Ryazan State Instrument Plant
The plant specializes in production of airborne radio equipment for the needs of civilian and military aircraft: airborne weapons control radars for Su-27, Su-30MK, Su-35, MiG-23 and MiG-29 aircraft; slit-type and phasetype antenna systems; rnultimode airborne radio transmitters of high out- put: multimode receivers. The plant produces and sells: Zarya UNF radio stations; Pereval radio relay lines; ELKOM electronic telephone exchange; analog multichannel and transmission systems for PO-420, PO-120-type multichannel telephone communication; telemetry, remote control and data transmission systems; SET electric power meters; Fora welding devices; URBP level meters/regulators; DMPK differential pressure transformers; medical equipment; consumer goods.
State Ryazansky Instrumental Plant was established as a manufacturer of radio-electronic equipment for military airplanes. Currently, it produces armament control systems for military and civil airplanes. It also manufactures fine mechanics, telemetry, computer facilities and medical equipment, including a popular indicator of inner-eye pressure for ophthalmic use.
The Ryazan State Instrument-Making Enterprise (GRPZ) is the largest instrument manufacturer for the aircraft industry in Russia. In 1919 it was set up as a woodworking factory, with the first order for the defence industry placed in 1935. Since the 1950s its orientation has changed: in collaboration with leading scientific and engineering organisations it began producing airborne electronic equipment for civil and military aircrafts.
Having begun with the production of tube radars for fighters, the factory has for several decades been in the highest echelons of complex defence organisations as a specialised enterprise producing weapon control systems, including radar installations for air forces. Using its hi-tech facilities, GPRZ equips and modifies weapon-control systems for fighters such as the MiG-29 (NATO: Fulcrum) and Su-27. In co-operation with the aircraft plants, it is active in implementing the 1997-2002 contracts for the licensed delivery of SU-27 to China and SU-30M to India and updating the MiG-29s previously delivered to Malaysia. It is also engaged in supplying replacement parts and in repairing delivered equipment.
In May 2002 the Aerokosmicheskoye Oborudovaniye Corporation set up a working group and tasked it to draft technical and organizational proposals concerning development of on-board equipment for the fifth-generation fighter plane. It has started financing the design of a radar, on- board calculator and other equipment for the future plane. The work involves the enterprises that have not become part of the corporation but are expected to do so in the near future. Among them are the Ryazan instrument engineering plant and R&D Institute of Instrument Engineering.
