    Mình cũng không nghĩ rằng vũ khí của F-35 rất hạn chế mặc dù có phương án lắp cho F-35 vũ khí laser.F-35 với chế độ đánh tàng hình chỉ có hai khoang vũ khí ở hai bên . mỗi khoang theo cơ số chuẩn là một tên lửa không đối không và một bom, như vậy có m2 tên lửa AA và hai bom AG nếu chỉ đối không thôi thì có thể thay bom bằng tên lửa AA, như vậy là chỉ có 4 tên lửa AA ( giống như anh Shukhoi lúc đầu cũng chỉ muốn là có 4 tên lửa).Khi bắn thì cánh cửa khoang vũ khí mở ra và giá treo tên lửa được đẩy ra ngoài và tên lửa được phóng đi còn bom thì rơi tự do xuống sau thì điều chỉnh theo cơ chế của từng loại bom.Có lẽ sau khi bắn hết tên lửa thì F-35 sẽ tăng tốc bay mất nhỉ ? Còn lại cũng như F-22 F-35 có thể đeo ở ngoài khoang vũ khí khá nhiều loại vũ khí nhưng chức năng tàng hình sẽ giảm rõ rệt.Các bạn có thể bàn xem RCS của F-35 ở mức độ nào ?

    Như vậy là F-35 có khả năng đeo vũ khí trong khoang kém hơn F-22 và T-50 vì F-22 có khả năng đeo từ 6-8 tên lửa AA trong chế đôi tàng hình còn T-50 là 10 quả.Có lẽ nước Mỹ sau này thay phaói của F-35 bằng vũ khí lasermaf hãng Boeing đang chế tạo và gần đây có nhờ tới sự giúp đỡ của Nhật Bản (airborne laser )

    Russian aerobatics jets Rissian vityazi (Russian knights) to show their demonstrative performance in the skies over China
    [3 Mar 2006] /RIA Novosti/
    Aces of the pilotage squadron Russian vityazi are going to participate in China''s national holiday Eagle of Victory which is to be held in late March in the town of Janzyatsz, Khehua province.
    This information was obtained by the RIA Novosti news agency from chief of Russian AF press- service Alexander DRobyshevsky.
    During 4 days of the holiday spectators will watch a formation flying of 5 Su-27s including head-on flying on two aircraft, and a single flying by the formation''s commander colonel Igor Tkachenko, explained Drobyshevsky.
    He also added to participate in the holiday festivities the pilots will have to overcome some 11.000 km. The 5 Su-27s accompanied by an Il-76 will depart from a Kubinka airfield in the suburbs of Moscow. To refuel, they will have to make 4 interim stops.
    According to Drobyshevsky, the Russian aerobatics jets will leave for China as part of the Russian AF delegation which is going to participate in the Eagle of Victory festivities between 15 March and 22 March 2006. The delegation will be headed by major general Aitech Bizhev, the deputy AF commander-in- chief in charge of anti-aircraft defense system for the CIS.
    Russian fighters to fly through Chinese rock
    [6 Mar 2006] /Lenta.ru/
    Russian aerobatics Su-27 and Su-30 jet fighters are going to fly through
    **** named Tyanmen in China, AFP reported. The flight is scheduled for 17-18 March. This **** is a kind of huge arch formed by weathering. Its length is 280, and its height 130 m. The **** is only 28 m in width in its narrowest point, and 57 m in its widest place. Su-27 wing span is 14.5 m.
    The attraction will be arranged in the framework of celebration of the Year of Russia in China. The attraction will be chargeable - in order to see the Russian fighters fly through the **** one should require to pay $ 840.
    Local authorities are going to get a huge profit out of the show. They intend to sell not less than 20.000 tickets. Besides, the attraction is expected to draw attention of many tourists which will positively tell on the development of the province''''s travel industry
    No details are reported on which formation is really going to perform in China. The Su-27 fighters Ruskiye Vityazi formation is amongst Russian flying formations. This is not the first time that the Chinese arrange such an attraction. In 1999 a Hungarian pilot, Besenyei Peter, flied through the **** on a single-engine propeller airplane. But no jet fighters have ever flied through the ****.
    In 1999 the show was organized by International aeronautics, the major international body which is engaged in the organization of aviation-related sports.
    Profit gained that time from the attraction accounted for $308 mn including money made by travel firms in subsequent 3 years. To date China has already invested $6.4 mn in the organization of the event, including insurance amount of $300.000.

    Bác tuat đúng là lơ mơ nhưng cứ hay nói chữ.
    Tức là bác nói CPU Mỹ nhanh vì đa luồng còn CPU Nga ưu việt ở đơn luồng phải không ?
    Elbrus chỉ phát triển trên giấy và các folder là chính thôi. Chỉ được cái dọa thiên hạ mà chưa thấy cái gì cụ thể cả. Kế tục truyền thống quảng cáo của MIG-25 và MIG-29. Đến bọn Transmetta hồi trước ầm ỹ thế mà cuối cùng cũng èo uột đã nên cơm cháo gì đâu.
    Đến đây thì lại hóa ra người Nga giỏi ở công nghệ superscalar, tức là đa luồng chứ không phải đơn luồng à ? Có mỗi một đoạn mà sao bác viết cãi nhau chan chát thế ?
    Nói mãi chuyện này thì thành loãng chủ đề mất. Thôi bác tuat tập trung vào tán nhăng về KTQS thôi, bác chuyển gam sang CNTT thì ngô nghê quá.

    ÚC lo lắng về giá cả và chất lượng F-35 của Mỹ. Uc định mua khoảng 100 F-35 ( đến 2015) để thay máy bay cũ.
    Australia Voices Concerns About Latest Setback to U.S. Stealth Fighter
    By AGENCE FRANCE-PRESSE, SYDNEY
    Australia expressed concern March 14 at news that the new generation U.S. warplane that was to be a cornerstone of Australia?Ts future air force will not have the stealth capabilities initially promised.
    But Defense Minister Brendan Nelson said Canberra still intended to spend up to 15 billion dollars ($11 billion U.S.) on the new warplanes, the biggest military purchase in Australia?Ts history.
    Nelson said he was taking ?overy seriously? news that the U.S. Defense Department had downgraded the stealth capability of the F-35 Joint Strike Fighters (JSF), meaning the planes would be less able to evade radar detection and enemy attack than earlier believed.
    The downgrade, revealed on a Defense Department website and confirmed by Nelson on March 14, lowered the radio frequency signature of the fighter jet from ?oextremely low observable? to ?overy low observable?.
    The setback is only the latest in a string of problems for the $240 billion (U.S.) JSF project, which both Australia and Britain have been counting on to provide their next generation of warplanes.
    Australia, a key U.S. military ally, plans to buy up to 100 of the F-35s from around 2015 to replace its aging fleet of U.S.-made F-111 strike bombers and F/A-18 fighter bombers.
    But some defense analysts have expressed concerns about the performance capabilities and cost of the new planes.
    Peter Goon, a former air force flight test engineer, told The Sydney Morning Herald newspaper the change in the JSF?Ts stealth rating would mean the difference between the warplane appearing as a ?omarble and a beach ball? on enemy radar.
    Nelson said he had met with representatives of both the U.S. Defense Department and the JSF manufacturer, Lockheed Martin, about the latest problem.
    ?We are examining in quite a lot of detail precisely what that might mean, not only for U.S. but indeed for the U.S. and the other partners that are involved in the process of developing and then acquiring the Joint Strike Fighter,? he said.
    ?We have got a lot hinging on this in terms of retirement of our F-111s, the upgrade of our F/A-18s and also in what we do with a variety of our other airframes including the P-3Cs.
    ?We are taking it very seriously but I think at this stage it is certainly not cause for U.S. to abandon the project.?
    Dennis Jensen, a government Member of Parliament and former defense analyst, recently said he did not think the Joint Strike Fighter would be a match for the Russian-built Sukhoi family of strike jets that are or will be operated by air forces in Asia, including China, Indonesia, Malaysia and India.

    Support Systems
    Northrop Grumman will design and produce logistic products for the F-35 Support System. These products include
    establishing and managing reliability, maintainability and supportability requirements that will meet customers?T expectations for
    exceptional flight line performance. Specifically, the company will design and develop all logistic products associated with the
    F-35 center fuselage, to include peculiar mechanical support equipment products associated with weapons loading and the
    United States Navy. In ad***ion, Northrop Grumman is responsible for the development of the F-35 low-observable support
    system which will include producing LO technical repair manuals, LO support equipment (consisting of verification tools and
    portable radars), and LO courseware for all F-35 variants.
    Training Systems
    F-35 training system courseware for individual and group
    instruction will be developed under Northrop Grumman
    leadership ?" internally and by a select, world-class team of
    domestic and international courseware suppliers ?" using
    advanced, emerging development and media
    tools/databases to enable efficient development and
    implementation. F-35 courseware will address all aspects of
    pilot and organizational maintenance training, including
    mission planning system operations and maintainer use of
    the portable maintenance aid. Ad***ionally, Northrop
    Grumman is responsible for F-35 pilot and maintainer cadre
    training development, and course instruction, in support of
    the initial Flight Test Program.
    F-35 Program Overview
    Avionics Development
    Expected to be the largest military aircraft procurement in
    modern times, the stealthy, supersonic F-35 Joint Strike
    Fighter will provide an affordable capability that is superior
    to all current-generation fighter and strike aircraft. It will
    replace a wide range of aging assets for the U.S. Air Force,
    Navy, Marine Corps and allied defense forces worldwide.
    The program?Ts hallmarks affordability,
    supportability, survivability and lethality
    are achieved through modern technology,
    state-of-the-art production facilities, and a
    high degree of commonality among three
    variants: a conventional takeoff/landing
    (CTOL) version;
    a short
    takeoff/vertical
    landing (STOVL) aircraft;
    and a carrier variant (CV). Innovative
    concepts and advanced technologies will
    significantly reduce life-cycle costs while still
    meeting the strike weapon system requirements
    of military customers.
    As a principle member of the Lockheed Martin team,
    Northrop Grumman plays a critical role in the development
    and demonstration of this multi-role fighter, producing more
    than 25 percent of the aircraft. The company?Ts contributions
    span four of its sectors and range from integrating a major
    section of the aircraft''''''''s structure to
    producing key avionics and
    communications subsystems to
    developing mission-planning software
    and training systems.
    Working as an integrated team with our
    customer, teammates, and suppliers,
    Northrop Grumman will
    deliver products
    that help make
    the F-35 the world''''''''s
    most advanced multi-role, stealthy
    combat aircraft.
    The AN/APG-81 fire control radar, with its active
    electronically scanned array (AESA), will provide unmatched
    multi-role capability that supports air-to-air, air-to-surface,
    and electronic warfare missions. This will provide the pilot
    with precision all-weather targeting capability, utilizing
    advanced air-to-ground automatic target cueing.
    In joint efforts with Lockheed Martin Missiles and Fire
    Control, Northrop Grumman is also developing the electrooptical
    distributed aperture system (DAS) and the electrooptical
    targeting system (EOTS).
    The DAS surrounds the aircraft with a protective sphere of
    situational awareness. It warns the pilot of incoming aircraft
    and missile threats and also provides day/night vision, fire
    control capability and precision tracking of wingmen/friendly
    aircraft for tactical maneuvering. The internally mounted
    EOTS provides extended-range detection and precision
    targeting of ground threats plus long-range detection of
    airborne threats.
    Systems Development & Manufacturing
    Northrop Grumman is responsible for the design and manufacturing of the center fuselage, a major section of the aircraft. It
    began the 12-month production process required to complete the center fuselage in May 2004 at the company?Ts state-of-theart
    manufacturing facility in Palmdale, Calif.
    Northrop Grumman''''''''s work on the center fuselage includes integrating all structure and subsystems. The center fuselage
    incorporates advanced technologies and cutting-edge manufacturing techniques.
    The company will complete the first center fuselage in May 2005 and, soon after, deliver to prime contractor Lockheed Martin
    Aeronautics Co., Fort Worth, Texas, for final assembly.
    The F-35 is the first tactical aircraft in history specifically
    designed to be a part of a ?osystem of systems.? The
    mission systems architecture incorporates best-practice
    design to minimize the cost and schedule of future
    capability updates. Northrop Grumman is developing a
    substantial portion of the F-35 mission systems software.
    The company has created a software development station,
    one of the aircraft?Ts key mission systems test stations, that
    enables users to test software on the same hardware
    platforms that will host the software on the aircraft?"
    significantly reducing risk prior to domain and system
    integration.
    Information exchange and situational awareness are
    critical in digital battlespace. Next-generation
    communications systems must be able to costeffectively
    deliver unprecedented amounts of
    tactical information from a myriad of sources to
    F-35 pilots ?" without compromising aircraft
    performance or capability.
    Northrop Grumman is meeting that challenge by
    leveraging our experience with software-defined radio
    (SDR) technology in cutting-edge avionics. Using SDR
    technology, Northrop Grumman will provide more than 35
    critical communication, navigation and identification (CNI)
    functions in a lightweight, compact and powerful
    subsystem. The CNI capabilities include multichannel/
    multiband voice communications, multiple digital
    battlespace connectivity, sophisticated intra-flight data
    exchanges and advanced friend-or-foe identification.
    Northrop Grumman will also design and develop electronic
    warfare equipment in support of BAE SYSTEMS, which is
    developing the aircraft?Ts electronic warfare suite.
    Mission Systems
    CNI
    DAS
    Software Development
    Northrop Grumman will provide software that enables the aircraft to exchange information with other platforms through the
    use of its Interoperable Systems Management and Requirements Transformation (iSMART) process, which is designed to
    assure interoperability. A systems engineering process, iSMART provides the brainpower to ensure the establishment of
    correct requirements. Northrop Grumman is the only company in the world with this capability.
