Iran is repairing and preparing its air defense systems, battered last year by Israel, to be ready against a possible US or Israeli strike on its nuclear sites, the Financial Times reported, citing analysts familiar with Western intelligence assessments and satellite imagery.

Data indicates that Iran has relocated a number of air defense systems, including Russian-made S-300 launchers, to prime nuclear sites, among them its uranium enrichment facilities in Natanz and Fordo.

“We are witnessing a remarkable improvement in the capability and readiness of the country’s air defense,” Mohammad Bagheri, the chief of staff of Iran’s armed forces, said last month, according to the Sunday report. “The enemies of the Iranian nation must understand that any violation of our country’s airspace will inflict significant damage upon them.”
