The rocket tests were carried out last Saturday in the Strait of Hormuz, which runs between Oman and Iran, not only coming close to U.S. ships, but also commercial traffic and a French military frigate.
The decision by the Iranian navy to carry out the tests in such close proximity to western vessels has caused new tension between the two nations after a landmark nuclear deal was reached earlier this year.
Commander Kyle Raines, a U.S. Central Command spokesman, said Iran's 'actions were highly provocative'.
'Firing weapons so close to passing coalition ships and commercial traffic within an internationally recognized maritime traffic lane is unsafe, unprofessional and inconsistent with international maritime law,' he said.
In a statement, the U.S. said Iranian Revolutionary Guard naval vessels fired 'several unguided rockets' about 1,500 yards from the USS Harry S. Truman aircraft carrier, the USS Bulkeley destroyer and a French frigate, the FS Provence.
