Iran's Islamic Revolution Guards Corps (IRGC) unveiled what it described as unique hypersonic ballistic missile that cannot be intercepted by existing missile defences on 6 June.
The IRGC claimed the Fattah missile that was unveiled during an event attended by President Ebrahim Raisi has a range of 1,400 km, is highly manoeuvrable, and can hit its target accurately at a speed of Mach 13–15.
“It will be impossible to counter a missile with such a speed,” said IRGC Aerospace Force command Brigadier General Amir Ali Hajizadeh.
The Fattah displayed at the event looked similar to later versions of the Fateh-110 family of solid-propellant ballistic missile that have fins on their re-entry vehicles (RVs) so they can steer towards their target in their terminal phase inside the Earth's atmosphere.
The missile was displayed next to what was identified as a spherical solid-fuel rocket motor that powers the RV after it separates from the main rocket motor. The motor reportedly has a movable nozzle that enables the RV to change direction.
A video was released that showed a launch of what looked like a Fateh-110-type missile and computer-generated imagery showing the RV using its motor to manoeuvre outside the Earth's atmosphere. The motor was shown still burning after re-entry even though the RV has aerodynamic control surfaces for steering as air density increases in its terminal phase.
