Russia's Missile Defenses Eroding
Gaps in Early-Warning Satellite Coverage Raise Risk of Launch Error

MOSCOW�Russia's early-warning defense against missile attack, a key aspect
of the hair-trigger doctrine of nuclear deterrence, is deteriorating
because Moscow cannot replenish the array of satellites it needs to monitor
U.S. missile silos and submarines, according to Russian and Western
security analysts.

For several hours each day, Russian military commanders cannot see any of
the U.S. missile fields, nor can they monitor the most dangerous threat to
their own forces -- U.S. Trident submarines submerged in the world's
oceans, these specialists said.

Russia has not launched an early-warning satellite in nearly a year, they
added, and U.S.-Russian plans for sharing early-warning data, announced
last September by Presidents Clinton and Boris Yeltsin, have not been
implemented. Such cooperation involves highly sophisticated equipment and
the transfer of ultrasensitive defense information, analysts say, and a
legacy of distrust persists on both sides.

Although the Cold War has ended, Russia and the United States remain on
constant nuclear alert. Both sides say that if attacked they will unleash
massive retaliation, even before enemy warheads arrive; the strategy is
that such a stance will discourage any first strike.

But the threat of retaliation requires accurate early warning, and without
it, Russian decision-makers are blindfolded. Some Western specialists say
the growing gaps in the area covered by Russia's early-warning satellites
have increased the risks of a serious miscalculation, because Russian
commanders will have less time to decide if a launch report is real.

There have been several close calls. In September 1983, the Soviet
early-warning system sent a false signal to ground stations that a U.S.
missile attack was underway. After a few anxious minutes deep in a Soviet
defense bunker, the mistake was recognized by an officer on duty. In
another case that highlights the early-warning risks, the launch of a
Norwegian scientific rocket in 1995 triggered a false alarm that was
reported all the way to Yeltsin.

At the time of the 1983 alarm, the Soviet satellites positioned to detect
U.S. ballistic missile launches had been on station for only about a year.
Launched into a high elliptical orbit, the satellites did not look directly
down at Earth; rather, they peered at an angle, depending on infrared waves
to identify the hot exhaust of a rocket against the black background of
space.

To keep tabs on U.S. missile fields, an array of satellites was needed.
Their space tracks followed one after another, sweeping over the known
missile locations in the United States; but they were prone to drift from
their orbits and had to be replaced often.

The full early-warning system of that era had nine satellites. On the day
of the false alarm, there were seven in orbit, according to Paul Podvig, a
research associate at the Center for Arms Control, Energy and Environmental
Studies here. Podvig said the seven satellites were sufficient to cover all
the U.S. missile fields because the full overlay of nine was designed with
some overlap.

That same system is still in use, but because of its crippling financial
problems, Russia has not put a single early-warning satellite into orbit
since last April. Some existing satellites ceased working as recently as
last year, and, according to Podvig, the system now has only three active
satellites -- less than half the number at the time of the 1983 alarm and
just a third of the full constellation.

The Soviets created a second satellite system in the late 1980s -- this one
in geostationary orbit, meaning that each of these satellites remains above
one place on the Earth's surface. Two of these are still functioning,
Podvig said, with one sited to cover some of the gaps in the original array
of satellite.

But gaps remain, however. Every 24 hours, the high elliptical satellite
system is blind during two periods; one is nearly six hours long, the other
about an hour long, Podvig said. Even with the help of the geostationary
satellites, there is a daily gap of about three hours, he said.

"Over the last five or six years, Russia kept the configuration working all
the time," Podvig said. "But it started disintegrating at the beginning of
1998. The situation in the last six years wasn't good, but they had
reserves. They kept it working. Now, they have used up those reserves. The
problem is serious."

There is some uncertainty among Western and Russian experts about the
capabilities of the satellites in geostationary orbit. At issue is whether
one of these satellites, Cosmos-2224, is capable of looking directly down
at the world's oceans, where the Trident submarines patrol.

Podvig said he believes it can look down at the North Atlantic -- Tridents
also patrol the Pacific -- while Theodore A. Postol, a professor at MIT,
has questioned whether it has look-down capability at any ocean. Without
this capacity, Postol said, Russia would be blind to sea-launched missiles.
"Russia has no space-based early warning against the most potent threat its
land-based forces face, the U.S. Trident submarine-launched ballistic
missiles," he said.

Postol noted that Russia's system of ground-based early-warning radar has
also been degraded because many installations were built on the Soviet
periphery -- outside Russia -- and are now in independent states. An
important radar station in Latvia was closed last August and has not been
replaced, and there are other gaps, as well. Postol has mapped "corridors"
in which missiles could be launched at Russia that would not even show up
on the existing radar screens. One such avenue runs from the Pacific, where
most Tridents are based, into the heart of Russia from the Far East.

"There are large parts of the Russian forces that could be attacked from
the Gulf of Alaska and would be destroyed without Russia even knowing an
attack was underway," Postol said in an interview. "Moscow could be
destroyed within four to five minutes of the radars seeing the incoming
warheads."

The situation is risky, Postol said, because it could drive Russia more and
more toward making a quick decision to retaliate -- one that would be based
on less reliable information.

But Podvig said he is not as worried as Postol about Russia's early-warning
problems. "If you consider Cold War scenarios, a lack of early warning is a
really bad thing. You can come up with all kinds of first-strike scenarios.
But I'm not that pessimistic. My view is that, even if Russia has no
early-warning capability, no radars, no satellites, and still relies on
intercontinental ballistic missiles and launch-on-warning, in any crisis,
Russia will still have to be taken seriously," he said.

So far, little has been done to reduce the threat of nuclear
miscalculation. Russia and the United States have pledged to re-target
missiles away from each other, but that could be reversed quickly in a
crisis. Bruce Blair, a security analyst at the Brookings Institution in
Washington, has argued for "de-alerting" Russian and U.S. nuclear forces,
effectively taking them off hair-trigger status, but the idea has yet to
win official favor.

With reduced early-warning capability, Blair said, Russia "is losing its
ability to distinguish between real and imaginary nuclear threats. The
United States could be the big loser in this situation."

At a Moscow summit last September, Clinton and Yeltsin announced plans to
share early-warning missile launch information. "It was a good first step,"
said Postol, "but the administration hasn't done anything to implement it,
and they have no vision of follow-on steps."
