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:
“Sleep hath its own world,
And a wide realm of wild reality.
And dreams in their development have breath,
And tears, and tortures, and the touch of joy.”
—George Gordon Noel Byron (1788–1824)
“I hope I may claim in the present work to have made it probable that the laws of arithmetic are analytic judgments and consequently a priori. Arithmetic thus becomes simply a development of logic, and every proposition of arithmetic a law of logic, albeit a derivative one. To apply arithmetic in the physical sciences is to bring logic to bear on observed facts; calculation becomes deduction.”
—Gottlob Frege (1848–1925)
“The proper aim of education is to promote significant learning. Significant learning entails development. Development means successively asking broader and deeper questions of the relationship between oneself and the world. This is as true for first graders as graduate students, for fledging artists as graying accountants.”
—Laurent A. Daloz (20th century)
