By 1976 the 6 major ports of Bandar-e Abbas, Bandar-e Shahpur, Chah Bahar (known as Bandar-e Beheshti after the 1979 Revolution), Bushehr, Abadan, and Khorramshahr had a capacity of 12 million tons, with expansion projects underway. By late 1977, unloading delays, which had caused serious issues in commerical transport through Iran's ports, were no longer a problem. As a result of war damage, the ports of Abadan and Khorramshahr were closed in 1980, leaving the other four main ports and twelve minor ports in operation.
By 1977 the bulk of the fleet was shifted from Khorramshahr to the newly completed base at Bandar-e Abbas, which became the new naval headquarters. Bushehr was the other main base. Smaller facilities were located at Khorramshahr, Khark Island, and Bandar-e Khomeini (formerly known as Bandar-e Shahpur). Bandar-e Anzali (formerly known as Bandar-e Pahlavi) was the home of the small Caspian fleet. Other facilities were being constructed, such as Bandar Beheshti (formerly Chah Bahar), construction of which had begun prior to 1979.
During the Iran-Iraq War, Iranian naval continued to use many of the existing naval facilities, expanding during the conflict and into the Tanker War mainly to offshore oil platforms, used as improvised forward operating bases. By the end of the conflict, international particiaption, primarily by the United States, had led to main of Iran's purpose built naval facilities and improvised bases suffering damage. Extensive repairs and expansions continued to be conduct throughout the 1990s and into the early 2000s.http://www.globalsecurity.org/military/world/iran/navy-base.htmChah Bahar (Bandar Beheshti)
Construction of the port facilities at Chah Bahar was started prior to the Iranian Revolution in 1979. However, the facilities had still not been completed due to the Iran-Iraq War and other regional conflict even by 1987. The facilities were renamed Bandar-e Beheshti after the Iranian Revolution.
Bandar Beheshti, located on the Gulf of Oman in the Arabian Sea, has since become an important port facility, designated by the Iranian authorities as a Free Trade Zone, in addition to being another important naval facility.
Iran's Bandar-e Abbas is a naval facility on the Persian Gulf along the Straights of Hormuz. Constructed during the late 1970s, Bandar-e Abbas quickly became the headquarters for both the Islamic Republic of Iran Navy and the Iranian Revolutionary Guard Corps Navy. The headquarters of the Imperial Iranian Navy had already been moved from Khorramshahr (where Iran still maintained a naval base) to Bandar-e Abbas in 1977.
By 2008 it had become the home to Iran's Shahid Darvishi shipbuilding concern (a member of the Maritime Industries Group of the state run Defense Industries Organization) and its submarine force. Bandar-e Abbas, likely to be an important target in any conflict Iran might find itself in, has been observed to be heavily defended, with numerous batteries of shore based surface-to-surface missiles emplaced in the surrounding area.
Bandar-e Abbas is also home to a naval heliport and airfield, home to a navy patrol squadron with F-27 and Da-20 aircraft, and an ASW squadron with SH-3D and AB-212AS helicopters. As of 2008 it was also home to the Navy's P-3F fleet. The Iranian Revolutionary Guard Corps Navy also operated from the field, flying Mi-17 helicopters.http://www.globalsecurity.org/military/world/iran/abbas-nb.htmBandar-e Anzali
Bandar-e Anzali (also written Bandar-e Anzelli) has been and continues to be the home of Iran small Caspian fleet, which prior to 1990 consisted of only a few patrol boats and a minesweeper. Previously named Bandar-e Pahlavi, it was renamed following the Iranian Revolution in 1979, it is Iran's most important Caspian port.
In 2008 Iran announced a proposal to further develop the Anzali port facilities, as well as creating a Free Trade and Industrial Zone. Bandar-e Anzali is also home to Shahid Tamiidi Industries, a member of the Maritime Industries Group of the state run Defense Industries Organization.http://www.globalsecurity.org/military/world/iran/anzali.htmBushehr
Iran's Bandar-e Bushehr naval facility is located on the Persian Gulf. It is one of the Iranian Navy's most important repair facility and is also home to large storage facilities. Bushehr is home to a branch of the Iran Navy Technical Supply Center and is home to various research and development programs. Bushehr is also a common staging ground for naval maneuvers in the Persian Gulf.
The city of Bushehr also houses a large nuclear reactor and a large air base.http://www.globalsecurity.org/military/world/iran/bushehr-nb.htmKharg Island
Kharg Island (sometimes referred to as Khark Island) is located in the northeastern Persian Gulf, 16 miles (25 km) off the coast of Iran and 300 miles (483 km) north of the Strait of Hormuz. Once the world's largest offshore crude oil terminal and the principal sea terminal for Iranian oil, the Kharg Island facilities served as an important base for the Imperial Iranian Navy prior to 1979 and to the Islamic Republic of Iran Navy and Iranian Revolutionary Guard Naval Corps after 1979. Kharg Island had been home to Iran's massive hovercraft fleet, the site of exercises for hovercraft tactics, and the launching pad for the force that occupied Abu Musa and Tunbs Islands in the late 1970s.
The Kharg Island facilities were effectively out of commission in the fall of 1986. Heavy bombing of the Kharg Island facilities from 1982 through 1986 by the air forces of the government of Iraq during the Iran-Iraq War had all but destroyed most of the terminal facilities. Kharg Island was situated in the middle of the Darius Oilfield, also destroyed by the intensive bombing. Even with the damage Kharg Island continued to be an important base for IRGCN operations during the Tanker War, mostly because of its prime position at the head of the Persian Gulf.
Repair to all facilities had been very slow, even after the war ended in 1988, due to continued hostile intentions by the Iraqi Government and the Gulf War or 1990-1991. Kharg Island was repaired and remained operational through 2008. Its strategic and economic importance has seen the facilities not only repaired, but moves made to improve and expand.http://www.globalsecurity.org/military/world/iran/kharg.htmKhorramshahr
The Iranian navy base at Khorramshahr was home to the headquarters of the Imperial Iranian Navy prior to 1977. At that time it was moved, with the bulk of the fleet, to the new headquarters at Bandar-e Abbas. Khorramshahr retained major ship repair and shipbuilding facilities which made it an attractive target during the Iran-Iraq War. Khorramshahr sustained sufficient damage to warrant its closure in 1980. Khorramshahr was in fact occupied by Iraq during 1980, to be liberated by Iranian forces two years later.
Repaired following the conflict and subsequently reopened as both a port and naval facility, Khorramshahr remains an important repair and shipbuilding facility for the Iranian navy. In addition to the military controlled Naval Ship Repair Yard, Khorramshahr is also home to Shahid Mousavi Industries, a member of the Maritime Industries Group of the state run Defense Industries Organization. Khorramshahr is also home to Iran's University of Marine Science and Techonlogy, an organization that has been very active in Iran's domestic submarine programs and other naval developments.http://www.globalsecurity.org/military/world/iran/Khorramshahr.htmNoshahr
Not technically a navy base, the city of Noshahr in Iran is home to the Imam Khomeini University for Naval Sciences, Iran's naval staff college. Noshahr is along the Caspian, complementing Bandar-e Anzali, the Iranian Navy's primary training base.http://www.globalsecurity.org/military/world/iran/noshahr.htm
