Transcript of Pentagon Briefing: Next Missile Interceptor Test Delayed Until July
Defense Department spokesman Ken Bacon said a minor problem discovered
in the Raytheon National Missile Defense (NMD) interceptor has delayed
the next NMD test from June to July.
Some rewiring work had to be done by the manufacturer, Bacon said, but
"it should not have any impact" on the recommendations that Defense
Secretary Cohen will make about the program to President Clinton later
this summer.
The subject came up when a reporter asked about a letter written by a
Massachusetts Institute of Technology (MIT) physicist who has
suggested that his analysis indicates that the NMD program is
unworkable. Bacon responded by saying, "We, from the beginning, have
tried to hew to a very ambitious program without cutting corners that
will compromise the quality of the National Missile Defense system or
its chances of success."
The Ballistic Missile Defense Organization (BMDO) is preparing "a
detailed response" to the letter, the spokesman said, but BMDO
officials "clearly disagree" with its premise. One of the problems,
Bacon said, is that the MIT analysis is based on a flight test with a
Boeing interceptor that is no longer used in the program.
"One of the biggest challenges faced by the National Missile Defense
program is to discriminate between warheads and decoys," he said. But
Bacon said the current Raytheon interceptor is doing "a good job"
discriminating between the two platforms.
Bacon said there will be one more interceptor test -- the one that had
been scheduled for June 26, but now expected in early July -- before
the information the president needs to make his decision about future
deployment is sent forward by Cohen.
Asked about the Chinese reaction to the U.S. NMD program, the
spokesman said U.S. teams have been sent to Beijing to discuss the
capabilities of the limited system. He said discussions led by U.S.
officials will continue to emphasize the point that the limited NMD is
designed to counter a very limited attack against the United States by
a rogue-type nation.
"We are not building this (defensive) system against the Chinese
(strategic missile) system," Bacon said.

DoD News Briefing
Thursday, May 18, 2000
2:00 p.m. EDT
Presenter: Mr. Kenneth H.
Bacon, ASD PA
Mr. Bacon: Okay. Thank you all very much. I have a few announcements
here:
First, just to remind you, tomorrow, 50th anniversary of Armed Forces
Day. Secretary Cohen and President Clinton will be out at Andrews Air
Force Base with General Shelton, between 8:45 and 9:45, to begin the
Joint Service Open House that will run through the weekend.
Second, I'd like to announce that Secretary Cohen announced today that
the president has nominated Army Lieutenant General Tommy Franks to
the appointment of general. And he will become the commander in chief
of our Central Command, which of course is responsible for the Middle
East, and will be based at MacDill Air Force Base in Florida.
Q: Which branch of the service is --
Mr. Bacon: He is an Army general. And he will succeed, of course,
Marine Corp General Tony Zinni, who's currently the commander in chief
of CentCom.
Q: When does that take effect?
Mr. Bacon: I don't know, but it's sometime this summer. I don't know
the exact date.
Q: What's General Franks' first name?
Mr. Bacon: Tommy. And his middle initial is R.
General Franks is currently the commanding general of the 3rd U.S.
Army at Fort McPherson, Georgia.
And that's all I have in terms of announcements, and I'll be glad to
take your questions.
Jamie?
Q: Since Charlie's not here, can I start off?
Can we get your response to the analysis provided by Dr. Ted Postol of
the Massachusetts Institute of Technology, in which he claims that the
-- his analysis shows that the basic technology and physics behind
this national missile defense program is unworkable and that it's been
misrepresented by at least one of the companies involved?
Mr. Bacon: Well, first, let me say that I have read Dr. Postol's
letter. However, I have not read all four of the attachments that came
with the letter.
The Air Force or, I should say, the Ballistic Missile Defense Office
is in the process of doing a line-by-line analysis of the letter. They
have not completed that yet. So my comments will be somewhat limited
and not an encyclopedic response to the letter.
But let me just say a couple of things.
First of all, obviously, one of the biggest challenges faced by the
National Missile Defense program is to discriminate between warheads
and decoys. This is something to which we've devoted a lot of time and
will continue to devote time in the future. There are basically three
technological parts to the solution to the discrimination problem. The
first is the quality of the sensors. The second is miniaturization,
the compactness of the weapons, speed of the weapons, et cetera. And
the third is computers.
Now, in the third area -- there have been improvements in all areas,
but in the third area, the improvements over the last decade, or last
five years, have been particularly dramatic increases in computational
speed and power. And this is important because ultimately the
computers have to be able to process a lot of information picked up by
the sensors very, very quickly and compare what they're seeing to
information that is loaded into data banks for the sake of comparison
in making a choice between whether an object in space is a warhead or
a decoy.
We're building, as you know, a system that's designed to respond to a
limited threat; that is, a relatively small attack or an attack
involving a relatively small amount of missiles. It's not the type of
attack that we would get from a country that has a huge force, such as
Russia does. It's not built in response to the Russian force at all.
We know that a Russian force, or any force that's even much smaller
than the Russian force, but still large, would quickly overwhelm the
system we're contemplating.
We assume that the type of attack right now may not have the most
sophisticated decoys, but obviously decoys can be improved over time,
and will be improved over time. So we're very aware of that, and we're
working very hard, particularly on the three areas that I mentioned.
Now, let me just say one thing directed at Dr. Postol's letter.
He focused primarily on one test, so-called the Integrated Flight Test
1A. That test occurred several years ago, and it involved an
interceptor made by Boeing TRW. The prime contractor, or the lead
systems integrator for the National Missile Defense program is, in
fact, Boeing. When Boeing came to make the choice of the kill vehicle,
the interceptor vehicle, it did not choose its own kill vehicle. It
chose instead one made by Raytheon.
Now, Dr. Postol's letter focuses primarily on this first test that
involved the Boeing TRW interceptor. Now we are using interceptors,
and have for several tests, they've been using interceptors made by
Raytheon. The next test -- Integrated Flight Test 5, for instance --
will involve a Raytheon interceptor, as did 4, and I believe 2 and 3
as well involved the Raytheon interceptor.
The Raytheon interceptor differs from the Boeing interceptor in
several respects. The Boeing interceptor, as I understand it, had only
an infrared sensor. The Raytheon interceptor has a different, more
advanced infrared sensor, but it also has an optical sensor. So it has
two ways to acquire targets, both optically through a visual sensor,
and infrared, which senses heat.
Second, it uses each one of these -- and this goes back to the
computers -- has to use a computer program based on an algorithm
that's designed to process large amounts of data very quickly. They
use different algorithms. I can't get into the details of this because
I don't understand it myself. But if you would like somebody to
explain the difference between the Bayesian algorithm that was in the
Boeing interceptor and the Dempster-Shafer algorithm, which is
supposed to be better for these purposes that it's the currently used
Raytheon interceptor, I am sure we can find somebody who can explain
these mathematical formulae and algorithms.
But in short, Dr. Postol focused primarily on a test involving an
interceptor that is no longer part of the program.
Now, having said that, I don't want to diminish the challenges that we
face in target discrimination. That's clearly one of the things that
we're continuing to work on. We believe that the current interceptor
is doing a good job in discriminating between warheads and decoys.
Q: If I could just have one follow-up on the Dempster-Shafer algorithm
-- (laughter) -- please? (Laughter.) No, seriously -- (laughter) --
Mr. Bacon: I wonder if you could just give me -- I mean, do you think
there is a mistake in it? (Laughter.)
Q: Yeah. (Laughter.) I think it might have just been my calculator.
(Laughter.)
If I understand -- I mean, my understanding of the science behind this
is probably not much better than yours or probably less than yours,
but as I understand Dr. Postol's argument, he says that it doesn't
matter whether or not you are talking about another test with a
different algorithm; that what his analysis showed is that the data
that you can collect from space, through these various systems under
any algorithm, is simply not possible to make the kind of
discrimination that the Pentagon says it's having some success in
doing, in discriminating between a warhead and a very simple decoy.
Mr. Bacon: Well, we clearly disagree with that. We wouldn't be
spending a billion dollars -- billions of dollars on developing a
National Missile Defense System unless we had some degree of
confidence that we can make that discrimination and make it in time to
be useful.
But clearly, this program is still a young program. There have been
four integrated flight tests so far. There are several dozen more
planned, and they will be occurring over a long period of time. And
one of the things we'll be doing is refining every element of the
program as we go along.
As I said, the BMDO, the Ballistic Missile Defense Organization, is in
the process of doing a detailed analysis and response to Dr. Postol's
letter. This is a letter that reached the press before it apparently
reached the government, so we haven't had quite as much time to
analyze it as some other people have, but we are doing our best to
analyze it as quickly as possible.
Q: And one other follow-up: Is the next test still set for June 26th?
Mr. Bacon: We had set June 26th as the target for the next test.
We've known for several weeks that it's probably going to be later
than that. It'll probably be sometime in early July rather than June
26th. The reason for that is that there was a minor problem discovered
in the interceptor, some rewiring had to be done. It was sent back to
Raytheon in order to complete that rewiring. Now the rewiring is done,
it's been tested, they have confidence in it and they are in the
process now of marrying the interceptor to the rocket and shipping it
to Kwajalein Island. That took, this fix, took about a week, and so
we've had to delay the test by several days.
Q: And does that affect your time table for making a recommendation to
the president by --
Mr. Bacon: It should not have any impact whatsoever. We always said
that there was a window for the test that opened on June 26th. Our
hope was to do the test at the first day of the window, but we always
recognized the possibility that it could slip a day or two.
Q: In light of the questions that Professor Postol raised and the
importance of the decision, wouldn't it make sense to have the work
that's been done so far and the testing and so on be reviewed by an
independent body of scientists who would be, you know, capable of
passing an independent judgment --
Mr. Bacon: Well, I gather that Dr. Postol is already reviewing it.
Q: Well, but I think that that's what he's suggesting to the White
House, or urging the White House to do, is to have an independent body
review this.
Mr. Bacon: We, from the beginning, have tried to hew to a very
ambitious program without cutting corners that would compromise the
quality of the National Missile Defense system or its chances of
success. And I think we found a pretty good balance, but we still have
one more test to do before the president has the information that the
secretary will send him fora decision and we will evaluate the program
as we go along.
One of the things the Air Force -- the BMDO will do is go through Dr.
Postol's letter and decide how serious the charges are. But we have
been working very hard on the discrimination problem for some time and
will continue to do that.
Q: Are you open now to an outside review, or do you -- do you oppose
--
Mr. Bacon: Well, I think it's premature at this stage. I'm not ruling
it in or I'm not ruling it out. It's not clear to me, and I don't
think it's clear to the Ballistic Missile Defense Organization, that
we need an outside review at this time.
Clearly, there is a lot of information about this program publicly
available. Dr. Postol presumably got his from public sources. There
has been extensive congressional testimony on this, been several
fairly detailed press briefings in this room on it. This program is
proceeding with a huge amount of public attention and surveillance,
and this is appropriate. This is a very important program. It's an
important program to our nation's defenses. And it's appropriate that
it be scrutinized, and it is being scrutinized.
We will obviously proceed in a way designed to give the public the
greatest possible confidence in the program and in a way that gets the
information to the decision-makers as quickly as possible and as
accurately as possible. And we'll have to find the right balance
between those two goals.
Q: Regarding Flight Tests 3 and 4, which were the last two intercept
tests --
Mr. Bacon: Right.
Q: -- do you know why BMDO originally planned to use about 10 decoys
in each of those tests and then scaled them back to use only one decoy
that was of a different size and intensity than the actual warhead?
Mr. Bacon: I do not myself know. I believe that General Kadish
addressed that publicly here, as a matter of fact. But I don't know.
We'll try to get the answer. We'll get the answer. I don't know the
answer myself.
Yes?
Q: Mr. Bacon, do you have anything on the military exercise Dynamic
Mix, since it's starting tomorrow from Italy all the way to Greece?
Mr. Bacon: I don't have anything beyond what I said on Tuesday.
Q: And how do you define the present status above the Aegean, the
insular part, the territorial waters and the airspace during the
upcoming exercise? Will -- your forces will honor the present status
quo and the rules of (inaudible)?
Mr. Bacon: I don't know the answer to that question. I mean, we do
military exercises with our NATO allies all the time in the
Mediterranean, and I assume we'll follow the normal procedures,
whatever they are.
As you know, Greek and Turkish forces are participating in this
exercise, along with the forces of more than 10 other NATO nations. So
we'll follow the normal procedures.
Q: I raise this question because the Turkish government has already
requested that the so-called gray or contested areas of the Aegean,
like Imia, should be excluded from the exercise, and that's why I
would like you to clarify DoD position on the issue, since your forces
will deploy to the entire Aegean Sea, all the way to the port of
Thessaloniki.
Mr. Bacon: Well, NATO forces will deploy, and I'm sure that NATO has
found a solution to this.
Yes?
Q: Ken, the Iraqis said yesterday there were some civilians injured
and killed in a U.S.-British airstrike. Do you have anything that
would corroborate that?
Mr. Bacon: We do not. I've seen reports in the Iraqi press, and they
emanate from the city of An Najaf, I guess it's spelled, A-n N-
a-j-a-f. That's two words: A-n space N-a-j-a-f. All we know is that
coalition aircraft, both American and British, were flying in the
area; they were attacked by anti-aircraft and possibly missiles. They
did not respond to that particular attack. They dropped no ordnance.
And therefore, if there was any damage on the ground or if any
civilians were killed, it probably happened by friendly fire, by what
Iraq shot up and ultimately came back down again. We have -- we did
not drop ordnance in this particular place at this particular time.
Yes?
Q: Yes, sir. Pardon me if I'm not terribly descriptive and accurately
descriptive. To follow the question I asked Mr. Cohen yesterday: Mr.
Bacon, can we assure the Chinese or point out to the Chinese that
their missile force is able to be routed onto any target they choose
without being within range of our National Missile Defense, to be
located in the Aleutians? In other words, can they get their missiles
around this defense? And is that what we're saying when we say it will
have no effect on their strategic deterrence?
Mr. Bacon: First of all, we do not anticipate that China or Russia or
any other country is going to fire missiles against us. And if they
were to do that, it would have a disastrous consequence on the
attacking country. But we don't anticipate this is going to happen.
Second, however, we're not in the business of telling countries how to
route their missiles against the United States. Third, we have sent
teams to China and discussed our National Missile Defense program with
them and made the point that this program is designed to counter
attack, counter a very limited attack against the United States of the
type that could be launched by a rogue nation with a very small number
of missiles.
Q: Such as North Korea?
Mr. Bacon: Such as North Korea, possibly Iran not too far in the
future, maybe Iraq sometime.
We have had discussions with the Chinese about this, and we will
continue to discuss it with them.
Q: I guess I should ask this -- go a little further and just once
again ask, can missiles coming out of China to any targets anywhere,
any reasonable targets, can they be intercepted by this system that
the U.S. intends to place in Alaska? Or is it just out of range or
what?
Mr. Bacon: We don't have a national missile defense system yet, so I
am not going to talk about the capabilities of a future system. We
have described it in very general terms: It's designed to deal with
limited attacks from rogue nations.
President Clinton has not made a decision to deploy such a system, and
he'll be looking at the information later this summer and will then
decide what to do.
Q: Ken --
Mr. Bacon: Sure.
Q: -- just to follow up on that, if I could? I think we understand the
argument that's been made publicly, as far as reassuring the Russians
that national missile defense doesn't affect them. But what's the
argument that you can make to the Chinese, who have dozens --
supposedly -- missiles that can reach the United States, that their
deterrent would not be affected by this?
Mr. Bacon: We have been designing this system -- we use the -- sort of
the code word "rogue nation." I think that that symbolizes two things:
One, it suggests a country that might not be deterred by the
deterrence that has worked in the past, and still works, against
Russia and China and other countries. We have a very formidable
nuclear force now that is built not to attack, but to deter anybody
from attacking us. We believe that the Chinese, as the Russians, are
susceptible to this argument of deterrence and in fact will be
deterred from using their weapons. We are not so sure about smaller
nations with different governmental systems.
Second, we are building this system to protect us from the type of
blackmail that we might be held hostage to in a situation -- for
instance, where Iraq attacks a neighbor; we begin to mobilize a
coalition, as we did in 1990, to go in and respond, and they say:
"Wait a minute.
If you do this, we're going to hold one of your cities hostage."
These are -- this blackmail argument is one that Secretary Cohen has
made many times. We do not believe that a country that is susceptible
to the normal deterrent arguments would want to use a blackmail
approach against us.
Q: My question is -- I mean, the Chinese want to have a nuclear
deterrent. They --
Mr. Bacon: They have a nuclear deterrent.
Q: Well, they have dozens of missiles. And you're proposing a system
that could shoot down dozens of missiles, or I think the number that's
being used is tens of missiles, which to a layman makes it sound like
you're going to have a system that could defeat the current Chinese
nuclear force. And so I'm asking what reassurance you can offer the
Chinese that they will still have a deterrent the same way that you're
attempting to reassure the Russians on that point? Or is there no --
do you not want to reassure the Chinese about this?
Mr. Bacon: Well, I mean, we have talked to the Chinese about this, and
the Chinese have said publicly that they don't ever plan to be the
first to use nuclear weapons, in which case they have nothing to fear
from a national -- from a purely defensive force that would only
respond to the use of nuclear weapons.
Q: But you understand that they want to have a deterrent. I mean, I
don't --
Mr. Bacon: I understand that they want to have a deterrent, and I
believe they --
Q: I feel I haven't explained the question correctly --
Mr. Bacon: You have explained the question, and all I can tell you is
that we've had discussions with China. And we do not -- we are not
building this system against the Chinese system. But we can't -- you
know, all we can do is tell them why we are building the system and
the very -- the types of limited threats -- much smaller than the
Chinese threat, even -- that we have in mind.
Q: But you can't tell them just -- and I'm not trying to heckle you
here, but you cannot tell them for some reason "This system wouldn't
affect your deterrent, this system wouldn't be relevant to you." You
cannot tell them that at this time.
Mr. Bacon: We can tell them that this is not a -- that this is a
system designed against an extremely small force, smaller than their
force.
Yes.
Q: Mr. Bacon, the Senate yesterday finally by vote set up a date for
the removal of the U.S. forces from Kosovo, and a similar one is
intended on in the House. Any comment?
Mr. Bacon: Well, we are against these provisions. I will point out
that the House defeated back in March a provision that would have
required forces to come out of Kosovo, I believe in June, sometime in
June if certain thresholds of European participation weren't met.
Yesterday they had a different vote, and they voted on a provision
that set the date in 2001, I believe it was April in 2001, but also
gave a delay factor that would allow the president -- if the
thresholds weren't met, would allow the president to delay for 90
days.
It's still unacceptable. It puts our deployments on an uncertain
basis, which makes it difficult for us to convince our allies that we
are going to work with them reliably to bring stability to Kosovo and
the Balkans generally. It would allow us to be manipulated by Mr.
Milosevic or the Serbs on the one hand, or perhaps the Albanians on
the other hand by creating problems around the time of the deadline.
For a host of reasons it is not intelligent to put these artificial
deadlines on troop deployments. So we are opposed to the House version
and obviously opposed to the Senate version as well.
Yes.
Q: As we're talking here, the chiefs, the chairman and the U.S.
Strategic Command are scheduled to be testifying on the Hill about
nuclear force levels necessary. Can you just tell us what their
message to Congress is? Is it that the Pentagon doesn't want to go
below 2,000 warheads, or -- is there any way to --
Mr. Bacon: I think their -- I have not read the testimony that they're
going to be making. And as you say, they're going to testify soon. My
understanding is that they will say basically what Secretary Cohen
said several days ago in this room, that the chiefs and the Defense
Department in general agreed to the range of 2,000-2,500 warheads that
were set in Helsinki between President Yeltsin and President Clinton
-- then-President Yeltsin and President Clinton. That is the range for
bringing, for reducing the nuclear arsenals of Russia and the United
States.
Now, we're operating -- we're coming down to the START I range, which
is about 6,000 countable warheads. START II range would be
3,000-3,500. The START III range would be 2,000-2,500. And they will
announce that they reviewed that range and accepted it. That's not
new.
Q: Okay. Thank you.
Mr. Bacon: Thank you.
