Quietly Authoritative — 11 museum-grade prints that set the mood. The Kamov Ka-52 Alligator — NATO reporting name Hokum-B — evolved from the single-seat Ka-50 Black Shark into a two-seat reconnaissance-attack platform with side-by-side crew seating and Kamov's signature coaxial counter-rotating rotor system, eliminating a conventional tail rotor. Fielded from 2011 into Russian army aviation service, it carries 9K121 Vikhr and 9M120 Ataka anti-tank missiles plus a side-mounted 2A42 30 mm cannon for day-night, all-weather close support. 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 Harbin Z-19 — nicknamed Black Whirlwind (霹雳火) — entered PLA Army Aviation service from 2012 as a tandem-seat scout-attack helicopter derived from the Z-9 utility lineage, itself a licence-built Eurocopter Dauphin derivative. The Z-19E export variant conducted its maiden flight in May 2017 at Harbin in Heilongjiang province, showcasing refined avionics, mast-mounted fire-control sensors, fenestron tail-rotor shrouding, and stub-wing stores including HJ-10 anti-tank guided missiles.
