Also known as switch P801, was placed on the right side of the central armament panel (column between the pilot legs, just above the bomb fusing panel). Its purpose was to fire eight small explosive charges to separate all the bracing struts (four per tube) of the rocket tubes from the wing.
WGr 21 tubes were jettisonable. Can we have this feature implemented in AH?
BTW, the switch to the left side was to "arm/select" BOTH rockets (there is no way to select a single one, salvo should be fixed to 2) that were then fired at the same time pressing the top/left button of the stick (B2 trigger).
