    sorry actually i mean DEAD not SEAD 😮 confused these 2

    Since when did the 9x become a SEAD weapon?

    well in theory anything you can fire at ground target could be SEAD weapon , from GBU-12 to AGM-88 , and since Aim-9X have new air to ground ode i think it could be effective ( faster than HARM , can carry more aim-9 , lower RCS , smaller probably harder to intercept by gun

    PAK-FA could also be great at SEAD , DEAD if it can carry Hermes missile , that things seem very potent
    range = 100 km
    speed = 1300 m/s ( about mach 3.6 )

    so it both much faster and can carry more per weapon station compared to SDB or SPEAR , disadvantage is that it not fire and forget

    Brimstone block II also seem pretty decent
    range = 60 km
    speed = 450m/s ( about mach 1.25 )

    so a bit shorter range than SPEAR , carry less per weapon station but a bit faster

    Aim-9X block III
    range = 55 km
    speed = 900 m/s ( about mach 2.5 )

    shortest range but probably the fastest SEAD weapon in the West

    According to its flight manual, F-106 is limited to M2.0 from 35k feet to 50k feet. Its max ceiling is 55k feet. With 2×360 gals, F-106 has max speed of M1.9 at around 38000 lbs.

    In short there is really nothing to compare. Its performance its comperable at best to F-4, F-15 etc. Both MiG-31 and MiG-25 can go M2.83 with their full AAM payload. MiG-25RB can go M2,7+ even with 4xFAB-500M-62 bombs hanging from its pylons.

    i think what people are trying to say is that F-106 have really long supersonic range , probably better than mig-31

    If you hold a laser to a camera -all automatic mode- it will simply tighten its diaphragm or increase its shutter speed, and you will clearly see the laser source. Now imagine if such technology is developed, how easily a modern IRST can be developed to counter it.

    your eye does the same thing too , how ever that only have a limit EX : imagine looking at the sun

    You can “jam” a radar because it’s trying to determine your range (and hence range rate) from the return signal. If it can’t read the return because of noise or because there is a fake return with the “wrong” range it’s not much use. An IRST is simply doing detection, azimuth and elevation. Flashing a laser at it just makes you more detectable.

    IRST is basically just an IIR sensor , Flashing a laser at it will blind it with effect same as noise jamming to radar , but i dont think you can do that at long range any way

    why put a 100 kW laser on F-35 when engine has to be taken out to make room for it,
    and the frame hooked up to a nuclear power plant ?

    dont know , really they seem to think it a good idea , but it seem to have really ****ty range ( could be useful to intercept AAM and SAM probably )
    i prefer EM weapon or hyper sonic weapon anyway

    F-102 and f-106 look so similar , do they perform very different or the same

    Think you need to re-read the request- he was looking for realistic….

    While all of those could do the job, none are sitting at Edwards ready to go, not even in semi-plausable fiction.

    only need to modify the B-1B engine alittle bit to revert it back to B-1A , i think

    I never saw such a low-drag design before or after,
    it has got to out-range just about anything in supersonic flight short of intercontinental supersonic bombers

    it look kind of the same as f-102 , mirage 2000 and migare IV

    F-106 had some issues, the biggest being pretty limited in its role. I personally thought the airframe was pretty robust and made sense. But four micro AAMs for armament was pretty restrictive. Imagine the range F-35 would have had with a payload requirement of 1500 pounds…total.

    http://modelingmadness.com/review/viet/us/dix106m.jpg

    In reality it had been five AAM, until around the early 70’s when they replaced the center nuke with a cannon.

    to be fair it carry more missiles than F-35 ,even have a nuke missiles , and despite being micro the range of 9 km is not very short by it’s time
    missiles actually seem quite big

    To give you an idea of what had to be sacrificed to make the Spear3:
    The SDB2 has a 50-ish lb warhead
    The Spear3 has an 18lb warhead.

    where did you get the warhead weight of SPEAR III ?
    btw they seem to have a little bit different design

    SDB II have wider wing span + 4 tail fin ( not sure what are the advantages , disadvantage though

    The F-35 won’t have a DIRCM before several years ( block 4 or 5 ).

    I am not talking about damaging of destroying the enemy IRST, just jam it, so it wouldn’t take that much power. It would be a great advantage, the F-35 could continue to use its afterburner without risk of being detected and targetted. The APG-81 could even jam the enemy’s radar at the same time while the F-35 is guiding its missiles.

    My question was general, but concerning the F-35, it will have secret features, I am wondering what they could be.

    i think it still require a decent amount of power , btw they gonna put a 100 kw laser on F-35 in future so may be that could work , but anyway the targeted range by IRST limited to about 40 km with best IRST nowaday ( OLS-35 on su-35 can only do that at 20 km ) so that not really a big threat not to mention without information about speed, heading or aspect angle of target the missiles arenot going to have very high PK

    MALD and MALD-J

    can MALD be carry on the AA station , it seem pretty small

    The answer to suppression of air defense is spelled UAV

    [ATTACH=CONFIG]231169[/ATTACH]

    UAV could be shot down too , i think the answer to swam of loitering weapon , probably a MALD with a warhead , that thing fly really far though ,about 920 km or close to that

    SDBII is the start and the emphasis no doubt is on affordability given that they requirement would likely be for a very large purchase over the years. How hard would it be for Raytheon to add the TJ-150 to the SDBII for a future iteration of the munition? The advantage raytheon will have going forward with the SDB2 is that there would be a customer base already for the weapon and the economies of scale would kick in, where they go from there obviously depends upon the market study and what they think will sell.

    there no place left to add fuel and engine , intake in the GBU-53 , unless it be redesigned from the start to match the SPEAR III
