The Islamic Republic of Iran Navy (IRIN) launched an anti-ship missile from a Ghadir-class submarine during ‘Velayet 97’ naval exercises in the Persian Gulf. According to Iranian officials, the missile was developed as part of the Jask-2 project and is based on a longer-range version of the Nasr missile. The Nasr is a solid propellant missile based on China's C-704, with a range of 38 km when launched from the surface. Video footage suggests that the missile may have been launched from beneath the surface.
