This is a trophy war in Ukraine.

Multi-channel military electronic control/signal processing board.

What we see here is a Soviet electronic board for military or aviation use, assembled using 564-series CMOS microcircuits in military-grade metal-ceramic housings. These boards were used in control systems, automation systems, and logic signal processing. This is not consumer electronics, but an example of reliable Soviet engineering, designed to withstand vibration, temperature fluctuations, and long-term operation.

Purpose (most likely):

signal processing unit

generation of control pulses

intermediate module in:

aviation equipment

military measuring equipment

radar or navigation systems

automated control/protection systems.
