Dear Christopher.
You said..."though I have found it humorous to sit
and listen to others about such matters, I cannot help but point out their
mistakes."
Allow me to do the same.
I know the difference between radar and
sonar.
You said...."Radar,.......That will be ineffective
in location of submarines"
There certainly were a lot of submarines found by
radar on the surface and sunk during WW2. That's why the germans were
expermenting with the rubber coated sub to try and defeat the
radar.
Radar has been used extensively to locate
submarines on the surface (as with any ship on the surface) during WW2 and
since. I said the germans in WW2 were expermenting with a rubber coated sub to
defeat detection by radar. I stand by that statement.
You ASSUMED I made a mistake and that I said radar
when I meant sonar because you were thinking of a submarine SUBMERGED. You
did not read carefully what I said.
I said and meant radar.
You said...."Sound, Regardless of what coating is
on it"
You assumed I meant the rubber coating would defeat
sonar. That is not what I said.
I also stand by my statement that I believe
eventually sound waves will be able to be bent around objects and render them
invisible to sonar much like our stealth fighters defeat radar, and
therefore we should not put all our eggs in the sonar basket.
I apologize for the disagreement, but you assumed
things I did not say. Please read it again.
Don't feel too bad. I make mistakes all the time.
I'll probably make one again soon! Lol. Just ask the guys here! I thought
covering your batteries with oil in a battery pod would contaminate the
acid. Made a big mistake on that one.
But I try not to get too cocky. I learned that when
you do you get the most egg on your face.
Kindest Regards,
Bill Akins.

Radar, it stands for Radio Detection and Ranging.
That will be ineffective in location of submarines.
Sonar, it stands for Sound Navigation Ranging, an acoustic pulse
in the water and measures distances in terms of the time for the echo of the
pulse to return. That would be consider an active ping.
Passive is when instead of send out a pulse you turn on the second half
and receive other pulse form other vessels.
SOUND. Regardless of what coating is on it, will vibrate
through the water. Which will pulse through the water and can be
detected by any type of sonar. (a good example is a sound powered
phone)
I
apologize for the disagreement, but however, though I may not have very much
technical knowledge on the construction of a submarine, I do have military
knowledge, and though I have found it humorous to sit and listen to others
about such matters, I cannot help but point out their mistakes.

Even in WW2 the germans were experimenting with
a rubber coated submarine to defeat detection by radar.
Seems to me that we should not put all our
trust in sonar. All that has to be done is to bend that sonar wave around an
object and it will not bounce off it to return to the sonar man on board.
Hence....invisiblility.
We used similar technology in our stealth
fighter aircraft. Who would have thought years ago that a plane could defeat
radar?
Kindest Regards,
Bill Akins.

Seems there is allot of dislike of the U.S. Navy.
However speaking off the record, it is very doubtful that any kind
of sub
surface vessel could be used effectively against a US Carrier,
due to
several reasons...most of which should be common sense...and
some which will
not be spoken.
Regardless of no prop to move
the vessel, if moving, it will be detected by
sonar, regardless of
means or propulsion, just like any other object in the
ocean.

Re: [PSUBS-MAILIST] Seahorse news
Dubai is one of the safest
place in the world to live.
Just not forget that the vehicle mostly
used by terrorist is a car, toyota
or
mitsubishi. The last concern
of designers (car, plane , boat) and now
submarines is to the least
criminal use of their designs.
Criminals have endless possibilities
from toaster to people to plant bombs
so i
am not going refrain
myself against innovation because of criminals.
What is criminal is to
not let ourself prepared against such attacks, i
designed
a
submarine specially to prevent underwater attacks which has not
received
any
interest from the all powerfull US Navy. so i did my
duty and i am not going
to
open a bakery instead of selling subs
because somebody, someday might use a
sub
to blow up
something.
however Al quaida reportedly already has acquired mini subs,
which i know
are
not from me.
My scubajet is a breakthrough in
scuba diving, it is a low profile light
diver
propulsion vehicle in
a ergonomic backpack including a BC with no hoses or
consoles sticking
out (HUB), you control propulsion with a bite switch in
your
mouth
piece which
makes it hands free. optional is a small LCD mask screen to
display info,
depth, speed, air capacity.
There is no props, it is
true that if used with a rebreather it is difficult
to
detect,
remember that most diver detectors are passive, listening to
noises
under the water, but rather ineffective anyways in a port
because of heavy
activity generating noises, active sonars to detect
divers are also rather
ineffective is such shallow water.
Best
regards
Herve
