Direct proof of use
Fattah-1's documented appearance in the 2025 Israel-Iran Conflict rests on Iranian official claims and independent reporting of those claims. Press TV, citing an IRGC announcement, reported early on June 18, 2025 that first-generation Fattah missiles were used in the eleventh phase of Operation True Promise III. The Associated Press reported the same day that Iran's Revolutionary Guard claimed to have fired hypersonic Fattah-1 missiles toward Israel.
The evidence supports Iranian claimed firing of Fattah-1 as part of a retaliatory long-range missile salvo against Israel. It does not by itself verify every Iranian performance claim, named target claim, interception claim, or damage claim attached to the launch.

Timeline
The Fattah-1 claim came after Israel opened Operation Rising Lion on June 13, 2025 and Iran began missile and drone retaliation. Conflict-level reporting from JINSA later summarized the June 13-24 fighting as involving roughly 574 Iranian ballistic missiles and 1,100 drones fired at Israel.
On June 18, Iranian state media said the IRGC used first-generation Fattah missiles in the eleventh phase of Operation True Promise III. AP reported that the Revolutionary Guard said Fattah-1 missiles had been fired toward Israel, while also noting expert skepticism about whether Iran's system should be treated as a true modern hypersonic weapon.

Role in the conflict
Within the conflict record, Fattah-1 is best described as an Iranian long-range strike weapon used in a retaliatory missile campaign. The reported June 18 firing was not a transfer, possession-only sighting, or battlefield capture; it was claimed operational use by the IRGC Aerospace Force against Israel.
The missile's public significance came partly from Iran's presentation of Fattah as a hypersonic or highly maneuverable ballistic missile. Iran Watch describes Fattah-1 as a missile Iran bills as hypersonic, but explains that its configuration is neither a hypersonic glider nor a hypersonic cruise missile; AP similarly reported that experts questioned the hypersonic characterization and the degree of maneuverability.

Battlefield effect and caveats
Iranian outlets and officials described the Fattah salvo as a penetration of Israeli air defenses. AP reported a more cautious picture: Israel said Iran had fired more than 400 missiles by that point, with more than 40 causing damage or casualties, and an Israeli analyst told AP that Fattah-1 had shown limited success.
This page therefore treats Fattah-1's June 18 use as source-backed Iranian claimed firing in the conflict, while leaving air-defense penetration, target damage, and hypersonic performance as attributed claims rather than independently established facts.
