China's Pla Enhances The Capability Of Its Helicopter Fleet

Its armament features a cannon, likely of 23mm caliber, as well as a pair of stub wings that each possess three weapon stations for rockets and missiles

In a significant stride towards self-reliance, China's aerospace sector has transitioned from dependence on Russian and reverse-engineered European helicopters to designing and manufacturing its own range of aircraft. The latest addition to this endeavor is a cutting-edge heavy-attack helicopter, reminiscent of the American AH-64 Apache.

Photographs captured by Chinese citizens, albeit in low resolution, surfaced on the internet in late March, showcasing the new attack helicopter undergoing flight testing.

Speculation suggests that this clandestine aircraft undertook its inaugural flight as early as January. While its official designation remains uncertain, it is commonly referred to as the Z-21.

What sets the Z-21 apart is its lineage traced back to the Z-20 utility helicopter. Andreas Rupprecht, a noted German authority on Chinese aviation, remarked to the media, "Now with the first images at hand, it's almost surprising that we didn't put together those piec es we've known for years." He elaborated on the evolution of the Z-20 into a mature system, highlighting the appearance of prototypes featuring enhanced sensors and armaments. Thus, the Z-21, leveraging the proven powertrain, transmission, engines, and tail arrangement of the Z-20, coupled with a refined fuselage, represents a logical progression in China's helicopter development journey.

By making use of Z-20 components, China can accelerate the new platform's development and also reduce risk. Reusing the Z-20's tail boom, the new Z-21 has a slim, tandemseat fuselage with wide cheek fairings, just like the Apache does. Like modernized variants of the Z-10, the Z-21's engine exhausts face upwards to reduce the aircraft's infrared signature and thus improve its chances against surface-to-air missiles.
