Multiple outlets report that Russia is using a covert logistics route, dubbed the “Caspian Express,” to supply Iran. The reporting says the route supports Moscow’s efforts to arm Tehran while reducing reliance on more directly monitored pathways.

According to the articles, the Caspian Express takes advantage of geography and alternative transport corridors across the Caspian Sea and surrounding regions. This approach is described as enabling Russia and Iran to partially bypass U.S. maritime pressure in the Persian Gulf. The outlets emphasize that the arrangement is aimed at sustaining deliveries despite heightened scrutiny of shipments in the broader area.

Across the sources, the central points are consistent: the same named route is portrayed as the key mechanism, and the motive is presented as circumventing pressure and monitoring that affect conventional maritime shipping. While the articles differ in how they frame the operation’s secrecy, they converge on the claim that the route plays a backbone role in the Russia–Iran supply chain in the context of the Iran war.
