Correspondent Jeffrey Kaye
of KCET-Los Angeles looks at the latest attempt, and failure, to defend
the United States from missile attacks.

The United States is deploying the controversial, multibillion-dollar weapons program at Fort Greeley. The system is supposed to fulfill a longtime dream of some military planners to protect America from long-range ballistic missile attacks. Army Major Gen. John Holly is in charge of building the system at Fort Greeley. He says since the United States has no way of shooting down incoming missiles, the need for a missile defense system is obvious.

JEFFREY KAYE: Sixty-seven missiles have been installed in silos in Fort Greeley and another one at Vandenberg Air Force Base on the California coast. Here's how the system is supposed to work. If a nation such as North Korea were to launch a missile at the United States, a global web of advanced sensors, satellites, and radars, now in various stages of development, would detect and track it. Commanders would order Fort Greeley soldiers to launch an interceptor missile. At its tip is a device called a kill vehicle. As it approaches the target above the atmosphere, the kill vehicle would separate from the interceptor. Then, using its own thrusters and sensors, it would home in on the enemy missile, striking it at about 15,000 miles per hour. The kill vehicle itself, just 44 inches long and weighing a 140 pounds, carries no explosives.
SPOKESMAN: Verifying we have a threat, GFC -- SPENCER MICHELS: Members of a newly formed unit, the Alaska Army National Guard's 49th Space Battalion, are training to operate the antimissile system. As they do, construction crews at Fort Greeley are building launch silos. JAM. ERIC MAXON: What's happening here is they're drilling out the holes that will ultimately have silos put in them. Following that work they will be ready to accommodate the ground-based interceptors that will be in place here. JEFFREY KAYE: By the end of 2005, the military hopes to have 16 antimissile launchers deployed at Fort Greeley, and another four placed in California. For over 20 years, the Pentagon has been researching and developing a missile defense program. In 2002, President Bush ordered that a system be built and in place by the end of this year. Even as construction of the national missile defense system moves ahead here in central Alaska, fundamental questions persist. Namely, is it worth the cost? Is the testing adequate? And perhaps most importantly, can it really protect the United States against a missile attack?

JEFFREY KAYE: Philip Coyle was a longtime Pentagon insider. From 1994 to 2001, he was assistant secretary of defense, running the office that oversees the testing and evaluation of America's new weapons. In his last months at the Pentagon and since, Coyle has emerged as a leading critic of the missile defense program. He says the U.S. is building a system that hasn't been adequately tested and that won't deliver the security its supporters promise.
JEFFREY KAYE: Since 1997, the there have been eight missile-versus-missile tests over the Pacific, not including Wednesday's failure. Target rockets launched from California have been pitted against interceptor missiles carrying the kill vehicle launched from the Marshall Islands. For Wednesday's aborted test the target rocket was launched from Alaska. The Defense Department says the kill vehicle has successfully found and destroyed enemy targets in five out of the eight previous tests. SPOKESMAN: Copy that RCL. JEFFREY KAYE: But Coyle contends those tests have been tightly choreographed to disguise the system's shortcomings. PHILIP COYLE: The tests that have been done have been more scripted than a modern political convention. The defender, the defending missile system, has known exactly when the enemy missile surrogate was launched, has known what the trajectory was going to be. They have been able to plot out in advance where the two are going to hit. They know what the reentry vehicle looks like and what the other objects in the target cluster look like. One way to think about this is if I throw a rock at you and I tell you exactly how I'm going to throw it and give you plenty of warning, you might be able to bat it away. That's the way the tests have been done so far.
Now, are they the most complex that someone could imagine? No. But we're providing an initial limited capability, not an objective capability. So it's good enough for right now. And the test data that we are getting is extremely useful and will build confidence over time. We will continue to fly against progressively more difficult targets every mission. |

JEFFREY KAYE: In his re-election campaign, President Bush expressed confidence in the missile defense program. Before he took office, the president championed it, prompting increased research and development. His administration has spent more than $25 billion on missile defense.
PHILIP COYLE: That's not correct. The system doesn't have the capability to do that without all of the aids and artificialities that we have had in the tests so far. So, for the president to say, "Bring 'em on. We have a defense" -- that's misleading to Americans and could be provocative to our enemies. JEFFREY KAYE: The Government Accountability Office, the research arm of Congress, has called for more realistic tests. Some Democrats also want a more cautious approach to the program. As the debate continues, missile defense agency is building a floating radar station the size of two football fields to track enemy missiles. It's putting sea launch interceptors aboard Navy Aegis cruisers and it's developing an airborne laser system to shoot down enemy rockets shortly after launch. SPOKESPERSON: Liftoff is confirmed. JEFFREY KAYE: The total cost of developing, building and operating a U.S. antimissile shield could climb to well over a trillion dollars. JIM LEHRER: The Pentagon said it does not know when it will schedule the next missile defense test. |

JEFFREY
KAYE: Alaskans proudly call their state America's last frontier. And
here, 100 miles south of Fairbanks in central Alaska, an army base once
slated for closure is now on the frontier of defense technology and
scientific know-how. 
MAJ.
GEN. JOHN HOLLY: If somebody came into your house and was going to kill
your family, are you going to stand there and watch them? Are you going
to watch that happen, or are you going to try to do something about
it? That's the kind of scenario we are in today. 
MAJ.
GEN. JOHN HOLLY: There is no warhead in our kill vehicle. It is strictly
a kinetic energy collision in space, and the result of that kinetic
energy is such that it causes the opposing warhead to disintegrate.
PHILIP
COYLE: We're not talking about early developmental testing now. We're
talking about deployment, deploying, supposedly, an operational system.
And so far, the system has no demonstrative capability to deal with
a real missile threat. 
PHILIP
COYLE: This is like deploying a new military aircraft without the wings
and the tail and the landing gear. And worse, without testing to see
if this new military aircraft could actually work. 
MAJ.
GEN. JOHN HOLLY: I disagree. Every one of our flight tests has been
against a progressively more difficult target array in front of us.
And they have been against some very sophisticated targets. 
PRESIDENT
GEORGE W. BUSH: We want to continue to perfect this system until we
say to those tyrants who believe they can blackmail America and the
free world, you fire, we're going to shoot it down.
