TEHRAN (AFP) Iran kicked off mass production of two high-speed missile-launching assault boats on Monday, warning its enemies not to play with fire as it boosts security along its coastline. The inauguration of the production lines for the Seraj and Zolfaqar speedboats comes a day after President Mahmoud Ahmadinejad unveiled Irans home-built bomber drone, which he said would deliver death to Irans enemies. State news agency IRNA reported that Seraj (Lamp) and Zolfaqar (named after Hazrat Alis (RA) sword) speedboats would be manufactured at the marine industries complex of the ministry of defence. Defence Minister Ahmad Vahidi opened the assembly lines, saying the vessels would help strengthen Irans defence forces, IRNA said. Today, the Islamic Republic of Iran is relying on a great defence industry and the powerful forces of Sepah (Revolutionary Guards) and the army, with their utmost strength, can provide security to the Persian Gulf, the Sea of Oman and Strait of Hormuz, Vahidi said. He issued a stern warning to Irans foes. The enemy must be careful of its adventurous behaviour and not play with fire because the Islamic Republic of Irans response would be unpredictable, IRNA quoted him as saying. If enemies attack Iran, the Islamic Republic of Irans reaction will not be restricted to one area. The truth of our defence doctrine is that we will not attack any country and that we extend our hand to all legitimate countries. IRNA said Zolfaqar was a new generation missile-launching vessel which can be used for patrol as well as for attack operations. It is designed for quick assaults on ships and is equipped with two missile launchers, two machine guns and a computer system to control the missiles, the report said. Fars news agency cited Vahidi as saying that Zolfaqar was to be equipped with the Nasr 1 (Victory) marine cruise missile which has high destructive power. Iran has previously said that the Nasr missile can destroy targets weighing up to 3,000 tonnes. IRNA said Seraj, designed for a tropical climate, was also a swift assault vessel for use in the Caspian sea, the Gulf and the Gulf of Oman, adding that it can fire rockets and also be used in stormy seas. Seraj is a fast moving assault rocket launcher using sophisticated and modern technology, Vahidi was cited as saying by IRNA. The launch of the production lines comes as Iran marks its annual government week, a period when it traditionally shows off its latest technological achievements.
