Command Corridor

The Facility’s Brain
Between two atomic bomb-proof blast wave locks lies the facility’s brain, the command corridor. The corridor houses what was once the bttery commander’s office, the headquarters for the facilaity’s highest-ranking officer.

Inside, you’ll also find an instructor’s room, where the battery commander and his closest men planned exercises for the conscripts. Additionally, there is a telephone exchange and the quartermaster’s room, where administrative tasks such as payroll and leaves were handled.

Further down the corridor is the fire control center designed for anti-aircraft combat. Initially, three 40 mm automatic anti-aircraft guns m/48 were installed with the ARTE 703 fire control system and a 40 mm automatic anti-aircraft gun m/36. The anti-aircraft defense was modernized in the 1970s. The fire control system was replaced with ARTE 725, and a 40 mm automatic anti-aircraft gun m/48 or m/36 was decommissioned. It was intended for anti-aircraft combat but could also be used for sea and ground target combat.

The operator unit for ARTE725 consists of a control panel with a TV monitor and a computer. The target is tracked using an automatic TV target tracker. From the operator unit, sighting and shooting data are calculated.

At the end of the command corridor is the combat control and communication center, from which a number of people obtained intelligence from various parts of the facility and other adjacent military units. This intelligence was written down on paper, then sent through a hatch in the wall to the combat control center. Still present here is the orange-lit wall that projects one of the major Swedish military technological achievements of the 1980s, the STRIKA combat control system.

In the combat control center, they had the overall responsibility for the battle, and from here, they were responsible for leading the defense of the entire fortress. This was facilitated by the intelligence received from the communication center.

The measuring stations that ensured the reconnaissance and fire control functions for the firing KA batteries at Storråberget and Havstoudd were very well protected and were almost impossible to detect. In total, there were five external measuring stations of different types to use if the batteries with regular radar systems were knocked out. The measuring stations had above-ground radar antennas and armored domes with TV cameras and laser rangefinders. The personnel in the command corridor consisted of 15-17 people.
