Chinese Aircraft Designations

Since 1964 every PLA aircraft has carried a pinyin role prefix and a number: J (歼, jiān) fighter, H (轰, hōng) bomber, Y (运, yùn) transport, Z (直, zhí) helicopter, with two-letter prefixes for trainers, early-warning aircraft and drones. Each prefix counts its own sequence from 5 — the numbers below it belong to imported Soviet types — and a variant letter follows the number, so J-10C reads "fighter, tenth design, third version". The one structural rule is that the prefix names the role, never the maker: Chengdu and Shenyang fighters share the J series. Before 1964 the same aircraft wore Dongfeng project numbers and a "Type" year, which is why the J-5 was first the Dongfeng-101 and the Type 56.

One lane per prefix family, one dot per type entering service — prototypes and demonstrators sit at first flight. The first decade is licensed Soviet types renamed in 1964; the embargo decades add derivatives and the first indigenous designs; the J-11 opens the fourth generation in 1998 and the J-20 the stealth era with its first flight in 2011. The round numbers — J-20, Y-20, Z-20, J-35, KJ-500 — all belong to the last fifteen years.

The fighter count is the system in miniature. It opens at 5 because the numbers below went to the imported MiGs, and the first three entries are the licensed MiG-17, MiG-19 and the reverse-engineered MiG-21: J-5, J-6, J-7. The J-8 was an enlarged J-7; the J-9 and J-13 were cancelled designs, the first J-11 a 1969 light fighter abandoned for want of an engine, and the J-12 a 3-tonne prototype flown in 1970 and dropped in 1977. The number 11 was then reused for the licensed Su-27, and 10, 15 and 16 ran in order of program. After the J-16 the sequence jumps: 20 for the stealth fighter and 35 for the carrier stealth fighter are round numbers chosen for weight, not the next free slots. The two tailless demonstrators flown in December 2024 are called J-36 and J-50 by analysts only — the first after the 36011 serial painted on the airframe.

Two bomber numbers have carried the whole force since the 1960s: the H-5, an Il-28 copied in Harbin without a license, and the H-6, the Tu-16 built under one at Xi'an. On the H-6 the suffix letters are the history — D for the 1980s naval anti-ship carrier, G and J for the later naval versions, K for the re-engined cruise-missile carrier that first flew on 5 January 2007 and entered service in October 2009, N for the refuelable version the Pentagon's 2024 report lists as fielded with nuclear-capable missiles, M for the WZ-8 mother ship, HY-6 for the tanker. Q (qiáng) covers the Nanchang Q-5, a MiG-19-derived attack jet first flown on 4 July 1965 and sold as the A-5, with the A-5C fitted with Western instruments for export. JH (jiānhōng) marks the fighter-bomber JH-7, marketed as the FBC-1 Flying Leopard, and SH (shuǐhōng, seaplane bomber) the SH-5 amphibian, of which one prototype and six production aircraft were built.

The transport line is Antonov by descent: the Y-7 is the licensed An-24, the Y-8 an An-12 reverse-engineered after Soviet assistance was withdrawn, the Y-9 a stretched Y-8 whose designation was in use by September 2005. The Y-12 is Harbin's own twin turboprop, FAA-certified in 1995, and the Y-20 Kunpeng, first flown on 26 January 2013, the first large jet airlifter. Special-mission aircraft take a prefix of their own on these airframes. KJ (kōngjǐng, air warning) numbers its radar aircraft in hundreds: the Il-76-based KJ-2000, the Y-8-based KJ-200 begun in 2002 after the Israeli Phalcon sale was blocked, the Y-9-based KJ-500. KQ (kōngqián, air-submarine) gives the KQ-200 patrol aircraft, also written Y-8Q or Y-9Q after its airframe. The Y-8 electronic versions are known by GX (gāoxīn, "high new") numbers as well — the KJ-200 is the GX-5, the KQ-200 the GX-6.

Z (zhí, from zhíshēngjī) is the only prefix a helicopter gets: unlike the US system there is no attack or cargo letter in front, so the role sits in the suffix or nowhere. The first numbers are French. The Z-8 is the SA 321 Super Frelon, licensed in 1976, with the first Chinese-built example flown on 11 December 1985; the Z-9 the AS365 Dauphin under a patent bought in October 1980, with the Z-9W armed version from the early 1990s and the Z-9C for the navy; the Z-11 is modelled on the AS350. The gunships follow: the Z-10, preliminary design by Kamov, first flown on 29 April 2003, and the Z-19, a tandem-seat rebuild of the Z-9W. The Z-18 is the Z-8G, a Super Frelon descendant by way of the civil AC313, and the Z-20, first flown on 23 December 2013, is the 10-tonne utility type in the class of the S-70C-2s bought in 1984. ME marks the export Z-10ME.

Trainers carry two prefixes of their own and one modifier. CJ (chūjiào, from chūjí jiàoliànjī, primary trainer) is the piston line: the CJ-5 was a licensed Yak-18, the CJ-6 of 1958 an original design often mistaken for one. JL (jiàoliàn) is the jet line, and every JL type is better known abroad: the JL-8 was proposed with Pakistan in 1986 and renamed Karakorum-8, K-8, at the suggestion of Pakistan's president; the Guizhou JL-9 is the FTC-2000 Mountain Eagle, with an armed FTC-2000G and a land-based carrier-training JL-9G; Hongdu's L-15 Falcon became the JL-10 in PLAAF service while the UAE ordered 12 as L-15s in 2023. The modifier is the second J: a JJ-5, JJ-6 or JJ-7 is the two-seat trainer of the fighter of the same number, exported as the FT-5 and FT-7, and the HJ-5 the trainer version of the H-5 bomber. The JF-17 and the "J" in it are Pakistani: Joint Fighter.

Drones split along the manned rule: WZ (wúzhēn, unmanned reconnaissance) for the sensor carriers, GJ (gōngjī, attack) for the armed ones. The PLA names are often not the names the aircraft are sold under. The Wing Loong I and II of Chengdu, Pterodactyl on the export market, are the GJ-1 and GJ-2 in air force service, the GJ-2 since 2018; the Wing Loong-10 is the WZ-10. The WZ-7 Xianglong is the joined-wing high-altitude type, the WZ-8 the rocket-powered reconnaissance drone revealed at the 1 October 2019 parade and launched from the H-6M, the GJ-11 Lijian, Sharp Sword, the flying-wing combat drone whose program was unveiled in 2009. The Pentagon's 2024 report names all three. The rest are company series: CH for CASC's Cǎihóng, Rainbow, line, BZK for Harbin's BZK-005, TB for Tengden's TB-001, WJ for the CASIC Hiwing family, ASN for the Xi'an ASN institute — labels that say who built the drone, not what the PLA calls it.
