Bismark had radar.
Bismark had surface search RADAR only. Iowa class had fire control RADAR as well.
Bismark’s Fire Control was so far ahead of it’s time that Bi-Planes were able to sink it because the Bismark’s guns overshot at them.
Yes...and they had lots of beer on board, but doesn't mean the sailors were drunk.
Bismark's radar was nearly laughable. I think they were called FUMOs or something. Max range was under their max gun range and couldn't pick up multiple targets. In fact, if waves got over 15-20 feet, radar was useless. She could hardly detect more than one target at the same time, let alone track it; and bearings were not very accurate; range finding was better done from the command deck. The Germans, did however, have superior optics and triple and quadruple sighting systems to make up for the A-scope (very poor)radar.
