Technology has always found its greatest consumer in a nation's
war and defense efforts. Since the last attempts at a "Star Wars"
defense system, has technology changed considerably enough to make
the latest Missile Defense initiatives more successful? Can such an
application of science be successful? Is a militarized space
inevitable, necessary or impossible?

Laser Shoots Down Rocket for First Time By Jim Wolf
WASHINGTON (Reuters) - A powerful laser developed jointly by the
United States and Israel has shot down a rocket in a breakthrough
test of defense technology, the Army said on Wednesday. The test was
the first in a series before the high-energy laser, designed by a
team led by TRW Corp., is to be handed over to Israel to help
protect its northern border with Lebanon against short-range rocket
attack.
``We've just turned science fiction into reality,'' Lt. Gen. John
Costello, head of the Army Space and Missile Defense Command, said
in a statement released by his headquarters in Huntsville, Alabama.
He said the shoot-down, Tuesday at the Army's White Sands Missile
Range in New Mexico, showed ``directed energy'' weapons systems like
lasers ``have the potential to play a significant role in defending
U.S. national security interests worldwide.'' Israel's deployment of
the weapon would mark the world's first of an anti-rocket laser. The
United States, which says it has no immediate plan to use it, is to
ship the system to Israel by next October after tests against
multiple rocket launches. The capability to shoot down a target with
an experimental airborne laser was first demonstrated by the United
States in the late 1970s, said John Pike, director of the space
policy project at the Federation of American Scientists. A laser --
short for Light Amplification by Stimulated Emission of Radiation --
is an intense, highly directed beam of energy. It works like
focusing the sun's rays through a magnifying glass to start a fire.
The ground-based, short-range, air defense system, which cost $186
million to develop, is formally known as the Tactical High Energy
Laser/Advanced Concept Technology Demonstrator (THEL/ACTD). For the
first test of THEL's defensive capabilities, a single Katyusha
rocket carrying a high-explosive warhead was fired from a rocket
launcher inside the test range. Seconds later, the laser system,
located several miles away, detected the launch with its
Israeli-built fire control radar, tracked the streaking target and
locked on to it with its high-energy beam. ``Within seconds, the
10-foot-long, 5-inch diameter rocket exploded,'' TRW said.
``Basically, it fries the explosive in the warhead until it explodes
harmlessly in the air,'' added Thomas Romesser, deputy general
manager for laser programs at TRW's Space & Laser Programs
Division in Redondo Beach, California.
Highly focused energy can cross great distances at the speed of
light with minimal loss of intensity. Even a moving target may be
heated to temperatures like those on the surface of the sun,
Romesser said in a telephone interview. Theoretically, such a beam
could knock out missiles at distances up to thousands of miles. That
was the idea behind the space-based missile defense shield like the
``Star Wars'' system first suggested by President Ronald Reagan on
March 23, 1983. Major Gen. Isaac Ben-Israel of the Israeli Ministry
of Defense was quoted by TRW as saying THEL had taken ``the crucial
first step to help protect the communities along our northern border
against the kind of devastating rocket attacks we've suffered
recently.'' THEL is a ``transportable'' system contained in several
truck-sized shipping containers. The system stems in part from a
commitment made in April 1996 by President Clinton to then Prime
Minister of Israel Shimon Peres to aid Israel in developing a
defense against Katyusha rockets fired by Hezbollah guerrillas from
southern Lebanon. Clinton is due to decide by November whether to
begin deploying a ground-based national missile defense against what
U.S. intelligence says are potential threats from countries like
North Korea, Iran and Iraq. Lasers are not due to play any role in
the initial phase of any such deployment. Instead, the targets would
be smashed by ``kill vehicles'' atop ground-based interceptor
missiles.

The U.S. Air Forces is already studying the feasibility of
weaving lasers into layered defenses against ``theater'' ballistic
missiles. Eventually, the technology could play a role in the
controversial U.S. plan to build a shield against limited strategic
missile attack, U.S. military officers say. The Air Force is
developing an airborne laser system for use on its 747-400F aircraft
that could become part of a future ''theater,'' or regional, missile
defense, designed to be operational by 2007.

To every guys who wants want to concern about safty:
the best way is burning out all unnessary chemical, bio weapon.
it avoids to hits in right target in U.S.A

A missile defense system would be dangerous and ruinously
expensive. Why would a rogue state fire a missile at us, with the
return address there for all to see? Wouldn't it be safer and
cheaper for a rogue state to use other delivery systems? Search
freighters. Search every bale of marijuana - there is your likely
delivery system. $60 Billion already spent, thrown down this rathole
boondoggle. Why not have spent this money on our schools? Why not
have spent this money on effecient transit systems for our cities?
Think about it the next time you are stuck in traffic.

If it were that pie in the sky no one would be worried. Other
countries are concerned because they think we might pull it off.
John, I couldn't agree more. If they thought is was useless and a
waste of billions of dollars, they would not raise a peep. They are
grunting and groaning because they realize that if any nation can
pull it off, its the US.
Last weeks shoot down (melting) of a Katyusha rocket by the
Army's high energy laser was simply "smashing".
The video is on the BBC website and it worked beautifully. The
laser will be deployed on Israel's northern border very soon.
Excellent for short and medium range threats however the laser is
not capable of long range interception of missiles in powered
flight. In the future, perhaps satellite lasers will hold more
promise. I would rather see the US push ahead with defensive systems
rather than deploying more nuclear warheads.
