S!
It is true that it is quite easy to kill a CV or Cruiser with a single fighter bomber with 2 1000lb bombs. I have done it quite a few times, and usually I survive. Personally I prefer a Typhoon because they climb better and have better speed with two bombs, but a Hellcat or Corsair will do too. A P-47 takes too long to get up to 10,000 ft, which is the best height to start your dive.
I know all you guys are complaining about this because it seems unfair that a single plane can screw up 2 hours of moving a CV into position...
Well, learn to live with it.

Historically ships were extremely vulnerable to aircraft attacks. There are literally hundreds of instances which can be pointed to of a few aircraft sinking huge ships.
The real problem is the bozos in the MA who create a course for a TG that parks it on the beach in front of the enemy Airfield, then don`t bother to put up any AIRCAP over the CV. Plus they don`t bother to maneuver the TG when an enemy aircraft appears.
Big surprise when their nice aircraft carrier goes end up and slides into the drink lickity split.
The first responsibility for someone commanding a TG is to make sure they are CAPing it. Jump into a F6f or a Corsair, even a Zeke with some alt. can do the job against a heavily loaded fighter bomber.
I was on the MA the other day, when someone sent a TG right in close. There was no CAP to speak of, just a bunch of aircraft down low furballing off the field which was the target. I got into a F6f and climbed to 10k. (needed to get up quick, otherwise I would have taken a F4UD) Over the next 20 minutes I got 6 or so kills of heavy Corsairs or F6f`s or P-38`s which were trying to take out the CV. There were also a bunch of planes killed down low which were trying torpedo runs. I got a couple Ju88s. If the TG hadn`t been so close to the enemy field it might have survived, but a combination of Shore battery fire and a Corsair which got through to drop a couple eggs did it in.
If you are going to take a TG into harm`s way, then make sure you got the CAP to protect it. In my opinion, a couple Corsairs up high, (this is where the C-Hog would shine) would take care of any problems.
After you got the CAP in place, then start to think about launching TBM`s and heavy Fighters to take out the target. Or if there is nothing showing in the DAR bar, then launch your first strike, then put up CAP for the inevitable response which will come when the opposing side spots the heavy numbers showing up at the target base.
