The Holland class Offshore Patrol Vessels are new patrol boats under construction for the Royal Netherlands Navy. They are designed to fulfil patrol and intervention tasks against lightly armed opponents, such as pirates and smugglers.

A contract between the Royal Dutch Navy and Damen Schelde Naval Shipbuilding in Vlissingen, the Netherlands was signed in 2007 for the construction of four vessels at a total cost of €467.8 million.[2]
The vessels resulted from the Dutch Ministry of Defence's Marinestudie.[3] The study proposes the sale of four existing Karel Doorman class frigates, and using the proceeds and savings of the sale to commission four dedicated patrol vessels, allow the building of a more capable Joint Support Ship to replace the AOR HNLMS Zuiderkruis, and reintroducing a mine-sweeping capability to the Dutch Navy.
The vessels are planned to be deployed to the Caribbean region and the North Sea.[2] They have the capability to carry out missions such as anti-piracy and blockade duties, and also can be used for emergency transport.[2]
The Holland Class' main armament is a 76mm Oto Melara Super Rapid gun with a firing rate of 120 rounds per minute and an effective range of 16 km.[2]
Secondary armament is provided by a 30mm Oto Melara Marlin WS, two 12.7mm Oto Melara Hitrole NTs and two 12.7mm M2HB machine guns.[2] All can be remotely operated.[2]
The ships are able to monitor 140 nm using a Thales Integrated Sensor and Communication Systems (ISCS), comprising a SeaMaster 400 air warning radar, a Watcher 100 active phased-array surface detection and tracking radar, a mine detection sonar and an infra-red Gatekeeper/electro-optical (EO) warning system.[2] The sensor systems are housed in an integrated mast, also provided by Thales, called the I-Mast 400.[4] Thales also built the satellite communications system for the ships.[5]
The Holland class is fitted with a combined electric or diesel (CODELOD) propulsion system built by Wärtsilä.[2] It comprises two Wärtsilä 12V26 diesel rated at 5,400 kW each, combined with electric motors that drive a controllable pitch propeller through two shafts.[2] Electric operation is used mainly for low-speed operation.[2]
Holland-class ships have a tonnage of 3,750 tons, are 108.4 metres (356 ft) in length, 16 metres (52 ft) in beam and have a draft of 4.55 metres (14.9 ft).[6] The ships have a speed of 21.5 knots and a range of 5000 nautical miles at 15 knots.[6] The ship's complement is 50 crew, as well as up to 40 people for duties such as helicopter or medical crew.[7]
The ships are built to a design that is intended to reduce the ability of radar to detect them,[2] as well improving seakeeping by locating the superstructure unusually far aft.[7] The ships are painted a new light blue-gray color, which supposedly has a better camouflage-effect then the standard light-grey paint used by other RNN-ships. The ships also carry two rigid-hulled inflatable boats and an NH-90 helicopter.[2]
The projected number of ships for the class is four; they are planned to be commissioned between 2011 and 2013.[2] On December 20, 2007 the contract was signed for four ships at a cost of around €467.8 million.[2] The ships will be named after Dutch provinces of historical maritime importance.
