Iranian Navy Commander Rear Admiral Habibollah Sayyari said his forces are working on three new destroyers, noting that they are the upgraded versions of Jamaran-class warships.

The new destroyers known as Jamaran-3, 4 and 5 are being manufactured by the Iranian experts, and will be unveiled respectively in the future, Sayyari told reporters in the northern port city of Anzali on Friday.
The Iranian Navy launched its first domestically-built destroyer, Jamaran, in the waters of the Persian Gulf in February 2010.
