The American strike on Fordow enrichment plant was astoundingly accurate.  

The U.S. military successfully precision-hit the two weakest points in the mountain over the underground Fordow halls.  They happened to be perpendicular to each other at two ends of underground halls, channeling the blasts down the halls at depth.  The video below shows the location of the MOP holes relative to the underground facility.  One set overlays well with the ventilation shaft work being performed in 2009 and another with service related structures that lay above the cascade hall.

A full battle-damage assessment report will come soon!

NEW DEEP DIVE: Taleghan 2: Pre- and Post Strike Assessment – Everything there is to know about the building Israel attacked and its nuclear weapons connection, with plenty of imagery analysis



1/ isis-online.org/isis-reports/d…Image
The Institute was able to confirm with a Western government that there is evidence that nuclear weapons related activities recently took place at Taleghan 2. Based on @Axios reporting and the Institute’s understanding, it appears likely that Taleghan 2 contained equipment to make high purity PETN plastic explosives. 2/
These explosives, which are moldable, were used during the Amad Plan in the channels of the shock wave generators, a type of multipoint initiation system used to detonate the main high explosive charge in a nuclear weapon. 3/

NEW IMAGERY UPDATE: Rapid cleanup underway at Iran’s attacked site at Parchin Military Complex, including Taleghan 2 site, former Amad site but also associated with nuclear-related equipment and/or activities recently. Within ten days after the attack, Iran covered the demolished building with a makeshift structure and erected a visual security screen to shield the immediate area from outside views. 1/Image
Very interesting in light of reporting that nuclear weapons related equipment was present at Taleghan 2 recently: The solid visual security screen supported by a wire frame shields the demolished building and the possibly sensitive equipment debris pile from being viewed by anyone passing by or involved in cleanup activities outside the immediate area (overhead observation excluded, but that is limited to the top layer of the pile and available imagery not of sufficient resolution to pick out details) 2/
The November 6 image is the only high resolution image with the visual security screen present. This schematic shows more clearly what is difficult to see from the overhead perspective but can be drawn from shadows. 3/ Image

NEW INSTITUTE REPORT: The Islamic Republic’s Work on Pharmaceutical Based Agents

(Just in time for this week’s @OPCW meeting, #CSP29)

1/isis-online.org/isis-reports/d…
@OPCW The rise of the widespread use of easy-to-operate drones in the Middle East has increased the risk of Iran or its proxies using lethal and incapacitating pharmaceutical-based agents (PBAs), particularly fentanyl and medetomidine. 2/
@OPCW Our new report analyzes Iran's work on PBAs and indications of their weaponization by assessing technical and scientific publications from entities related to Iran’s military apparatus, providing a comprehensive survey of the research done from 2005 until 2023. 3/

NEW Breakout Numbers: Iran could have enough weapon-grade uranium for its first nuclear weapon (25 kg) in 12 days, using 60 percent enriched uranium stock. In another twelve days it could produce a second quantity. Adding in the use of 20 % stock leads to five within one month.1/
Our 12 days estimate is in line with the US govt estimate made public yesterday. This is the first public breakout estimate from the US in a long time and the first to acknowledge significantly less than a month. 2/
Breakout details: In parallel to enriching 60 percent to 90 percent WGU, after a set up time, Iran could use its 20 percent enriched uranium to produce three more quantities by the end of the first month after breakout starts. 3/

NEW: We have identified the likely location of Iran's new Narigan mine at 31.72379, 55.68888. The location is near the village of Narigan & consistent with the reported 35 km distance from Bafq. It is also 90 km south of Iran's only currently operating uranium mine at Saghand. 1/ Image
The Narigan mine is just getting started. This Maxar image from Oct 23, 2022 shows mining preparations: the large spoil pile indicates substantial "overburden removal" in the area. Once mining is fully underway, ore will be moved to a segregation pad for sorting and blending. 2/ Image
An earlier 2020 image shows minimal ground scraping and road grading in the area. 3/ Image

A long thread covering the highlights of our new Comprehensive Survey of Iran's Advanced Centrifuges:
In the last 2 yrs, Iran has accelerated its deployment of advanced centrifuges, following a lull of 3 yrs created by the JCPOA. Iran has demonstrated its commitment to replace the IR-1 centrifuge with advanced centrifuges, which can produce considerably more enriched uranium. 1/
This graph shows the number of advanced centrifuges deployed from 2011 to today, w/ a projection for early to mid-2022 based on Iran’s announced plans. The total number of installed advanced centrifuges has been increasing rapidly as Iran continues to violate the JCPOA. 2/
