The U.S. military says it targeted the Iranian naval drone carrier IRIS Shahid Bagheri during the initial wave of strikes against Iran on Saturday.

U.S. Central Command dismissed Iranian claims that an American aircraft carrier had been sunk, calling them false and stating that the only carrier struck was Iran’s Shahid Bagheri.

According to CENTCOM, U.S. forces hit the vessel within hours of initiating Operation Epic Fury.
