An Iowa in Hood's place at Denmark Strait

What if an Iowa-class battleship replaced Hood at Denmark Strait?

The answer expects a much worse fight for Bismarck and no repeat of Hood's explosion, while acknowledging the threat of German 15-inch fire.

The hypothetical substitutes an Iowa-class battleship for Hood at Denmark Strait. Iowa is expected to avoid Hood's catastrophic explosion and bring radar-directed 16-inch fire against Bismarck. Bismarck's own 15-inch shells would still be dangerous. The potential to engage earlier is tied to radar and gun range, with the precise range advantage still uncertain at this point.
