Holland-class

Summary

Description

The Holland-class ocean-going patrol vessels comprise four ships commissioned by the Royal Netherlands Navy. These vessels were born out of a need to engage in patrol and intervention tasks against lightly armed opponents, such as pirates and smugglers, while having superior electronic and radar surveillance capabilities. These capabilities are particularly useful for military stabilization and security roles without escalating to full-scale warfare. Notably, these ships are constructed without sonar or long-range weapons but leverage the sophisticated Thales integrated mast system, allowing comprehensive communication and surveillance, including two four-faced phased arrays for air and surface search.

The origin of the Holland-class vessels traces back to a contract signed in 2007 between the Royal Netherlands Navy and Damen Schelde Naval Shipbuilding in Vlissingen, the Netherlands. The contract, totaling €467.8 million, was part of the Dutch Ministry of Defence's Marinestudie, proposing the replacement of four existing Karel Doorman-class frigates. The proceeds from the frigates' sale went toward commissioning these new patrol vessels, a joint support ship, and reintroducing mine-sweeping capabilities. These vessels are equipped for global deployment including regions like the Caribbean, the South China Sea, and the North Sea, providing versatility in their operations.

Designed to be resilient against lightly armed threats, the Holland-class vessels' main armament is the Oto Melara Super Rapid gun, supplemented by secondary armaments, including Oto Melara Marlin and Hitrole NT autocannons, M2HB machine guns, water cannons for non-lethal action, and stations for FN MAG-7.62 mm machine guns. For rapid interception, the vessels carry two Fast Raiding Interception Special forces Crafts capable of over 40 knots and a Combat Management System for efficient operational control.

Their sensor suite is impressive and expansive; a comprehensive Thales Integrated Sensor and Communication Systems provide a vast surveillance range for air, missile, UAV, and surface targets. The heart of this system is the I-Mast 400, supplemented by advanced radar systems and data links, providing the ability to monitor and track various threats and objects even at significant distances.

Propulsion for the Holland-class is provided by a combined electric or diesel (CODELOD) system, which allows for both high power and efficient, low-speed operations. The electric motor, combined with the main diesel engine, turns the controllable-pitch propeller, demonstrating a versatile and adaptable power system for various duties.

The design of these vessels includes stealth features to diminish radar detection and an advanced superstructure placement for better seakeeping. The ships are finished with a unique camouflage-paint and are equipped with a hangar and flight deck suitable for an NH-90 helicopter and enhanced communication infrastructure to better suit roles involving asymmetric warfare.
