The Khordad 15 is an Iranian designed and built surface-to-air missile (SAM) system. The system was unveiled to the public on 9 June 2019 in an address made by Iranian Defence Minister in Tehran, Iran. The system was developed by the Iran Aviation Industries Organization (IAIO). It has the capability to detect and intercept fighter jets, stealth targets, unmanned combat aerial vehicles (UCAV) and cruise missiles. It operates in conjunction with Sayyad-3 missiles. The surface-to-air missile system was developed in order to counter missiles and other aerial threats presented by the presence of extra-regional forces at military bases in countries around Iran.[citation needed] It was unveiled amid escalating tensions with the United States and Europe's failing attempts at upholding its commitments to the 2015 Iran nuclear deal.
