What it is Filled
The Holland class is a class of four ocean-going offshore patrol vessels built by Damen for the Royal Netherlands Navy, designed primarily for maritime surveillance, law enforcement support and security operations rather than high-intensity naval combat.
In scope
- Class identity, membership evidence and configuration baselines
- Hull envelope, propulsion modes and patrol endurance constraints
- Integrated mast, surveillance and command-system interfaces
- Shipboard interfaces for helicopters, boats and relief cargo
- Accommodation, mission suitability and readiness dependencies
- Class-specific maintenance evidence and operational restrictions
Out of scope
- Individual hull histories, positions and maintenance logs as standalone records
- The general offshore patrol vessel kind and unrelated Holland-named classes
- Internal designs of embarked helicopters, boats and installed weapons
- Royal Netherlands Navy organisation and personnel administration
- Mission plans, boarding procedures and rules governing use of force
- Replacement ship designs and acquisition programmes
Why it exists Filled
Enable an agent to recognise the Holland-class offshore patrol vessel design, assess a member vessel against its documented configuration, and identify the evidence and authority needed for proposed operations.
Distinguishing features Filled
- Require class-membership evidence linking the design to Holland P840, Zeeland P841, Friesland P842 or Groningen P843; a ship named Holland alone is insufficient. [Dutch Ministry of Defence](https://english.defensie.nl/documents/2022/04/01/ocean-going-patrol-vessel)
- Check the documented hull envelope: 108 m length, 16 m beam, 4.55 m draught and approximately 3,750 tonnes displacement; dimensions support identification but do not establish it alone. [Dutch Ministry of Defence](https://english.defensie.nl/documents/2022/04/01/ocean-going-patrol-vessel)
- Check for the integrated mast combining radar, cameras and communications, together with provision for an NH90 helicopter and two FRISC boats. [Dutch Ministry of Defence](https://www.defensie.nl/onderwerpen/m/materieel/schepen/patrouilleschepen)
- Confirm the documented emphasis on maritime security and humanitarian missions at lower levels of force; size and naval ownership do not establish frigate-equivalent combat capability. [Dutch Ministry of Defence](https://www.defensie.nl/onderwerpen/m/materieel/schepen/patrouilleschepen)
