Iran’s Naval Forces

The Iranian fleet is divided between the regular Islamic Republic of Iran Navy (IRIN), and the Iranian Revolutionary Guard Corps Naval Forces (IRGCNF). 18,000 sailors are enlisted in the regular navy, whilst the IRGCNF is comprised of 20,000 sailors and 5,000 marines.21 Iran has seven frigates and 32 fast-attack missile craft designed for green-water service which form the core of its surface fleet, all armed with the C-802 Noor long-range anti-ship missile.22 Iran has also invested in a large flotilla of small craft, ranging from offshore patrol boats to armed motorboats and dhows, intended for coastal service and for mounting swarm attacks in the Strait of Hormuz. Iran has a squadron of five minelayers, as well as several mine countermeasures vessels, which can be supplemented by its small craft in laying naval mines in the Strait.23 The Iranian submarine service is made up of a total of 29 submarines, divided between the IRIN and IRGCNF.24 Five of these submarines are capable of operating in blue water, and the rest appear to be designed for service in the Persian Gulf. A number of ships and submarines are currently under construction, although information about these vessels remains limited.

The IRGCNF is tasked primarily with defending the Iranian coast and for interdicting shipping in the Strait of Hormuz. IRGCNF controls Iran’s asymmetric capability force, including its small attack craft, suicide vessels, and batteries of relatively short-ranged anti-ship missiles. IRGCNF bases are located in the Persian Gulf, and as its focus is limited to Iran’s littoral zone, its vessels are constrained by a smaller operating radius than the regular surface fleet. The IRGCNF also commands over 17 Qadir­-class and Nahang–class midget submarines, the majority of Iran’s submarine force, which are designed for service exclusively in the Persian Gulf.

By contrast, the IRIN controls Iran’s blue-water capabilities. Although both the IRIN and IRGCNF share responsibility for protecting the Iranian coast in the Persian Gulf and the Caspian Sea, since 2011 the IRIN has begun to focus on expanding Iran’s regional maritime reach. In the event of a conflict with the United States or with Iran’s Gulf Cooperation Council (GCC) rivals, the main Iranian effort would likely be focused on closing the Strait of Hormuz and on attacking shipping in the Persian Gulf. Most of these operations would fall under the responsibility of the IRGCNF, which has the capability to interdict shipping through the Strait with its small vessels and missile batteries. The Bab-el-Mandeb Strait, however, falls out of the operating range of most of the IRGCNF’s vessels, and so any operations in the Red Sea or the upper Gulf of Aden would be undertaken by the IRIN.
