How fast do Depth Charges sink

Based on what I saw last night, the campaign ends.

I got caught in the shallows, and it appears that the charge dropped through the sea floor, and then exploded.

I recall one story of a fleet boat in the '50s or '60s that lost power, and was later calculated to have gone below 1000 feet. The pressure hull was damaged enough that the boat was scrapped afterwards, but still not bad for a 25-20 year old boat rated for 400.

Be funny to set them in game to drop at 30ft per sec. Someone should do it with TMO and see how fun it is.


Well for one TMO would become impossible at that point.

That's what I was thinking.



Apart from making life harder (and shorter) for our subs, there are other things to consider. If the charges sink too fast, the ships could end up blowing themselves up. They needed a certain amount of time to reach a safe distance.

Does anyone know if there is a minimum depth the game uses?

That would be the USS Chopper.

That would be the one. I thought it started with a "C", but the only name that came to mind was the Copperfin.

Well, thats one way to sand blast the barnacles off the hull

In das boot, the uboat sat on the Med floor at around 700m, until the british sailed away.

No, it was 280m, which translates to 918 feet. 700m would be almost 3000 feet, not possible even in today's submarines.

In May 1941 U-109 was estimated to have survived reaching 300m, but just barely.

Sorry sailor, you are absolutely right. As they said it i presume it was in feet, but thought, being german, meters. But its been a while. *glug*

I do recall in Walkers book, Walker RN that the U202 'went deep sir' - but unaccountable depth. They recognised the fact that their charges would not go that deep. Instead Walker said, we wait, he must come up at 0002 hrs; and he did! Shelled and sunk. Walker was an expert in ASW even when it was unfashionable.

Depth charges in the game do three things. They explode at set depths, they explode if they touch the submarine and they explode upon hiting the bottom. Hedghogs will explode upon contact with anything larger than a shrimp.

I was hedghoged in shallow water once and the concussion was so great it lift my U-boat to the surface where the crafty submarine though it was surface time and did not return to its below water level after exposing us all to a hail of escort gun fire and promptly sinking 300 yards off shore in Portsmouth Harbor.


Modern submarines can go to 3000. No, I will not explain.
