TOKYO - Japan's costly ballistic missile shield, which has never been used in a
real-world situation, could soon have its first test.
As tensions mount over North Korea's plan to launch a newly developed
satellite-bearing long-range missile, Japan's Defense Minister Yasukazu Hamada
on Friday ordered the Japan Self-Defense Force (SDF) to prepare to destroy any
ballistic missile fired from North Korea if it looks like hitting the country.
North Korea has said that it is preparing to launch a rocket carrying a
communications satellite into orbit any time between April 4 and April 8 for
the peaceful use of space, highly possibly
disguising a Taepodong-2 long-range missile. These missiles can also carry
Following a National Security Council meeting with Prime Minister Taro Aso and
other cabinet members, Hamada ordered the SDF to activate Japan's missile
defense system and intercept the missile or any debris from it.
The destruction order is based on paragraph 3 of article 82-2 of the SDF Law,
which stipulates that even though the possibility of a missile or rocket
falling onto Japan is unclear, the SDF can take preventative action. The order
is Japan's first of its kind after it revised its SDF Law in 2005 and legalized
the possible shooting down of ballistic missiles and rockets should it become
likely that those would hit Japan.
"Whether [it is] a satellite or a missile test, it's very unpleasant that it
will fly over Japan and it should never have to be undergone," Hamada told
reporters in a televised news conference broadcast nationally after the
National Security Council meeting. "Whatever North Korea's intentions are, [I]
hope it to stop the launch, and it's natural for the [Japanese] government to
destruct it in case" its planned launch fails, Hamada said.
Many believe that under the pretext of a satellite launch, North Korea is
poised to test-fire a long-range ballistic missile to boost national prestige
ahead of the Supreme People's Assembly starting on April 9. This date is also
the 16th anniversary of Dear Leader Kim Jong-il's rise to chairman of the
National Defense Commission of North Korea. Pyongyang plans the launch time
from 11am to 4pm Tokyo time during the declared period.
North Korea has notified the International Maritime Organization of its pending
satellite launch, apparently to obtain international legitimacy. The North
Koreans maintain that as this is a satellite launch, they would view its
shooting down as an act of war.
A three-stage Taepodong-2?
There is widespread speculation among military experts that North Korea will
launch a third-stage version of the newly developed Taepodong-2 missile, which
has a range of up to 8,000 kilometers. Many countries, such as the United
States and South Korea, are concerned that a successful test-firing will
provide Pyongyang with the capability for inter-continental ballistic missiles
The US Director of National Intelligence, Dennis Blair, told the US Senate
Armed Services Committee on March 10 that "if a three-stage space launch
vehicle works, then that could reach not only Alaska, Hawaii, but also part of
what the Hawaiians call 'the mainland' and what the Alaskans call 'the lower
48'." Blair also said the North indeed planned a space launch as it claimed,
but the technology was indistinguishable from that of ICBMs.
In August 1998, the North fired a Taepodong-1 missile, a two-stage ballistic
missile, to put a satellite into orbit, but apparently it failed. This time,
the North is using its longest-range Taepodong-2, whose first test also ended
in failure in July 2006.
Japan's missile defense system
Based on the destruction order issued on Friday, Japan's SDF aims to destroy
any falling objects from the North Korean missile by following a two-step
process over and beyond Japanese territory.
The Japan Maritime Self Defense Force is deploying the Kongou and the Chokai
- the two Aegis-equipped ballistic missile defense (BMD) destroyers fitted with
SM-3 missiles among Japan's six Aegis-equipped destroyers - to the Sea of
Japan. One Japanese Aegis-equipped destroyer called Kirishima will also
be sent to the Pacific to detect and track the North Korean projectile's path
and to collect data on it to figure out whether it is a satellite or a missile. Kirishima
has no ability to intercept it.
The Japan Air Self-Defense Force will shift its Patriot Advanced Capability-3
(PAC-3) ground-based interceptor missiles currently deployed at the Hamamatsu
base in Shizuoka prefecture to Japan Ground Self-Defense Force bases in Akita
and Iwate prefectures in northeastern Japan, where rocket debris from a failed
launch might fall.
Japan's BMD Standard Missile-3 (SM-3) can intercept inter-continental ballistic
missiles at an altitude of about 100 kilometers and the PAC-3 has a range of
about 20 kilometers. Thus, the ground-based PAC-3 is responsible for the lower
range of the shield and is designed to intercept incoming missiles the SM-3
By convention, a country's sovereignty over airspace only extends approximately
100 kilometers above sea level, the boundary between the Earth's atmosphere and
space. North Korea's rocket could reach 1,000 km. This makes it hard for Tokyo
to claim an airspace incursion on Pyongyang's part, should the missile fly over
northern Japan above the atmosphere.
The Japan Maritime Self Defense Force has carried out two SM-3 missile
intercept tests, with mixed results. The first test-firing by the Kongou
in December 2007 was successful, but the second test from the Chokai, in
November last year, failed to strike the dummy missile. Meanwhile, Japan Air
Self-Defense Force's PAC-3 missile successfully intercepted a tactical
ballistic missile target in its first test conducted on a range in New Mexico
in the United States in September.
Japan spent 662.3 billion yen (US$6.7 billion) to deploy its ballistic missile
defense system during the fiscal years of 2004 to 2008. Out of this amount,
40.3 billion yen was spent on PAC-3.
The failure to intercept any debris from the North Korean rocket or missile
would no doubt upset many Japanese taxpayers, damaging the already unpopular
and buffeted Aso administration.
For North Korea, a failed test-firing would be an embarrassment and a lost
opportunity for the regime to rally its people with its "glorious"
accomplishments in space. No doubt, though, ordinary North Koreans will never
be made aware of any failure.
"If there is a failure, some might be executed by hanging by Kim Jong-il',"
Japanese military analyst Toshiyuki Shikata told Asia Times Online. "But in
Japan, no one will be executed by hanging, even if there is a failure. This is
a game of chicken for North Korea, not of us."
