Characterizing the “Space Weaponization Debate” Pro Arguments l l Just as other environments are used for offensive military purposes, so will the environment of space be used Emerging threats to our national interests and assured access to space require we develop and maintain capabilities to protect our space assets The U. S. economy and way of life depend on space systems The space weaponization debate is a red-herring. Space was weaponized long ago by the transit of ballistic missiles Con Arguments l Space should remain a sanctuary for peaceful scientific uses l Space weaponization is: Not inevitable and international agreements barring weaponization are possible and desirable l Pre-mature and the sanctuary status of space is in the interests of the United States Use of space weapons would create harmful orbital debris There is no conceivable scenario in which space weapons provide a benefit greater than their harm 3 l l l 04 -20 -05

National Space Policy (1996) The United States is committed to the exploration and use of outer space by all nations for peaceful purposes and for the benefit of all humanity. "Peaceful purposes" allow defense and intelligencerelated activities in pursuit of national security and other goals. The United States rejects any claims to sovereignty by any nation over outer space or celestial bodies, or any portion thereof, and rejects any limitations on the fundamental right of sovereign nations to acquire data from space. The United States considers the space systems of any nation to be national property with the right of passage through and operations in space without interference. Purposeful interference with space systems shall be viewed as an infringement on sovereign rights. 5 04 -20 -05
National Space Policy (1996) (Cont. ) National security space activities shall contribute to U. S. national security by: (a) providing support for the United States' inherent right of self-defense and our defense commitments to allies and friends; (b) deterring, warning, and if necessary, defending against enemy attack; (c) assuring that hostile forces cannot prevent our own use of space; (d) countering, if necessary, space systems and services used for hostile purposes; (e) enhancing operations of U. S. and allied forces; (f) ensuring our ability to conduct military and intelligence space-related activities; (g) satisfying military and intelligence requirements during peace and crisis as well as through all levels of conflict; (h) supporting the activities of national policy makers, the intelligence community, the National Command Authorities, combatant commanders and the military services, other federal officials, and continuity of government operations. 6 04 -20 -05

Space Force Application • Currently no weapons in Space • Do. D Space Policy (1999) tasks US military to plan for Force Application from space • International law & treaties prohibit weapons of mass destruction in space • “Conventional” weapons are not prohibited Apply Force From Space 17 04 -20 -05
Space Force Application: Influencing the Terrestrial Battlespace l l Defined as: l “…things intended to cause harm that are based in space or that have an essential element based in space. The degree of harm…may range from temporary disruption to permanent destruction or death. ”* Generic alternatives: l Space-based directed-energy and kinetic-energy weapons against missile targets l Kinetic-energy weapons against ground targets l Conventional weapons against ground targets 18 *Preston, et. al. , Space Weapons Earth Wars, RAND, 2002, p. 23. 04 -20 -05

S. l Space Control and Force Application missions l Decision-making rationale and factors for space weapons acquisition by U. S. and/or others l Policy choices and conclusions 20 04 -20 -05
Emergence of Space Competitors? l l Currently, no peer in space to threaten U. S. national interests However, concern for developments in: l China l l l Russia: long-standing interests and capabilities l Nuclear proliferation and weapons delivery programs in North Korea, Iran, Libya, Pakistan l Continued transfer of ballistic missile-related technology by Russia and China Bottom line: l Technically challenging but doable l Legal constraints on WMD do not prohibit space weapons l Countermeasures are possible – asymmetric strategies by competitors, allowing competition without having to become space -faring nations 21 04 -20 -05 l l Human spaceflight Navigation, communications, remote sensing, weather, oceanography, microgravity, science and astronomy, and microsatellites KE ASAT, jammers, “parasite” satellites, ground-based lasers
Concern for Vulnerability of U. S. Space-Based Assets “If U. S. is to avoid a “Space Pearl Harbor” it needs to take seriously the possibility of an attack on U. S. space systems”* l What might be a “Space Pearl Harbor”? l Lethal actions, such as: l l Debilitating/destroying attack on U. S. and allied space assets through electromagnetic pulse (EMP) event staged by hostile forces in orbit Non-lethal actions (i. e. , for a limited period of time, for specific objectives) l Jamming, spoofing, blinding *Report of the Commission to Assess United States National Security Space Management and Organization (January 2001) 22 04 -20 -05
If the U. S. Were to Acquire Space Weapons, How Might It Happen? l l Under what circumstances might the U. S. decide to acquire? l Deliberately l Incidentally Once the decision is made, how might the transition occur? l Possible strategies l Possible consequences 23 04 -20 -05
Possible Circumstances Requiring Purposeful Decision-Making l Responding to threat(s) by undeterred adversaries l Responding to another nation’s decision to acquire, whether adversaries or allies l With another nation(s), to forestall, control, or influence their independent acquisition of space weapons l Unilaterally, in absence of compelling threat, to demonstrate global leadership, protect U. S. and allied economic investments, improve efficiency and effectiveness of military capabilities, etc. 24 04 -20 -05
Possible Circumstances Involving Incidental Decision-Making l Commercial or civil development of technologies with applicability to military purposes l Incremental decision – hedging strategy as way to shape security environment l Monolithic decision and implementation – reactive strategy to deal with emerging threat that may be defensive and stabilizing in nature 25 04 -20 -05
Transition Period (1) l l l Ideally, no consequences for U. S. deployment Worst case: l Adversaries take lethal action to deny U. S. ability to launch and deploy first space weapon Adversary’s options are numerous l Deterrent capability, possibly nuclear, leading to possible launch on warning/launch under attack policy l Physical attack – on launch sites l Burying targets l Developing/deploying “silver bullets, ” such as ASATs l “Seize moral high ground against U. S. hegemony” 26 04 -20 -05
Transition Period (2) l l Responses by allies l Potential political pressure l Potential fallout in other non-space-related areas (e. g. , foreign policy issue of great importance to U. S. interests) l Adversary attempt at coercive behavior to influence ally l Commercial companies’ reaction to possible orbital debris that, depending on orbits, may last forever World may view U. S. acquisition and deployment decision as risky behavior, with long term consequences for U. S. global leadership 27 04 -20 -05
Policy Context for Deciding to Acquire and Deploy Space-Based Weapons • From a narrow, operational viewpoint: – Technical feasibility – Strategic desirability – Cost l l • However, other sensitivities: – Political will – Legal restrictions and ramifications – Reactions of allies, neutrals, and adversaries Some sensitivities have underpinning them the notion of space as a sanctuary: l U. S. has most to lose because of dependence on space assets l Absence of imminent threats to U. S. freedom of space could lead to perceptions of U. S. aggressive behavior l Potentially trigger arms race in space Others argue that U. S. inhibitions against space weapons deployment do not necessarily apply to others 28 04 -20 -05 l U. S. needs to press ahead with development and deployment
What If Others Decide to Acquire Space Weapons? l l Range of “others” l Peer competitors l U. S. friends and allies l Non-peer competitors l Neither friend nor foe l Non-state coalition of entities (possibly state-assisted) Decisions will be driven by national interests l Security, e. g. : l l Regional threats requiring long-range force projection Overcoming competitor’s military strengths Economic and technological Political: l l National prestige, peer recognition Global reach and power projection Enhanced freedom to act regionally/globally Promotion of internal security 29 04 -20 -05
Agenda l Characterizing the “space weaponization” debate l National space policy and the importance of space to the U. S. l Space Control and Force Application missions l Decision-making rationale and factors for space weapons acquisition by U. S. and/or others l Policy choices and conclusions 30 04 -20 -05
Policy Choices Facing the United States l Continue to maintain consistency in long-held spacerelated principles, yet be prepared to acquire and deploy space-based weapons should circumstances change l Move now, through explicit policy, programmatic, and budgetary decisions, to deploy space-based weapons based on national interests and emerging threats l Prepare for the inevitable: pursue a deliberate, long-term hedging strategy 31 04 -20 -05
Impact of Security Challenges Facing U. S. Defense Planning in 2006 QDR Higher VULNERABILITY Irregular Catastrophic q Unconventional methods adopted and employed by non-state and state actors to counter stronger state opponents. (Erode our power) Lower q Acquisition, possession, and possible employment of WMD or methods producing WMD-like effects against vulnerable, highprofile targets by terrorists and rogue states. (Paralyze our power) Traditional Disruptive q States employing legacy and advanced military capabilities and recognizable military forces, in long-established, wellknown forms of military competition and conflict. (Challenge our power) Higher q International competitors developing and possessing breakthrough technological capabilities intended to supplant U. S. advantages in particular operational domains. (Marginalize our power) Lower LIKELIHOOD Do space weapons contribute to “filling the gaps” in capabilities to respond? 32 04 -20 -05
Conclusion l Space will become yet another environment for the full spectrum of human activities, including conflict l Not a matter of should space weapons be deployed, but when l Prudent approach to protect U. S. national interests is a proactive strategy for shaping political, technological, diplomatic, and security environment 33 04 -20 -05
