How fast do Depth Charges sink

[Red Devil]

I do know that the Japanese, for quite some time, thought no sub could go below 200 feet.

No problem. It wasn't really directed to you, but to the room in general, anyway.

That does make sense. With the codebreaking efforts, perhaps someone knew and passed information down the line, suggesting strongly that below 200 feet was a good place to hide?

Gato Balao and Porpoise could do 300, and a bit. Tench 400 as I recall.

Well for one TMO would become impossible at that point.

Well if they are set to drop 30 ft/S then I'll just stay shallow and let them blow up below me.

That brings an interesting point up. What happens when a Depth Charge hits bottom in game? I tend to stay away from the shallows at all possible times(Thu why I normally do Pearl Based careers) so i've never see what happens.

The listed test depth and what they actually "could do" are not the same. American boats were expected to do 1-1/2 times the test depth, and sometimes did more. The Balao class was listed as having a test depth of 400 feet. USS Pampanito went below 600 feet on her first patrol.

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.

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.
