The class mounted its four main guns on the centreline, with two aft, one forward, and one among the funnels. Its aft 88 mm weapons served for anti-aircraft defence and action against smaller vessels. Brummer and Bremse used that fighting power while laying mines and escorting German minesweepers. Their successful minefields repeatedly burdened British operations even when they sank no ship directly, because suspected mines still had to be found and cleared.

Centreline guns and dual-purpose 88 mm weapons let Brummer protect itself, escort minesweepers, and operate as more than a one-task mine carrier.
