Kystfort

Would anyone by chance know the weapons of Grotsund Fort, during the cold war? I have not found any information pertaining to the base besides it has become a quay for oil ships.

Thanks

Short answer (there were several changes during the period from establishing Grøtsund fort in 1945 to it's decomission in 2001):

The primary weapon for the period 1950-1990 was a controllable minefield with about 125 mines (US Mk 1 mod 0 system, which was replaced by a new Saab-system (IDA) in 1998 although it never reached operational status).
To protect the minefield there was a anti-surface gunbattery with four 10,5 cm SK C/32 guns. For air defence there were 4 x 20 mm (Rheinmetall) and 4 x 40 mm (Bofors) guns. The fort also had standard close-defence installations.

Thank you!
