Sonar used in WW2.
I remeber read somewhere,that the sonar was ineffective at excesive speed of 12-13 knots. So that always destroyes had less that 12 knots to detect submarine
Is this true ?

I've read that as well, yet there doesn't seem to be a definitive answer that I can find now. I've also read that by 1945 the US and UK had upped the usable speed to 18 knots. Can't find solid evidence of either one now.

"Might be..."? That's fascinating! Thanks for the link.
Early on the document talks about streamlined sonar domes upping the effective speed from 10 to 15 knots, but while it implies this happening prior to the US entry into the war it doesn't give specific dates for the actual adoption of the equipment, or for the British development of it. It also claims that we were detecting surfaced submarines, and I've never heard that claimed anywhere. It would be interesting to find out more about this.

does anyone know if any U-boats or any sub for that matter, that operated in the atlantic that were lost to hurricanes off of africa or the atlantic? Im battening down the hatches here in NYC for irene and got me thinking did any subs get caught in the "perfect storm" after all past and present naval warfare.
