I’ll check again, maybe, but last time I did naval strike I found the convoys vary greatly in their effectiveness. On Dover the cargo ships comprising the convoys for the default axis side are death zones, but I was able to fly up and down the allied convoys in a Stuka or He 111 and then limp home with minor damage. It’s similar on Moresby: I can make torpedo runs flying torpedo bombers from the Japanese CV, but going the other way is insta-death
