The Voychenko ViS-18 "Bierkut"[a] is a stealth, single-seat, twin-engine multirole fifth-generation jet fighter being developed by Voychenko and Sobchak Design Bureau since 2002 for air superiority and attack operations, produced by the Aviation Industry Corporation of Gorbatov (AVIC). Developed as an answer to the increased use of stealth aircraft by militaries throughout Atlas. It is a product of a ViS program to develop technologies for a next-generation fighter aircraft able to surpass existing fifth-gen fighters, such as the Stasnovan VeK-44, Granzerian V-12, and Vazandian KFZ-9.

The fighter is designed to have supercruise, supermaneuverability, stealth, and advanced avionics to overcome the prior generation and even other fifth-generation fighter aircraft as well as ground and naval defences. The ViS-18 is intended to succeed the VeK-29, Lu-27, and VeK-44 in the Proletarian Liberation Army Air Force, to which it entered service with the PLAAF in 2018, having entirely rearmed the 1st Guards Aviation Regiment with ViS-18s by mid-2020.

The prototypes and initial production batch are to be delivered with a highly upgraded variant of the Stasnovan Krasna AL-50FA, Sobchak AL-50M2, as an interim powerplant while an advanced clean-sheet design engine, currently designated the Sobchak S-50, is in final stages of development and expected to be available after mid-2020s. The aircraft is expected to have a service life of up to 40 years.
