Iran's state TV is showcasing additions to its Navy including a missile-launching warship around the size of a frigate.
Navy officials watched as the domestically-produced Sina-7, equipped with anti-ship missiles, was launched Wednesday at Bandar Abbas, near the strategic Strait of Hormuz. Two new Iranian-built Ghadir submarines and two repaired hovercrafts were also delivered to the Navy.
The TV quoted Navy chief Rear Admiral Habibollah Sayyari as saying that Iran must possess the "newest technology and top-grade facilities to protect its borders."
Ghadir class submarines can fire missiles and torpedoes at the same time, and can operate in the Persian Gulf's shallow waters.
Iran has sought to upgrade its air defense and naval capabilities, saying any possible future attacks on it would come from the air and sea.
