Iran's navy commander Rear Admiral Habibollah Sayyari says the country's military doctrine rests on preventive defense strategies.
Addressing navy students on Monday, Adm. Sayyari said only a strong naval force could vigorously defend national interests against the enemy.
Pointing to Iran's outstanding military might, the Iranian commander said, "Today the Islamic Republic's Naval Forces enjoy a high level of defensive and offensive capabilities".
He added that under the guidance of the Leader of the Islamic Revolution, the Iranian navy had reached a level of self-sufficiency in producing its required technology.
The imposition of sanctions on Iran has encouraged a campaign for self-sufficiency in the country's defense industry.
What the Admiral is pointing out is that Iran's defense is based on deterrence, and that a relatively strong and naval presence is required in the Persian Gulf to protect Iran's national interest. He also points out the ability of the Iranian defense industry to equip the IRIN with indigenously manufactured weapon systems such as missile boats and anti-ship missiles.
