Carrier Strike Group 10, headed by the USS Harry S. Truman aircraft carrier, sails out of the US Navy base at Norfolk, Virginia Friday, May 21. On arrival, it will raise the number of US carriers off Iranian shores to two. Up until now, President Barack Obama kept just one aircraft carrier stationed off the coast of Iran, the USS Dwight D. Eisenhower in the Arabian Sea, in pursuit of his policy of diplomatic engagement with Tehran.

For the first time, too, the US force opposite Iran will be joined by a German warship, the frigate FGS Hessen, operating under American command.

Our military sources have learned that the USS Truman is just the first element of the new buildup of US resources around Iran. It will take place over the next three months, reaching peak level in late July and early August. By then, the Pentagon plans to have at least 4 or 5 US aircraft carriers visible from Iranian shores.
