At least one officer has reportedly died and several injured during a navy exercise at the port of Jask, just off the Gulf of Oman, according to state TV on Monday.
The accident was allegedly the result of friendly fire, taking place during a live-fire drill.
The ship that was hit was reportedly a missile-launching warship.
An investigation into the circumstances is underway.
