Shahab-6 (Toqyān) is the designation of an alleged and possibly fictional Iranian long-range ballistic missile project alleged to exist by Israeli sources, and supposed to be an extension of the Shahab ("meteor") series of missiles, and first reported to the world by Israeli prime minister Benjamin Netanyahu in 1997. To this date, no public evidence exists of such a missile series. While Shahab-1 to -3 missiles have been produced and deployed, Iran has officially denied the existence of any further military missile projects, acknowledging only a program to develop a satellite launch vehicle. There is also no publicly known evidence that the Shahab-4, Shahab-5, and Shahab-6 missiles were ever planned and no proof that they exist, since being first alleged by intelligence sources in the 1990s.
Shahab is the name of a class of Iranian missiles, service time of 1988–present, of which three variants are confirmed: Shahab-1, Shahab-2, Shahab-3, while the Shahab-4, Shahab-5, Shahab-6 (Toqyān) were alleged to exist by Western and Israeli sources in the early 1990s but these allegations were not proven.
