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.

. This procedure was coordinated with the United States when America entered the war. Random lists of names were issued to users in alphabetical blocks of ten words and were selected as required. Words became available for re-use after six months and unused allocations could be reassigned at discretion and according to need. Judicious selection from the available allocation could result in clever meanings and result in an

Those for the major conference meetings had a partial naming sequence referring to devices or instruments which had an ordinal number as part of their meaning, e.g., the third meeting was "TRIDENT".

Code names of other powers

Britain and the United States developed the security policy of assigning code names intended to give no such clues to the uninitiated. For example, the British counter measures against the V-2 was called '' Operation Crossbow''. The atomic bomb project centered in

The code name for the American A-12 / SR-71 spy plane project, producing the fastest, highest-flying aircraft in the world, was ''Oxcart''.

''. The Soviet Union's project to base missiles in Cuba was named '' Operation Anadyr'' after their closest bomber base to the US (just across the Bering Strait from Nome, Alaska). The names of colors are generally avoided in American practice to avoid confusion with meteorological reporting practices. Britain, in contrast, made deliberately non-meaningful use of them, through the system of rainbow codes.


Aircraft recognition reporting names

Although German and Italian aircraft were not given code names by their Allied opponents, in 1942, Captain Frank T. McCoy, an intelligence officer of the
USAAF The United States Army Air Forces (USAAF or AAF) was the major land-based aerial warfare service component of the United States Army and ''de facto'' aerial warfare service branch of the United States during and immediately after World War II ...
, invented a system for the identification of Japanese military aircraft. Initially using short, " hillbilly" boys' names such as " Pete", " Jake", and " Rufe", the system was later extended to include girls' names and names of trees and birds, and became widely used by the Allies throughout the Pacific theater of war. This type of naming scheme differs from the other use of code names in that it does not have to be kept secret, but is a means of identification where the official nomenclature is unknown or uncertain. The policy of recognition reporting names was continued into the Cold War for Soviet, other

as the NATO reporting name for aircraft, rockets and missiles. These names were considered by the Soviets as being like a nickname given to one's unit by the opponents in a battle. The Soviets did not like the Sukhoi Su-25 getting the code name " Frogfoot". However, some names were appropriate, such as "Condor" for the Antonov An-124, or, most famously, "Fulcrum" for the Mikoyan MiG-29, which had a "pivotal" role in Soviet air-strategy. Code names were adopted by the following process. Aerial or space reconnaissance would note a new aircraft at a

airbase. The intelligence units would then assign it a code name consisting of the official abbreviation of the base, then a letter, for example, "Ram-A", signifying an aircraft sighted at Ramenskoye Airport. Missiles were given designations like "TT-5", for the fifth rocket seen at Tyura-Tam. When more information resulted in knowing a bit about what a missile was used for, it would be given a designation like "SS-6", for the sixth surface-to-surface missile design reported. Finally, when either an aircraft or a missile was able to be photographed with a hand-held camera, instead of a reconnaissance aircraft, it was given a name like "
Flanker Flanker may refer to: * Flanker (perfume), a newly created perfume sharing attributes of an existing one * Flanker (rugby union), a position in rugby union (not found in rugby league) * ''Su-27 Flanker'' (video game), a 1996 computer game modelin ...
" or " Scud" always an English word, as international pilots worldwide are required to learn English. The Soviet manufacturer or designation – which may be mistakenly inferred by NATO – has nothing to do with it. Jet-powered aircraft received two-syllable names like Foxbat, while propeller aircraft were designated with short names like

. Fighter names began with an "F", bombers with a "B", cargo aircraft with a "C". Training aircraft and reconnaissance aircraft were grouped under the word "miscellaneous", and received "M". The same convention applies to missiles, with air-launched ground attack missiles beginning with the letter "K" and surface-to-surface missiles (ranging from intercontinental ballistic missiles to antitank rockets) with the letter "S", air-to-air missiles "A", and surface-to-air missiles "G".


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 Overlord was personally chosen by Winston Churchill himself. Many examples of both types can be cited, as can exceptions. Winston Churchill 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 2003 invasion of Iraq was called "Operation Telic" compared to Americans' "Operation Iraqi Freedom", obviously chosen for propaganda rather than secrecy). Americans prefer two-word names, whereas the Canadians and Australians use either. The French military currently prefer names drawn from nature (such as colors or the names of animals), for instance ''

'' ("brocket deer") or '' Opération Baliste'' ("Triggerfish"). The CIA uses alphabetical prefixes to designate the part of the agency supporting an operation. In many cases with the United States, the first word of the name has to do with the intent of the program. Programs with "have" as the first word, such as Have Blue 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 (
Operation Just Cause Operation or Operations may refer to: Arts, entertainment and media * ''Operation'' (game), a battery-operated board game that challenges dexterity * Operation (music), a term used in musical set theory * ''Operations'' (magazine), Multi-Ma ...
), or for controversy over the naming choice (Operation Infinite Justice, renamed Operation Enduring Freedom). Computers are now used to aid in the selection. And further, there is a distinction between the ''secret'' names during former wars and the ''published'' names of recent ones.

A project code name is a code name (usually a single word, short phrase or acronym) which is given to a
project A project is any undertaking, carried out individually or collaboratively and possibly involving research or design, that is carefully planned to achieve a particular goal. An alternative view sees a project managerially as a sequence of even ...

, government, and other concerns. Project code names are typically used for several reasons: * To uniquely identify the project within the organization. Code names are frequently chosen to be outside the normal business/domain jargon that the organization uses, in order to not conflict with established terminology. * To assist with maintaining secrecy 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
non-disclosure agreement A non-disclosure agreement (NDA) is a legal contract or part of a contract between at least two parties that outlines confidential material, knowledge, or information that the parties wish to share with one another for certain purposes, but wis ...
). Other companies never use them in official or formal communications, but widely disseminate project code names through informal channels (often in an attempt to create a marketing buzz for the project). Still others (such as

) discuss code names publicly, and routinely use project code names on beta releases and such, but remove them from final product(s). In the case of Windows 95, the code name "CHICAGO" was left embedded in the INF File structure and remained required through Windows Me. At the other end of the spectrum, Apple Computer includes the project code names for Mac OS X as part of the official name of the final product, a practice that was started in 2002 with Mac OS X v10.2 "Jaguar".
