Iran launched production of its most advanced cannon on Wednesday, state television reported.
"The cannon Fajr-27 has the capability of automatically firing 85 76-milimeter bullets per minute," Gen. Mostafa Mohammad-Najjar, Iran's defense minister, told the broadcast.
He said the cannon has an aerial range of 7,010 meters (23,000 feet) and a 17-kilometer (10.5-mile) surface range.
Since 1992, Iran has produced its own tanks, armored personnel carriers and missiles. In 2005, the government said that it had begun producing torpedoes.
