or name used, sometimes clandestinely, to refer to another name, word, project, or person. Code names are often used for military purposes, or in espionage. They may also be used in industrial counter-espionage to protect secret projects and the like from business rivals, or to give names to projects whose marketing name has not yet been determined. Another reason for the use of names and phrases in the military is that they transmit with a lower level of cumulative errors over a walkie-talkie or radio link than actual names.

Military operations since Churchill

Throughout the Second World War, the British allocation practice favored one-word code names ( Jubilee, Frankton). That of the Americans favored longer compound words, although the name

was particular about the quality of code names. He insisted that code words, especially for dangerous operations, would be not overly grand nor petty nor common. One emotional goal he mentions is to never have to report to anyone that their son "was killed in an operation called 'Bunnyhug' or 'Ballyhoo'." Presently, British forces tend to use one-word names, presumably in keeping with their post-World War II policy of reserving single words for operations and two-word names for exercises. British operation code names are usually randomly generated by a computer and rarely reveal its components or any political implications unlike the American names (e.g., the

for the stealth fighter development, are developmental programs, not meant to produce a production aircraft. Programs that start with Senior, such as Senior Trend for the F-117, are for aircraft in testing meant to enter production. In the United States code names are commonly set entirely in upper case. This is not done in other countries, though for the UK in British documents the code name is in upper case while operation is shortened to OP e.g., "Op. TELIC". This presents an opportunity for a bit of public-relations (

of the project against rival concerns. Some corporations routinely change project names in order to further confuse competitors. * When the goal of the project is to develop one or more commercial ''products'', use of a code name allows the eventual choice of product nomenclature (the name the product(s) are marketed and sold under) to be decoupled from the development effort. This is especially important when one project generates multiple products, or multiple projects are needed to produce a single product. This allows for ''subprojects'' to be given a separate identity from the main project. * To decouple an early phase of a development effort (which may have failed) from a subsequent phase (which may be given a "fresh start") as a political tool. * To prevent casual observers from concluding that a pre-release version is a new release of the product, thus helping reduce confusion. Different organizations have different policies regarding the use and publication of project code names. Some companies take great pains to ''never'' discuss or disclose project code names outside of the company (other than with outside entities who have a need to know, and typically are bound with a
