TEHRAN (AFP) - Defence Minister Ahmad Vahidi announced on Friday that Iran has test fired a surface-to-surface missile, Qiam, a day before it is due to launch its Russian-built first nuclear power plant. State television showed images of the sand coloured Qiam (Rising) blasting into the air from a desert terrain, amid chants of Allahu Akbar. The words Ya Mahdi were written on the side of the missile. Vahidi, whose speech during Friday prayers in Tehran was broadcast on television, did not say when the launch took place nor did he reveal the precise range of the missile. Fars news agency had in a report earlier this week quoted the minister as saying that Qiam was a short-range missile. The missile has new technical aspects and has a unique tactical capacity, he said on Friday, adding that the device was of a new class. Since the surface-to-surface missile has no wings, it has lot of tactical power, which also reduces the chances of it being intercepted, he said. Irans ISNA news agency cited Vahidi as saying that Qiam was entirely designed and built domestically and was powered by liquid fuel. This missile is capable of hitting the target with high precision, Vahidi said. On Tuesday, Vahidi had said that Qiam was to be test fired during the annual government week, the period when Tehran touts its achievements in various fields. This year government week begins on Monday. The third generation Fateh 110 missile was also to be test fired during this period. Iran has previously paraded a version of Fateh 110 which has a travel range of 150 to 200 kilometres. Also during government week, the production lines of two missile-carrying speedboats, Seraj (Lamp) and Zulfiqar are due to be inaugurated, while a long-range drone, Karar, is expected to be unveiled. The firing of Qiam comes days after Iran took delivery of four new mini-submarines of the home-produced Ghadir class. Weighing 120 tonnes, the stealth submarines are aimed at operations in shallow waters, notably in the Gulf.
