An Indian Navy warship, INS Kolkata, collided with a Pakistan Navy vessel, PNS Hunain, in the North Arabian Sea on September 15.
India alleged that PNS Hunain executed a dangerous overtaking maneuver at high speed, leading to the collision.
India summoned Pakistan’s Charge d’Affaires and lodged a strong protest, citing violations of Article 10 of the 1991 India-Pakistan agreement.
INS Kolkata sustained no major damage and remained at sea, while PNS Hunain was damaged and returned to harbor.
Pakistan rejected India's allegations, presenting a different account of the incident.
Detailed Insights:
The collision occurred in international waters, approximately 120 nautical miles from the Gulf of Oman.
INS Kolkata is the lead ship of India's Project 15A Kolkata-class guided-missile destroyers, commissioned in August 2014.
It has a displacement of about 7,400 tonnes and is equipped with BrahMos supersonic cruise missiles for anti-surface strike.
PNS Hunain (F-273) is an offshore patrol vessel, the first of Pakistan's larger OPV 2600-based vessels, commissioned in July 2024.
It has a displacement of about 2,600 tonnes and is designed for maritime security, surveillance, and combat operations.
Article 10 of the Agreement between India and Pakistan on Advance Notice on Military Exercises, Manoeuvres and Troop Movements, 1991, mandates naval vessels to maintain a separation of three nautical miles (approximately 5.6 km) in international waters.
This bilateral agreement is a Confidence-Building Measure (CBM) aimed at reducing the risk of miscalculation and accidental escalation between the two nuclear-armed nations.
A similar incident occurred in June 2011 when PNS Babur and INS Godavari came close during anti-piracy operations in the Gulf of Aden.
India has instructed its Charge d'Affaires in Islamabad to raise the matter with Pakistan’s Foreign Ministry, emphasizing compliance with bilateral agreements.
Key Concepts Involved:
Charge d'Affaires: A diplomat who heads a diplomatic mission in the absence of an ambassador or in a country where the sending state does not maintain an ambassador-level relationship.
Confidence-Building Measures (CBMs): Arrangements or actions taken by states to reduce mistrust, improve transparency, and manage the risk of conflict, especially regarding military capabilities and intentions.
International Regulations for Preventing Collisions at Sea (COLREGs): International rules published by the International Maritime Organization (IMO) that set out navigation rules to be followed by vessels at sea to prevent collisions.
