Bismarck had radar controlled fire systems but no carriers to help.
Bismark had an 82cm (wavelength), 8kW RADAR system.
American battleships had 3cm (wavelength), 50kW RADAR systems.
As a general matter, shorter wavelength means greater accuracy in detection, identification, tracking, and ranging. Antenna size and power output are also relevant.
The Combined Fleet pages have all manner of interesting information about WWII ships.
