State media on Tuesday published images of an unveiling ceremony, attended by President Ebrahim Raisi and senior commanders of the Islamic Revolutionary Guard Corps (IRGC), with the domestically made black missile visible.

State media said the missile can move at a speed of up to Mach 15 (5,145 metres or 16,880 feet per second), has a range of 1,400km (870 miles) and features a moveable secondary nozzle and employs solid propellants that allow for high manoeuvrability.

Supreme Leader Ayatollah Ali Khamenei has chosen the name, they said, which roughly translates to “the opener”.

Hypersonic missiles move at five times the speed of sound or greater and are manoeuvrable, making them difficult for defence systems and radars to target.

In November, Hajizadeh said the new missile represents a “generational leap” for Iranian missile technology as it can manoeuvre within and outside the earth’s atmosphere and penetrate any missile defence system.

“The Fattah cannot be destroyed by any other missile due to how it moves in different directions and at different altitudes,” he was quoted as saying on Tuesday.
