Holm-class multi-purpose vessel
class of Danish multi-purpose vessel
The Holm class is a series of six multi-purpose vessels operated by the Royal Danish Navy. The vessels are named after small Danish islands or islets (in Danish, "holm" means islet), reflecting their primary role in coastal waters. Designed and built by Danish Yacht A/S in Skagen, they are known for their flexible design, which allows them to be adapted for different missions.
Design and roles
The Holm-class vessels are part of a larger Danish naval procurement program aimed at creating a modular fleet, which is achieved with the StanFlex modular mission payload system. They are built using a composite material known as a FRP (fibre-reinforced plastic) sandwich construction, which is also used in other Danish naval vessels like the Diana-class patrol vessels. This construction method reduces maintenance costs and gives the vessels a non-magnetic hull, a useful feature for mine countermeasures.
The vessels are divided into three groups of two, each designed for a specific primary role:
Hydrographic survey vessels (Birkhom and Fyrholm): These are equipped for hydrographic surveying and are used to map Danish waters.
Training vessels (Ertholm and Alholm): These are used for naval cadet training and carry a small complement of three crew members with lodging for up to ten trainees.
Mine countermeasures vessels (Hirsholm and Saltholm): These vessels can operate remote-controlled mine clearance drones or serve as support vessels. Their non-magnetic hull is critical for this mission.
This brief starts where responsible research should: with the source description of “Holm-class multi-purpose vessel” as class of Danish multi-purpose vessel. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as class of Danish multi-purpose vessel. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Dec 16, 2025. The linked authority identifier is Q12317111. None of the 1 selected statements returned an explicit reference.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
