Chokepoint Guide
Gulf of Oman
Strategic staging area between the Strait of Hormuz and Arabian Sea
Overview
The Gulf of Oman is a body of water connecting the Arabian Sea with the Strait of Hormuz and the Persian Gulf. It is bordered by Oman and the UAE to the south, Iran to the north, and Pakistan to the east. The gulf is approximately 560 kilometers long and 320 kilometers wide. It serves as the primary staging area for tankers loading in the Persian Gulf before transiting to global markets, and as the principal operating zone of the US Navy's Fifth Fleet.
Strategic Importance
The Gulf of Oman is the immediate downstream chokepoint from the Strait of Hormuz. All tankers departing the Persian Gulf must transit the Gulf of Oman before reaching the Arabian Sea and global shipping routes. It is also the site of major offshore oil loading terminals (Single Point Moorings / SPMs) serving Saudi Arabia, Oman, and the UAE. The Fujairah anchorage, located on the UAE coast of the Gulf of Oman, is one of the world's largest ship-to-ship transfer and bunkering hubs.
Key Facts
All Persian Gulf oil exports must pass through the Gulf of Oman
Fujairah (UAE) is one of the world's largest bunkering and ship-to-ship transfer hubs
The IRGCN operates extensively in the gulf and has seized vessels in international waters here
The 2019 limpet mine attacks on tankers off Fujairah occurred in the Gulf of Oman
The US Fifth Fleet and Combined Maritime Forces operate in the gulf
The narrow approaches to the Strait of Hormuz create chokepoints within the gulf itself
Iran's coast and territorial waters extend significantly into the northern gulf
Current Risk Assessment
The Gulf of Oman is a persistent medium-to-high risk zone for commercial shipping. The IRGCN has carried out multiple vessel seizures in the gulf in international waters, including the Advantage Sweet (2023), the St Nikolas (2024), and attempted seizures of US naval vessels (2022). The US Navy maintains a continuous surface and air patrol presence, but this has not prevented all IRGCN boarding operations. The risk of vessel seizure or interference is elevated for any vessel with links to Israel, the UK, or US-sanctioned entities.
Historical Context
The Gulf of Oman gained international attention during the 2019 tanker attacks, when limpet mines damaged four vessels near Fujairah in May 2019, and the front Altair and Kokuka Courageous were struck in June 2019 — both attacks attributed by the US to Iran. The IRGCN seized the British-flagged Stena Impero in the gulf in July 2019. These incidents established the gulf as a contested zone for commercial shipping under Iranian pressure.
