I should think that the F-35 may in future (when it works in service) have some good receive (ESM) capability. However, what use it makes of it will depend on automation and be limited by the frequency and aspect coverage of whatever active devices it may have.
But Amos has to sell this capability, because eventually you have to ask: where is it that I need a stealthy, supersonic aircraft, but I don't need EA and AEW?
Moreover, developing a stealth-compatible escort-jammer pod won't be cheap, but I suppose the Marines will, as usual, thcream and thcream and thcream until the Navy is told to fund it.
