Model UN Background Guide

Committee: Disarmament and International Security Committee (DISEC/GA1)

Topic: Hypersonic Missile Regulation

Conference Year: 2025

Topic Background

Hypersonic missiles—defined as weapons capable of traveling at speeds greater than Mach 5 while maintaining maneuverability—represent a significant evolution in missile technology. Unlike traditional ballistic missiles, hypersonic missiles can evade current missile defense systems due to their speed, low altitude flight paths, and unpredictable trajectories. These capabilities pose new strategic and security challenges, prompting concerns about a destabilizing arms race and increased risks of miscalculation or accidental conflict.

The development of hypersonic weapons has accelerated rapidly over the past decade, with key military powers such as the United States, Russia, and China publicly testing and deploying various systems. Russia’s Avangard and Kinzhal missiles and China’s DF-17 hypersonic glide vehicle have demonstrated the operational maturity of these technologies. The United States has also invested heavily in hypersonic research and development, aiming to maintain strategic parity.

This topic has gained urgency due to the absence of international norms or treaties specifically addressing hypersonic weapons. Unlike nuclear arms or ballistic missiles, hypersonic missiles currently fall outside the scope of most arms control agreements. This regulatory gap risks exacerbating tensions among major powers and complicates global strategic stability. DISEC’s agenda now includes hypersonic missile regulation to explore frameworks that could mitigate risks, promote transparency, and prevent destabilizing arms races.

Key Actors

• United States: A leading developer of hypersonic technology, the U.S. seeks to maintain strategic superiority while advocating for transparency measures and confidence-building mechanisms. It is cautious about binding restrictions that could hinder its technological edge but supports dialogue on risk reduction.

• Russia: One of the first countries to operationalize hypersonic weapons, Russia emphasizes the strategic deterrence value of these systems. It often frames its hypersonic arsenal as a response to NATO missile defense deployments and is skeptical of agreements that might limit its capabilities.

• China: Rapidly advancing its hypersonic programs, China views these weapons as critical to countering U.S. regional dominance, especially in the Indo-Pacific. Beijing favors multilateral discussions but is wary of agreements that could constrain its military modernization.

• European Union (EU): The EU, particularly through the European External Action Service (EEAS), promotes arms control and non-proliferation norms. While not a hypersonic developer, the EU is concerned about regional security implications and advocates for transparency and confidence-building.

• India: Developing hypersonic technology as part of its strategic modernization, India supports balanced arms control measures that do not undermine its national security. It calls for inclusive negotiations involving all major stakeholders.

• International Organizations:

  • United Nations Office for Disarmament Affairs (UNODA): Facilitates dialogue on emerging weapons technologies and supports norm-building efforts.
  • Conference on Disarmament (CD): Though currently stalled on many issues, the CD remains a forum for arms control negotiations.
  • Missile Technology Control Regime (MTCR): A voluntary export control regime that indirectly influences hypersonic missile proliferation through technology transfer restrictions.

Bloc Positions

• Western Bloc (U.S., NATO members, Japan, Australia):
  This bloc emphasizes maintaining technological edge while promoting transparency and confidence-building measures to reduce risks of accidental conflict. They generally resist binding limitations that could hinder their strategic capabilities but support dialogue on norms and verification mechanisms.

• Russia-China Bloc:
  Russia and China advocate for recognition of hypersonic weapons as legitimate deterrents and emphasize their right to develop these technologies. They are skeptical of restrictive treaties, viewing them as potential tools of Western dominance. Both call for multilateral discussions but prioritize strategic autonomy.

• Non-Aligned and Developing States (India, Brazil, South Africa, ASEAN countries):
  This diverse group supports arms control efforts that are equitable and inclusive. They stress the importance of preventing proliferation to unstable regions and encourage transparency measures. Many advocate for a cautious approach that balances disarmament goals with national security needs.

• European Union and Like-minded States:
  The EU and partners push for comprehensive international frameworks addressing hypersonic weapons, including export controls, verification regimes, and risk reduction. They focus on preventing destabilizing arms races and promoting peaceful uses of space and missile technology.

Past UN Action

To date, the United Nations has not adopted resolutions specifically regulating hypersonic missiles; however, related actions provide relevant context:

• Resolution 70/56 (2015): Addresses conventional arms control and the prevention of an arms race in outer space, laying groundwork for discussions on emerging missile technologies.
• Resolution 74/32 (2019): Calls for transparency and confidence-building measures in outer space activities, relevant given hypersonic glide vehicles’ use of near-space trajectories.
• Reports by the UN Secretary-General on conventional arms control: Periodically highlight the risks posed by emerging weapons technologies, including hypersonic systems, and encourage member states to engage in dialogue.

While no binding agreements exist, these documents underscore the UN’s recognition of the destabilizing potential of new missile technologies and the need for international cooperation.

Questions a Resolution Should Answer

1. What definitions and classifications should be adopted for hypersonic missiles and related delivery systems to ensure clarity and avoid ambiguity?
2. How can transparency and confidence-building measures be effectively implemented to reduce risks of miscalculation and accidental escalation involving hypersonic weapons?
3. Should there be limits or bans on the testing, deployment, or proliferation of hypersonic missile systems, and if so, what mechanisms would enforce compliance?
4. How can verification regimes be designed to monitor hypersonic missile development and deployment, considering their speed and maneuverability?
5. What role should export controls and technology transfer restrictions play in preventing the spread of hypersonic missile capabilities?
6. How can dialogue and cooperation be fostered among major powers and other states to prevent an arms race and promote strategic stability?
7. What measures can be taken to ensure that hypersonic missile regulation frameworks are inclusive of developing countries and respect their security concerns?

Further Reading

• UN Documents: Official General Assembly and Security Council resolutions on arms control, Secretary-General reports on conventional weapons and disarmament, and documents from the UN Office for Disarmament Affairs provide foundational understanding of international norms and ongoing discussions. These sources offer insight into the UN’s evolving stance on emerging weapons technologies.

• Think-Tank Reports: Research papers and policy briefs from institutions such as the Stockholm International Peace Research Institute (SIPRI), the Center for Strategic and International Studies (CSIS), and the RAND Corporation analyze the technical capabilities, strategic implications, and policy options related to hypersonic missiles. These reports are valuable for understanding state motivations and potential regulatory frameworks.

• News Outlets and Expert Analyses: Reputable international media such as Reuters, BBC, and Defense News, along with expert commentary from defense analysts, provide up-to-date coverage of hypersonic missile tests, military developments, and diplomatic efforts. These sources help track the real-time evolution of the issue and public discourse.

This background guide is intended to assist delegates in developing informed positions and crafting comprehensive resolutions addressing the complex challenges posed by hypersonic missile technology.
