“International Herald Tribune,” freelance writer Liu Guowei from Beijing October 26, the U.S. Missile Defense Agency will be a $ 1 billion contract was awarded to Lockheed Martin to upgrade the U.S. ” Aegis “missile defense system performance. Reuters reports: “China’s rapid development of ballistic missiles, making the task of the rapid escalation of the U.S. Navy has become more urgent.”
engage in two-pronged approach to upgrade
Lockheed Martin is the “Aegis” missile defense system prime contractor, in recent years has not only been a lot of “Aegis” system of production contracts, and swept the “Aegis” system upgrade follow-up business. In the Reuters report, Lockheed Martin’s sea-based missile defense project leader Orlando Carvalho said: “The new contract will make ‘Aegis’ ballistic missile defense system to effectively address global security threats spiral trend will further increase with the number of ballistic missile defense capability of the ship. “
then the U.S. military hopes to” Aegis “system to do what the upgrade? In recent years, Lockheed Martin from the “Aegis” system focused on continuous upgrading of technology, the U.S. will focus on two aspects of efforts to raise the “Aegis” system of missile defense capability. One is using the new radar signal and data processor, improved shipboard SPY-1 radar to track, identify true and false target ballistic missile capability, so have limited ability to intercept long-range ballistic missiles, to improve the “Aegis” system to deal with New ballistic missiles kill probability. The second is to improve the interceptor missile, increasing the blocking battle space, this has been in the military and the “standard (SM)” prime contractor Raytheon missile cooperation, “SM-3″ of the interceptor missile upgrade.
many successful interception test
“Aegis” is a U.S. Navy ship-based ballistic missile defense system, “Aegis” weapons control system and the “standard “air defense missile, based on improved and developed as a mobile sea-based ballistic missile defense system. The first set of “Aegis” system with the “Ticonderoga” class cruisers enter the U.S. Navy in 1983 and since, the world’s total of 21 “Aegis” warships equipped with anti-ballistic missile capability, the U.S. Navy 19, Japan Maritime Self Defense Force 2.
2006 In May, the U.S. Navy, “Lake Erie” cruiser was in the last paragraph of a short-range ballistic missile’s flight was successfully intercepted. June 2008, the Pacific Missile Range in a test, “Aegis’ Ballistic Missile Defense Weapon System (BMD) once again successfully detect, track and intercept a short-range ballistic missile target. As of last year, “Aegis” BMD system is still middle-guided phase successfully completed 12 interceptor missiles outside the atmosphere.
addition to test anti-missile capability, “Lake Erie” cruiser “Aegis” BMD system was also temporary transformation, in February 2008 successfully destroyed a satellite out of control, demonstrating the ability of powerful anti-satellite system.
worried about China’s missile
“Aegis” anti-missile system after several years of testing anti-missile capabilities performed well. But the U.S. still spare no revision upgrade, the upgrade contract signed when it is stressed that the “response to the rapid development of China’s mobile ballistic missile warhead threat”, in fact, primarily out of fear that Chinese ballistic missile to its aircraft carrier the threat of large surface ships.
10 January, the PLA’s National Day military parade showcasing several new types of missiles, they immediately became the U.S. military “target.” October 6, former U.S. Assistant Secretary of Defense Peter Brooks in “The New York Post” to “Why is the U.S. worried about China,” the title, saying “China’s DF-21 missile is the first one capable of moving targets at sea to combat the ballistic missile which can occur in the United States when the war was used to attack U.S. aircraft carriers China, configure the mobile missile warheads on a range of more than 1,600 kilometers … … In addition to their destruction before launch, the U.S. Navy without a high degree of confidence to deal with the DF-21 missile. “
However, with these highly played up” China threat of ballistic missiles, “the report compared to many technical articles at home and abroad also calmly pointed out that in the vast ocean to detect and lock on a moving target, such as aircraft carriers and other large ships, is still a very challenging problem. Because large-scale ballistic missile attack is mainly used for fixed targets, pre-determined coordinate system to calculate its missile trajectory, the missile was launched along the intended trajectory to the target, and attack large moving targets beyond its director. Military analysts believe that the U.S. invest heavily on the “Aegis” anti-missile system to upgrade, is to strengthen the technological advantages ensure that its naval fleet in the vast ocean of absolute security.
