Really? I just tried a test with DW. This time a Type 42 DD at 2900 yards only shows up as thin line in 688i's normal BB. I went to NB to try to classify it and it was classified as either 2 torpedoes...weird.
In the end the DD detected me much faster than I did and launched 2 torpedoes at me missing me because I was too close.......
So I say most publications LIE

. DD more quiet than a sub?
I have some screenies but too lazy to put them:rotfl:
I was travelling at 5 knots bottom at 9,000 somethin probably feet. No thermal layer.
