Over the next five years, Iran will likely continue to develop its naval strategy and capabilities in a manner that is consistent with trends we have observed since the reorganization of 2007. Given Iran’s dependency on sea -based trade, its vast coastline and strategic position adjacent to the Strait of Hormuz, Tehran will continue to invest in both of its naval forces for the foreseeable future. Although Iran has come to appreciate the growing danger represented by ISIS forces in the Middle East, Iran’s leaders still perceive that threats to Iran will come primarily from the sea. As such, the IRGCN and IRIN will remain key components of Iran’s defense strategy.
