HNLMS Friesland review on Dung Tran Military channel


Since time immemorial, the Netherlands has been a sea-faring nation with a strong dependence on the sea. Traditionally, therefore, the Royal Netherlands Navy sailed throughout the world to safeguard Dutch interests. In the current security situation, the demand for naval assets for deployment in crisis management operations is even greater than ever before.

During the recent twenty years, Dutch naval units have already proved their value many times over in peacekeeping and humanitarian operations.

Offshore patrol vessels have been an important part of the Royal Netherlands Navy. The duties of marine patrol forces include the tracing and rescue of people for drowning, enforcing shipping and maritime laws, fishery inspection, checking for violation of environmental regulations and combating illegal activities, such as drug trafficking.

HNLMS Friesland P842 is a Holland-class offshore patrol vessel operated by the Royal Netherlands Navy. This was one of four ships in a 46.8 million Euro contract between the Royal Netherlands Navy and Damen Schelde Naval Shipbuilding in Vlissingen in 2007. The ship entered service on January 22, 2013 and is named after the Dutch province of Friesland, located in the northern part of the country.

The vessel has a broad platform to provide stability in marine seas. Its stealthy design incorporates innovative techniques to reduce radar reflectivity. The body is built with thick steel, which has a lower tensile strength. It is heavier than the steel used for frigates and can resist the impact of small-calibre weapons.

The ship is painted a new light blue-gray color, which supposedly has a better camouflage-effect than the standard light-grey paint used by other Royal Netherlands Navy ships.

The hull is stretched and the bridge and superstructure are placed aftwards, to help optimise the seakeeping capabilities of the vessel. The vessel measure 108 meters in length and 18 meters in width with a displacement of approximately 3750 tons.

The stern area has a fully equipped hangar and flight deck for one medium-sized helicopter. To support interception operations, Two rigid-hulled inflatable boats and one NH-90 helicopter are boarded. The helicopter is equipped with homing torpedoes and a sensor system.

The sonar and radar on the helicopter allows it to make observations beyond the radar horizon of the OPV. The rigid-hulled inflatable boats will be launched and recovered via a slipway in the stern. The vessel accommodates 50 crew and up to 40 non-listed persons, such as helicopter crew and medical teams. Further some 100 evacuees can be boarded.

The Friesland is equipped with a combined electric or diesel propulsion system, two MAN 12V28/33 diesel engines of approx 5400 Kilowatt each. Alternatively electric propulsion can be chosen for low speed operations. Each propulsion system drives a Rolls-Royce controllable pitch propeller.

This propulsion system helps the patrol vessel reach a maximum speed of 21.5 knots and a range of 5,000 nautical miles at 15 knots.


This Patrol Vessel fulfil the operational requirements of the Royal Netherlands Navy for a robust platform with a limited weapon outfit, specifically designed for coastal patrol missions and maritime defence tasks in the territorial waters and EEZ of The Netherlands, The Netherlands Antilles and Aruba.

Her main armament consists is one 76 mm Oto-Melara Super Rapid gun with a firing rate of 120 rounds per minute and a maximum range of 16 km.

Secondary armament is provided by one rapid-fire 30 mm Oto Melara Marlin WS rapid cannon and two 12.7 mm Hitrole machine guns, all can be full remotely operated. Two water cannons are used for non-lethal protection and fire fighting.

In addition, there are six stations for hand-operated FN MAG 7.62mm machine guns.

Sensor and electronic system

The HNLMS Friesland and her sisters in the class are the first vessels of the Royal Netherlands Navy equipped with the Thales Integrated Sensor & Communication Systems, an integrated mast module which integrates practically all RF systems, radars as well as communication and optical sensors on board of the ship in one housing.

The ship is able to monitor to 250 km range air, missile and UAV targets and 70 km range surface targets. Together with this Integrated Sensor & Communication Systems these four advanced Patrol Vessels can face the threats and missions of today and tomorrow.

Operation history

During her activities, in November 2015 Friesland, and elements of the United States Coast Guard, cooperated in the seizure of $17 million of cocaine. The operation was part of Operation Caribbean Venture, under the overall command of the Royal Netherlands Navy. In March 2016, the ship shadowed the Russian destroyer Vice-Admiral Kulakov as the destroyer neared Dutch waters.

On September 20, 2018 Friesland intercepted a go-fast with its NH-90. The cargohold of the go-fast contained 900kg of cocaine. The passengers of the boat were delivered to the United States Coast Guard.
