What Happened
- Eight India-bound ships carrying energy cargo — crude oil, LPG, and LNG — were forced to return after attempting to cross the Strait of Hormuz when Iran reimposed strict military controls.
- The government had coordinated with Iranian agencies and the Indian Navy to earmark 22 ships carrying energy cargo for repatriation, of which 10 had successfully crossed by this point.
- The Indian Navy's Operation Urja Suraksha, launched on March 25, deployed more than five frontline warships — including Visakhapatnam-class destroyers and frigates — in the Gulf of Oman to escort vessels after they cleared the Strait.
- Warships did not enter the Strait of Hormuz itself but maintained a security perimeter at its exit in the Gulf of Oman, providing navigation and communication support.
- Initially 25 Indian-flagged vessels were stranded west of the Strait; by April 18, ten had successfully transited but eight were forced back after Iran's sudden reimposition of restrictions.

India's Energy Security and Import Dependence
India is the world's third-largest oil importer, sourcing roughly 85% of its crude oil requirements from abroad. The West Asia region — including Iraq, Saudi Arabia, UAE, and historically Iran — accounts for the bulk of these imports. Nearly 40% of India's crude imports and approximately 50% of its liquefied natural gas (LNG) imports flow through the Strait of Hormuz, making any disruption there a direct threat to domestic energy availability and price stability.
- India imports approximately 4.5–5 million barrels of crude oil per day
- Top crude oil suppliers: Iraq (~20%), Saudi Arabia (~17%), UAE (~10%), Russia (~19–20%) as of 2024–25
- Strategic Petroleum Reserve (SPR): India maintains underground rock cavern reserves at Vishakhapatnam, Mangaluru, and Padur — totalling ~5.33 million metric tonnes (about 9–10 days of crude requirements)
- India is an associate member of the International Energy Agency (IEA), not a full member, limiting its access to coordinated emergency oil release mechanisms
- Energy security is listed among India's highest strategic priorities, with EAM Jaishankar making a suo motu statement in Rajya Sabha on March 9, 2026
Connection to this news: The forced return of India-bound energy ships directly threatens the country's fuel supply chain, exposing the structural vulnerability of routing energy through a single, politically contested chokepoint.
Operation Urja Suraksha
Operation Urja Suraksha ("Energy Security Operation" in Hindi) is an Indian Navy mission launched on March 25, 2026, to provide escort and navigational protection to Indian-flagged merchant vessels stranded west of the Strait of Hormuz due to the ongoing Iran-related hostilities. It is one of India's largest peacetime naval deployments for energy security in the Persian Gulf region.
- Launched: March 25, 2026
- Deployed assets: More than five frontline warships — Visakhapatnam-class destroyers and frigates
- Area of operation: Gulf of Oman (just east of the Strait exit); warships did NOT enter the Strait or Persian Gulf
- Scope: 22 vessels identified for repatriation, 20 carrying high-priority energy cargo (LNG, LPG, crude oil)
- Method: Coordinating with Iran for clearance to transit the Strait, then escorting ships through the Gulf of Oman
- By April 18: 10 vessels had successfully transited; 8 forced back after Iran reimposed restrictions
Connection to this news: Operation Urja Suraksha represents India's direct use of naval power for energy security, a significant precedent in India's strategic posture in the Indian Ocean Region (IOR).
Freedom of Navigation and UNCLOS
The United Nations Convention on the Law of the Sea (UNCLOS), adopted in 1982 and in force since 1994, is the primary international legal framework governing use of the world's oceans. Under UNCLOS, the right of "transit passage" through international straits used for navigation — including the Strait of Hormuz — cannot be suspended even by the coastal state. India, as a maritime nation and major UNCLOS signatory, has consistently advocated for freedom of navigation as a non-negotiable principle.
- UNCLOS adopted: 1982; entered into force: November 1994
- India ratified UNCLOS in 1995
- Article 38 of UNCLOS: All ships and aircraft enjoy the right of transit passage through straits used for international navigation
- Coastal states may regulate (not prohibit) transit passage for safety and environmental reasons
- India's Foreign Secretary Vikram Misri reiterated at a UK-hosted conference in April 2026 that "freedom of navigation and unimpeded transit through international straits are non-negotiable"
Connection to this news: Iran's restrictions on Indian-flagged vessels contradict the transit passage rights guaranteed under UNCLOS, placing India's diplomatic protest on firm legal footing.
