The Kagedan KaG-62 "Chollima" (Saegyan: 천리마, English: Pegasus), or Zahorski Zh-17 "Kajman" (Gorbatovic: Кайман, English: Caiman) is a medium helicopter gunship, attack helicopter and low-capacity troop transport produced by Kagedan Aerospace and Aviation Industry Corporation of Gorbatov (AVIC). It was designed as a replacement for older-model Si-24 "Hind" gunships that filled the same role. It is a product of an intensive, near three-decade long cooperation between Zahorski Design Bureau and Kagedan Aerospace to design a helicopter able to improve upon the performance of the Si-24 in almost all aspects.

The KaG-62 suffered a number of design problems in its early development, which saw it delayed numerous times and nearly cancelled twice. It entered service with the 104th Air Assault Regiment of the Saegyan Revolutionary Army in late 2017, and with the Proletarian Liberation Army a month later. It is intended to supplement "Super Hind" designs and replace older Si-24 models.

Production and improvements[edit]

Design[edit]

The KaG-62's airframe is based very heavily on the Silayev Si-28 attack helicopter, from which it obtains its weapons systems, cockpit layout, and the majority of its fuselage design. It is powered by a pair of Gorbatovic-designed power plants based on the Stasnovan VK-2500, which are some of the most powerful helicopter engines in the world in terms of power to weight ratio, which allow it to perform vertical takeoffs and maneuver in air with full combat and troop loads.

Operational history[edit]

  • H-62/V-90 – Initial prototype technological demonstrator that first flew on 12 July 1990, with bare-bones avionics and without subsystems for weaponry.
  • HA-62-1/V-90A – Prototype version mounted with dual 23 mm autocannons and with a weapons pylon.
  • HA-62-2/V-90B – Final pre-production prototype which saw the weapons pylons strengthened, the 23 mm autocannons replaced with a 30 mm autocannon, and proper sensors added.
  • KaG-62A/Zh-17S – Initial production variant.
  • Kag-62S/Zh-17E – Export variant which has a single 23 mm autocannon, downgraded armor and engines, reduced pylon capacity, no millimeter radar, no HMD/self sealing tanks/downgraded avionics/etc.
  • Kag-62I/Zh-17M – Improved variant which added additional weapon pylons, integrated millimeter wave radar, helmet-mounted optics, and enhanced electronic countermeasures.
