Greater Tunb Island
 
Why in News?
Greater Tunb Island is heavily in the news because the U.S. Central Command (CENTCOM) launched intensive, 90-minute daylight airstrikes targeting Iranian coastal defence batteries and cruise missile installations located on the island.
 

Geography, Location and Sovereignty Dispute
  • Strategic Coordinates: It is a tiny island measuring roughly 10.3 square kilometres situated in the Persian Gulf.
  • Choke Point Sentinel: It sits directly at the entrance of the narrow Strait of Hormuz, a vital maritime gateway through which roughly 20% (one-fifth) of global oil supplies pass daily.
  • The Trio: Greater Tunb, alongside Lesser Tunb and Abu Musa, forms a group of three highly contested islands.
  • The 1971 Takeover: The Iranian military seized control of these islands in November 1971, just as British forces were withdrawing from the region.
  • UAE Claims: The UAE considers the islands an integral part of its sovereign territory (originally belonging to the Emirate of Ras Al Khaimah) and formally labels Iran's decades-long administration as an illegal occupation.
Militarization as an "Unsinkable Aircraft Carrier"
  • Garrison Fortifications: Under de facto Iranian control, the island has been heavily fortified by the Islamic Revolutionary Guard Corps (IRGC).
  • Tactical Advantage: Iran uses its network of islands to blanket the commercial shipping lanes with surveillance radars, fast-attack speedboats, kamikaze drones, and anti-ship missiles.
  • Control of the Gulf: Analysts note that controlling Greater Tunb provides immense military leverage, allowing any occupying force to effectively monitor or completely freeze maritime traffic entering or exiting the Arabian Gulf.
