Iran will soon unveil a domestically-made air defence system with at least the same capability as Russia's S-300 anti-aircraft hardware, an Iranian air force commander was quoted as saying on Monday.
Last month, Russia's state arms trader declined to say whether it would go ahead with the sale of S-300 to Iran, which could protect the Islamic Republic's nuclear facilities from air strikes.
Iranian officials have expressed growing irritation at Russia's failure so far to supply the missile system.
"The only equipment we wanted to import from abroad was the S-300 ... which Russia, based upon unacceptable reasons, has not delivered yet," the official IRNA news agency quoted commander Heshmatollah Kassiri as saying.
"In the near future, a new locally-made air defence system will be unveiled by the country's experts and scientists which is as powerful as the S-300 missile defence system, or even stronger," he said.
The truck-mounted S-300PMU1, known in the West as the SA-20, can shoot down cruise missiles and aircraft. It has a range of 150 km (90 miles) and travels at more than two km per second.
"The country's air defences are strong enough to confront the enemies ... and we will never let them get close to our sensitive nuclear centres," Kassiri said.
Israel, most experts estimate that it has at least between 100 and 200 nuclear warheads, often threatens Iran with an attack.
