This is propaganda, it serves its purpose, it cannot and shouldn't go deep, otherwise not many people can get it.Two carriers on the same screen aren't necessarily that important.
Having two carriers on screen with a decent airwing shown, accompanied by an extensive and capable escort fleet, and both carriers having each embarked on multiple years of workup and multiple open Pacific exercises prior to this, OTOH makes this dual carrier exercise a bit more notable and more potentially useful.
