4 new structures surrounded by high earth berms for blast deflection are currently in construction in Parchin Complex - Plan 6.
Parchin complex is involved in R&D, production of chemical weapons, laser technology for Uranium Enrichment, as well as high-explosive testing for nuclear weapons.
This comes after the completion of the nearby extension in November 2020, comprising a dozen new buildings surrounded by High and Thick concrete blast walls. This extensive construction activity since 2018 is probably related to Iran Ballistic Missile Program, however, it cannot be ruled out that a part of it could be contributing to other activities restricted or monitored by the JCPOA.
