Where 1/MAA 118 was supposed to take care of guarding the gap in the minefield under the coast, 2/MAA 118 task was to cover the half of the Skagerrak from the danish side.
For that purpose four huge ship guns with a caliber of 38 cm was placed on the cape of Hanstholm - The so-called Bismarck guns.
The guns should be emplaced in four big bunkers with a ground area of appx. 1.900 m2, and made of appx. 6.600 m3 steel concrete.
Every gun emplacement was equipped with its own power supply, living quarters, munitions depots, water supply etc. So every gun could be sealed off completely and operate independent of the other guns in the battery.
A common two-storey fire control bunker for the four guns were also build in the area, but every gun could in an emergency situation commence its own fire control.
Building the four emplacements began in November 1940 and was fully equipped and ready to fire in September 1941.

When the shells and charges should be transported into the gun turret, it was first put into some special locks, which protected the munitions from shooting flames.
When shells and charges were delivered throught the flame lock, they were transported to the elevator in the turret on a small waggon which went all the way around the gun turret.
From the waggons the shells and charges were loaded into the elevator and hoisted up into the turret.
