improve and increase the reliability of our homeland ballistic missile defense system," said Missile Defense Agency (MDA)Director Vice Admiral James Syring.

He said the agency would continue its ongoing drive to ensure that the ground-based interceptors and overall homeland defense system were effective and dependable.

Reuters reported on Friday that the Pentagon is restructuring its $3.48 billion contract with Boeing for management of the missile defense system to put more emphasis on maintenance and reliability.

Sunday's high-stakes test came after the system had failed to hit a dummy missile in five of eight previous tests since the Bush administration rushed to deploy the system in 2004 to counter growing threats by North Korea.

Earlier this month, Syring said that another test failure would have forced the Pentagon to reassess its plans to add 14 more interceptors to the 30 already in silos in the ground in Alaska and California.

During the test, a ground-based interceptor launched from Vandenberg Air Force Base, California, hit a target built by Lockheed Martin Corp that was launched from the U.S. Army's Reagan Test Site on Kwajalein Atoll in the Republic of the Marshall Islands, according to the Pentagon and Lockheed.

Lockheed said the unarmed 45-foot (14-meter) target was configured to closely mirror the capabilities of ground-launched missiles that can travel 3,000 km to 5,000 km (1,800 to 3,400 miles).

All components involved in the test appeared to have performed as designed, the Pentagon said. Program officials will spend the next several months assessing the performance of the system using telemetry and other data obtained during the test.

The test marked the first successful intercept by Raytheon's Exoatmospheric Kill Vehicle Capability Enhancement II, or EKV CE-II, which failed in both previous tests conducted in 2010.

Jim Chilton, vice president of Boeing Strategic Missile & Defense Systems, demonstrated the system’s performance under "an expanded set of conditions that reflect real-world operational requirements." Boeing said the operational complexity of the GMD system was "a major engineering challenge."

Raytheon underscored the importance of testing and said Sunday's successful intercept kept the United States on target to increase its interceptor inventory to 44 from 30 by 2017.

Northrop Grumman Corp integrated data from U.S. missile warning satellites and sea-based radars to help identify, track and destroy the target.

Ten of the interceptors now in place carry the kill vehicle used in Sunday's test. The other 20 carry an earlier kill vehicle that failed in a July 2013 test. Syring has said a fix will be implemented for that issue by year's end.

Riki Ellison, founder of the nonprofit Missile Defense Advocacy Alliance, hailed the successful test as a big step forward for the troubled program, and said it would allow U.S. military commanders to reduce the number of interceptors that would be fired at an incoming ballistic missile.

"This success is a significant milestone ... that demonstrates the system's reliability and increases the confidence of the North American Combatant Commander ... responsible for the defense of the country," he said.

Critics said the Raytheon kill vehicle had still only succeeded in one of three tries, and urged Congress to rethink plans to buy 14 more of the flawed interceptors at a cost of $75 million each, or just over $1 billion.

"Would you spend $1 billion on an insurance policy that only worked one third of the time?" said Tom Collina, research director at the Arms Control Association. "We need to put the money into making the system better, not bigger."

Phil Coyle, former Pentagon chief tester and a longtime critic, called for accelerated work on a new design. "We need to make sure we have a system that works, not expand a system we know to be deeply flawed," he said in a statement.

據新浪軍事報導:美國國防部官員稱,中國軍方上周進行了新型高超音速飛行器的首次試飛,高超音速飛行器的目的是突破美國導彈防禦,向美投射導彈彈頭。

不願意透露姓名的官員稱,這種新型高超音速滑翔飛行器的實驗是在1月9日進 行的。五角大樓已將中國的這一實驗性武器取名為WU-14。

高超音速飛行器是中國神秘的戰略核力量及常規軍事和導彈專案向前邁出的重要一步。

就中方實驗進行討論的官員們稱,美國 探測到中國新型高超音速飛行器在中國 上空的飛行測試時以非常高的速度飛行 。官員們稱,高超音速飛行器看起來是 被設計安裝在中國洲際彈道導彈之上, 隨後在近太空以10倍音速滑翔和機動,飛向目標。

國防部的一位發言人證實了中方實驗, 但拒絕提供細節。國防部發言人、美國海軍陸戰隊中校傑佛瑞-普爾對《華盛頓自由燈塔》稱:「我們對外國防務活動 進行了例行的監控,我們獲悉了此次實驗的情況。不過,我們不會就我們所獲 得的外國武器系統的情報或者評估發表 評論。我們鼓勵中國就其防務投資和目標採取更透明立場,以避免誤判。」

美國、俄羅斯、中國都參加了高超音速武器競賽。它們都在研發高速航太飛行器。印度也在研發其布拉莫斯巡航導彈 的高超音速版。
