Various series of rigid inflatable boat (RIB) are operated by naval forces of Iran. Based on a design by Italian Fabio Buzzi, they have been manufactured and modified in Iran.
The cooperation between FB Design and Iranians started in 1998, when frames and blueprints of patrol boat Levriero was purchased by Iran. [1] It is likely that Shahid Joulaee Marine Industries (subordinate to Marine Industries Organization) obtained a license to produce RIB-33SC and FB-55SC models domestically. [2] In 2005, American authorities questioned FB Design about their deals with Iran, effectively putting an end to the cooperation. [1] Iran has reportedly altered some original designs and manufactured similar modifications. [3]
According to 2015 edition of Jane's Fighting Ships , Iran is known to operate the following models and modifications of rigid inflatable boat:
The estimates for top speed of these vessels range between 60 knots (110 km/h) to 70 knots (130 km/h). [3] In addition to versions mentioned above, RIB 33 is in service in unknown numbers. [4]
According to H.I. Sutton, the Navy of the Islamic Revolutionary Guard Corps commissioned 32 RIBs into service in June 2020, some equipped with rocket launchers and the rest armed with machine guns. The vessels are used by the S.N.S.F., marines of the naval forces, likely for boarding operations. [5]
A rigid inflatable boat (RIB), also rigid-hull inflatable boat or rigid-hulled inflatable boat (RHIB), is a lightweight but high-performance and high-capacity boat constructed with a rigid hull bottom joined to side-forming air tubes that are inflated with air to a high pressure so as to give the sides resilient rigidity along the boat's topsides. The design is stable, light, fast and seaworthy. The inflated collar acts as a life jacket, ensuring that the vessel retains its buoyancy, even if the boat is taking on water. The RIB is an evolutionary development of the inflatable boat with a rubberized fabric bottom that is stiffened with flat boards within the collar to form the deck or floor of the boat.
LÉ Róisín (P51) is the lead ship of her class of offshore patrol vessel in the Irish Naval Service. Commissioned in 1999, the ship's primary mission is fisheries protection, search and rescue, and maritime protection operations, including vessel boardings. Róisín or Róisín Dubh, is often used as an allegory for Ireland. However, the original Róisín Dubh was a daughter of Red Hugh O’Neill, Earl of Tyrone in the late 16th century.
HMAS Armidale, named for the city of Armidale, New South Wales, is the lead ship of the Armidale class of patrol boats serving in the Royal Australian Navy (RAN).
The Defender-class boat, also called Response Boat–Small (RB-S) and Response Boat–Homeland Security (RB-HS), is a standard boat introduced by the United States Coast Guard in 2002. The boats serve a variety of missions, including search and rescue, port security and law enforcement duties and replaces a variety of smaller non-standard boats.
The Navy of the Islamic Revolutionary Guard Corps is the naval warfare service of the Islamic Revolutionary Guard Corps founded in 1985, and one of the two maritime forces of Iran, parallel to the conventional Islamic Republic of Iran Navy. The IRGC has been designated as a terrorist organization by the governments of Bahrain, Saudi Arabia and the United States. IRGC's Navy has steadily improved its capabilities to support unconventional warfare and defend Iran's offshore facilities, coastlines, and islands in the Persian Gulf.

HMAS Pirie, named for the city of Port Pirie, South Australia, is an Armidale-class patrol boat of the Royal Australian Navy (RAN).
The Nahang is an Iranian-made class of midget submarine designed for shallow water operations. Only one prototype of this class is known to be completed, although its characteristics have remained unclear.
HMAS Childers is an Armidale-class patrol boat of the Royal Australian Navy (RAN). Named for the towns of Childers, Queensland and Childers, Victoria, Childers is the only ship in the RAN to be named after two towns.
HMAS Launceston is an Armidale-class patrol boat of the Royal Australian Navy (RAN).
HMAS Maryborough, named after the city of Maryborough, Queensland, is one of fourteen Armidale-class patrol boats operated by the Royal Australian Navy (RAN).
HMAS Glenelg, named for the city of Glenelg, South Australia was an Armidale-class patrol boat of the Royal Australian Navy (RAN).
A rescue lifeboat is a boat rescue craft which is used to attend a vessel in distress, or its survivors, to rescue crew and passengers. It can be hand pulled, sail powered or powered by an engine. Lifeboats may be rigid, inflatable or rigid-inflatable combination-hulled vessels.
The Ashura is a class of fast patrol boat used by naval forces of Iran. It is a Boston Whaler type vessel based on a Watercraft UK design, and is manufactured domestically with hulls made of glass-reinforced plastic.
Murce is a class of fast patrol craft operated by naval forces of Iran.
MIL 55 is a class of fast inshore patrol craft operated by both naval forces of Iran.
MIL 40 is a class of fast inshore patrol craft operated by both naval forces of Iran.
Cougar is a class of fast patrol boat operated by the Navy of the Islamic Revolutionary Guard Corps of Iran.
Hendijan is a class of auxiliary ships operated by the Islamic Republic of Iran Navy. The first eight of this class were built by Dutch Damen Group, and the rest by Iran's Marine Industries Organization, Bandar Abbas. According to Jane's, ships of the class are tenders that are used for coastal surveillance and one of them is used as a training ship. IISS classifies all vessels as patrol boats.
A high-aspect-ratio twin-hull vessel refers to a certain design of catamaran vessels with small waterplane area. These vessels are built and used by the Islamic Revolutionary Guard Corps (IRGC) of Iran. Such design is considered relatively rare in military usage.
