Iran is apparently offering to enrich its large depleted uranium stocks back toward natural uranium while keeping its centrifuge numbers intact. Enriched uranium stocks can go up and down like a yo-yo, if centrifuges continue to operate. The offer is a non-starter
The Zvezda video also shows visual confirmation that Alabuga Start foreign female workers, primarily from Africa, are building Shahed 136 airframes. Building the airframe is a labor intensive job that can expose workers to hazardous chemicals and materials. This is particularly…


Another detail in the Zvezda video is a ready discussion of using child laborers to make Shahed 136 drones. According to a translation of the video: “No matter where you look, there are young people all around. Boys and girls work here and study here. In the college…


A key detail in the new Zvezda video is that Alabuga now claims to be producing nine-times more drones than it planned “at one time,” which can reasonably be interpreted as the first years of its franchise agreement with Iran to build Shahed 136 drones. During its contract with…

Impossible to make sense out of these pieces of “new” information. The headline is hyped up and the report is muddled. The only valuable information provided is perhaps the fact that Fordow was destroyed— not new information per se but helpful nonetheless given earlier confusing…
New U.S. assessment finds American strikes destroyed only one of three Iranian nuclear sites, five current and former U.S. officials familiar with the assessment tell @NBCNews. nbcnews.com/politics/natio…
Whoever wrote or leaked this is muddled, and the @NBCNews headline is hyped up nonsense. Esfahan is not an enrichment site. Two GBU-57’s were dropped on the Natanz underground enrichment plant. Could be that the original muddler is actually talking about the mountain complex at…
NEW RESEARCH MEMO: Significance of the Targeted Nuclear Scientists in the 12-Day War The June 2025 war between Israel and Iran, called the 12-Day War, saw the death of many Iranian nuclear scientists who participated in or are linked to Iran’s nuclear weapons program. Overall,…
Recent satellite imagery taken on July 9 shows only minimal activity at the Esfahan Nuclear Complex. At the three tunnel entrances to the mountain facility, which are believed to house at least some of the remaining enriched uranium stocks, the Iranians would have to dig through…

NEW REPORT: Post-Attack Assessment of Shahid Meysami Research Center The Shahid Meysami (or Meisami) research center is located west of Tehran, near Karaj, at coordinates 35.764667, 51.03245 and is part of Iran’s nuclear weaponization complex, according to the Israel Defense…

Last night, Russia attacked Ukraine with a record-breaking 728 Shahed-type drones from multiple directions. The launched drones include dummy drones meant to overwhelm Ukraine’s air defense, making it more likely for the Shaheds to reach their target.

Satellite imagery taken by Airbus shows multiple buildings at Iran’s Shahid Meysami research center were destroyed during Israel’s bombing campaign between the 15th and 16th of June, including a large hangar-type building constructed in 2021-2024, which reportedly housed “plastic…



An overview of activity at the Fordow Enrichment Plant, showing Iran's efforts to establish safe access to the multiple impact points at the underground plant for damage assessment, primarily the MOP impact points at the ventilation shafts, which appear temporarily covered as of…

Satellite imagery taken by @Maxar today show ongoing work at the MOP impact points of the Fordow Enrichment Plant and progress in clearing access to the eastern tunnel entrance portal. As of July 1, Iran has sufficiently cleared the surroundings of the eastern tunnel portal to…




Esfahan today June 30 2023 June 30, 2025 Maxar satellite imagery of the Esfahan, aka Isfahan, nuclear complex shows little sign of activity, including any construction or other movement. Iran does not appear to have yet commenced recovery operations, let alone begun to repair…
