    That’s the point. Cheyenne is basically the ONLY super hard target in the USA, apart from individual ICBM silos. Those 20mT warheads might work against the former, but are worthless against the latter on a large scale.

    I’m not sure it’s actually ended.

    Yak-130 is MITTEN. No name for J-10 or Ka-52.

    The last names assigned were either to a missile or an aircraft, I forget which. The Su-47, MiG 1.44, MiG-AT, and Yak-130 all got names (FIRKIN, FLATPACK, MISER, MITTEN), and I know a few of the newer SS-N-whatevers did too. I can’t remember those off the top of my head.

    Wasn’t somebody supposed to get their Mirage F.1s upgraded with MICA?

    Also, do consider that not all F.1s lack BVR capability, some of them can fire the Super 530. Granted, it’s SARH and that puts you at a disadvantage against somebody with an ARH BVR weapon, but it is a capability that exists. Up against a non-BVR FISHBED, an F.1 would stand a good chance of swatting it down with a Super 530 at BVR range. Closer in it’d depend on the pilots of each aircraft. The MiG-21 did prove to be capable in that regard against comparable Western fighters like the F-4 over Vietnam, so it wouldn’t necessarily be easy pickings for an F.1.

    Only 30 or so 20mT R-36Ms isn’t a viable hard target force. You can drop one into a missile field in the USA and not damage the majority of the silos in the area because of the rapid decrease in the blast pressure wave as it radiates outward from ground zero. That’s why you need more accurate, smaller warhead weapons, with the emphasis being on accuracy.

    City killers are better as big gigantoid bombs. A 20mT weapon will potentially kill everyone from Washington, DC to New York City, depending on the winds. And, being one bomb, you’ll do it with less fallout, meaning you’ll have a lesser chance of hurting yourself in the process during the rebuilding stage after the war. Those 30 or so R-36Ms with the big warheads could theoretically wipe out the entire US population. You don’t necessarily use a gigantic warhead because it’ll carve out a bigger piece of real estate, mind you. Blast effects are roughly half of the total energy output of a nuclear detonation. The other half is the real killer.

    While an 800kT warhead is more powerful than a 550kT warhead, it’s not that big of a deal in the grand scheme of things. The 20 megaton warhead isn’t going to be your bunker buster, either. It’ll be a field killer, given that there are small numbers in service, or alternatively a city killer. The silo/bunker killers will be the most accurate weapons typically. Back in the 60s and 70s you would have used a bigger warhead for a silo/bunker killer to get over accuracy issues, but nowadays you don’t need such a warhead for that purpose. Significant accuracy increases mean that you can put a much smaller warhead close enough to a hardened silo or bunker to get a kill.

    pilots will want to stay off any emissions, unless they have some good counter to incoming missiles.

    That right there is where HOJ comes in. When you start jamming to counter the missile, the missile’s HOJ feature tracks on the source of the jamming. It’s a form of Electronic Counter-counter Measures (ECCM) designed to defeat certain types of airborne ECM. It’s not a seeker, it has nothing to do with the seeker assembly, it’s a form of ECCM logic in the guidance software. IR missiles have ECCM in the form of flare rejection capability in some cases, radar missiles have HOJ as a form of ECCM.

    What difference would it make to a seeker what signals it is homing at, provided the signals frequency emitted is in the seekers repertoire ?
    I believe the difference must be academic.

    It’s far more than an academic difference. HOJ characteristics are part of the ECCM logic of the guidance system, they are not related to the seeker of the missile per se. What you were describing was a passive homing head like what is used on the Russian R-27P. You don’t design a HOJ seeker, you design, for instance, an ARH seeker with HOJ logic. That way, when radar jamming is encountered, the HOJ logic kicks in and tells the guidance system to point ths missile towards the source of the jamming.

    What’s stopping the other guys receiver from reacting to the photons, at half the distance, since your photons have to travel all the way back and scatter while doing it.
    After your photons has bounced they also have given away some energy to the other guys airframe.

    The point is that an LPI radar is designed to operate in such a manner that the other guy’s receiver won’t detect it at a tactically useful range.

    If you want a seriously technical look at how LPI works, check this out:

    It doesn’t focus so much on stealth aircraft design like the title might suggest, but rather LPI radar design and how it works in a tactical environment. I’ve got a copy and this is probably the best reference you’ll find dealing with the topic of LPI radar.

    That’s if the other guy are using radar and you are not, and is actually my point, its the guy with radar ON that are seen first.

    Not necessarily. If you have a basic radar and I have an LPI set, my RWR is going to get a hit first. That’s the whole point behind LPI radar.
