Motor Sich's MS-500V is a named turboshaft family for multipurpose helicopters in the 3.5–6 t takeoff-weight class. The current manufacturer page distinguishes MS-500V/VA (630 shp takeoff), MS-500V-01/VA-01 (810 shp), and MS-500V-02/-03 (950–1,050 shp), with separate OEI and continuous ratings and dry weights of 160–180 kg. The family identity is retained with lifecycle unknown because the current page does not by itself establish broad in-production or in-service status for every listed variant.
