Introduction
United States President Bush unilaterally told the Russian President
Putin secession from the Anti-Ballistic Missile (ABM)
treaty last December, and the ABM treaty lost the effect on

The ABM treaty was concluded in 1972 between only two countries, the

However in 1983, President Reagan came announced the Strategic Defense Initiative (SDI) to start development of new missile defense plan. It was an epoch-making idea aimed at the future advanced technology for deploying various sensors, lasers, and beam weapons to space. It was called "The Star Wars program" to intercept and destroy a ballistic missile in all stages from right after its launching until flying over space and reentry to the earth. The SDI was assumed to be a program for research and concept study only, not for actual development and deployment. So that, the SDI was advanced with the interpretation that it does not violate the ABM treaty. However, the SDI program was terminated because of historical background such as the collapse of Cold War, the decrease of major threats and the reduction of defense budget.
After the end of Cold War, the concern about the proliferation of
WMD and ballistic missiles as a means of its transportation came true in the
Gulf War in 1990, when the patriot SAMs were employed
for emergency use to intercept the SCUD missile attack by Iraq. Originally, the
ABM treaty was the one to restrict the development, test, and deployment of the
ABM system, which was meant to intercept and destroy the ICBM nuclear warhead
of the 5500km or more range. The ABM treaty was not to limit the development,
test and deployment of the defense system against the Theater Ballistic Missile
(TBM) in the middle and short distances. Therefore, the
On the other hand, the development and deployment of
(3) Ballistic Missile Defense
The main objective of the U.S. withdrawal from the ABM treaty is to
get rid of the MAD mutual destruction strategy that was a legacy of the Cold
War era, and the U.S. and Russia should corporate to improve the missile
defense capability rather than the attack capability, and to advance a further
strategic arms reduction for the security of the world. In May 2002 at the Moscow summit, the
U.S. and Russia signed the Strategic Offensive Reductions Treaty (The Moscow
Treaty), which would reduce the strategic nuclear warhead of the two countries
to 1,700−2,200, about 1/3
respectively by the end of 2012. At the same time, the
The TMD and NMD systems have been distinguished for flight range and
altitude difference to deal with TBM and ICBM. In each stage of boost phase → midcourse phase → terminal phase, to detect, identify,
track, intercept, and destroy a
ballistic missile, various sensors, telecommunications, BMC4I system and
intercept weapons are required. But majority of technology research and
development, functional equipment system, and operation system are fairly
overlapped and indistinguishable for TMD and NMD. Therefore, it is said that President
Bush assumed it was possible to remove the division of TMD and NMD, and
integrate them to Ballistic Missile Defense (BMD) for more effective
development. At the same time, he assumed the missile defense system is
“International" by the deletion of word “National" from its name. It
is impossible to defend the
As the restriction of the ABM treaty was gone, the United States is
now free to research, develop, test and deploy effective BMD system,
large-scale experiment was activated and construction of new 6 ABM experiment
sites were started in Alaska. Moreover, the
(4) Use of Space and Missile Defense
Various sensors, radars, and interception weapon systems for the BMD will be deployed not only on the ground, on sea, in the air but also all possibilities of use of space. The space use so far has been limited to the detection of missile launch with IR sensor of an early-warning satellite, the tracking, the impact area and time forecast, and finally the transmission of warning information to the missile interception system. It is said that estimation accuracy is improved recently to several km and several seconds of the impact point and time, compared to several ten km and several minutes of the Gulf War days by the DSP satellites. It will be possible to have real-time warning and exact impact point estimation when the SBIRS satellites are employed in scheduled 2006.
In the future, the tracking accuracy will be much improved by the SBR (Satellite Based Radar) and layered interception and attack will be possible through all flight phases of ballistic missile: Boost phase → Midcourse phase → Terminal phase by the space deployment of ASAT (Anti Satellite: attack satellite) equipped with SBL (Satellite Based Laser; laser equipped with the satellite) beam weapon and the kinetic energy weapon. On the contrary, enemy ballistic missile side will take evasive actions including the orbit conversion, multi-warhead and evasion treatment to the missile defense. So that, it is noteworthy way to defeat enemy ballistic missile during their weakest boost and midcourse phases assuming that the evasive action will be sealed off by these interception from the space.
2. Space policy and Ramsfeld report
The United States promoted the review of space policy and space
military strategy and the reform measures steadily and strongly, based on the
report of “the Commission to Assess United States National Security Space
Management and Organization” (The Space Commission Report) in January 2001.
Recognizing that the Space capabilities are extremely important for national
security and prosperity, the
(1) Recognition of Space
The
The historical human activities expanded from the land, to the sea, and into the sky, where competition, conflict and war occurred. Reality indicates that space will be no different. Neither the means both to deter and defend against hostile actions in and from space, nor domination in space has been secured yet. The Commission concluded that the adjustment of the organization, chain of command and policies should promptly be merged to meet the national security space needs.
(2) Criteria for Space Policies
The Commission pointed out following criteria for the future of the
@Provide for national-level guidance that establishes space activity as a fundamental national interest of the United States.
ACreate a process to ensure that national-level policy guidance is carried out among and within the relevant agencies and departments.
BEnsure the government’s ability to participate effectively in shaping the domestic and international rules and policies that will govern space.
CCreate conditions that to encourage the DOD (Department of Defense) to develop and deploy systems in space to deter attack on and , if deterrence should fail, to defend U.S. Interests on earth and in space.
DCreate conditions that to encourage the Intelligence Community to develop revolutionary methods for collecting intelligence from space.
EProvide methods for resolving the inevitable issues between the defense and intelligence sectors on the priority, funding, and control of space programs.
FAccount for the increasingly important role played by the commercial and civil space sectors in the nation’s domestic and global economic and national security affairs.
GDevelop a military and civilian cadre of space professionals within DOD, the Intelligence Community and throughout government more generally.
HProvide an organizational and management structure that permits official to be agile in addressing the opportunities, risk and threats that inevitably will arise.
IEnsure that DOD and the Intelligence Community are full participants in preparing government positions for international negotiations that may affect U.S. space activities.
As stated
above, it is understood that even the
The recommendations of the Commission has
carried considerable weight because Mr. Rumsfeld, chairman
of the Commission, has become the Secretary of Defense, an important cabinet
minister of Bush Administration. The proposal points were examined immediately,
and have been embodied steadily and strongly. A year and half has passed since
the Commission reported to the Congress. There are too many projects to
enumerate such as; reviews of the doctrine, policies related to space,
strengthening of the organization in the government, promotion of the research
and development for space systems and equipments. I cannot help feeling the
degree of zeal and power of the
Moreover,
to remedy the abuses that the decision of space policies and the construction
of space systems have been conducted by unqualified people, the career
development, education and training for space professionals are to be
strengthened. It is said, "An excellent person with discernment, ability,
and experience on space activities should discuss and implement space
matter".
3. Space Threat
and Future War
(1) Threat to Space System
The space systems are always exposed and extremely vulnerable against potential threats not only of satellite system itself but also all stages from the launch process to the circular orbit, together with the ground-based facilities and instruments. The political, economic and military value of space systems makes them attractive targets for the enemy. The dangerous countries and the terrorist organizations already exist. The more increase of the world nations space activities, upgrade of advanced technology for space systems and growth of space industries proceed, the more unbalance between the advanced and late-started countries of the prosperity will expand and the competition and conflict will be more and more keen. As the space systems become more sophisticated, its vulnerability increases more and more. On the other hand, the potential threats increase their space power by using generalized space systems. An interruption or functional decrease of space systems will cause serious social confusion, and also greatly decrease operational capabilities and combat efficiency in military affairs. It is no exaggeration to say that consequence of future war will be influenced by the offense and defense space operation capabilities.
The potential enemy will disrupt or destroy our space systems by attacking the satellites in space, communications nodes on the ground and in space, or ground nodes that command the satellites before their invasion or simultaneously. The nature of threats is categorized to following 5D actions such as Disrupt (obstruction), Deception (cheat), Denial (unavailability), Degradation (function decrease) and Destroy (destruction). Our operational capabilities decrease drastically due to loss of various sensor functions, data links and satellite communication network. As a result, C4ISR function, missile early warning function and battlefield recognition abilities will be deteriorated. Moreover, due to loss or decrease of the GPS function, battlefield management and targeting ability will be so faint that the demonstrations of PGM (Precise Guided Munitions) attacks become difficult. Therefore, it makes the confusion of the land, sea and air combat power in the battlefield, and causes the delay of combat operation speed, the increase of battle damages, and makes difficult to accomplish the mission of the war.
(2) Schriever 2001
In January 2001, the U.S. Air Force Space Command (AFSPC) conducted a joint level scale war game entitled “Schriever 2001”, assuming how much future military operations depend on space assets and should counter against space threats. The game scenario was assuming that one red country, which had large-scale conventional forces and strategic nuclear force, invaded with attacks to the space system in 2007 timeframe. Examining the importance on military utility of space systems in future combat aspect, it is said that the U.S. Space Command recognized the necessity to establish the doctrine, strategy, and concept of operations for space warfare at early stage and also was aware of the incompleteness of future U.S. space power which will be built up in accordance with present force program for space. These results and the lessons learned are immediately reflected to the QDR in 2001. Continuously, it will be reflected to further consideration of national space policy and strategy, and construction of future space capabilities. War games are so important to examine future concept and force structure that the U.S. Space Command is preparing a war game of larger scale than “Schriever 2001” in 2004.
(2) Attack Mode of Threat
The following attack modes are considered as the threats to the space systems including ground-based instruments.
a.D&D (Denial and Deception)
Counterspace D&D is a highly attractive technique to disrupt enemy sensors, reconnaissance and C3I systems. It is categorized as direct and indirect. Most countries employ indirect D&D during peacetime or before hostilities. However, for increasing availability of information, Direct D&D will be used by simplified method.
b. GSAS (Ground Station Attack/Sabotage)
GSAS is a physical attack/sabotage against the ground infrastructure facilities. Variety of potential targets will be in danger for variety of attack methods. Special Forces or Guerrilla-Commando will conduct destruction attack using conventional weapons just before hostilities.
c. EA (Electronic Attack)
EA is the electronic countermeasures to the satellite system by jamming of communication equipment, links, or ground facilities. Though downlink jamming is possible with very low power and low cost, uplink jamming is extremely tough to achieve global effect. Regarding the increasing military use of commercial communication satellite, it is recognized defenseless and all satellite communications systems are susceptible. Though all satellite systems become potential targets, EA influence is only effective while EA system is operating, and not enduring.
GPS jammer made in
d. ASAT (Anti Satellite)
ASAT is categorized into interceptor weapons and direct energy weapons. Variety of ammunitions and various methods are being researched and developed. As interceptor weapons attacks, there is kinetic energy attack by hitting the enemy satellite directly to destroy, and micro-satellite or nano-satellite group attack by flying alongside the enemy satellite until commanded to disrupt, disable or destroy. As direct energy weapons attack, there is laser weapon attack by irradiating laser beam to the enemy satellite from ground, aircraft, or spaceship to destroy or deteriorate its function. Nuclear explosion in the space will destroy nearby satellites and shorten lifetime of satellites in the line of sight, by nuclear detonation.
It is indispensable for ASAT attack to have sophisticated technology to identify, track or intercept enemy satellites. Though countries, which can become a potential threat of ASAT attack are limited now, technology applicable to ASAT weapons has been proliferating. The strategic threshold of ASAT attack is fairly high, but it is necessary to keep alertness for ASAT attack just before or immediately after of the enemy invasion.
e. Cyber Threat
The military C4ISR systems are extremely dependent on space system including ground facilities. Cyber Threats would invade into the computer system or network of C4ISR system, using hackers to decrease enemy operation and combat capabilities by means of deception, exploitation, and destruction. It is recognized as a threat with the highest probability from peacetime to wartime.
4. Details and Directions of Military Use of
Space
(1) Details of Space Military Use
The development of space activities has progressed as a part of
military technology, so that space and military affairs are originally in close
relationship. The
In the state of recent war since the Gulf War, the space military use technology that is closely linked with the RMA (military technological revolution) technologies became an extremely important requisite for the aspect of the strategy and transformation of the military. Various sensors of reconnaissance and early warning satellites enable the high-quality military intelligence, and the GPS satellites contribute to accurate battlefield recognition, targeting and all weather PGM strike. The C4ISR network and data-links of the communications satellite enable to relay necessary information from sensor to shooter in real time. Those brought epoch-making revolution for accomplishment of military operations. Of course, it has synergy effect by integration with the weapon systems of AWACS, JSTRS or UAV in the air and other systems on the ground, and military use of space system became indispensable for modernizing and strengthening the combat or war operation capabilities of Army, Navy, and Air Force.
Though the Gulf War is some time called as the first Space War in human race, it dose not deserve to be called so. Because there were no obstruction or attack to the space system either into space, or on the earth, and nothing of attack from space too. The space system itself was under early developmental stage that existed on orbit around the earth, and the military use technology is not yet fully developed or experienced. In fact, in only eight years between the Gulf War and the Kosovo War, the accuracy of missile warning and timing have been improved so rapidly from several minutes to several seconds for after-launch missile warning, and several 10km to several km for estimation of impact point. The space technology and application technology have drastically pushed ahead the accuracy, the speed, capacity, and range of activities. By the release of military space technologies, the civil and commercial space systems have been developed and advanced remarkably in variation and application. On the other hand, the dependence of the military on the commercial space system is also common. It can be said that present state of military use of space is still in early stage and has just started, seen from the future’s fully developed space technology.
(2) Transitional Military Use of Space
Considering the intensity of military space use, and state of space
activities, it can be divided into the following three stages. And now, the
In the first stage, the construction of space systems and space
utilization activities are promoted under narrow sense of peaceful use of
space. It preserves space sanctuary based on ideal concept that never allows
bringing military affairs in space and securing a freedom of the space use.
Among the least developed countries, there are a lot of countries that declare
the same standpoint strategically in principle. The Diet resolution of
In the second stage, the nation develops and utilizes the military
purpose space system for the “Force Enhancement” mission to increase the war
accomplishment abilities and the combat capabilities of the Army, Navy and Air
Forces on the earth. Yet, restraining from military deployment and activities
in space, the nation conducts the “Space Control” mission to observe, identify
and manage all artificial things in space, and then to secure the freedom of
military space use. At present, the
world including the
In the third stage, anticipating that the threats related to space become a reality, the concept of the “Force Application” mission will take place. This concept is an attempt of power projection into space as well as air, land and sea operations to deter or defend against potential threats attack in space. It has not been internationally acknowledged yet, to enable power projection or military demonstration in space, from space, through space and to refuse the enemy freedom of space use at the same time.
The
(3) Reshape of International Space Law
The
Space activities have been governed by treaties and by international
and domestic laws and regulations. Though appreciating its achievement so far,
it is advocated that the legal and regulatory framework should be adjusted to
the new space age with expansion of space system development and space
activities. Especially, it is forecasted that the allies will be requested to
agree with this law shaping to enable power projection to space and
military campaign in space under the initiative of the
As to the criticism of contradiction to "Peaceful use of
space" principle, the
Every country has the right to defend the benefit and national
interest in space and from space. The international customary law admits the
routine military activities in outer space as well as on the international
waters and in the international airspace. There are no articles anywhere in
international law prohibiting the existence of military power and activities in
space. However, the
After word
The withdrawal from the ABM treaty by President Bush is considered
as a step for the initiative to take lead in new space order, which enables
power projection and military campaign in space, as an important transition of
the
Though present state on the military use of space is still in its
early stage, the development of space capability and the importance of space
mission are rapidly increasing. The “Space Superiority” that secure the freedom
of friendly space activities and refuse enemy freedom will become a top
priority not only for military operation but also for national strategy in the
near future. The world is advanced to the time of "The nation who controls
space controls the world". It is time seriously to examine and consider
the space policy or strategy of
