In the video, Iranian navy commander Habibollah Sayyari also boasted of the country's ability to build its own destroyers and submarines.
Thanks to the Islamic Revolution, Iran has acquired the know-how to build submarines. No one believed that we would reach a point where we would build destroyers capable of carrying helicopters and missiles in the Sea of Oman and oceans … because it’s a very difficult task to build destroyers and submarines.
Iran also showcased a hovercraft, which looked similar to the one they unveiled a few weeks ago. Iran's defense minister was quoted saying the hovercraft would be used for "offensive reconnaissance operations" and "midrange amphibious missions." Take a look at the video of the hovercraft during an exercise:
The unveiling of these navy vessels comes a day after the Associated Press reported that a diagram leaked by officials from a country critical of Iran’s atomic program shows the country is working on a nuclear bomb more powerful than the one that destroyed Hiroshima.
The New York Times' Thomas Erdbrink tweeted that Iran has also said that it will be announcing "new details" about the RQ-170 drone that the country claimed to have downed last year.
CORRECTION: An earlier version of this post incorrectly said that Iranian officials leaked the diagram. The diagram was leaked by officials from a country critical of Iran’s atomic program, according to AP. The post has been updated.
