The Kriegsmarine explored guided weapons too late

Did the Kriegsmarine investigate guided weapons for naval service?

Yes, though the work remained at an early stage and never matured enough to appear on operational German warships.

Germany's army and air force developed guided weapons that reached limited operational use late in the Second World War. The navy also showed interest in applying guided weapons to attacks on ships and naval formations. Its work remained at an early stage and did not mature into a practical shipboard system before the war ended. The absence of such missiles from late German warship proposals reflects timing and development limits rather than a total lack of naval interest.
