“Fattah is a precision-guided two-stage solid-fueled missile with a range of 1400 km and terminal speed of Mach 13 to Mach 15. Its warhead has a spherical engine running on solid fuel with a movable nozzle that allows the warhead to increase its own speed and move in all directions.”
A container ship in the Indian Ocean can protect itself from a precision guided missile arriving at Mach 15? If you say so.
All of the claims regarding Fattah including the Wikipedia excerpt you just posted are just that — claims. AFAIK, there is no evidence of any kind of airborne testing much less deployment. In addition, there is reason to believe the technology is immature as the claimed propulsion method suddenly changed from solid fuel to liquid fuel. It is difficult to get maneuverable hypersonic technology right — we continue to have both successes and failures to this day.
A claim. Not a fact. And besides it is still a ballistic missile, not a hypersonic missile which is completely different.
All ballistic missiles have high terminal velocities.
Don’t confuse such a missile with a hypersonic glide vehicle.
