NATO uses a system of code names , called reporting names , to denote military aircraft and other equipment used by post-Soviet states , former Warsaw Pact countries, China , and other countries. The system assists military communications by providing short, one or two-syllable names, as alternatives to the precise proper names , which may be easily confused under operational conditions or are unknown in the Western world .

22-540: The Vympel K-13 ( NATO reporting name : AA-2 " Atoll " ) is a short-range, infrared homing air-to-air missile developed by the Soviet Union . It is similar in appearance and function to the American AIM-9B Sidewinder from which it was reverse-engineered . Although it since has been replaced by more modern missiles in frontline service, it saw widespread service in many nations. During

44-637: A semi-active radar homing (SARH) version for high-altitude use, the K-13R ( R-3R or Object 320) with 8 km range, similar to the little-used US Navy AIM-9C Sidewinder (carried by the F-8 Crusader ). This took longer to develop, and while its first launches were in 1963, it did not enter service until 1967, alongside the radar required for it, the RP-22S, on the MiG-21S, produced from 1965. This missile

66-466: A different series of numbers with a different suffix (i.e., SA-N- versus SA-) for these systems. The names are kept the same as a convenience. Where there is no corresponding system, a new name is devised. 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

88-518: A group of MiG-17s cruised past a flight of Sabres, only for them to be attacked by missiles. This was the first instance of guided missiles being used in air-to-air combat. On 28 September 1958, a similar engagement resulted in one of the missiles becoming lodged in a MiG-17 without exploding, allowing it to be removed after landing. The Soviets later became aware that the Chinese had at least one Sidewinder, and after some wrangling, were able to persuade

110-578: A more ambitious upgrade in the late 1960s, emerging as the K-13M ( R-13M , Object 380) for the IRH and K-13R ( R-3R ) for the SARH variant, were developed in the late 1960s. These were dubbed Advanced Atoll ( AA-2C and AA-2D , respectively) in the west. The R-13M was roughly equivalent to the improved USN AIM-9G Sidewinder, with a new proximity fuse , more propellant for longer range, better maneuverability, and

132-645: A more sensitive nitrogen -cooled seeker head. None were all-aspect missiles. The same electronics upgrades were also applied to the Kaliningrad K-5 (AA-1) to arm fighters that did not carry the K-13. The K-13 in different versions was widely exported to the Warsaw Pact and other air forces, and remains in service with a few smaller nations. A license-built version called A-91 was built in Romania, and

154-522: A native 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. To reduce the risk of confusion, unusual or made-up names are allocated, the idea being that the names chosen are unlikely to occur in normal conversation and are easier to memorise. For fixed-wing aircraft, the number of syllables indicates

176-456: Is not made for helicopters. Before the 1980s, reporting names for submarines were taken from the NATO spelling alphabet . Modifications of existing designs were given descriptive terms, such as " Whiskey Long Bin ". From the 1980s, new designs were given names derived from Russian words, such as " Akula ", or "shark". These names did not correspond to the Soviet names. Coincidentally, "Akula", which

198-863: The Antonov An-124 or "Candid" for the Ilyushin Il-76 . The initial letter of the name indicates the use of that equipment. The alphanumeric designations (eg AA-2) are assigned by the Department of Defense . The first letter indicates the type of aircraft, e.g., "Bear" for a bomber aircraft refers to the Tupolev Tu-95 , or "Fulcrum" for the Mikoyan-Gurevich MiG-29 fighter aircraft. For fixed-wing aircraft, one-syllable names are used for propeller aircraft and two-syllable names for aircraft with jet engines. This distinction

220-638: The People's Republic of China copied the K-13 as the PL-2 . Updated Chinese versions were the PL-3 and PL-5 . Soviet Union provided China K-13 missile technology as a part of MiG-21 fighter jet deal in 1962. In 1967, China successfully completed locally produced K-13 (PL-2) missile tests, and started to deploy this missile to combat units. It was first used to intercept USAF UAVs flown from Vietnam and other south east Asian countries to mainland China. The K-13 missile

242-663: The Second Taiwan Strait Crisis in 1958, Taiwan's F-86 Sabres faced the much higher performance mainland Chinese PLAAF MiG-17s . The MiG-17s had speed, maneuverability, and altitude advantages over the Sabres, allowing them to engage only when they desired, normally at advantageous times. In response, the US Navy rushed to modify 100 ROCAF Sabres to carry the newly introduced AIM-9 Sidewinder missile. These were introduced into combat on 24 September 1958, when

264-813: The Yom Kippur War by the Arab Air Forces in 1973, and during the Iran–Iraq War by the Iraqi Air Force between 1980 and 1988. On 19 August 1981, during the 1981 Gulf of Sidra incident , a Libyan Air Force Su-22 fired a K-13 missile head on at approaching US Navy F-14 As; the missile was evaded. NATO reporting name The assignment of reporting names is managed by the Five Eyes Air Force Interoperability Council (AFIC), previously known as

286-649: The Air Standardization Coordinating Committee (ASCC), which is separate from NATO . Based in Washington DC, AFIC comprises representatives from the militaries of three NATO members (Canada, the United Kingdom and United States) and two non-NATO countries (Australia and New Zealand). When the system was introduced in the 1950s, reporting names also implicitly designated potentially hostile aircraft. However, since

308-486: The Chinese example. The Sidewinder was quickly reverse engineered as the K-13 (also called R-3 or Object 300) and entered limited service only two years later in 1960. This was followed by the improved K-13A ( R-3S , Object 310), which entered service in 1962. The R-3S was the first version to enter widespread production, in spite of a very long seeker settling time on the order of 22 seconds, as opposed to 11 seconds for

330-521: The Chinese to send them one of the captured missiles. Gennadiy Sokolovskiy, later chief engineer at the Vympel team, said that "the Sidewinder missile was to us a university offering a course in missile construction technology which has upgraded our engineering education and updated our approach to production of future missiles." A subsequent claim was made by Ron Westrum in his book Sidewinder that

352-745: The Israeli Air Force. In the late 1960s and early 1970s, the Israelis shot down dozens of MiGs – but there had been no success in using this missile, as Israeli pilots preferred to use cannons or indigenous missiles such as Shafrir 1 and Shafrir 2 . K-3 or K-13 missiles were also used during the Indo-Pakistani War of 1971 by the Indian Air Force; they were integrated on MiG-21FLs and used to shoot down at least two to four Pakistani F-104 Starfighters . They were used during

374-456: The Soviets obtained the plans for the Sidewinder from Swedish Colonel and convicted spy Stig Wennerström , and rushed their version into service by 1961 copying it so closely that even the part numbers were duplicated. Although Wennerström did leak information of the Sidewinder after negotiating its purchase for Sweden, none of the known Soviet sources mention this, while all explicitly mention

396-517: The end of the Cold War, some NATO air forces have operated various aircraft types with reporting names (e.g. the "Fulcrum" Mikoyan MiG-29 ). The United States Department of Defense (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

418-591: The original version. The R-3S was seen by the West in 1961 and given the NATO reporting name AA-2A 'Atoll' . Minimum engagement range for the R-3S is about one kilometre. All K-13 variants are physically similar to Sidewinder, sharing the 5 inch (127 mm) diameter. Subsequent examination of AA-2 missiles captured by NATO forces showed that parts from an AIM-9 could be interchanged with parts from an AA-2 and either combination would still work. In 1962, work started on

440-588: The type of the aircraft's engine. Single-syllable code names denote reciprocating engine or turboprop , while two-syllable code names denote jet engine . Bombers have names starting with the letter "B", and names like "Badger" ( Tupolev Tu-16 ), "Blackjack" ( Tupolev Tu-160 ) and "Bear" ( Tupolev Tu-95 ) have been used. "Frogfoot", the reporting name for the Sukhoi Su-25 , references the aircraft's close air support role. Transports have names starting with "C" (for "cargo"), resulting in names like "Condor" for

462-481: Was available on all subsequent MiG-21 variants. This version was designated AA-2B by NATO. Three training versions were also developed. The R-3U ("uchebnaya", training) was an empty missile body with a homing set, allowing pilots to get used to the aiming of the system. The R-3P ("prakticheskaya", practice) was a complete missile without an explosive warhead. The RM-3V ("raketa-mishen", target-missile) served as an aerial target. The Vympel team started working on

484-734: Was used by North Vietnamese MiG-21 pilots. Due to the NVAF's very limited number of MiG-21s, their common tactic was to approach an American formation at maximum reasonable speed, fire their missiles in volleys, and exit the area at maximum speed to avoid engagement. Some of these missiles were seized by Israel during the Six-Day War in the Sinai Peninsula. They were used during the War of Attrition , by Squadron 101 (Mirage IIICJ) and probably also by 117 and 119 squadrons, all Mirage squadrons of
