KJ-1 AEWC

The KJ-1 (from Chinese: 空警; pinyin: Kōng Jǐng, short for 空中预警 kōngzhōng yùjǐng meaning "airborne early warning") was a Chinese experimental airborne early warning (AEW) aircraft, based on a Tupolev Tu-4 bomber aircraft (itself being an unlicensed, reverse engineered copy of the Boeing B-29 Superfortress). The project was started in 1969 under the code name "Project 926", but only one prototype was built before the project was put on hold indefinitely until it was finally cancelled in 1979.
