since the intended 56,000-ton h and j-class battleships were never completed, the guns that had been designed for them were used as coastal defense artillery during the second world war. at least eleven of the guns were produced; eight were sited in norway (one was sunk en route), and the other three were used in poland near danzig. soon after their first training shots, the polish guns were moved to france and sited near sangatte and renamed battery lindemann in honour of the fallen captain of the battleship "kapitän zur see" ernst lindemann.
