Earlier this month, russia's PJSC Motovilikha Plants presented its developments to russian dictator Putin.
This exhibition could be described as the company's "graveyard of projects," featuring models that exist only as prototypes or single units and are showcased year after year without results.

For instance, a video from the factory showed the forgotten Derivatsiya-PVO system, built on the BMP-3 infantry fighting vehicle chassis, which in theory was meant to replace Soviet-era systems like the Shilka and Tunguska in the russian occupation army.
This system, or rather a prototype, was first presented in 2017 at the Armiya forum. In 2022, with the start of the full-scale invasion of Ukraine, the russian defense industry faced a shortage of chassis, as they were needed at the front for their intended role, and many were being lost in combat.
According to the developers' statements, the Derivatsiya system, armed with a 57-mm 2A90 gun, is capable of shooting down targets at a range of up to 6 km and at altitudes of up to 4.5 km. The system was designed for a rate of fire of up to 120 rounds per minute, with an ammunition load of 148 shells. At the same time, much suggests that Russia planned to take the 2A90 barrels from decommissioned Soviet S-60 anti-aircraft guns.
The vehicle took part in parades. In May, the 2S38 Derivatsiya-PVO appeared not in Moscow, but in a parade in Nizhny Novgorod.
As of today, no information is available about the serial production of this weapon, and the vehicle has yet to appear on the battlefield.
