Model UN Background Guide

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

Topic: Hypersonic Missile Regulation

Conference Year: 2026

Topic Background

Hypersonic missiles, capable of traveling at speeds exceeding Mach 5 and maneuvering unpredictably during flight, represent a significant evolution in missile technology. Unlike traditional ballistic or cruise missiles, hypersonic weapons combine extreme velocity with maneuverability and low-altitude flight paths, making them difficult to detect and intercept. This technological leap has profound implications for global strategic stability and arms control frameworks.

The development of hypersonic missiles dates back to early research programs in the late 20th century, but their operational deployment has accelerated rapidly in the 2010s and early 2020s. Major military powers including the United States, Russia, and China have publicly tested and, in some cases, deployed hypersonic systems. These weapons blur the lines between nuclear and conventional deterrence due to their speed and potential to carry various payloads. The strategic ambiguity surrounding their use increases risks of miscalculation and escalation in times of crisis.

Hypersonic missile regulation has emerged as a critical topic on DISEC’s agenda due to the growing proliferation of these weapons and the absence of comprehensive international agreements addressing their development, testing, and deployment. Unlike nuclear weapons or traditional ballistic missiles, hypersonic weapons currently fall into a regulatory gap, with existing treaties such as the Missile Technology Control Regime (MTCR) providing limited coverage. The rapid pace of technological advancement and increasing geopolitical tensions have made international dialogue on hypersonic arms control urgent.

In 2025, a series of high-profile hypersonic missile tests by multiple states, coupled with growing concerns about their destabilizing potential, prompted renewed calls within the United Nations to address the issue. The security community recognizes that without early multilateral frameworks, the hypersonic arms race could undermine decades of arms control progress and exacerbate global insecurity.

Key Actors

United States: A leading developer of hypersonic technology, the U.S. views these weapons as crucial to maintaining strategic superiority, particularly in countering near-peer adversaries. Washington supports arms control but stresses the need for verifiable and enforceable measures that do not hinder its technological edge.

Russia: Among the first to publicly announce operational hypersonic missiles, Russia emphasizes the defensive nature of its programs and frames hypersonic weapons as deterrents against NATO expansion. Moscow advocates for international agreements but insists on parity and recognition of its security concerns.

China: Rapidly advancing hypersonic capabilities, China prioritizes these systems in its military modernization efforts. Beijing calls for multilateral dialogue but is cautious about restrictions that could limit its strategic options, especially given its perception of U.S. containment policies.

European Union (EU): The EU, particularly through the European External Action Service (EEAS), promotes arms control and risk reduction measures. While no EU member state currently fields hypersonic missiles, the bloc is concerned about regional security implications and supports transparency initiatives.

India: Developing indigenous hypersonic technologies, India views these weapons as vital to its strategic deterrence, especially vis-à-vis China and Pakistan. New Delhi advocates for balanced arms control frameworks that consider regional security dynamics.

International Atomic Energy Agency (IAEA): While primarily focused on nuclear materials, the IAEA’s role in verifying nuclear payloads on delivery systems makes it a potential stakeholder in hypersonic missile regulation, particularly regarding dual-capable systems.

United Nations Office for Disarmament Affairs (UNODA): Facilitates dialogue and capacity-building on emerging weapons technologies, including hypersonic missiles. UNODA supports establishing norms and transparency measures to prevent destabilization.

Bloc Positions

Western Bloc (United States, Canada, NATO members, Japan, Australia)

• Support the development of hypersonic weapons as a deterrent but acknowledge the risks of an unchecked arms race.
• Advocate for multilateral arms control agreements emphasizing verification, transparency, and risk reduction.
• Emphasize the need to prevent proliferation to non-state actors and destabilizing deployments near conflict zones.

Russian-Chinese Bloc

• Stress the strategic necessity of hypersonic weapons for national security and deterrence.
• Support arms control in principle but demand parity and recognition of their security concerns.
• Oppose overly restrictive measures that would limit their sovereign right to develop advanced weapons.
• Call for inclusion of all major powers in negotiations to ensure fairness.

Non-Aligned and Developing States (India, Brazil, South Africa, ASEAN countries)

• Generally cautious about hypersonic weapons, emphasizing their potential to exacerbate global insecurity.
• Advocate for international dialogue and transparency but wary of agreements that may entrench existing power imbalances.
• Stress the importance of peaceful uses of missile technology and non-proliferation.

European Union and Associated States

• Promote arms control, confidence-building measures, and risk reduction to prevent accidental escalation.
• Support transparency and data-sharing initiatives.
• Emphasize the humanitarian and security risks posed by hypersonic weapons.

Past UN Action

While the United Nations has not yet passed resolutions specifically regulating hypersonic missiles, several related actions provide a foundation for discussion:

• UNGA Resolution 70/33 (2015) on “Reducing Nuclear Danger” highlights the risks posed by emerging weapons technologies and calls for international dialogue on strategic stability.
• UNSC Presidential Statement S/PRST/2023/4 emphasized the need to address new military technologies, including hypersonic weapons, in the context of international peace and security.
• Reports by the UN Secretary-General (e.g., A/76/127) have underscored the challenges posed by hypersonic weapons to existing arms control regimes and recommended enhanced transparency and confidence-building measures.
• The Missile Technology Control Regime (MTCR), while not a UN body, has updated guidelines to partially address hypersonic missile technology transfer, although these remain voluntary and non-binding.

Questions a Resolution Should Answer

1. What specific definitions and technical parameters should be used to categorize hypersonic missiles within international law?
2. How can verification and monitoring mechanisms be designed to effectively track hypersonic missile development and deployment?
3. What confidence-building measures can be implemented to reduce the risks of accidental or unintended use of hypersonic weapons?
4. How should the international community address the dual-use nature of hypersonic technologies that have civilian applications?
5. What measures can be taken to prevent the proliferation of hypersonic missile technology to non-state actors or unstable regions?
6. How can arms control agreements on hypersonic missiles be integrated with existing treaties such as the MTCR and New START?
7. What role should international organizations, including UNODA and the IAEA, play in supporting regulation and transparency?
