Under the belief that Israel and the United States were planning to attack its nuclear program, Iran conducted the Great Prophet III missile test and war games exercise.

The nuclear program of Iran consists of an extensive infrastructure of research sites, uranium mines, research reactors, uranium processing facilities, enrichment sites, the Bushehr Nuclear Power Plant—the country’s sole operational power reactor, currently expanding with two additional units—and the developing Darkhovin Nuclear Power Plant in Khuzestan. The program’s research capabilities are anchored by several facilities, most notably the Tehran Research Reactor and the heavy water reactor at Khondab. Its uranium processing infrastructure is centered in Isfahan, which serves as a hub for conversion and fuel fabrication, while primary enrichment activities are conducted at Natanz, Fordow, and within the Isfahan complex.
