NATO reporting names are code names for military equipment of Russia, China, and, historically, the former Eastern Bloc (Soviet Union and other nations of the Warsaw Pact). They provide unambiguous and easily understood English words in a uniform manner in place of the original designations, which either may have been unknown to the Western world at the time or easily confused codes. For example, the Russian bomber jet Tupolev Tu-160 is simply called Blackjack.
NATO maintains lists of the names. The assignment of the names for the Russian and Chinese aircraft was once managed by the five-nation Air Standardization Coordinating Committee (ASCC) (now called the Air and Space Interoperability Council, or ASIC, which includes representatives of Australia, Canada, New Zealand, the United Kingdom, and the United States), but that is no longer the case.
The United States Department of Defense (US DoD) expands on the NATO reporting names in some cases. NATO refers to surface-to-air missile systems mounted on ships or submarines with the same names as the corresponding land-based systems, but the US DoD assigns a different series of numbers with a different suffix (i.e., SA-N- vs. SA-) for these systems. The names are kept the same as a convenience. Where there is no corresponding system, a new name is devised. Some US DoD nomenclature is included in the following pages and is noted as such.
The Soviet Union did not always assign official "popular names" to its aircraft, but unofficial nicknames were common as in any air force. Generally, Soviet pilots did not use the NATO names, preferring a different, Russian, nickname. An exception was that Soviet airmen appreciated the MiG-29's codename "Fulcrum", as an indication of its pivotal role in Soviet air defence.
