The Xian Y-20 (Chinese: 运-20; pinyin: Yun-20) is a large military transport aircraft. The project was officially launched on 2006. It is being developed by Xi'an Aircraft Industrial Corporation for the Chinese PLAAF.
The Y-20 prototype is powered by four Russian D30 series turbofan engines and the production aircraft will sport the WS-20 engines. Cargo is loaded through a large aft ramp that accommodates rolling stock. The Y-20 is similar to C-17 transport aircraft in general layout. The Y-20 incorporates a high-set wing, T-tail, rear cargo-loading assembly and heavy-duty retractable landing gear.
