TEHRAN: Iran has successfully tested surface-to-sea missiles with a range of 110 kilometres, state television reported on Monday. The testing of the Silkworm missiles was the most important project of Monday's military manoeuvres in southern Iran, the television said. It said the Silkworms have a speed of 290 kilometres per second and a range of 110 kilometres. They can detect targets from a distance of 15 kilometres and have the capacity to destroy a warship. The report did not say whether the missiles could carry nuclear warheads. Iran's armed forces began their biggest military manoeuvres on Friday in national waters in the Sea of Oman and Indian Ocean, close to Pakistan.
