01 / DOCUMENTED CORE
Start with what the record can carry.
Operation Stella Polaris was the 1944 evacuation of Finnish signals-intelligence personnel and material to Sweden as Finland faced the possibility of Soviet occupation.
FRA’s own history documents longstanding Finnish–Swedish signals cooperation and the evacuation of roughly 750 intelligence-linked people to Sweden. Later Swedish SIGINT history should be connected to this through institutional context, not treated as the same operation.
02 / CASE RECORD
What is established.
The evacuation plan was codenamed Stella Polaris.
In September 1944 roughly 750 people connected to Finnish intelligence were evacuated to Sweden.
The transfer included expertise and material relevant to signals intelligence.
