New photos of the Mi‑28NM attack helicopter show a set of previously unseen sensors or antennas marked СВЧ (microwave frequencies from 300 MHz to 300 GHz) installed at various points, including the wing tips, rear cabin area and the tail section. The equipment appears to be a response to recent Ukrainian FPV drone attacks that have downed several Russian helicopters and come close to others, highlighting shortcomings in existing protection systems against low‑cost, small drones.
Earlier reports mentioned a “Moltik” electronic‑warfare system developed by the Gradient research institute for FPV defence, but the devices seen on the Mi‑28NM do not match that system. Analysts suggest Russia may be using an upgraded version of the L‑370 "Vitebsk" suite or testing a completely new active‑defence system specifically designed to counter FPV drones.
