The North Arabian Sea turned tense on September 15, 2026. A Pakistani Navy Hunain-class corvette cut across the bow of an Indian Navy warship on a routine patrol. The two hulls brushed. No one got hurt.
No steel buckled. But New Delhi summoned Pakistan’s top diplomat the next morning and lodged a formal protest. The incident happened roughly 220 kilometers east of Oman, in international waters.
I have followed India-Pakistan maritime encounters for years. This one is small on the surface. But it fits a pattern that naval watchers should understand.
What Actually Happened That Evening?
The Indian warship was on a surveillance mission. Sources say PNS Hunain shadowed it first. Indian officers issued repeated warnings over Channel 16, the standard maritime distress and safety channel.

The Pakistani vessel did not back off. It sped up. It crossed the Indian ship’s bow from the starboard side. The bow of the Pakistani corvette scraped against the Indian hull.
No structural damage. No injuries. The Indian warship continued its mission after the contact. That detail matters. If the collision had been severe, the ship would have needed repairs or escort.
The Vessel at the Center: PNS Hunain
PNS Hunain carries hull number F-273. It belongs to Pakistan’s Yarmook class. Damen Shipyards built it in Galați, Romania.
The ship displaces about 2,600 tons. It stretches 98 meters long. Top speed sits around 22 to 24 knots.
Pakistan Navy inducted Hunain in 2024. It is an offshore patrol vessel. Its job includes border surveillance, counter-piracy, anti-smuggling, and maritime security missions . It carries a 76mm main gun and two 20mm secondary guns.
This is not a front-line missile corvette. It is a patrol ship. That makes its aggressive maneuver more puzzling to analysts.
Why the Indian Navy Calls It “Unprofessional”?
Naval encounters at sea follow unwritten rules. Ships keep safe distance. They signal intentions. They avoid sudden course changes near another vessel.

Indian sources say Hunain broke all three. It approached at high speed. It did not slow down before crossing the bow. It failed to maintain distance.
One source described the move as “aggressive, intimidatory and unprofessional”. Another noted that the sea state was rough at the time, which makes close maneuvering riskier.
The Indian Ministry of External Affairs tied the conduct to a specific agreement. Article 10 of the 1991 India-Pakistan pact on advance notice of military maneuvers applies here . New Delhi says Pakistan violated it.
The Diplomatic Fallout
India summoned Pakistan’s Charge d’Affaires in New Delhi on September 16. The meeting lasted about 30 minutes . India lodged a “strong protest”.
The MEA told the Pakistani diplomat to convey a clear message. All military units must exercise due care. They must respect bilateral agreements. Such incidents must not repeat.
India’s envoy in Islamabad received instructions to lodge a similar protest with Pakistan’s Foreign Ministry.
Pakistan has not publicly responded to the protest as of this writing . That silence itself is worth noting. Islamabad typically responds to Indian claims within a day or two.
A Pattern, Not a One-Off
This is not the first time Pakistani and Indian naval vessels have tangled in the Arabian Sea. In June 2011, PNS Babur and INS Godavari had a similar close encounter. The details differ. The pattern does not.
The 2011 incident also involved a Pakistani ship maneuvering near an Indian vessel in international waters. It also led to diplomatic protests. The two navies have a history of shadowing each other in these waters.
What changed in 2026 is the ship type. Hunain is brand new. Pakistan inducted it in 2024. It represents a recent addition to Pakistan’s offshore patrol fleet. New ships often mean new crews. New crews sometimes make mistakes. Whether that explains Hunain’s conduct remains unclear.
The Indian Warship Involved
Indian sources have not named the exact vessel. They describe it only as a “frontline Indian Navy warship” . NDTV reported that both ships moved away after the contact.
The North Arabian Sea hosts several Indian Navy assets at any given time. Delhi-class destroyers patrol there regularly. INS Delhi displaces 6,700 tons and stretches 163 meters long.
If a 6,700-ton destroyer and a 2,600-ton corvette collide, the smaller ship suffers more. The fact that neither ship reported damage suggests the contact was light.
India did not release the Indian ship’s name. That is standard practice in these incidents. Naming the vessel would reveal patrol patterns.
What This Means for Regional Tensions?
India and Pakistan downgraded diplomatic ties in 2019. They have kept a fragile ceasefire since a cross-border conflict in May 2025. Naval encounters add another layer of risk.
The North Arabian Sea carries significant commercial traffic. It connects to the Gulf of Oman and the Strait of Hormuz. Oil tankers and container ships pass through these waters daily.
An isolated scrape between two warships will not disrupt shipping. But repeated incidents could raise insurance premiums. They could push commercial vessels to alter routes. The economic impact depends on what happens next.
For now, the incident is diplomatic and military. It is not a market shock. But naval watchers should file it away as part of a longer pattern.
The Final Thoughts
A Pakistani Navy Hunain-class corvette crossed paths with an Indian Navy warship in the North Arabian Sea. The Pakistani ship maneuvered aggressively. The hulls grazed. India protested. Pakistan has not responded.
No one died. No ship sank. But the 1991 agreement exists for a reason. Close maneuvers at sea kill people when they go wrong. This one did not. Next time might be different.
