US intelligence assessments report that Iran has increased its military precision in the Strait of Hormuz over the last few months. This shift resulted from satellite imagery and intelligence support provided by groups in China, which enabled Iran to launch precision strikes on US military bases and threaten regional shipping, based on accounts from 4 sources who described the reports to CNN.

The data provided by Chinese entities aided a transition in Iranian capabilities that has unfolded over several months. These assessments highlight that the external intelligence support is a primary factor in Iran's enhanced ability to conduct precise operations against American military assets in the Middle East.
