Due to the lack of the required number of dynamic protection elements (ERA), JSC "NII Stali" proposed using non-explosive reactive protection (NERA). This was reported by the Telegram channel "Military Informant".
NERA is a metal container from a dynamic protection element, which, instead of standard ERA such as 4S20 and 4S22, is equipped with 2-mm plates made of structural steel, between which a 6-mm plate of organic glass is installed, tightly wrapped with tape.
Tests against PG-7L and PG-9S grenades (the main warheads of FPV drones) showed that when equipping ERA boxes with NERA, resistance of 71% of the standard 100% was obtained.
The resistance of the side elements when equipped with NERA reached 92%, while the turret modules with NERA showed 69% resistance. At the same time, filling the blocks with sand instead of ERA or NERA elements was also tested, which sometimes reached a resistance of 40% of the reference.
The most effective way to equip the навесной kit of dynamic protection and dynamic protection blocks is their standard equipment with ERA, and an acceptable way is a combined equipment of ERA and NERA.
Earlier www1.ru reported that a Varan-3 kamikaze bomber drone has been developed for the military, the first test footage has appeared.
