The naval exercises, codenamed The Great Prophet-9, are held in the Strait of Hormuz, known as the most strategic waterway in the Persian Gulf.
Hundreds of speedboats, armed with missiles, were deployed to take action in the drills. They carried out mine-laying operation in the drill zone and also fired hundreds of 107mm rockets to hit a mock warship, a real-size model of a Nimitz-class aircraft carrier.
Moreover, four Iranian “Nasr” cruise missiles were fired from the coast to hit the model warship. The Nasr is a short-range coast-to-sea missile, which is capable of detonating targets weighing 3,000 tons.
The IRGC also fired a number of “Persian Gulf” ballistic missiles from the eastern coasts of the port of Jask to sink the hypothetical enemy warship. The Persian Gulf is a ballistic missile with pin-point accuracy and a range of above 270 kilometers.
The Strait of Hormuz, a narrow waterway between Iran and Oman, connects the Persian Gulf with the Sea of Oman.
It is the only sea passage from the Persian Gulf to the high seas and is one of the world's most strategically-important choke points.
