In 2015–2016, Russian maintenance, repair and overhaul company 150 ARZ (controlled by Russian Helicopter Holdings) was involved in the refurbishment and life extension of an undisclosed number of Mi-24P Hind-F helicopter gunships sold to Angola by Rosoboronexport. Work took place at the company’s Lyublino facility in the Kaliningrad enclave.
The Hind-Fs, drawn from Russian military stocks, had to undergo a deep refurbishment with the 150th ARZ before delivery.
Details emerged in another announcement that Rosoboronexport delivered four refurbished and life-extended former Russian military Mi-24Ps to Sudan. All four Hinds were overhauled by maintenance, repair and overhaul company 410 ARZ (also controlled by Russian Helicopter Holdings) at its Chita facility in Eastern Siberia.
