Fattah-1

Fattah-1 () is an Iranian medium-range ballistic missile developed by the Islamic Revolutionary Guard Corps and unveiled in June 2023. Iran has described the missile as "hypersonic", a description which has been noted as "dubious" by several media outlets including Calcalist, the Times of Israel and The War Zone; and by analyst Fabian Hinz as "obscur[ing] more than it illuminates." According to Iran, its high maneuverability and speed helps it to evade missile defense systems. In November 2023, Iran unveiled a newer version of the missile, Fattah-2.

== Description == According to Iran, it can maneuver in and out of the atmosphere, and is capable of bypassing missile defenses. Iran describes it as a hypersonic missile. However, according to Fabian Hinz, research fellow for Defense and Military Analysis at the International Institute for Strategic Studies, Fattah does not fall under the general classification of hypersonic weapons, but is rather a medium-range ballistic missile (MRBM) that has a “second stage [that] incorporates the warhead, aerodynamic controls and a small solid-propellant motor with a moveable nozzle for thrust vector control (TVC) that resembles a maneuverable reentry vehicle (MaRV)" rather than a hypersonic glide vehicle, meaning it can only maneuver for a short part of the flight in the terminal phase. Hinz noted that “Iran attempted to overcome this limitation by mating a small TVC rocket motor to a MaRV, enabling exo-atmospheric maneuvering."
