Iran has apparently built a mock-up of an American aircraft carrier. This is shown by recently discovered satellite images. The structure is about a third smaller than the original Nimitz ships.
Official information about the purpose of the replica is not known. In 2015 the Revolutionary Guards had used a similar mock-up for propaganda and training purposes: More than 400 grenades were fired at it within 15 minutes.
There are even fake fighter jets on the deck of the ship. It was probably sunk by the paramilitary Revolutionary Guard. A warning to the USA ?
