What to do with Iran: First, Knock Out Several Coastal Military Installations. Here’s a list.

Iran maintains numerous naval and IRGC Navy facilities along its Persian Gulf, Gulf of Oman, and Caspian Sea coastlines, primarily for defense, patrol, and missile operations.wikipedia+1

Persian Gulf Facilities

These bases support regular navy (IRIN) and IRGC Navy operations, including submarines, frigates, and anti-ship missiles.

Bandar Abbas: Naval HQ with airbase, repair facilities, and underground missile sites; key for Strait of Hormuz control.tehrantimes+1
Bushehr: Major repair, storage, and IRGC 2nd Naval Region base.ifmat+1
Bandar Mahshahr: IRGC 3rd Naval Region base near Iraq border.wikipedia+1
Asaluyeh: IRGC 4th Naval Region headquarters.iranwire+1
Bandar Lengeh: IRGC 5th Naval Region and Imam Mohammad Bagher base, securing nearby islands.strausscenter+2
Khorramshahr: Repair and shipbuilding facilities.wikipedia
Kharg Island: Hovercraft fleet base northwest of Bushehr.wikipedia
Qeshm Island: IRGC naval base with quick Strait access.allsourceanalysis+1
Abu Musa Island: Small docking facility near airport.strausscenter+1
Sirri Island: Port facility opposite UAE.strausscenter+1
Larak Island: Small base near Bandar Abbas.strausscenter+1
Al-Farsiyah: Controlled naval facility.wikipedia+1
Halul Oil Platform: Naval outpost.strausscenter+1

Gulf of Oman Facilities

Strategic sites for extended maritime reach.

Bandar Beheshti (Chabahar): Port and base facilities; IRIN and IRGC Imam Ali independent base.ifmat+1
Jask: New major naval hub with specialized docks; small IRGC base at Strait mouth.tehrantimes+1
Sirik (Shaheed Rahbari base): IRGC base east of Hormuz for full Strait control.natofoundation

Caspian Sea Facilities

Limited to patrol boats and training.

Bandar-e Anzali: Primary base for Caspian fleet, including patrol boats and minesweepers.jamestown+1

Bandar Abbas stands out as the most critical facility, serving as the primary headquarters for both the Iranian Navy (IRIN) and IRGC Navy, with major ship deployments, submarines, airbase, and missile complexes essential for controlling the Strait of Hormuz. Bushehr ranks second due to its role as a key repair, storage, and IRGC 2nd Naval Region hub, supporting broader Gulf operations. Jask and Chabahar (Bandar Beheshti) are increasingly vital for extending power projection beyond the Strait into the Gulf of Oman.wikipedia+5

Strategic Importance Factors

Iran prioritizes bases for Strait of Hormuz dominance, asymmetric warfare, and missile deterrence, given 20% of global oil transits there.israel-alma+2

Hormuz Control: Bandar Abbas, Bandar Lengeh, Sirik, and islands like Abu Musa, Greater/Lesser Tunb host HQ, fast-attack craft, and anti-ship missiles for blockade threats.euronews+3
Force Projection: Jask’s new destroyer-capable port and Chabahar’s independent base enable blue-water ops.wikipedia+2
Underground Assets: Recent IRGC “missile cities” near Bandar Abbas and southern coasts house radar-evading boats and long-range missiles, deemed “impossible to destroy.”tehrantimes+1

Lesser Caspian Role

Bandar-e Anzali remains important for regional Caspian patrols but secondary to southern bases.wikipedia

Bandar Abbas hosts Iran’s primary submarine fleet, including three Russian-built Kilo-class (Tareq-class) diesel-electric submarines: Tareq (901), Noor (902), and Yunes (903), capable of firing torpedoes, mines, and cruise missiles. Key warships include frigates like Alvand-class (e.g., Alvand, Alborz), Moudge-class (Jamaran, Sahand), corvettes such as Bayandor-class, and support vessels like Bandar-class replenishment ships.nti+3

Submarines

These form the backbone of Iran’s subsurface capabilities at the base.

Kilo/Tareq-class: Tareq (S901), Noor (S902), Yunes (S903); ~3,000-ton diesel-electrics based permanently, with 2-3 operational; used for Hormuz patrols.maritime-executive+2
Ghadir-class midget subs: Several (e.g., Ghadir-942, Ghadir-955); coastal operations with torpedoes, mines, and missiles.reddit
Fateh-class: At least one (Fateh); indigenous coastal submarine.news.usni

Surface Warships

Frigates and auxiliaries rotate through, with recent sightings amid tensions.

IRGC Navy assets like high-speed missile boats and the Rais Ali Delvari warship are also unveiled/commissioned here, though primarily based elsewhere.tehrantimes+1
