As far as I know, the loss of 18 Ju88s from KG 51 on June 22, 1941 has nothing to do with the SD2. Some were shot down by Russian fighters and most were victims of flak and ground defenses over the target. When the SD2 was dropped, the Ju88s were flying at an altitude of 20-50m and were therefore an easy target. The Ju88 of KG51 attacked their targets in the Rotte/pair that day, which reduced the risk of their own bombs hitting them. The SD2 with Dopp.Zdr.41 was only armed when the opened wing rotated 5-6 times. How is that supposed to work if the bomb gets stuck in the Vemag. If a stuck one still falls out of the Vemag when landing, how is it supposed to be armed? The SD2's biggest problem was the duds. These were located on the attacked airfields and advance roads, which they later used themselves. These unexploded bombs cannot be defused and often detonate at the slightest movement.
