Military Computer Systems History : By Bilal At the outset of computer engineering development in the USSR in the 1950s the main attention was concentrated on the creation of computers which could solve complex mathematical problems. Computers then were stationary and intended for successive or batch problem solution irrelatively to the real time and dynamic parameter changes. Later the machines formed the most widespread class of universal computers for various applications. By the late
