Finnish radio intelligence

Finnish radio intelligence

The Finnish Radio Intelligence was founded in 1927 by Reino Hallamaa. Through international exchange he managed to quickly build up an efficient organization that proved very successful in breaking the codes and ciphers used by the Soviet Union and other countries. At the beginning of the Winter War the organization employed some 75 persons, by the end of World War II it had a strength of over 1,000.

The Finnish Air Force had its own radio intelligence unit, which focused on intercepting and deciphering Soviet Air Force radio messasges. Its strength was about 300.

The organization was staging the Stella Polaris operation at the end of the war, in order to evacuate intelligence personnel and material to neutral Sweden in case of a Soviet invasion.

After the wars many former officers signed up with foreign intelligence units in order to escape the communist infiiltrated secret poice Valpo, who wanted to investigate and arrest them.

Today the signals intelligence is handled by Viestikoelaitos in Finland.
