Iran destroyed a dummy US aircraft carrier with missiles in the strategic Strait of Hormuz.
The drill included fire so heavy that the US military temporarily put two regional bases on alert.
The US navy condemned the “irresponsible and reckless behaviour by Iran”, labelling it an attempt “to intimidate and coerce”.
The exercise comes at a time of increased tension between Tehran and Washington in the Gulf waters.
The drills dubbed as Prophet Mohammed 14th were broadcasted on state television.
The mock-up – which resembles a carrier the US routinely sails into the Gulf – is shown with dummy fighter jets on either side of its landing strip. Missiles are then launched from a variety of angles, including some aimed at the carrier.
Another missile fired from a helicopter appears to hit the side of the fake warship.
“What was shown today in these exercises, at the level of aerospace and naval forces, was all offensive,” Iran’s Revolutionary Guards commander Major General Hossein Salami told state television.
The missile fire were detected by US troops putting them on alert in UAE and Qatar.
