CIA cryptonyms are code names or code words used by the U.S. Central Intelligence Agency to reference projects, operations, persons, agencies, etc. The cryptonyms as described in this article were in use at least from the 1950s to the 1980s. It is likely that they have since been replaced by another system.

The term "code word" was used by the CIA during the 1960s as a partial designation for a Top Secret report on a highly classified and sensitive intelligence topic, and for compartmenting information. In the context of discussing code words used in the President's Daily Brief (PDB) during the Johnson and Nixon administrations, former CIA Director Richard Helms wrote: "At the time, the highest security classification was known as Top Secret/Code Word. In practice, the slug--as we called it--'Top Secret/Code Word' was followed by a noun, so scrupulously chosen that even the most intuitive intruder could not associate a glimpse of the code word with the subject matter it protected. In my day there were a dozen or more of these tightly compartmented classifications of information. Aside from the President and a few others--usually the secretary of state, secretary of defense, and national security advisor--no other government official was automatically cleared for 'all source' reports. The lesser recipients of specific code word data had to have a clearly established 'need to know' the substance of the compartmentalized report. Compartmentation, as we called it, is one of the most effective means of protecting sensitive data. As surely as Heaven gave us little green apples, it would be my luck to pick a five-letter noun that is in current use." Top Secret/Code Word documents contained "highly classified and sensitive intelligence."[1]

Format of cryptonymsEdit

Each CIA cryptonym contains a two character prefix called a digraph, which designates a geographical or functional area. Certain digraphs were changed over time; for example, the digraph for the Soviet Union changed at least twice.

The rest is either an arbitrary dictionary word, or occasionally the digraph and the cryptonym combine to form a dictionary word (e.g. AEROPLANE) or can be read out as a simple phrase (e.g. WIBOTHER, read as "Why bother!"). Cryptonyms are sometimes written with a slash after the digraph, e.g. ZR/RIFLE, and sometimes in one sequence, e.g. ZRRIFLE. The latter format is the more common style in CIA documents.

Examples from publications by former CIA personnel show that the terms "code name" and "cryptonym" can refer to the names of operations as well as to individual persons. TRIGON, for example, was the code name for Aleksandr Ogorodnik, a member of the Ministry of Foreign Affairs in what was then the Soviet Union, whom the CIA developed as a spy,[2] and Col. Oleg Penkovsky, who supplied data on the nuclear readiness of the Soviet Union during the Cuban Missile Crisis of 1962, was assigned code name HERO.[3] According to former CIA Director Richard M. Helms: "The code names for most Agency operations are picked in sequence from a sterile list, with care taken not to use any word that might give a clue to the activity it covers. On some large projects, code names are occasionally specially chosen--GOLD, SILVER, PBSUCCESS, CORONA. When Bob Kennedy requested a code name for the government-wide plan that Richard Goodwin was drafting, an exception was made. Goodwin was on the White House staff, and the plan concerned Cuba. Occasionally the special code names come close to the nerve, as did MONGOOSE.[4] A secret joint program between the CIA's Mexico City station and the Mexican secret police to wiretap the Soviet and Cuban embassies was code-named ENVOY.[5]

Some cryptonyms relate to more than one subject, e.g. a group of people. In this case the basic cryptonym, e.g. LICOZY, will designate the whole group, while each group member is designated by a sequence number, e.g. LICOZY/3, which can also be written LICOZY-3.

If several references are made to the same cryptonym in a document, the cryptonym will often be abbreviated the second and subsequent times, to save encryption effort. Thus LICOZY-3, for example, might be abbreviated just L-3.

Operations and Projects Edit

More than 20 digraphs pertaining to CIA efforts to overthrow and/or assassinate Fidel Castro, and other CIA activities, have been documented by Lamar Waldron and Thom Hartmann in Legacy of Secrecy: The Long Shadow of the JFK Assassination (Berkeley, CA: Counterpoint, 2009) and Ultimate Sacrifice: John and Robert Kennedy, the Plan for a Coup in Cuba, and the Murder of JFK (New York: Carroll & Graf Publishers, 2005). Page references below are to Legacy of Secrecy (LS) and Ultimate Sacrifice (US). Waldron and Hartmann note: "Even seasoned historians have had trouble distinguishing AMWORLD from AMTRUNK from AMLASH, and figuring out where programs like the CIA-Mafia plots fit in." (LS, page 224).

  • AMBIDDY-1: Manuel Artime (US, page 878).
  • AMCLATTER-1: Bernard Leon Barker (1917-2009), one of the Watergate burglars; (LS, page 262).
  • AMLASH: Plan to assassinate Fidel Castro associated mainly with Rolando Cubela, who is often identified as AMLASH, but was also referred to as AMLASH-1. AMLASH has been referred to as a "basically one-person Cubela operation." (US, page 215).
  • AMOT: Cuban exile informants of David Morales (LS, page 38).
  • AMTHUG: Fidel Castro (LS, page 35).

(US, page 215). AMTRUNK has also been described as a "CIA-DIA Task Force on Cuba" (LS, page 224), and the latter has also been characterized as "a plodding bureaucratic effort" that "had worlked for months to identify Cuban leaders who might be able to stage a coup." (US, page 216).
  • AMWHIP-1: Business associate of Santos Trafficante who was in contact with Rolando Cubela (AMLASH) in 1963 (LS, page 19).
  • AMWORLD: A plan initiated June 28, 1963, to overthrow the Castro regime in a coup on December 1, 1963 (C-Day), that would have installed Juan Almeida Bosque (1927–2009), a top ranking Cuban military officer, as the new head of state (LS, page 13; US, page 794).
  • MURKIN: Martin Luther King, Jr. assassination files (LS, page 516). Digraph possibly based on "Murder King" or "King Murder".
  • QJWIN: European assassin (LS, page 35).
  • QKENCHANT: Classified CIA program associated with E. Howard Hunt (1918-2007), who with G. Gordon Liddy and others, was one of the White House's "plumbers" — a secret team of operatives charged with fixing "leaks." (LS, page 709).

Other diagraphs associated with CIA and Cuba, whose meanings are not explained, include AMCLEOPATRA, AMCOBRA, AMCROW, AMCRUZ, AMHALF, AMFOX, AMGLOSSY and AMJUDGE, AMPALM-4 (US, page 794), GPIDEAL (US, page 894), ODYOKE (US, page 794; but identified below as "Federal Government of the United States"), PBPRIME (US, page 794); all others LS, page 204.
