461:, and common sense dictates that the most famous and/or numerically significant subtype(s) should be split off first. Rather than creating separate articles for each subtype of a vehicle, it is common to create a combined article on all variants, treating them in more detail than the summary "Variants" section in the major article about a type (eg.

articles about vehicles that have not yet been built are generally discouraged unless reliable sources provide strong evidence about the project's notability. Future vehicles, including those that exist as prototypes but have not entered serial production, may support an article if they have been the

Articles should not be fragmented, with each split lowering the level of notability. While a type may be notable, it is not normally advisable to have a separate article for subtypes, and it is often the case that despite the parent type being manifestly notable, a derivative article may not be.
450:
The creation of articles on subtypes is almost always for pragmatic reasons. In each of the above examples, a separate article may become practical if the parent article grows to the point where it may be split to a new article, and notability can be demonstrated using the criteria below. This

Note that the line between "type", "subtype", and "unique" is not necessarily clear-cut; and has occasionally been deliberately blurred in one direction or the other for political and/or marketing reasons. In general, Knowledge (XXG) editors should be guided by distinctions provided in reliable

In those situations where the type does not fit the established criteria for notability, it may be better to feature material about it in an article about a closely-related design or (if none exist) about the manufacturer rather than creating a separate article for that aircraft.
577:
Note that an individual vehicle may be notable as a unique example of a distinct "type" under the criteria set out above. In this case, it is the "type" that is significant, not its notability as an individual vehicle, and this will be considered in the naming of the article.
468:
Some subtypes are clearly distinct from the immediate parent type and should have their own articles even if the main article does not have to be split. The most obvious case for a "clearly distinct" subtype is when the vehicle is used for a different role, such as the
