Analysis of the Effects of Energy Spreading Loss and Transmission Loss on Low Frequency Active Sonar Operations in Shallow Water or The relationship between a submarine's maximum speed and its evasive capability :-) ...... and, fantastic find, seems to be a little extended version of "The Third Battle", relased in PDF, I found here paragraphs that not exist in WWW version.

I've always use FAS as a good source of informaiton for american ship stats. http://www.fas.org/man/dod-101/sys/ship/index.html

And there are a few articles on the Harpoon3 site that are interesting reads as well http://www.harpoonhq.com/waypoint/ - very nice link , try for example "In Peril On the Sea: The ASCM threat and countermeasures"

to be continued...

P.S. Some articles I had are not online anymore, or I can't find them with Google, so I put them on my personal page for you, some were saved without pictures that's why they are lacking pictures now.

Please reply once in this thread and put YOUR interesting links if you have any !

Very nice read, there are few other interesting papers on same page, one of them is PDF version of "The Third Battle" I mentioned. Your article describes that after noise levels of soviet subs decreased by about 35dB from mid 60's to mid 90's, and similar quietening was reached by third-world conventional subs, detection ranges decreased from previous HUNDREDs miles down to FEW kilometers at best (!! - and the people still vote for several miles of det ranges for creeping quietest subs in the world against each other :-/ was this realism mod or not ?), and passive sonars, even best ones, developed in Cold war against deep water nuclear subs, are seen as not enough to fight with such threats... Even when they can be improved still, still quieter subs can be build too and det ranges would vary from few hundred meters or less to few kilometers which is knife fight no one would want to get into... something like new generation super-maneuverable fighter planes with high-off boresight missiles and helmet mounted sights - if you get into merge in such fight, you have roughly 50% chance to die, no matter how good your plane is... who sees first wins, no matter what plane, $120M or $20M. You don't want to get into that close fight, you want to fight at distance. So new sensors, for example low-frequency, LPI, wide aperture active sonars are needed... to get those det ranges back into at least torpedo-range class (>10-15nm).

Here's another interesting one - describes just this concept: THE EMERGENCE OF LOW–FREQUENCY ACTIVE ACOUSTICS AS A CRITICAL ANTISUBMARINE

I got to say ya have quite interesting way to compare submarines to jets. Thats quite impossible thing to do. And when ya get into dogfight, no matter what missiles equipped (AIm9x or Python-5 which both have very good off boresight capabilities), its not certain "one shot one kill" scenario.

And hi to everyone.

Bit of a necro, but I just picked up DW and hunted through the threads here for info, mods etc. The link above to 'The Third Battle' no longer works, but I managed to google an alternative link, as its a great article:

Almost five years after the last reply to this thread...
Just in case anyone was trying to find link no. 2 from the list - "Understanding Oceanography". The Wayback Archive still has the pages:
