    Dude, the MKI alone generates far more power than the Mi-8 and the PAK FA doubles that.

    You got a WSO in the Rafale. It's plenty.

    Regardless the PCA will match that.
    “PCA will focus on maximizing tradeoffs between range, payload, survivability, lethality, affordability, and supportability.

    That in itself doesn't mean anything. Rafale's radar could be twice that at 10KW, Typhoon's radar could deliver as much as 15KW. The F-22's could already be more than 15KW. The PAK FA, who knows, it could be well over 50.

    Jamming systems are not very powerful. Even something as big as the NGJ wouldn't deliver more than 5KW in total. The first version of ALQ-99 delivered 11KW, the newest ones deliver 6.8KW. So jamming power is actually decreasing.

    And Spectra is a smart jammer, it's not an obsolete noise jammer that no longer works. Very few modules will be used for jamming. The radar is also a very limited jammer, in capable of 360 degree jamming.

    “I’ve gotten into a little hot water with my fighter pilot brethren over this, because I say things like, ‘Hey, it may not necessarily be a fighter,’” he said, adding that the aircraft will likely still receive the “F” designation reserved for fighter jets. “A typical fighter pilot for air superiority would say you need 9Gs, two tails, a gun, short range. That’s what fighters are. This is something that’s a little bit different and has some different attributes in my mind.”

    ...but it will also need to be able to operate at greater distances than current platforms, he said.

    The PCA will have a very long range, that's obvious. Otoh, PAK FA has only 4000Km on internal fuel.

    Longer than existing fighters but not 6,000 miles.

    PAK FA has a 35% fuel fraction (22,700/64,530), it will therefore struggle to match the 3,600km range of the Su-35 (39% fraction).

    F-22's is 20kW.

    https://en.wikipedia.org/wiki/AN/APG-77

    Don't forget about cooling. GaN will add power but the same would be true for Richtag AV. Don't forget radar is 2-way (1/R^4), jamming is one way (1/R^2) so 100kW is serious juice.

    I've just shown you a video showing that Richtag AV has 100kW.

    Noise jamming does still work even against AI. Want to prove this? Go stand next to a 140dB speaker and see if you can hear anything else.

    Swash-plate enable 220deg coverage for Radar 2. So you would never have to change bearing more than 70deg to jam a source.

    But the engines are very efficient. The 117 is 25% more efficient than the AL-31F and the Type 30 will be more than 15% efficient than the 117.

    Range is also dependent on drag/lift and engine efficiency.

    And PAK FA's fuel fraction is unknown. It is smaller and lighter than the Su-35 and there is a chance it carries more fuel.

    Effective radiated power is total power of the EW, not just one side. It's a 360 degree system. And you need large power for area jamming, aircraft don't need that for self protection.

    The ear can't tune out sounds on its own.

    Still way more than usual a/c jamming.

    No system can cope with complete overload.

    Allegedly. Believe it when I see it. 25%? Not without variable cycle.

    22,700lbs. It's known.

    It is variable cycle.

    Google Type 30 PAK FA and variable cycle engine. You will get all the evidence you need.
