You can argue the "patrol around for 6 hours till you find it and then make another sortie to where it is and attempt to sink it" argument all you want, but the "Wins ter warsz!" dweebs will always have the ability to be one step ahead of you.
I found a boat up near the one in the origional picture, used Arados to make a quick flight up there, and was promtly intercepted by a 262 about 50 miles from the enemy CV. Tried NOE B-17's, high alt stukas, and I was intercepted by the same guy each and every time.
They don't have a CAP over their carrier, and radar distinguishes between friendly and enemy contacts. If they're watching the CV, you have absolutly 0 chance of supprising them.
CV hiding is getting ridiculous, and on top of that, why should you get to permenatly keep a carrier that you COULD NOT supply in real life. IRL, you would have to replace the engines, the guns, everything, to be able to use YOUR ammunition, and YOUR spare parts.
