What is class 30.13, building of military ships and vessels?

Class 30.13 covers building of military ships and vessels. It was created as a new class in NACE Rev. 2.1, as paragraph 149 states, to separate military shipbuilding from civilian shipbuilding. Its explanatory note lists the vessels included, the factory conversion work included, and the exclusions to neighbouring classes. The class is statistical only, and it does not determine a code for a specific reader.

What does the note include?

The note includes building of military ships and vessels, such as combat ships equipped with various offensive and defensive weapons and with protective devices against shelling, and building of military floating structures. The examples in the note are aircraft carriers, amphibious warfare and assault ships, cruisers, destroyers, submarines, landing crafts, and tugs for transporting ammunition or mines. The list is introduced by the words for example, which means it illustrates the vessels covered rather than closing the list. The defining feature is the military character of the vessel, as the note presents it, together with the building activity itself. A vessel built for military use, with the equipment and protection the note describes, falls inside the description in general terms, whatever its size or propulsion.

The note also includes factory conversion of military ships, vessels and floating structures. Factory conversion is the rebuilding or conversion of an existing vessel in a factory setting, as distinct from repair and maintenance, which sits in division 33, and from specialised repair of civilian ships, which sits in class 33.15. The inclusion of factory conversion in the building class, rather than in the repair division, follows the manual’s general treatment of factory rebuilding, which is grouped with manufacture where the work amounts to building or rebuilding the vessel. The note must be read with the notes for the repair classes, because the boundary between conversion and repair is stated in both sets of notes, in general terms.

What does the note exclude?

The note excludes manufacture of weapons and ammunition, including torpedo tubes and torpedoes, to the class stated in the note for that work; factory overhaul of military ship and vessel engines to class 28.11; building of civilian ships and floating structures to class 30.11; and manufacture of inflatable boats or rafts for pleasure and sport to class 30.12. The exclusions separate the vessel from its weapons, its engines, and its civilian counterparts. The separation follows the manual’s grouping principle: weapons are manufactured in the fabricated metal products division, engines are manufactured in the machinery division, and civilian vessels are built in the neighbouring class in the same group. The vessel class covers the vessel itself, not the weapons it carries or the engines that propel it, in general terms.

The civilian exclusion is the most important boundary for reading the group. Group 30.1, building of ships and boats, now contains three classes: class 30.11 for civilian ships and floating structures, class 30.12 for pleasure and sporting boats, and class 30.13 for military ships and vessels. The three classes divide shipbuilding by the kind of vessel, and the notes for the three classes state the boundaries between them. The note for class 30.11 excludes building of military ships and vessels to class 30.13, and the note for class 30.12 excludes the same work to the same class. The boundary is therefore stated three times, from each side, and all three notes must be read before the group is described in general terms.

How is the class placed in the hierarchy?

| Level | Identifier | Title |

|---|---|---|

| Section | C | Manufacturing |

| Division | 30 | Manufacture of other transport equipment |

| Group | 30.1 | Building of ships and boats |

| Class | 30.13 | Building of military ships and vessels |

The table follows the detailed structure. The class sits in the shipbuilding group, beside the civilian and pleasure boat classes, and its number follows theirs in the order the manual lists the group. The table states the place of the class. The note states its content, and the correspondence table states how the old shipbuilding classes relate to the new classes, including the separation of military work that previously sat inside the broader shipbuilding classes.

What does a new class not decide?

Unless the manual states the source in section 4 or in an explanatory note, the old classes supplying a new class content are not stated in this cluster. If the manual gives no source, the guide states that and points to the correspondence table for the relationship recorded class by class. A source list invented from a title would misstate the revision and invite a reader to assume a one to one mapping the table does not support. This page guardrail states the limit directly, and the guide body repeats the limit in its own wording.

Where is a new class confirmed?

Start with the explanatory note for the class, then the correspondence table entry relating its content to the old classes, and finish by confirming the entry for the unit concerned with the national statistical institute or the business register holding the record.

Read the vessel examples with the factory conversion inclusion, follow the weapons, engine and civilian exclusions, and confirm the entry with the institute or register that holds it.
