HÅRSFJÄRDEN / THE SUBMARINE WAR
The 1982 hunt, national attribution and the evidence problem beneath Swedish waters
Sweden’s 1983 commission said foreign submarines were in Hårsfjärden with certainty — but acknowledged that nationality was not proved by clear evidence.

- DOCUMENTED / SOURCE-BASED
Later official reviews revisited both the evidence and Sweden’s anti-submarine response.
