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?

6/25/01 2:52pm cites an excellent article -- important enough to
issues of deception and lying by the administration -- discussed
here on this thread, that I'm posting it in full, with some bolding
for emphasis, and some comments.
June 25, 2001 Pentagon Study Casts Doubt on Missile Defense
Schedule By JAMES DAO http://www.nytimes.com/2001/06/25/politics/25MISS.html
"WASHINGTON, June 24 — An internal Defense Department study
concluded last year that testing on the national missile defense
program was behind schedule and unrealistic and had suffered too
many failures to justify deploying the system in 2005, a year after
the Bush administration is considering deploying one.
"The August 2000 report from the Pentagon's Office of
Operational Test and Evaluation, only recently released to Congress,
offers new details about problems the Pentagon has encountered in
developing antimissile technology. And it raises questions about how
quickly an effective system can be made operational.
"The Pentagon is studying proposals to deploy a limited system
— but one that would violate the 1972 Antiballistic Missile Treaty —
as soon as 2004. In recent weeks, Secretary of Defense Donald H.
Rumsfeld has indicated a willingness to deploy a system before tests
have been completed if an attack seems imminent.
"But as an example of unrealistic testing, the report cited an
October 1999 test in which a Global Positioning System inside a mock
warhead helped guide an intercept missile toward a target over the
Pacific. That test was successful, but two more recent flight tests
failed.
"None of those tests used the kinds of sophisticated decoys
that a real ballistic missile would use to confuse an antimissile
system, the report said. Instead, the decoy in each test was a large
balloon that did not look like a warhead and that the kill vehicle's
sensors could easily distinguish from the target.
"The report also asserted that the Pentagon had not even
scheduled a test involving multiple targets, the likely situation in
an attack. And it found software problems with a training
simulator that made it appear as if twice as many warheads had been
fired at the United States as had been intended in a 1999
exercise.
"The simulator then fired interceptors at those "phantom
tracks," and operators were unable to override it, the report
said.
"The report, which President Bill Clinton read just before
deferring initial construction on a missile system last September,
acknowledged that the program was still in its early stages and was
progressing well on some fronts. But it concluded that unless
testing was significantly accelerated, at significantly higher cost,
the program would not be ready for use against real attacks for
several years.
"Deployment means the fielding of an operational system with
some military utility which is effective under realistic combat
conditions," the report states. "Such a capability is yet to be
shown to be practicable for NMD," or national missile defense.
"Officials with the Pentagon's Ballistic Missile Defense
Organization disputed parts of the report, saying that the Global
Positioning System used in the 1999 test did not guide the kill
vehicle to the target. They also contended that the simulator did
not fire at "phantom" missiles.
"They acknowledged software problems with the simulator but
said those flaws had been fixed. And they asserted that future
tests, perhaps starting next year, would involve tougher situations,
including more sophisticated decoys, multiple warheads and different
trajectories.

"We fully intend to stress the system to its maximum
capability," Lt. Col. Rick Lehner, a spokesman for the
organization, said. (Comment: light colonels are in a vulnerable
position, and what they say as spokesman ought to have limited
weight.)
"But skeptics of missile defense said the report clearly
showed that even the most advanced antimissile technology needed
years of testing to work out unforeseen bugs. Without such testing,
they warned, the system would be at best ineffective and at worst
dangerous.
"The problems have been different each time," said Philip E.
Coyle, a former assistant secretary of defense and director of
operational testing, who helped write the report. "In each case, the
thing that failed was something you'd have liked to have taken for
granted. It just shows how hard this stuff is."
"The report, which members of Congress plan to make public
this week, is expected to fuel a contentious debate over how swiftly
a missile system should be deployed and how much money should be
spent developing one. ( Comment -- somehow gisterme
didn't know this. )
"Mr. Rumsfeld has argued that the United States should deploy
a system quickly to dissuade its rivals from trying to acquire
ballistic missiles. He contends that no weapon system works
perfectly and that a limited missile defense can be gradually
improved and expanded.
"During his recent trip to Europe, Mr. Rumsfeld gave NATO
defense ministers a paper stating that the United States "will
likely deploy test assets to provide rudimentary defenses to deal
with emerging threats."
"The Pentagon has also been studying a proposal from Boeing,
the lead contractor on a missile defense system, to install a basic
antimissile system involving five interceptors in Alaska by 2004.
The system, which would violate the ABM treaty, would use
existing radar and rockets as interim technology until
more advanced systems were ready. ( Comment: Interesting to do
bookeeping on what this "existing radar" can do, in comparison to
radar performance in the open literature - and admissions about
angular resolution made here.)
" But in an appearance by Mr. Rumsfeld on Capitol Hill on
Thursday, Democrats vigorously questioned those proposals and
expressed strong reservations about speeding up a system they said
remained unproven.
"The Democrats have also raised concerns about the Bush
administration's threat to withdraw from the ABM treaty if Russia
refuses to amend it. Mr. Bush has argued that the treaty prevents
the United States from testing promising technologies, like
sea-based or airborne weapons.
