China to Shoot at High Frontier
U.S. Intelligence: China to conduct test of more powerful anti-satellite
weapon capable of hitting GPS, spy satellites, but after U.S. election
BY: Bill Gertz
October 16, 2012 5:00 am
China’s military is set to conduct a test of a new and more capable anti-
satellite missile that United States intelligence agencies say can knock out
strategic satellites in high-earth orbit, according to U.S. officials.
However, a recent intelligence assessment said the test of the Dong Ning-2
direct ascent anti-satellite (ASAT) weapon is being delayed in an apparent
effort to avoid upsetting President Barack Obama’s reelection bid, said
officials who spoke on condition of anonymity.
Intelligence reports from September and this month revealed China will test
fire the new DN-2 missile from a ground base sometime in early to mid
November.
The missile is described by intelligence agencies as a high-earth orbit
interceptor designed to destroy satellites by ramming them at high speeds.
The intelligence reports called the new missile a strategically significant
counterspace weapon, said the officials familiar with the reports.
Testing a high-earth orbit anti-satellite missile would represent a major
advance in China’s satellite-killing capability, which has been underway
for more than a decade. High-earth orbit, also known as geosynchronous orbit
, is the location of major communications and navigation satellites, which
orbit at a distance of between 12,000 miles and 22,236 miles from earth.
China’s last ASAT test in 2007 destroyed a low-earth orbit weather
satellite about 558 miles in space, causing an orbiting debris field of tens
of thousands of pieces of metal that U.S. officials say will threaten
orbiting satellites and human space travelers for 100 years.
U.S. officials said it is unlikely China will conduct an impact test of a
kinetic kill vehicle against an aging weather satellite as occurred in 2007,
although the possibility of a second, major debris-causing test cannot be
ruled out.
Instead, officials said the test most likely will be a demonstration of a
precision-guided direct ascent missile flying out tens of thousands of miles.
“If the United States loses the strategic high ground of high-earth orbit [
from a Chinese high-altitude ASAT missile], we are in real trouble,” said
one U.S. official.
U.S. Global Positioning System satellites, used for both navigation and
precision missile guidance, are located in medium-earth orbit, or about 12,
000 miles, and thus would be vulnerable to the new DN-2.
Whether or not the test is successful, development of the new high-altitude
DN-2 ASAT reveals that China’s military is planning for future high-orbit
space warfare despite seeking international agreements banning weapons in
space.
China’s January 2007 ASAT test drew protests from the United States and
other spacefaring nations, who saw it as a major threat to satellites used
for both military and civilian purposes. That test also produced tens of
thousands of pieces of space debris which threaten satellites.
A second possibility is the DN-2 missile test will be fired against a target
missile, as occurred in 2010 as part of a joint Chinese ASAT-missile
defense test.
Pentagon spokesmen declined to comment on the DN-2 ASAT program.
Michael Pillsbury, a former Reagan administration defense policymaker,
stated in a 2007 report to Congress that Chinese military writers advocated
covert deployment of sophisticated anti-satellite weapons system like the
kind now being developed by the People’s Liberation Army for use against
the United States “in a surprise manner without warning.”
“Even a small scale anti-satellite attack in a crisis against 50 U.S.
satellites—assuming a mix of targeted military reconnaissance, navigation
satellites, and communication satellites—could have a catastrophic effect
not only on U.S. military forces, but on the U.S. civilian economy,” said
Pillsbury, currently with the Hudson Institute. Chinese military writings
also have discussed attacks on GPS satellites that are located in high-earth
orbit, he stated.
ASAT a top-secret program
China’s anti-satellite missile system is a key element of the communist
state’s growing arsenal of asymmetric warfare weapons, and remains one of
Beijing’s most closely guarded military secrets.
Defense officials have said that with as few as 24 ASAT missiles, China
could severely weaken U.S. military operations by disrupting global
communications and military logistics, as well as by limiting celestial
navigation systems used by high-technology weapons. Such an attack also
would severely degrade U.S. intelligence gathering efforts against global
targets, a key strategic military advantage.
A U.S. official familiar with reports of the ASAT test said China’s delay
in conducting the test until after the Nov. 6 election is a sign Beijing
wants to help President Obama’s reelection campaign. “It implies they’d
rather have him reelected,” said the official.
The Obama administration has adopted conciliatory policies toward China’s
military buildup and its large-scale human rights abuses. Critics say the
administration also failed to hold Beijing accountable for its unfair trade
practices and currency manipulation.
The administration’s questionable policies were revealed by a 2009 State
Department cable that quoted Secretary of State Hillary Clinton as saying,
“How do you deal toughly with your banker?”—a reference to China’s
potentially coercive leverage over the United States through its large
holdings of U.S. debt securities.
Richard Fisher, a Chinese military affairs specialist, said little is known
publicly of the DN-2 missile. However, the DN-2 may be China’s designation
for an ASAT missile and kill vehicle combination mounted on launchers dubbed
KT-2, or KT-2A. This ASAT weapon is based on DF-31 or DF-31A road-mobile
intercontinental ballistic missiles, respectively.
“ASATs derived from the KT-2 and KT-2A space launch vehicles have the
potential to reach high earth orbits used by many strategic U.S.
surveillance, communication, and navigation satellites,” said Fisher, with
the International Assessment and Strategy Center.
Fisher said in 2002, during a military show in China, the KT-2A was touted
by Chinese officials as having a 2,000-kilogram payload that could reach
high-earth orbits.
“Since its appearance a decade ago, the KT series of space launch vehicles
presaged what we now know, that a key Chinese strategic goal has been to
deny outer space as a sanctuary to support American military operations,”
Fisher said.
A KT-1 microsatellite launcher was displayed at the Zhuhai air show in 2000,
and “it was fairly obvious that this could become the basis for an ASAT,
and it was used as the basis for the SC-19 ASAT demonstrated successfully in
January 2007,” Fisher said.
Because China will not join a verifiable space control agreement, “
Washington has little choice, if it is to continue to deter China militarily
, but to build far greater redundancy, passive and active defenses for outer
space,” he said.
China ASAT caused space debris
U.S. officials estimate that China’s 2007 ASAT test that destroyed an aging
weather satellite in low-earth orbit now accounts for 45 percent of all
space debris in low-earth orbit.
After a year of stonewalling by China on the test, an official U.S. demarche
, or protest note, was sent to Beijing in January 2008. According to a copy
of the note made public by Wikileaks, the protest warned the Chinese
government, “Any purposeful interference with U.S. space systems will be
interpreted by the United States as an infringement of its rights and
considered an escalation in a crisis or conflict.”
“The United States reserves the right, consistent with the [United Nations]
Charter and international law, to defend and protect its space systems with
a wide range of options, from diplomatic to military,” stated the protest,
made by then-U.S. Ambassador to China Clark Randt.
A joint State Department-Pentagon report to Congress on export controls made
public in April states that China is “developing space-based methods to
counter ballistic missile defenses of the United States and our allies,
including anti-satellite (ASAT) weapons.”
“As China advances in operational space capabilities, it is actively
focusing on how to destroy, disrupt, or deny U.S. access to our own space
assets,” the report said.
China is developing and refining its ASAT weapons as part of a “multi-
dimensional program to limit or prevent the use of space-based assets by
potential adversaries during times of conflict,” the report said.
“In addition to the direct-ascent [missile] ASAT program, China is
developing other technologies and concepts for kinetic and directed energy
for ASAT missions,” including electronic jamming of satellite
communications and lasers that disrupt satellites, the report said.
ASAT weapons “have significant implications for anti-access/area-denial
efforts against the United States in Taiwan Strait contingencies,” the
report said. Those weapons and capabilities are being developed by China as
a means to force the U.S. military out of Asian waters and territory and
make it more difficult for U.S. forces to get into the region during a
conflict, such as a defense of Taiwan. Other anti-access area denial weapons
include anti-ship ballistic missiles, cyber warfare capabilities, and
submarines.
Defense Intelligence Agency director Lt. Gen. Ronald L. Burgess told
Congress in February that “China successfully tested a direct ascent anti-
satellite weapon (ASAT) missile and is developing jammers and directed-
energy weapons for ASAT missions.”
Burgess said that as “a prerequisite for ASAT attacks, China’s ability to
track and identify satellites is enhanced by technologies from China’s
manned and lunar programs as well as technologies and methods developed to
detect and track space debris.”
Another ASAT test by China will likely undermine the Obama administration’s
controversial space arms control proposal, introduced in January. Many in
the Pentagon oppose the International Code of Conduct for Outer Space
Activities over concerns it would place limits on U.S. space capabilities.
U.S. lagging in counterspace
Despite China’s continuing development of space weapons, the administration
has done no research or development into so-called counterspace weapons and
other capabilities that could deter China from its ASAT and anti-satellite
laser and jammer arms, according to military officials. The opposition is
based on the administration’s preference for arms control negotiations and
agreements as a major element of its U.S. national security policies, the
officials said.
Frank Rose, deputy assistant secretary of state for arms control, said in a
speech in April that the space code of conduct would include legally
nonbinding “transparency and confidence-building measures.”
However, a Pentagon Joint Staff assessment of the space code of conduct
concluded that U.S. adherence to the code’s provisions would hurt U.S.
space operations in several areas.
The Pentagon’s National Security Space Strategy from 2011 makes little
mention of counterspace weapons. It states that U.S. policy is “to dissuade
and deter” others from developing space weapons, without providing
specifics.
The Pentagon indirectly demonstrated an ASAT capability in 2008 when it used
a modified ship-based SM-3 anti-missile interceptor to shoot down a falling
, low-earth orbit spy satellite that was considered a danger because its
fuel tank might have passed through the atmosphere and landed on earth.
Cables detail PRC’s first ASAT test
According to a classified Jan. 12, 2010, State Department cable made public
by Wikileaks, China conducted its most recent ASAT test on Jan. 11 of that
year.
According to the cable, an ASAT missile designated SC-19 was fired from
China’s Korla Missile Test Complex and successfully intercepted a CSS-X-11
medium-range ballistic missile launched from the Shuangchengzi Space and
Missile Center.
The two missiles were tracked by U.S. missile warning satellites to an
intercept point at an altitude of about 155 miles in space.
Until then, the SC-19 had been used previously to boost China’s first
successful direct-ascent anti-satellite intercept on Jan. 11, 2007, when a
missile rammed into China’s FY-1C weather satellite.
“Previous SC-19 DA-ASAT flight-tests were conducted in 2005 and 2006,” the
2010 cable said. “This test is assessed to have furthered both Chinese
ASAT and ballistic missile defense [BMD] technologies.”
The cable contained a U.S. protest note to China on the 2010 test seeking an
explanation for Chinese officials about the purpose of the test and “what
steps were taken to minimize the creation of orbital debris.”
The cable said that since the 2007 ASAT test, the United States had urged
China not to conduct further space weapons tests.
An earlier cable revealed that U.S. intelligence agencies had advance word
of the 2010 space weapons test, and noted that China was not expected to
provide notification in advance of the test, which proved accurate.
Other State Department cables revealed conflicting statements from Chinese
officials on whether China planned to conduct future ASAT tests. Chinese
Foreign Ministry official He Yafei unequivocally stated to U.S. officials in
June 2008 that China would not conduct future ASAT tests. In July, China Lt
. Gen. Zhang Qinsheng said there were no plans for an ASAT test in the near
future.
