Mark (designation)

From Wikipedia, the free encyclopedia
Jump to: navigation, search

The word mark, followed by number, is a method of designating a version of a product. The kind of products that use this convention vary widely in complexity. The concept shares some similarities with both the "Type (designation)" (Hardware) and the 1.0+ (1.1, 1.12, 2.0, 3.0, etc.) Software versioning convention often used to designate general software product releases. It is often abbreviated as MK, Mk or M. Because a mark is often made to measure height or progress, by metonymy the word mark is used to note a defined level of development thus designations like "Mark I", "Mark II", "Mark III", "Mark IV", etc. come to be used as proper names. However, since the same name is used for a wide variety of products, it can have varied connotations for different persons.

Usage[edit]

United Kingdom[edit]

In British military practice, Mark designations have been given in Roman numerals, often as sub-designations of "Number" designations. For example, the Number 1 rifle, the Number 2 rifle, etc. were major types of equipment, with "Mark" designating a minor variant or production change, i.e. "Number 1 Mark III" or "Number 4 Mark I."

United States Navy[edit]

The United States Navy uses the terms "MARK" and "MOD" as a method to uniquely designate specific types and configurations of equipment that would otherwise lack military designations. The practice was adopted by the Naval Ordnance group in 1944, and was formalized in MIL-STD-1661[1] in 1978. As the system came from the Ordnance group, it is primarily used to describe naval guns, gun mounts, and other similar weapon systems.
