HMS M1 M-Class Submarine Monitor Building Blocks

Recreate an unusual chapter of early 20th-century naval engineering with the HMS M1 M-Class Submarine Monitor Building Blocks. Designed and authorized by ModelFunShipyard, this 148-piece model is inspired by HMS M1, an experimental British submarine monitor concept developed during the First World War.

Unlike conventional submarines of the period, HMS M1 was conceived around the idea of combining underwater concealment with the heavy firepower of a surface monitor. Its distinctive large-caliber deck gun gives the vessel an instantly recognizable silhouette and makes the finished model a unique addition to historic naval collections.

An Unusual Submarine Monitor Concept

HMS M1 was designed as a submarine capable of approaching targets while submerged before using heavy surface firepower, offering a very different tactical concept from conventional submarines.

Inspired by First World War Naval Warfare

The original concept was intended to provide support during coastal bombardment operations, using the submarine’s ability to submerge as a means of approaching hostile areas with greater concealment.

Distinctive Heavy Deck Gun

The model captures the defining feature of the M-class design: its exceptionally large forward-mounted gun, which immediately separates HMS M1 from more traditional submarine profiles.

Compact Naval Display Model

With 148 pieces, the model offers a relatively quick building experience while still capturing the unusual proportions and historic character of this experimental warship.

From the Designer

ModelFunShipyard created this model to recreate the distinctive HMS M1 submarine monitor, focusing on the unusual combination of submarine concealment and heavy naval artillery that made the design stand out from conventional warships of its era.

A Unique Addition to Historic Naval Collections

Its unconventional design, First World War background, and recognizable deck-mounted gun make HMS M1 an interesting display piece for submarine enthusiasts, naval history collectors, and builders interested in experimental military vessels.
