I doubt that's the case. If the gun is 40 feet in the air and trained flat the shell is going to hit the water in less than two seconds. The 4.7" DAMS gun had a muzzle velocity of 2330 fps, which means that it will hit the water at about 800 meters. The problem is that the 4.7"/45 could depress 10 degrees, which means that for it not to hit the U-boat is going to have to be right alongside. Most of the different DAMS guns were similar in elevation.

I think they just got surprised, the same as HMAS Sydney.
