!Question; Isn't destroying a enemy submarine as simple as sending a diver down to attach a high-explosive device to it?
Can they see people on under-water radar?

Submarines are afster than divers.

Divers make noise, detected on passive sonar.

Active sonar screws divers.

screws em' how?
Special Gear.
Can they fir torpedos on something behind them? Submarines I mean... can they?
What is the sub gonna do if they detect a diver, run??

Active sonar is sending out "pings". It's like setting off a concussion grenade inside a person's helmet.

Some modern subs can get up to 45 knots or faster; a diver can't catch that.

A submarine can go much deeper than a diver.

hmm, i was also thinking air-sea missles.
don't question how we would find the sub yet - that the easy part.

Finding a sub is sometimes very easy, sometimes very hard. In my experience, it really depends on the people involved on each vessel.

oh, well what about my ideal? really simple and esay it seems...

Which? Air-to-sea missiles? They've been around for ages.

no, not air-to-ship

i'll never get anywhere at this rate...

Torpedoes go to all sorts of depths. The ASROC and various systems will deliver a torpedo further out, giving extra range.

What more do you want?

how about depth charges, they use those anymore?...big explosive drums in the water...
oh well..


Can underwater ships or board go as fast as jets?
I imagine underwater ones can but the bots will eventualy capsize...

I'm not sure if anyone uses those any more.

No sea vessel goes as fast as aircraft can.

Very groovy, but they can't get as fast as aircraft and stuff.

No, you'll never see a diver swimming after a submarine going 30 knots 10,000 feet underwater.

How many subs go down to 10,000 feet underwater?

http://www.history.navy.mil/photos/sh-usn/usnsh-s/ssn589-n.htm

Only a half dozen or so deep submergence research vehicles.

Not really 'subs' in the sense being discussed.

:cool:

Okay, okay, not 10,000 feet.

Adam: Which? Air-to-sea missiles? They've been around for ages.

my grandfather was on the Polaris development team :)

the men were vary patriotic and wanted to fly, but the one man who was made an example of had quit, only to be drafted back at less pay

1 knot is equal to...

dictionary.com:

(Naut.) (a) A division of the log line, serving to measure the rate of the vessel's motion. Each knot on the line bears the same proportion to a mile that thirty seconds do to an hour. The number of knots which run off from the reel in half a minute, therefore, shows the number of miles the vessel sails in an hour. Hence: (b) A nautical mile, or 6080.27 feet; as, when a ship goes eight miles an hour, her speed is said to be eight knots.


a website listing some rate conversions:

knot (nautical mile per hour) *(5.144444 E-01)=meter per second (m/s)

I thought a naughtical mile was equal to some latitude or longitude subdivision, like a thenth of a degree or something vaguely like that.

Yes, the nautical mile is equal to one the distance covered by one arc-minute of longitude along the equator.
