The PPRU-1 is designed to coordinate the actions of regimental anti-aircraft batteries. It integrates under unified command and control various air defense missile or artillery batteries.
Specifications (9S80 Base Model) Radar System (9S80) The PPRU-1 is equipped with the 9S80 radar, which is a digital solid-state circular surveillance radar operating in the centimeter band. :*Detection Range (Air Targets): 40 km. :*Upper Elevation Limit: 5.5°/30°. :*Refresh Period: 5 seconds. The system is also equipped with a "friend-or-foe" (IFF) interrogator and specialized telecode communication equipment for radar data transmission, along with two R-123MT and R-111 radio stations.
Role and Operational Capabilities The PPRU-1 is designed to coordinate the actions of regimental anti-aircraft batteries. It can provide target designation and command to a variety of air defence assets, including:
Self-Propelled Systems: :*
ZSU-23-4 "Shilka," :*9K31M "Strela-1M," :*
9K35 "Strela-10," and :*
2K22 "Tunguska." MANPADS: :*
9K34 "Strela-3" and :*
9K38 "Igla." Key operational capabilities of the PPRU-1 include: :*Conducting air reconnaissance and evaluating the air situation. :*Receiving commands from higher command posts. :*Assessing the combat status and ammunition levels of subordinate assets. :*Issuing tasks and precise target designations to air defence units. :*Organizing air defence for covering troops and facilities.
Operational Effectiveness Studies following the adoption of the 9S80 indicated significant improvements in air defence effectiveness due to centralized control: :*The number of timely processed targets operating at altitudes up to 100 meters increased by 75%. :*The mathematical expectation of engaging friendly aircraft (reducing friendly fire) decreased by 25%. :*The expenditure of ammunition per downed target decreased by 4–5%. :*The intensity of engaging air targets increased by 15–20%. == Modifications ==
