P-40 radar at Park Pobedy, Saratov
|Country of origin||Soviet Union|
|Type||Early Warning/Target Acquisition|
|Range||370 km (230 miles)|
The P-40 was developed by Scientific Research Institute #208 GKRE, which later became known as NIIIP of Minradioprom, OKB-588 (later Lianozovskiy Electromechanical Plant, LEMZ) also assisted in the production of the prototype.
Between the 1966 and 1968 the radar was upgraded, increasing the range of the system. Later, between 1969 and 1970, the radar's range was again improved in addition to achieving better reliability.
The P-40 used the AT-T artillery tractor with tracked chassis, fitted with a 12-cylinder 4-stroke diesel engine with an output of 342 kW (465 hp) and producing a top speed of 55 km/h. The P-40 had a crew of 6 and a total weight of 35 tons, the radar being powered by a gas turbine running 400 Hz generator.
The radar uses an open frame truncated parabolic antenna with a stacked antenna feed. The radar antenna is mounted on the truck used to transport it giving excellent mobility, the radar capable of being folded for stowage during transit. Azimuth was determined by mechanical scanning while the angle of the target is determined from within which beam of the antenna stack the target is detected, the radar does not carry a secondary antenna for IFF.
The P-40 was operated by the Soviet Union from 1963 and though it has since become obsolete it was passed down to successor states after the fall of the Soviet Union.
