"Machine Building Design Bureau" enterprise also specializes in development of torpedo weaponry for surface ships, passive jamming
devices and many other weaponry.
is another appellation for chaff while active-passive refers to combining aircraft survivability equipment (ASE) jamming with chaff by, for example, reflecting the ASE jamming signal off chaff, thereby misdirecting a jamming antiradiation missile (ARM).
Its aircraft can be fitted with internal and external EW equipment for threat simulation and active and passive jamming
systems covering a wide spectrum of frequencies, and can simulate the specific radar signatures of potential bad guys.
