Iran launches sub as US, allies hold massive naval drills in Persian Gulf

 

DUBAI -- Iran launched a submarine and a destroyer into the Persian Gulf from Bandar Abbas port on Tuesday at the same time as U.S. and allied forces held massive naval exercises in the same waters to practice keeping oil shipping lanes open.

Tehran has repeatedly threatened to close the Strait of Hormuz, a route for oil exports from the gulf, if Iranian nuclear sites are attacked by Israel, which believes Tehran is trying to develop an atomic bomb.


The United States, Britain, France and a number of Middle Eastern states are conducting a naval exercise in the gulf this week, focusing on how to clear mines that Tehran or guerilla groups might deploy to disrupt tanker traffic.

The exercises, with 25 countries participating, are the largest ever of its kind in the region, according to Britain’s Telegraph newspaper 

The multinational force includes three U.S. Nimitz class carrier groups, each of which has more aircraft than Iran’s entire air force, the newspaper said.

The force is also supported by at least 12 battleships, including ballistic missile cruisers, frigates, destroyers and assault ships, which carry thousands of U.S. Marines and special forces, the Telegraph reported.
