JCL – totally unjustified and immature comment, obviously you have no idea about how a modern sub works with sonar, go and do your research before making daft comments like that.
"Military-sponsored tests now suggest that low levels of sonar, which do not cause direct damage to whales, could still cause harm by triggering behavioural changes."
"The UK military report details observations of whale activity during Operation Anglo-Saxon 06, a submarine war-games exercise in 2006. Produced for the UK’s Defence Science and Technology Laboratory, it states the results are “potentially very significant”.
The study used an array of hydrophones to listen for whale sounds during the war games. Across the course of the exercise, the number of whale recordings dropped from over 200 to less than 50. “Beaked whale species … appear to cease vocalising and foraging for food in the area around active sonar transmissions,” concludes the report.
It notes, “Since these animals feed at depth, this could have the effect of preventing a beaked whale from feeding over the course of the trial and could lead to second or third order effects on the animal and population as a whole.”
My comment stands. A huge waste of money and resources and that's without even going into the ethics of the navigation system. The morons who man these things deserve everything they get. 80 million more of us are added to the global human population annually and you lot are actually arguing for a bunch of idiots in a giant nuclear powered/armed metal tube. Now that is ironic…
Oh well at least we'll all be able to sleep at night knowing that an extra 1000 square miles of Iranian desert would be incinerated in a potential future nuclear conflict thanks to the sub and the 'brave lads' onboard.
