"Right now we are at the initial phases of manufacturing atomic submarines," Rear Adm. Abbas Zamini of the Iranian navy's technical affairs department told the semi-official Fars news agency.
Zamini said nuclear-powered submarines fall within the realm of civilian use of nuclear technology and all countries have the right to manufacture them.
Last year the Younus, a Tareq class submarine, spent 68 days in international waters, accompanying the navy's 14th fleet on maneuvers in the Red Sea and the Gulf of Aden, Fars said.
