    That's a pretty noisy ship...What is it?...An English VTOL carrier or a Collins class SS? ;)

    So it hears every ship that exits a port? That's pretty sensitive. How does it filter the noise?

    I've always dreamed of replacing the diesel in my boats with a small reactor and turbine setup. Imagine the electricity, heat and propulsion you'd get... for YEARS on end.

    Military Submarines almost never employ active sonar which would have probably detected shoaling conditions and kept that sub off the hard. Active sonar would give their position.

    A modern sub counts on passive sonar, listen only, and has sophisticated computer programs to filter noise and interput. They can indeed hear ship sounds at increadible distance, as well as identifying ship type, and course and speed by dopler.

    Well, the ASTUTE was on sea trials when the grounding occured. That's the second time in two years they've grounded a sub in that area. Not really what one would expect for a Navy with such an extensive background.

    And now a small digression for you gun and history lovers ;) - was Jutland really a matter of british bad luck, or was it rather a matter of the german Imperial Navy's ability?

    Yes, though even from before Jutland they had charts that might have kept them off the hard. Less of a comment on the sonar more on carelessness - it was particularly unfortunate that it was a very public accident.

    There was a RINA talk on this last year but I didn't make it. One could argue that the RN earnt themselves a fair chunk of 'bad-luck' by failing to learn the lessons of Jutland. I'm sure that there are plenty of other folk that have a much finer set of opinions on this though.

    I watch this back in July, it struck me that it was a pretty much a propaganda piece - whatever, they're impressive vessels.

    We (Canada) are now the "proud" owners of four of their diesel-electric cast-offs from years gone by. One of them even came with a pressure hull "dent" from another collision.
