A patrol boat is a relatively small naval vessel generally designed for coastal defence, border security, or law enforcement. There are many designs for patrol boats, and they generally range in size. They may be operated by a nation's navy, coast guard, police, or customs, and may be intended for marine, estuarine, or river environments.
The River class is a class of offshore patrol vessels built primarily for the Royal Navy of the United Kingdom. A total of nine were built for the Royal Navy (RN), four Batch 1 and five Batch 2. One Batch 1 (HMS Clyde), which was the Falklands guard ship, was decommissioned and transferred at the end of its lease to the Royal Bahrain Naval Force.
The M242 Bushmaster chain gun is a 25 mm (25×137mm) single-barrel chain-driven autocannon. It is used extensively by the U.S. military, such as in the Bradley fighting vehicle, as well as by other NATO members and some other nations in ground combat vehicles and various watercraft. Hughes Helicopters in Culver City, California, was the original designer and manufacturer. As of 2019, Northrop Grumman Innovation Systems produces the gun.
The OTO Melara 76 mm gun, marketed as the OTO 76/62 Gun Mount, is a naval autocannon built and designed by the Italian defence company OTO Melara. It is based on the OTO Melara 76/62C and evolved toward 76/62 SR and 76/62 Strales.
The Mk44 Bushmaster II is a 30 mm chain gun manufactured by Northrop Grumman. It is a derivative of the 25 mm M242 Bushmaster, and uses 70% of the same parts as the M242 while increasing the firepower by as much as 50% with the 20% increase in caliber size. The barrel is chromium-plated for extended life. The gun uses standard GAU-8 Avenger ammunition that is available in API, HEI and APFSDS-T variants.
DARDO originally known as Breda Type-70, also marketed as the OTO Twin 40L70 Compact, is a close-in weapon system (CIWS) built by the Italian companies Breda and Oto Melara. It is composed of two Breda-built Bofors 40 mm firing high explosive (HE) shells, a fire-control radar and a fire-control system. It is the last of a long series of Italian anti-aircraft weapons derived from the Swedish Bofors 40 mm autocannons.
A remote controlled weapon station (RCWS), remotely operated weapon system (ROWS), or remote weapon system (RWS), is a remotely operated light or medium-caliber weapon system, often equipped with a fire-control system, that can be installed on a ground combat vehicle or sea- and air-based combat platform.
The Kedah-class offshore patrol vessels of the Royal Malaysian Navy (RMN) are six ships based on the MEKO 100 design by Blohm + Voss. Originally, a total of 27 ships were planned, but due to programme delays and overruns, only six were eventually ordered. Their construction began in the early 2000s, and by 2009, all six were in active service. The six vessels are named after Malaysian states.
The Typhoon is a type of remote weapon station manufactured by Rafael Advanced Defense Systems of Israel, and it shares similar design principles and common technologies with Samson Remote Controlled Weapon Station, a land-based system manufactured by the same developer. Like Samson RCWS, Typhoon is also multi-configurable.
The Viana do Castelo class is a class of offshore patrol vessels planned by and for the Portuguese Navy, as a result of the NPO2000 Project, that are being constructed in the West Sea Shipyard.
The Holland-class ocean-going patrol vessels are a class of four ocean-going patrol vessels constructed for the Royal Netherlands Navy. They are designed to fulfill patrol and intervention tasks against lightly armed opponents, such as pirates and smugglers, but have much higher level electronic and radar surveillance capabilities which are used for military stabilization and security roles, short of outright war. Without sonar or long range weapons, they utilize the surveillance capabilities of the Thales integrated mast, which integrates communication systems and two four-faced phased arrays for air and surface search.
The Minerva class is a series of corvettes of the Italian Navy. They were built in two batches of four units during the 1980s and 1990s. The ships have fairly good speed and armament, including a 76 mm general-purpose gun, but, due to their emphasis on anti-submarine warfare, they lack anti-ship missile capabilities. These units are designed to operate in coastal areas. Their main missions include sea policing, patrol, fisheries protection, and naval commando training. Four ships of this class are now active with Bangladesh Coast Guard as offshore patrol vessels (OPVs).
The Knud Rasmussen class is a class of offshore patrol vessels operating in the Royal Danish Navy from 2008. Built to replace the Agdlek-class cutters on a one-for-one basis, the Knud Rasmussen-class vessels are significantly larger, enabling patrols further offshore.
The 30mm DS30M Mark 2 is a ship-protection system made by MSI-Defence Systems consisting of a 30mm Mark 44 Bushmaster II cannon on an automated mount. It was designed to defend Royal Navy frigates from fast inshore attack craft armed with short-range missiles, rocket-propelled grenades, machine guns, or explosives.
The Arafura class is a class of offshore patrol vessels being built for the Royal Australian Navy (RAN). Initially proposed in the 2009 Defence White Paper and marked as procurement project SEA 1180, it was originally planned that 20 Offshore Combatant Vessels (OCV) would replace 26 vessels across four separate ship classes: the Armidale-class patrol boats, the Huon-class minehunters, the Leeuwin-class survey vessels, and the Paluma-class survey motor launches. Although having a common design, the ships would use a modular mission payload system to fulfill specific roles; primarily border patrol, mine warfare, and hydrographic survey. The 2013 Defence White Paper committed to the OCV project as a long-term goal, but opted in the short term for an accelerated procurement of an existing design to replace the Armidales, and life-extension refits for the other types. This resulted in the Offshore Patrol Vessel (OPV) project and the number of vessels reduced to 12. However, this was further increased to 14 when 2 further Mine Counter Measures variants were proposed under SEA 1905.
The Oerlikon KBA is a 25 mm (25×137mm) autocannon, developed as a close range multipurpose weapon for the mechanised battlefield, originally made by Oerlikon and currently produced in Rheinmetall Italia S.p.A. facilities. It is a positively locked breech, gas and recoil operated cannon with a rotating bolt head and a dual-belt selective feed system taking a 25mm NATO cartridge. The rate of fire in burst mode is up to 600 rounds per minute but it can be adjusted electronically and reduced to single shot or a selectable range from 100 up to 175 rounds per minute.
The Musytari class is a class of two offshore patrol vessels of the Royal Malaysian Navy in service from 1980s to 2006. They were then handed over to the Malaysian Maritime Enforcement Agency / Malaysia Coast Guard in June 2006, renamed and known as the Langkawi class.
The Tun Fatimah class is a series of offshore patrol vessels (OPVs) built by the Malaysian company THHE-Destini with the assistance of Damen company from the Netherlands based on the design of the Damen 1800-class OPV vessel. THHE-Destini is a joint venture between two local company which is THHE and the Bagan Datuk-class patrol vessel builder, Destini Berhad. The class is also known as the Damen 1800-class offshore patrol vessel and the class changed names after the first ship of the class, KM Tun Fatimah. A total of three ships of this class are planned to be built.
Destini Berhad is a Malaysian company that is involved in heavy industry, defence and oil and gas. This company was formed in 1991 under the name of Satang Jaya Sdn Bhd. At the beginning, this company involved in the business as a supplier of aviation tools and spare parts from Original Equipment Manufacturers (OEM) to Malaysian government especially for Malaysian Armed Forces.

The Inlay-class offshore patrol vessel is a class of offshore patrol vessel (OPV) operated by the Myanmar Navy. The lead ship of the class is UMS Inlay. UMS Inlay was built at Thanlyin Naval Dockyard near Yangon with the help of technical assistance and equipment provided by Singapore-based companies. Launched in late November 2015, Inlay was commissioned in December 2017. Subsequently, Inma was commissioned in December 2021.
