    Since that phased array can shift beam in milliseconds without entire antenna turning.

    Since that phased array can shift beam in milliseconds without entire antenna turning.
    Can it that really? No!
    What is with the signal propagation delay?
    The spot moved than halted (Transmitting –>Duration–>Receiving–>Processing) than moved than halted(Transmitting –>Duration–>Receiving–>Processing)…
    A full scan need some 1/10s for EScan, depending on the distance and puls retention frequency!

    We remind us here in Europe very good on the Lockheed scandal. ๐Ÿ˜‰

    How many years is now the F-35A already too late?
    Two years and still no serial prototype is flown!
    The current F-35A-Pre-Pre-serial-prototype is only a temporary solution.
    With an engine that have a serious design error. (Cracks in the compressor blades). The F-35A can not even drop a bomb without a near crash. The same error also occurred on the F-22. ๐Ÿ˜‰

    Each Radar with SAR-mode and a real Doppler detector (old Doppler Phasedetectors misinterpret the F-117 and B2 as a fixed target) can detect a Stealth target.

    plasma can exist in temparatures below 0 degrees C,and it doesnt have to glow [in visible light],its the fiziks thats problem it has to be thick as a wavelenght that means possible centimeter,decimetar thick sheets of plasma screens.

    Glowing is independ from temperatur.
    Know you what the Aurora Borealis is?
    Right, glowing Plasma in the subzero temperature zone.
    Glowing is temperatur independ and when this glowing is invisble UV then is this much better! Also, it takes some time for plasma to be re-absorbed by the atmosphere and a trail of ionized air would be created behind the moving aircraft. The same UV detectors there is used for Rocket detection can detect this Trail and your invisible glowing SU-35-1 is seconds later dead!

    Somtimes is plasma reflectiv (ionosphere or Plasma Antennas).
    The plasma itself emits EM radiation.
    When your plasma is on then is your Radar useless and you are blind.
    Plasma produce heat.
    The Langmuir frequency —> the plasma is transparent and interact not with the Radar waves. Control of plasma properties is likely to be important for a functioning plasma stealth device, and it may be necessary to dynamically adjust the plasma density, temperature or composition, or the magnetic field, in order to effectively defeat different types of radar systems. Radars which can flexibly change their transmission frequency might be less susceptible to defeat by plasma stealth technology. A plasma might also be used to modify the reflected waves to confuse the opponentโ€™s radar system: for example, phase shifting the reflected radiation would frustrate some old Doppler filter and might make the reflected radiation more difficult to distinguish from noise.
    A real Doppler filter will not affected.
    Plasma emit a glow, this is not necessarily compatible with overall low observability.

    Like LO geometry and RAM materials, plasma stealth technology is probably not a panacea against radar.

    But plasma antennas could be an alternative to AESA.
    They can be electrically (magnetical) steerd without delay and switch on and off on demand.

    About RCS,

    As I said RCS reduction is always welcome because a contact is very different from a stable lock. With a lock you can know the speed, altitude and direction enabling to give the info for the missile. But to have a lock you need to have the time that your processor calculates all those data. If the contact is not stable there is no chance to have this very useful information. If you add to RCS reduction EW then it may be even harder to have/keep stable lock. So RCS reduction combine with EW is a very worthy solution to increase survivability.

    Has your sailboat a Mono-Puls-Radar? Sure not and this make the difference.

    Where on this chart is a Super Hornet, Rafale, and Typhoon when loaded with weapons?

    :dev2: :diablo: ๐Ÿ˜€

    Where is the F-35 flying? Which land use the F-35 in service now? The F-35 is currently the most expensive hangar Queen! This nonflying Preserie Prototyp F-35 is not compliant with the Serial Standard F-35. SU-35-1 and F-35 is not avaible yet. :dev2: :diablo: ๐Ÿ˜€

    I cannot wait for your explanation about how lower wing negatively affects RCS..

    Lower WING SWEP and Lower Canard swep! Not lower wing! And I forget the Rafale Tail has the smaller swep.

    Ever heard of TACIT BLUE? It had straight wings and all-around LO… And of course the B-2A also has a much smaller sweep angle, so it must be a bigger RCS target than the EF-2000, right?

    :rolleyes:

    So TACIT BLUE has straigt wings? Realy not! :rolleyes:
    Tacit Blue has a wing swepe and use CONONTINOUS CURVATURE. ๐Ÿ˜‰
    The B2 has also CONONTINOUS CURVATURE to, no Vertical Stabilizer and much RAM. rolleyes: The B2 need a air-conditioned hangar or rain damaged it’s RAM.;)

    And this myth with the greater Typhoon tail. :diablo:

    Why sawtooth by the Rafale, no swept gaps on the flaperons! I see a lower wing and canard swep, that all not really good for a low RCS!:diablo:

    Who win the contest the F-35 or the F-32?
    The F-32 can only hover at sealevel and arcieve supersonic only after manipulation on the intake. The F-32 was not able to start vertical and arcieve supersonic. ๐Ÿ˜‰ Boeeing construct the X-32 with baffels.
    When you insert baffel in a existing intake than choke you the airstream. You reduce the cross-sectional area. And Ups only the transonic area rule must we consider.

    And why has this Rafale M no Sawtooth?

    F-35 JSF Hit by Serious Design Problems

    F-35 JSF Hit by Serious Design Problems (updated)
    by Johan Boeder in The Netherlands. Earlier versions of this article have been published in the Dutch press and Defense-Aerospace. DID has worked with the author to create an edited, updated version with full documentation of sources.

    On May 3, 2007, during the 19th test flight of the prototype of the F-35A Joint Strike Fighter (JSF), a serious electrical malfunction occurred in the control of the plane. After an emergency landing the malfunction could be identified as a crucial problem, and it became clear that redesign of critical electronic components was necessary. Producer Lockheed Martin and program officials first announced there was a minor problem, and later on they avoided any further publicity about the problems.

    The delay has become serious, however, and rising costs for the JSF program seem to be certain. In Holland, Parliament started a discussion again last week. Understanding the background behind these delays, and the pressures on European governments, is important to any realistic assessment of the F-35’s European strategy โ€“ and of the procurement plans in many European defense ministriesโ€ฆ….
