What is the common examiner trap about Intl. Relations in UPSC exams?

Examiners may swap 'Strait of Hormuz' with 'Strait of Malacca' or 'Bab-el-Mandeb' to test location knowledge. They may also confuse 'Omani corridor' with 'Iranian corridor' or claim that all India-flagged ships kept transponders on (only 2 of 4 did).

What should UPSC aspirants remember about Intl. Relations for Prelims?

1. Target this Data: 62% of India-bound ships (45 out of 73) went dark in Strait of Hormuz between May 1 and June 25, 2026. 2. Target this Nodal Body: International Maritime Organization (IMO) - recognized the US-Oman escorted transit operations. 3. Target this Legal Point: SOLAS convention mandates continuous AIS broadcasting; 'going dark' is a violation.

62% India-Bound Ships Go Dark in Strait of Hormuz Amid Iran Attack Risk

Q: Which international convention mandates that ships continuously broadcast their identity and location using AIS transponders?

SOLAS (Safety of Life at Sea) Convention, The SOLAS convention, under the International Maritime Organization (IMO), requires vessels over 300 gross tonnage to carry and operate AIS transponders at all times. 'Going dark' violates this requirement.

The Omani coastline route is officially recognized by Iran as a safe corridor. 3. The India-flagged tanker Sanmar Herald was attacked by Iranian forces after receiving clearance from the IRGC navy. Which of the statements given above is/are correct?

Both 1 and 3, Statement 1 is correct: 45 of 73 ships (62%) went dark. Statement 2 is incorrect: the Omani route is backed by the US and Oman but is NOT recognized by Iran. Statement 3 is correct: the Sanmar Herald was cleared by IRGC navy before being attacked.

Q: According to the article, how many India-flagged ships crossed the Strait of Hormuz during the observation period, and how many of them switched off their trackers?

4 ships; 2 switched off, The article states that only four India-flagged ships made the crossing during this period. Two switched off their trackers, while the remaining two continued broadcasting.

Q: What is the primary strategic concern for India arising from the 'going dark' trend in the Strait of Hormuz?

Threat to energy security due to disruption of crude oil imports, The Strait of Hormuz is a critical chokepoint for India's crude oil imports. Ships going dark and facing attacks directly threaten the steady supply of oil, impacting India's energy security and economic stability. While legal and revenue aspects exist, the core concern is energy security.

Ships 'Going Dark'

45 of 73 India-bound vessels switched off AIS transponders in the Strait of Hormuz to avoid Iranian attacks.

🗺️

Route Shift to Omani Coast

Ships are increasingly using the US-Oman backed corridor instead of Iranian-controlled lanes for safety.

⚔️

Iranian Attacks Despite Clearance

Iran attacked the India-flagged tanker Sanmar Herald even after IRGC navy had cleared its passage.

Detailed Analysis & Strategic Depth

Context / Background

The Strait of Hormuz is a strategic chokepoint connecting the Persian Gulf to the Arabian Sea, through which about 20% of global oil passes. Since late February 2026, the West Asia conflict escalated, with Iran repeatedly changing transit rules and attacking vessels. India imports a significant portion of its crude oil via this route, making the crisis a direct threat to energy security.

Core Analysis & Implications

The 'going dark' tactic (switching off AIS transponders) violates international maritime law requiring continuous broadcasting of identity and location. However, ships prioritize safety over compliance in high-risk zones. The shift to the Omani corridor, while safer, is not recognized by Iran and has seen attacks even there (e.g., the India-flagged cargo vessel sunk near Limah). This creates a dilemma for India: protect its shipping lanes without direct military confrontation.

Future Outlook / Way Forward

US-led escort operations were scaled back within days, leaving ships vulnerable. India may need to enhance its own naval presence or coordinate with Oman and the US for secure corridors. The crisis also underscores the need for diversifying oil import sources and strengthening alternative routes (e.g., via the Red Sea or pipelines) to reduce dependence on the Strait of Hormuz.
