Development
The P-20 development was started in 1946 when State Federal Order of the Red Banner Research Institute Number 20 (now called All-Union Scientific Research Institute of Radio Engineering or VNIIRT) was given the task of developing stationary and mobile early warning ground control and interception radar for the Soviet Air Force. The stationary radar would go on to become the P-50 but the mobile radar was to become the P-20. A design would go on to spawn a number of successors including the P-30, P-35 and P-37 radar.
The P-20 would become the first Russian radar to use the decimetric wavelength, the first prototype being created in 1947, a factory test unit 1949. By 1949 the radar had completed state trials and was accepted into wide service within the Soviet airforce, the designers of the P-20 would go on to be awarded the State Prize of the USSR in 1950 in recognition of the achievement.

Famous quotes containing the word development:
“On fields all drenched with blood he made his record in war, abstained from lawless violence when left on the plantation, and received his freedom in peace with moderation. But he holds in this Republic the position of an alien race among a people impatient of a rival. And in the eyes of some it seems that no valor redeems him, no social advancement nor individual development wipes off the ban which clings to him.”
—Frances Ellen Watkins Harper (1825–1911)
“Understanding child development takes the emphasis away from the child’s character—looking at the child as good or bad. The emphasis is put on behavior as communication. Discipline is thus seen as problem-solving. The child is helped to learn a more acceptable manner of communication.”
—Ellen Galinsky (20th century)
“John B. Watson, the most influential child-rearing expert [of the 1920s], warned that doting mothers could retard the development of children,... Demonstrations of affection were therefore limited. “If you must, kiss them once on the forehead when they say goodnight. Shake hands with them in the morning.””
—Sylvia Ann Hewitt (20th century)
