Another organization working on a "better" An-2 is SibNIA (Siberian Aeronautical Research Institute) in Novosibirsk, Russia. In this version, the An-2MS (An-2MC in Russian) and later usually referred to as the TVS-2MS), the radial engine was replaced by a 1,100 hp Honeywell TPE331-12UHR turbine, driving a five-bladed Hartzell propeller. The first An-2MS/TVS-2MS was first flown on September 5, 2011 and by 2015 well over fifteen examples had been delivered by SibNIA and Rusaviaprom JSC, all built, from existing An-2 airframes retaining the An-2 wings and tail feathers.

SibNIA went a step further and also developed an upgraded An-2 with an entirely new composite construction high-lift, high-aspect-ratio wing. This new wing was first tested on an An-2MS which flew as a high wing monoplane. The aircraft, designated TVS-2-DT, first flew in December 2014 and had the TPE331 engine and old style tail. It then received curved wingtips on the upper wing and a new lower wing with wingtips acting as interconnecting struts. In this guise it flew on June 10, 2015, initially also with the old tail, but this was soon replaced by a new design larger and squared vertical tail as shown in the photo.
