-As kryptiskt has already pointed out, tactical nuking... isn't. Besides, if things were getting hot, the Swedes (or anyone!) would be fools to keep their naval assets in port; doubly so when those assets are largely autonomous and easily hidden, like submarines. The Norwegian navy also operates a few diesel-electric subs; in cold war days, the plan was to let the Soviet surface fleet enter the fjords, then give them hell - the point being that just about any Norwegian population center or strategic asset is - drumroll - by a fjord. Hence an invading navy would have to venture into the fjords to support the land forces - the fjords packing subs, coastal artillery, torpedo batteries and lots of observation posts to make the stay interesting. Noone thought the Norwegian armed forces could repel a determined aggressor - the idea was to keep the foe busy (bleeding profusely in the process) until NATO allies could arrive. The other Nordic countries probably had similar strategies.
