Fattah-1

Iran's most advanced operational ballistic missile — a solid-propellant medium-range weapon with a powered maneuvering re-entry vehicle, marketed by Tehran as "hypersonic," and the centerpiece of its evolving effort to defeat regional missile defenses.

Overview

The Fattah-1 (Persian فتاح, "conqueror" or "the opener" — a name chosen personally by Supreme Leader Ali Khamenei) is a solid-propellant medium-range ballistic missile with a powered maneuvering re-entry vehicle, fielded by the Islamic Revolutionary Guard Corps Aerospace Force. Iran unveiled the weapon in June 2023 and promoted it as its "first hypersonic missile" — a label independent analysts dispute as obscuring more than it illuminates. It is the first Iranian missile designed from the outset to maneuver both inside and outside the atmosphere, using a small solid rocket motor with thrust-vector control in the re-entry vehicle to evade terminal and — Tehran claims — midcourse missile defenses. Debris analysis by independent researchers confirmed its combat use against Israel in 2024, and Iranian state media asserted further Fattah-1 launches in the June 2025 and 2026 escalation cycles.

Development

The IRGC Aerospace Force announced the development of a "hypersonic ballistic missile" on 10 November 2022, with commander Amir Ali Hajizadeh describing it as a "major generational leap" capable of breaching all anti-missile defense systems and predicting that countering it would take decades. The missile was formally unveiled as the Fattah-1 on 6 June 2023 at a ceremony attended by President Ebrahim Raisi, according to Al Jazeera. Hajizadeh claimed a range of 1,400 km, speeds of Mach 13–15, and the ability to maneuver both inside and outside the atmosphere via a movable nozzle on the second-stage motor.

Fabian Hinz of the International Institute for Strategic Studies assessed the Fattah-1 as a logical next step in Iran's incremental missile development — progressing from terminal course-correction on the Kheibar Shekan (2022) to sustained evasive maneuvering — and noted the IRGC likely unveiled it in institutional rivalry with the defense ministry's MODAFL, which had showcased its own Khorramshahr-4 days earlier, per IISS. The Iran Watch database identifies the booster as derived from the Kheibar Shekan design and classifies the re-entry-vehicle motor as post-boost propulsion rather than a true second stage. The same source notes the missile had reached deployed status by the time of its first assessed combat use in April 2024.
