Russia offers Iran latest anti-ballistic missile system, Antey-2500

Russia has offered Iran the chance to buy its latest Antey-2500 anti- aircraft and ballistic missile system, instead of the older S-300 system.
Iran is considering deal. No decision has been made yet," Rostec CEO Sergei Chemezov said while speaking at an international arms show in Abu Dhabi, Saudi Arabia, according to TASS.
Antey-2500 is an improved version of the S-300, which Russia has stopped manufacturing. Under contract signed in 2007 by the two countries, Russia was to deliver S-300 air defense missile systems to Iran. However, the deal was canceled in 2010 by then-Russian President Dmitry Medvedev, following UN sanctions imposed on Iran due to its disputed nuclear program. In turn, Tehran filed a currently pending $4 billion lawsuit against Russia with Geneva's arbitration court.
