Dark Red — 4 museum-grade prints in this palette. The Chengdu J-10 Vigorous Dragon — Menglong in Chinese, NATO reporting name Firebird — entered PLAAF service in the mid-2000s as China's first indigenously developed fourth-generation multirole fighter, breaking decades of reliance on licensed Soviet designs such as the J-7. Designed around a delta-canard configuration with a single Saturn AL-31FN engine, the J-10A combined agility with PL-8 and PL-12 air-to-air missile integration and marked a pivot toward domestic avionics and production at Chengdu Aircraft Corporation. The Changhe WZ-10, widely marketed internationally as the CAIC Z-10 Fierce Thunderbolt, emerged from a programme accelerated after Gulf War attack-helicopter lessons impressed PLA planners — Harbin Aircraft Industry Group delivered China's first dedicated attack helicopter with tandem seating and stub-wing precision-strike stores rather than repurposed utility airframes. PLA Army Aviation brigades reorganised through the 2017 structural reforms now field mixed attack and transport battalions; the WZ-10 and lighter Harbin Z-19 scout-attack types form the rotary-wing strike layer supporting ground-force manoeuvre. The Shenyang J-15 — Feisha, or Flying Shark — emerged from Shenyang Aircraft Corporation's carrier-fighter program codenamed Flying Shark in 2006, drawing on Su-33 structural lineage and J-11B avionics while adding a reinforced undercarriage, folding wings, and tailhook for naval operations. NATO reporting names include Flanker-X2 and Flanker-K.
