    What’s to prevent the two programs from being merged and producing separate USAF and USN variants?

    Have you ever thought of the consequences of what would happen if the US intervenes and is unsuccessful? US planners would have or they are not doing their jobs properly.

    Well, there’s also the probability that the US intervenses and is successful. Would love to take a peek at the war plans for Taiwan’s defense and all its iterations. Right now its advantage US by a wide margin IMO.. China will try to close the gap, the US will try and maintain or even increase it leveraging its technology.

    It will take some fancy flying for a weapon to navigate a cave or tunnel.. this will be interesting.

    Isnt the U.S. bound by LAW to defend Taiwan? Any administration would have to defend or face impeachment! So hoping the U.S. wont come to Taiwans aid is a mistake. Also the geopolitical rafications of a Chinese land grab with no response would be BAD for the region.

    There was a US – ROC Mutual Defense Treaty but the US cancelled it when it made the political decision to recognize the PROC. It was replaced with the Treaty of Taiwan which commits the US to provide defensive arms to Taiwan and provide some assurance of American ability to support Taiwan in case of hostilities. Its not as ironclad a commitment as the Mutual Defense Treaty had been and doesn’t explicitly committhe US to use force in defense of Taiwan. Something for the lawyers to resolve while Taiwan is being pounded by missiles from the mainland.

    My personal opinion is that the US cannot afford NOT to aggressively defend Taiwan against a PROC attack. Not to do so would be seen as conceding half of the Pacific to the PROC and the US would be a superpower status would morph into that of a paper tiger.

    My thoughts too.. its light years ahead of the RAM treatments we saw with the B-2 for instance.

    Here’s something interesting from AvWeek..

    http://www.aviationweek.com/aw/generic/story_channel.jsp?channel=defense&id=news/asd/2010/05/17/10.xml&headline=New%20Stealth%20Concept%20Could%20Affect%20JSF%20Cost

    New Stealth Concept Could Affect JSF Cost

    May 17, 2010
    By Amy Butler

    FORT WORTH — As the debate rages about Joint Strike Fighter life-cycle cost, Lockheed Martin officials are raising a previously unheard point to bolster their low-price claims — a new low-observability (LO) substance called fiber mat.

    Lockheed officials avoided the need to use stealthy appliqués and coatings by curing the substance into the composite skin of the aircraft, according to Tom Burbage, executive vice president of F-35 program integration for the company. It “makes this airplane extremely rugged. You literally have to damage the airplane to reduce the signature,” he said in an interview with AVIATION WEEK. This top-fiber mat surface takes the place of metallic paint that was used on earlier stealthy aircraft designs.

    The composite skin of the F-35 actually contains this layer of fiber mat, and it can help carry structural loads in the aircraft, Burbage adds. The F-35 is about 42% composite by weight, Burbage says, compared to the F-22 at 22% and the F-16 at 2%.

    Lockheed Martin declined to provide further details on fiber mat because they are classified. But the disclosure of this new substance comes at a time when Lockheed Martin officials are arguing that maintenance costs for the F-35 will be lower than anticipated by operators.

    Officials at the Pentagon are required to complete their life-cycle cost estimates for the Joint Strike Fighter by the end of the month to certify that the $328-billion program can move forward despite a major cost spike. However, this has been an issue of controversy. A U.S. Naval Air Systems Command study recently stated that 65 years of sustainment for the single-engine stealthy fighter could cost about $442 billion (in Fiscal 2002 dollars) more than planned.

    U.S. Air Force Chief of Staff Gen. Norton Schwartz said in an interview this week with AVIATION WEEK that he feels maintenance numbers for the conventional takeoff and landing version are “manageable,” but he did not provide a number. A sustainment cost for all three variants is needed to proceed with Nunn-McCurdy certification after the 57% cost overrun.

    Amid this debate, Lockheed Martin continues to claim that sustainment costs for F-35 will actually be lower than its predecessors. But the company’s argument faces the same challenge as its assertion that the Pentagon Cost Analysis and Program Evaluation (CAPE) office’s development and production estimates are inflated. Fundamentally, company officials say, Pentagon estimates on both points rely too much on data from legacy aircraft.

    Schwartz, who represents the service that will eventually operate the preponderance of the Pentagon’s F-35 fleet, appears unsympathetic to Lockheed’s complaints about the estimates. “This is a show-me situation for the government, the program office and the contractor,” he says. “Notwithstanding what they think of the estimate, that is what we budgeted to. If they want to sell more airplanes, there is a clear path ahead.”

    One wonders what the Russians see as the role for this proposed helicopter. If its an attack helicopter, tyhen it had better be heavily armored like a Hind or an Apache to have any chance of surviving low and slow where it will operate. It is still to be proven if stealth and noise reductions will be possible to any significant degree but the thing will still be visible to the naked eye and will generate a heat signature making it vulnerable to small arms fire and all sorts of air defense systems.
    If recon is its mission, a UAV could get the job done more cheaply and without endangering a a crew.
    As for battling fighter jets. this is a job best left to the PAK-FA:D

    Would Japan readily allow US forces to operate from bases in its territory in any war with China? Or can the US do so without permission?

    Saddam had limited choices. The other alternatives:
    A. Send them up to be slaughtered.
    B. Keep them grounded to be slaughtered.
    C. Bury them in the desert.

    News just in that the USN will purchase an additional 124 SH jets after Boeing extended a 10% discount. No doubt such aggressive pricing would make India sit up and take notice. Will Boeing offer simil pricing to India?

    What will the Russians have to offer to the low to mid-range market requirement? Expect the Chinese to gobble up a lot of orders.

    F-35C > F-35A

    Its also significantly more expensive.

    Didn’t a Tomcat fall off a carrier deck a long time ago and the USN had to mount a major salvage operation to keep its Phoenix missile system out of SOviet hands?

    None of that post was talking specifically about AMRAAM. There was hypothetical talk about what AMRAAM could do if it has navigation.

    It was talking about missiles, and their historical methods.

    People on here like to throw out things like data link and mid-course updates, without any consideration for what they might actually be. Is it a vector relative to the missiles current orientation? Is it 2 3d points in space and the missile does the calculations for intercept?

    To provide info without using the missile seeker head, you need 3 pieces of data, the target location, the missile location and the missile orientation.

    To reduce that to a relative vector the guiding aircraft needs to know where the missile is mid course. Now, unless the missile is emitting and can be picked up with RWR, then the launch/guide aircraft needs to use its radar.

    With navigation, it can be done passively. Without, it cannot.

    That’sthe advantage of a missile having an INS with GPS strapped on and with 2-way datalinks.
