Russia’s New 2S38 57mm Air Defense Gun Appears as U.S. SGT Stout and German Skyranger Advance
New imagery has brought attention to Russia's 2S38 Derivatsiya-PVO self-propelled air-defense vehicle, which mounts a 57-millimeter automatic cannon on a BMP-3-derived tracked chassis. The design is intended to defeat drones, helicopters and other low-altitude targets using electro-optical detection and programmable ammunition, with Russia advertising engagement capabilities beyond those of smaller conventional autocannons. Its reported appearance during a 2026 exercise does not independently establish the number of vehicles delivered or their combat performance. The system is being assessed against a wider movement toward mobile gun-based air defense, including America's SGT Stout and Europe's Skyranger families.
