PLAAF KJ-200 — Airborne Early Warning (AEW&C)
Open in interactive gallery →See aircraft like this on the live radar →

The KJ-200 Moth (Chinese: Kongjing-200, "Air Police 200"; PLAAF designation) is a Chinese airborne early warning + control (AEW&C) aircraft — China's medium-class AEW&C platform based on the Shaanxi Y-8 transport airframe. CETC (China Electronics Technology Group) + AVIC Shaanxi jointly developed the KJ-200 in 2001-2005; first flight occurred in 2001. About 11 KJ-200s have been built between 2006 and 2024. The aircraft serves PLAAF + PLA Naval Air Force AEW&C roles.

The KJ-200 uses the Shaanxi Y-8F-600 four-turboprop airframe. Maximum speed 660 km/h, endurance 11 hours, service ceiling 10,400 m. Mission equipment: AESA radar in a distinctive over-fuselage "balance-beam" antenna housing (similar to the Swedish Saab Erieye configuration) + 10-mission-operator workstation cabin + extensive ELINT + communications systems. The KJ-200 detects + tracks aircraft-sized targets at 350-500 km range — providing medium-class AEW&C coverage for PLAAF long-range air-defence operations.

KJ-200 service is concentrated in PLAAF + PLA Naval Air Force AEW&C duties. The aircraft operates from Eastern + Northern China bases providing air-defence early warning + fighter direction in the East China Sea + Yellow Sea + Taiwan Strait operating environments. A 2006 KJ-200 crash near Anhui Province killed 40 PLAAF personnel including ~half the Chinese AEW&C expert community — notably delayed the programme. The KJ-200 is supplemented by the larger KJ-500 (more-capable AESA radar) for high-priority missions.

For Kids — a shorter, friendlier version

The KJ-200 is a Chinese spy plane that watches the sky. Its full name is "Air Police 200." It is built to spot other aircraft from very far away. China started working on it in 2001 and finished the first one by 2006.

The KJ-200 is based on a large cargo plane called the Y-8. It has four turboprop engines to keep it flying. It can stay in the air for up to 11 hours at a time. That is longer than most school days!

On top of the plane sits a special radar shaped like a long beam. This radar can detect aircraft that are up to 500 km away. That is farther than many road trips between cities. Ten crew members sit inside and watch the radar screens.

The KJ-200 flies for China's air force and navy air force. About 11 of these planes have been built between 2006 and 2024. They fly from bases in eastern and northern China. Their job is to find other aircraft early and help guide Chinese fighter planes.

Fun Facts

  • The KJ-200 can spot aircraft that are farther away than the distance from New York City to Boston!
  • It can stay in the air for 11 hours — longer than a flight from the US to Europe.
  • The radar on top looks like a long balance beam, sitting flat above the body of the plane.
  • About 11 of these planes have been built over nearly 20 years.
  • The plane can fly as fast as 660 km/h, faster than most propeller-driven aircraft.
  • Ten mission crew members work at computer stations inside the plane.
  • The KJ-200 can fly as high as 10,400 meters — higher than the tallest mountain on Earth.
  • China's air force and navy air force both use the KJ-200 to guard the skies.

Kids’ Questions

What does the KJ-200 do?

The KJ-200 looks for other aircraft in the sky using a powerful radar. It can detect planes from up to 500 km away. Then it helps guide friendly fighter planes to respond. Think of it as a flying air-traffic spotter for the military.

What is the strange beam on top of the plane?

That long beam is a special radar antenna called a balance-beam radar. It scans the sky to find aircraft far away. It sits on top of the plane so it has a clear view in all directions. A similar design is used on some other countries' scouting planes too.

How many KJ-200 planes exist?

About 11 KJ-200 planes have been built between 2006 and 2024. That is a fairly small number for a military aircraft. Each one is very expensive and complex to make.

Variants

KJ-200 (basic)
Standard AEW&C variant. About 11 built.

Notable Operators

PLAAF + PLA Naval Air Force
Sole operator. ~11 KJ-200s in service. Eastern + Northern China bases.

Frequently Asked Questions

Why does the KJ-200 have a balance-beam antenna?

The over-fuselage "balance-beam" antenna housing accommodates the AESA radar's phased-array antennas in a fixed configuration — providing 360° coverage without the rotating-rotodome configuration of the American E-3 Sentry. Saab Erieye system was the original innovator of the balance-beam configuration; KJ-200 + several other modern AEW&C platforms (Embraer R-99, KAI E-737 "Peace Eye") adopted similar layouts. The configuration is simpler + lighter + more-reliable than rotodomes.

What was the 2006 KJ-200 crash?

On 3 June 2006, a KJ-200 prototype crashed near Anhui Province during a training flight. All 40 PLAAF personnel aboard were killed — approximately half of China's AEW&C expert community at that time. The crash notably delayed the KJ-200 programme + caused PLAAF to consolidate AEW&C expertise + accelerate the KJ-500 successor programme. The cause was attributed to icing-induced loss of control.
