J-10 — Fighter / Attack
Open in interactive gallery →See aircraft like this on the live radar →

China's first domestically designed and produced canard-delta multirole fighter, the Chengdu J-10 (NATO reporting name Firebird) marked a generational leap in indigenous capability for the People's Liberation Army Air Force. Work began in the mid-1980s as Project 10, accelerating after China gained partial access to Israeli Lavi fighter technology following the United States' cancellation of that programme in 1987. The transfer included wind-tunnel data, avionics architecture knowledge, and aerodynamic insights that Chinese engineers folded into the J-10's final configuration. First flight came on 23 March 1998, PLAAF service entry followed in 2004, and the aircraft was publicly disclosed in 2006 after years of speculation in Western intelligence circles.

Visually, the J-10's defining feature is its close-coupled canard mounted ahead of a large delta wing — an arrangement that delivers strong lift and pitch authority at high angles of attack while supporting sustained supersonic flight. Early J-10A airframes used the Russian Saturn AL-31FN turbofan (around 27,560 lbf with afterburner), a deliberate choice to field the fighter quickly while domestic engine work matured. J-10B and J-10C variants brought stronger Chinese avionics including the KLJ-10A active electronically-scanned array radar, and the WS-10B Taihang engine now replaces the AL-31FN across a growing share of the fleet. Entering service around 2017, the J-10C represents the mature production standard: AESA radar, domestic IRST sensor, PLAAF-standard datalink, and the ability to carry the PL-15 active-radar beyond-visual-range missile alongside the helmet-cued PL-10 short-range missile.

By weight class the J-10 sits alongside the F-16 Fighting Falcon and Dassault Mirage 2000: a single-engine lightweight multirole fighter optimised for air superiority and precision strike within a radius of some 1,240 km on internal fuel. The PLAAF flies it alongside the heavier Su-27/Su-30 family and the domestically built J-11 (a licensed-evolving Su-27 derivative) in a high-low mix. China has also offered the J-10C for export as the FC-20; Pakistan, China's closest defence partner, ordered 36 FC-20s to supplement its F-16 fleet, with deliveries starting in 2022 — the first export success of a Chinese supersonic fighter to a foreign military.

Set against Western and Russian 4.5-generation fighters, the J-10C is competitive, though independent assessments place Chinese fighter avionics, electronic warfare, and weapons integration several years behind U.S. standards in some domains. PLAAF doctrine positions the J-10C as the affordable high-volume complement to the expensive J-20 stealth fighter — mirroring the role the F-16 plays alongside the F-22 in the USAF. A further upgraded J-10D variant, with additional RCS reduction features, reportedly flew in 2020 and may enter service in the late 2020s. With over 500 J-10 airframes now in service, the type is the numerical backbone of China's tactical fighter force and the most capable home-grown fighter in the PLAAF inventory below the J-20.

For Kids — a shorter, friendlier version

The Chengdu J-10 is China's main single-engine fighter. It's China's answer to the American F-16. The J-10 first flew in 1998 and entered Chinese service in 2003. About 700 J-10s have been built since then.

The J-10 is about 51 feet long — longer than a school bus. One big WS-10 turbofan engine (Chinese-built). Top speed Mach 2.2 — about 1,460 mph. The J-10 has unusual canard wings — small forward wings near the cockpit.

The J-10 looks like the Israeli Lavi fighter (cancelled 1987). Many believe Israeli engineers helped China with the design. Both countries deny it. But the J-10's similar shape suggests Israeli influence.

The J-10 serves the Chinese Air Force, Chinese Naval Aviation, and Pakistan (which bought 25 J-10C versions). The newest J-10C has modern AESA radar and PL-15 missiles. It is comparable to Western 4.5-generation fighters like the F-16V.

Kids’ Questions

Did Israel really help China build the J-10?

Both countries deny it, but many aviation experts think Israel helped China with the J-10 design. The clues: the J-10 looks very similar to the Israeli Lavi (cancelled 1987). Israel's Lavi had canard wings, the same body shape, and similar systems. After the Lavi was cancelled, Israeli engineers reportedly consulted for China's Chengdu Aircraft Corporation in 1992-1996. The J-10 first flew in 1998 — just a few years later. If Israel did help, both countries kept it secret because Israel was supposed to be a U.S. ally and the U.S. didn't want China getting advanced fighter technology. The truth may not be fully known for decades.

Why do air forces want stealth + canard wings together?

This is a debate. Stealth fighters (F-22, F-35, B-2) use smooth, simple shapes to hide from radar. Canard wings (small forward wings) add extra surfaces that may reflect radar — possibly hurting stealth. But canards make fighters more agile in dogfights. The Chinese J-10 has canards but isn't truly stealthy. The newer J-20 (China's stealth fighter) does have canards — controversially. Western stealth fighters avoid canards entirely. Whether canards + stealth can work together is still debated by aviation engineers. China is betting yes; the U.S. is betting no.

Variants

J-10A
Initial single-seat production variant. AL-31FN engine, KLJ-10 mechanically scanned radar, mixed analogue/digital cockpit. Around 300 built.
J-10AS
Two-seat combat-capable trainer derivative of the J-10A, retaining full weapons capability.

Frequently Asked Questions

Is the J-10 based on the Israeli Lavi?

The J-10 was influenced by the Lavi programme but is not a copy. When the U.S. forced Israel to cancel the Lavi in 1987, China reportedly obtained wind-tunnel data, design documentation, and engineering consultations from Israeli Aircraft Industries, which informed the J-10's canard-delta planform and broader aerodynamic configuration. Chinese engineers reworked the aircraft heavily over the following decade, and the final J-10 airframe differs from the Lavi in dimensions, engine installation, inlet design, and systems architecture.

What engine does the J-10 use?

Early J-10A aircraft were powered by the Russian Saturn AL-31FN turbofan (27,560 lbf thrust). J-10B and J-10C airframes can run either the AL-31FN or the Chinese WS-10B Taihang, which produces similar thrust and is increasingly preferred as China reduces its dependency on Russian engines. Full transition to the WS-10 remains an ongoing priority, and some J-10C regiments are reportedly all-WS-10.

How does the J-10C compare to the F-16V (Viper)?

The J-10C and F-16V are broadly comparable lightweight multirole fighters. Both carry AESA radars, advanced short-range missiles with helmet cueing, and medium-range active radar missiles. The J-10C's PL-15 has a claimed longer range than the AIM-120D, while the F-16V draws on decades of U.S. software integration, broader weapons compatibility, and combat-proven tactics. The J-10C operates more tightly within the PLAAF's own sensor network, making direct comparison difficult without access to classified performance data.

Has the J-10 ever been used in combat?

The J-10 has not seen combat as of 2026 — China has not engaged in aerial combat since the 1950s Taiwan Strait crises. The Pakistan Air Force, the only export operator, has not disclosed use of its FC-20s in the ongoing border tensions with India; Pakistan's combat during the February 2019 skirmish over Kashmir involved F-16s and JF-17s, not J-10s, which had not yet been delivered.

What is the export designation FC-20?

FC-20 is the export marketing designation for the J-10CE (E for export), broadly equivalent to the J-10C with modifications for the Pakistani customer covering weapon interfaces and some different avionics. The FC-20 label distinguishes it from PLAAF-specific variants. China Aircraft Industry Corporation (CAIC) markets it internationally as a lightweight competitor to the F-16V and Gripen.

How many J-10s have been built?

Estimates from Chinese PLAAF order-of-battle assessments suggest over 500 J-10A/B/C airframes had been delivered as of 2025, with J-10C production continuing. The type is manufactured at Chengdu Aircraft Corporation's facility in Chengdu, Sichuan Province — the same plant that builds the J-20 fifth-generation fighter.
