Brooke is essentially correct.
The British and the Americans tried on a number of occasions to Level Bomb with Lancs or B-17/B-24s. Although medium to high level bombimg works well on stationary targets, the relatively manuverable ships were much more difficult to hit.
With a dive bomber (SBD, TBM, etc) the plane had a more vertical path to the ship, bomb was dropped lower and adjustments could be made easier in the aircraft with the ship having less time to re-act.
Still a difficult prospect considering the ACK and other variables affecting both the plane and the ship.
wojo is coorect in that there is much less "lead" needed for a diving fighter than a level bomber at 12,000 doing 220 MPH.
And yes this is just a game:)
