Russian military leaders have expressed concern about US plans
for a national missile defense system. Will defense technology be
limited by possibilities for a strategic imbalance? Is this just SDI
all over again?

-- I'll check.

6/12/01 10:23am was neither formal agreement nor
disagreement - - - - - but I was espressing sympathy for
almarst , and making a point about politeness that I think we
probably agree on.

What is the stated application of the laser tech you
described?
Here's a start: http://www.trw.com/productsandservices/main/0,1104,4_39_134_146_210^5^210^210,00.html#
They used to have cool movies of them shooting down the missles,
several at once. But just removed them, for whatever reason.
Lasers are line of sight. It will be a year or two before they
can be put in airplanes, and longer for satellites. Therefore, only
ground based ones are available. And therefore only short range
missles are vulnerable. The range is over 10 km for rockets and
jets. The power is well over 1 megawatt.
Where in the ICBM's arc is the laser supposed to magically
eliminate the target?
During the boost phase. The big powerful ones above can actually
destroy the katusha warhead itself, but lasers lend themselves to
blowing up the rocket. All they have to do is punch a hole in the
thin skin. The airbourne one that will be tested next year has a
range of hundreds of miles.
Knocking out a hardened warhead is much more difficult than a
booster, so that is where the immediate use will be.
As far as my grasp of lasers, I am the optoelectronics editor
at a trade magazine for electronic design engineers. I have a
small grasp of lasers and optoelectronics.
And you don't know about the existing ground based lasers. And
that we have already sold them to foreign governments? And that they
have never ever missed a missile? My my.
What is your experience in the field?
Only rshowalter "knows".

"Big lie" strikes again.
Now, just so I can be informed -- what angle through the
atmosphere does a ground base lasar need to shoot down a missile,
before warhead separation? How close does the lasar have to be to
target?
If you're close enough, of course, a lasar isn't needed for boost
phase. A 50 caliber machine gun will do.

Here's the link to the cool movies of it shooting down the
rockets. Found it.

I don't know about your "trade magazine" but it has even been in
Popular Science I'm told.

"Big lie" strikes again.
From one of your old "associates" like me?
Now, just so I can be informed --
That's why I'm here, to "inform" you.
what angle through the atmosphere does a ground base
lasar need to shoot down a missile, before warhead
separation?
The stated plan is to put it in an 747 at 35,000 feet. It will
shoot down many hundreds of miles and hit the booster "shortly"
after launch. I would guess, shortly after clearing the clouds. The
angle is pretty flat. 6 miles up and hundreds of miles away.

Absorbtion problems? Vibration problems with the airplane?
Anybody blushing when they predict this will work?

Getting pretty shrill and desperate, aren't we?
Fooled Popular science too. And the newspapers of the world. And
the Israeli government. And the Federation of American Scientists.
Etc. Etc. Etc.
Don't stop now. This is fun.
