Iran has begun building a sub-tattoo structure at the Purdue nuclear site, according to satellite footage released this morning (Friday) by the Associated Press.

According to satellite imagery, construction on the nuclear site began as early as September. It can be seen that the construction is taking place in the northwest corner of the facility, which is located near the city of Qom. In the photos taken on November 4 and December 11, it appears that an excavation base was built at the site for a building with dozens of columns that could be used to support buildings being built in areas experiencing frequent earthquakes.

Jeffrey Lewis, an expert at the James Martin Center for the Study of the Convention on the Non-Proliferation of Nuclear Weapons at the Monterey Institute for International Relations, told the EP that “any change in this site will be carefully examined as a sign of Iran’s nuclear program.”

The construction site being built is located in an underground facility in Purdue, and was built deep inside a mountain to protect it from airstrikes. It is located next to other buildings in the facility where they are working for the purpose of research and development, one of which is the Iranian National Center for Vacuum Technology, an area considered critical for Tehran’s desire to enrich uranium.
But not only research buildings are in the facility, but also anti-aircraft guns and other fortifications designed to protect the site. It is the size of a football field, large enough to hold 3,000 centrifuges but small enough to make American officials suspect Iran’s real intentions after the site was unveiled in 2009.
