Iranian state television said the first Iranian-built destroyer was launched on Friday in a ceremony attended by Supreme Leader Ayatollah Ali Khamenei.
"The first domestically made destroyer Jamaran was launched this morning and joined Iran's naval forces in the southern waters of the Persian Gulf," state television IRIB reported. It did not give the location of the launch.
The report showed footage of the warship and said it was equipped with torpedoes and electronic radar. The ship is 94 metres long and more than 1,500 tonnes, it said. Much of Iran's naval equipment dates from before the 1979 Islamic revolution and is U.S.-made.
