Two Canberras were acquired by the Swedish Air Force from the RAF and these were modified to Canberra T.11 by Boulton Paul. After delivery, both aircraft were secretly modified in Sweden for eavesdropping on primarily Soviet, Polish, and East German military radio transmissions. The Canberras were given the designation Tp52, and taken into service as test aircraft, until they were replaced by two Tp85 Caravelles in 1971. Serial 52002 was flown to Malmen into retirement on 25 January 1973.

During recent restoration the original rounded nose cone has been replaced by a pointed one, as used by the RAF with the Canberra T.11 to train Gloster Javelin radar operators.

Sweden did buy two second hand Canberras for trials. This one is preserved in the excellent Malmen museum

Two modified Canberra B.2s were delivered to Sweden's F8 wing at Stockholm - Barkaby in 1960. This one was mainly a research platform but the other, like the Varsity on the right, was used for electronic intelligence work. Both Canberras also undertook missions to test the alertness of the Swedish air defences, popping up after extremely low flying over the Baltic.
