Article1: Maritime Law in Warfare
Why in News: The sinking of the Iranian warship IRIS Dena by a US submarine near Sri Lanka’s Exclusive Economic Zone amid the expanding West Asia conflict has triggered debate on the legal framework governing maritime warfare.
Key Details
- An Iranian naval frigate IRIS Dena was reportedly sunk by a US submarine torpedo attack near Sri Lanka’s Exclusive Economic Zone (EEZ) while returning from a multinational naval exercise in India.
- The incident has expanded the US–Israel–Iran conflict beyond West Asia, raising security concerns in the Indian Ocean Region (IOR).
- The event has sparked discussion about the legality of attacking warships in international waters under international maritime law.
- It highlights the role of UNCLOS, the UN Charter, and the law of naval warfare in regulating maritime conflict.
International Maritime Law Framework
- United Nations Convention on the Law of the Sea (UNCLOS): UNCLOS (1982) provides the legal framework governing oceans, maritime boundaries, and navigation rights. It defines zones such as territorial seas (12 nautical miles), contiguous zones, and Exclusive Economic Zones (200 nautical miles).
- Jurisdiction in Different Maritime Zones: Coastal states have full sovereignty in territorial waters, limited regulatory authority in the contiguous zone, and resource rights in the EEZ. However, international waters beyond these zones remain largely open to all states.
- Limitations of UNCLOS in Warfare: UNCLOS mainly regulates peacetime maritime governance and does not comprehensively regulate armed conflict at sea. During wartime, it operates alongside the law of naval warfare.
- Status of the United States: Although the United States has not formally ratified UNCLOS, it generally follows many of its provisions as customary international law.
Law of Naval Warfare
- Legitimate Military Targets: Under the law of armed conflict at sea, enemy warships are considered legitimate military targets during armed conflict, regardless of their location in international waters.
- Principles of Distinction and Proportionality: Naval warfare must follow humanitarian law principles—attacks should target military objectives and avoid excessive civilian harm.
- Historical Precedents: Submarine attacks on warships have occurred historically, such as the sinking of INS Khukri during the 1971 India–Pakistan War and ARA General Belgrano during the 1982 Falklands War.
- Role of Naval Blockades and Maritime Strategy: Control over sea routes and naval dominance remain central elements of warfare, influencing trade routes and strategic security.
Role of the UN Charter in Use of Force
- Article 2(4) – Prohibition on Use of Force: The UN Charter prohibits the threat or use of force against the territorial integrity or political independence of any state.
- Article 51 – Right to Self-Defence: States retain the inherent right to individual or collective self-defence if an armed attack occurs.
- UN Security Council Authorisation: Military action may also be legally justified if authorised by the UN Security Council under Chapter VII.
- Challenges in Enforcement: Geopolitical rivalries and veto powers of permanent members often limit the Council’s ability to authorise or regulate such actions.
Strategic Importance of the Indian Ocean Region
- Critical Global Trade Route: The Indian Ocean carries nearly 80% of global maritime oil trade and a significant share of international commerce.
- India’s Maritime Security Interests: India maintains a strong naval presence to safeguard sea lanes, protect trade routes, and ensure stability in the region.
- Regional Security Concerns: Any escalation of external conflicts into the Indian Ocean Region can threaten shipping routes and regional stability.
- Multilateral Naval Cooperation: Exercises like MILAN and International Fleet Reviews aim to promote maritime cooperation, interoperability, and regional peace.
Technological and Strategic Aspects of Naval Warfare
- Submarine Warfare Capabilities: Modern submarines equipped with advanced torpedoes such as the Mark-48 heavyweight torpedo are capable of targeting large naval vessels.
- Stealth and Surprise Advantage: Submarines remain one of the most effective naval assets because of their stealth and underwater strike capability.
- Impact of Technological Warfare: Advances in sonar systems, torpedoes, and missile technology have significantly changed maritime combat dynamics.
- Rare Nature of Torpedo Attacks Today: Since World War II, submarine torpedo strikes against major warships have been relatively rare, making such incidents strategically significant.
Implications for India
- Security in the Indian Ocean Region: Expansion of external conflicts into the region could increase military tensions and maritime surveillance needs.
- Diplomatic and Strategic Balancing: India must maintain balanced relations with major powers while protecting its strategic interests.
- Strengthening Maritime Domain Awareness: Enhanced monitoring of sea lanes, intelligence sharing, and naval preparedness are crucial.
- Promoting Rules-Based Maritime Order: India supports adherence to international law and freedom of navigation, particularly in the Indo-Pacific.
Conclusion
The evolving nature of maritime conflict highlights the need for stronger adherence to international law and cooperative security mechanisms. Strengthening global maritime governance, promoting transparency in naval operations, and enhancing regional cooperation are essential to prevent escalation. For India, safeguarding the stability of the Indian Ocean Region while upholding a rules-based maritime order will remain a strategic priority.
