First of all the SwAF never used a hyphen in its designation. The Ca 313 was known as the B 16A, S 16A/B, T 16A and Tp 16A depending on its role. In this case S 16A is correct.

In all four S 16A are recorded during this time frame to have been lost, three known to German interference, and the other one most probably not.

S 16A Fv no 3335 F11-14 disappeared 14 May 1944 shot down by Bf 109G-8 over the Baltic, probably by Obfw Gerhard Frenzel aus Plauen who claimed a DB-3, one killed and three rescued.
S 16A Fv no 3304 F11-8 disappeared 15 May 1944 during search for Fv no 3334, probably shot down by Fw Paul Schalk 6./JG 5, four killed
S 16A Fv no 3319 F11-61 disappeared 23 May 1944 11km west of Anholt, probably shot down by Uffz Mittelstadt 10./JG 1 who claimed a Douglas, four killed
S 16A Fv no 3345 F11-34 disappeared 7 June 1944 over the Baltic, probable cause mist mistaken for low clouds and flight into the water/loss of control with the same result, four killed.

I don't believe the incidents were supressed at the time. The Swedish long range reconnaissance units were snoping around in the Baltic to have first hand data of what the German (and Soviets) were doing in the area, and it feels reasonable to believe that all personal knew about the risks and even if probably no one liked said risks, I doubt anyone backed out.

So far my Swedish sources. Most correspond to your details, except who shot down Fv no 3335. I have no unit for Frenzel aus Plauen but he could well be from NAGr 8. Did that unit claim two aircraft?
