Indian authorities have intensified enforcement against the Iranian shadow oil fleet after detaining three oil tankers linked to fuel smuggling operations in the Arabian Sea. The operation, conducted on February 5–6, 2026, was led by the Indian Coast Guard following the detection of suspicious vessel movements approximately 100 miles west of Mumbai. Officials said tech-enabled surveillance and data-pattern analysis revealed coordinated activity consistent with illicit oil transfers.
Coordinated sea–air interdiction
According to the Coast Guard, the smuggling network relied on illegal ship-to-ship transfers in international waters to move low-cost petroleum products from conflict-affected regions while evading customs duties. Sustained inspections, electronic data corroboration, and crew interrogations exposed a sophisticated modus operandi supported by a global handler network. Authorities also noted that the vessels frequently changed identities and flags to avoid detection. The three ships were intercepted and escorted to Mumbai for further legal proceedings, reinforcing India’s role as a net provider of maritime security.
Sanctioned vessels and regional context
The seized tankers were identified as the 50,000-dwt Chiltern (built 1999), formerly Al Jafzia, the 16,800-dwt Asphalt Star (built 2007), and the 6,200-dwt Stellar Ruby (built 2010). Investigations confirmed false flag registrations and ownership links to UAE-based entities already under United States sanctions. Iranian media reported the vessels were sanctioned in 2025. The operation comes amid heightened regional enforcement, including recent tanker seizures linked to fuel smuggling in the Middle East Gulf and near the Strait of Hormuz.
