The country’s IRGC-linked Tasnim News Agency reports that two “Fateh class” ballistic missiles were recently launched from Shahid Mahdavi, which the Iranian Navy took delivery of in March 2023 after it was converted from a state-owned and operated container ship known as the Sarvin.

The War Zone reports,

Iran’s Islamic Revolution Guards Corps (IRGC) has fired two ballistic missiles from launchers disguised as standard shipping containers that were hosted aboard one of its sea base-like vessels. This particular combination, which has not been seen to date, greatly expands the reach with which those weapons could be used to strike potential targets by surprise, especially given that shipping containers can be embarked on any vessel that has the space to accommodate them.

Iran’s liberal transfer of technology to proxies and the inherent deniability of containerized missile systems aboard nondescript vessels opens a number of unpleasant possibilities.

Launching from the sea complicates defenses because it means new potential threat axes.

This potentially threatens the US as well as our allies. Defenses designed to intercept ICBMs don’t necessarily work against shorter ranged ballistic missiles or cruise missiles. Those destroyers intercepting ballistic missiles over the Red Sea are not patrolling off the US coast ready to intercept missiles aimed at US cities.
