Yugoimport KUB-SM Surface-to-Air Missile gets digital makeover.

Yugoimport SDPR J.P. has undertaken a comprehensive modernization of the KUB-M2 surface-to-air defense missile system, transforming it into the KUB-SM. Originally a Soviet low to medium-level air defense system designed to protect ground forces from air attacks, the KUB-M2 is composed of multiple modules including radars, command and control stations, and missile launchers. This upgrade not only breathes new life into the Cold War-era system but also equips it with modern digital capabilities, making it a serious asset in today's complex aerial warfare landscape. The revamped KUB-SM was showcased at the Partner 2023 salon in Serbia, signaling its readiness for the modern battlefield.

The modernization of the KUB-SM system is a multi-faceted endeavor that touches on several key areas. At the heart of the upgrade is the Fire Command and Control Station, known as SKUV-SM - KBU. This command system has been thoroughly revamped to incorporate modern information technology, thereby significantly enhancing its efficiency.

The system's radars, specifically the Surveillance and Acquisition Radar (OAR-SM - 1RL128) and the Height Finding Radar (RMV-SM - PRV-16), have also received substantial upgrades. These improvements have led to increased sensitivity, better target visibility, and overall enhanced tactical and technical characteristics.

Another critical component that has been modernized is the Surveillance and Guidance Station (RSTON-SM - 1591). This station has been optimized to improve the system's target tracking accuracy, making it more effective in real-time operations.

The result of this extensive modernization is a new, digital Air Defense Missile System (ADMS) with a maximum slant range engagement of 25 km. The system now boasts several advanced features. These include improved radar characteristics that allow for better tracking of targets in cluttered environments and at low altitudes. Additionally, the system offers a more comprehensive and clearer image of targets in airspace, both on radar and command post displays.

One of the standout features of the modernized system is the ability to remotely control the radar from the command post. This adds a layer of operational flexibility that was previously lacking. Moreover, the system's reliability has been increased, and maintenance costs have been reduced through the replacement of outdated components with new solid-state technology.

The KUB-SM system offers a comprehensive suite of operational advantages that make it a standout in modern air defense. These advantages include the ability to directly connect radar stations P40-SM, RSTON-SM, and SKUV-SM to the AD Operations Center, streamlining the command and control process. This direct connection allows for the swift transmission of target data from the command post to RSTON-SM, resulting in more accurate and faster directing of the tracking radar to the target.

Additionally, the system enables the direction of tracking radars and self-propelled launchers without the need to activate its own surveillance radars, reducing its electronic footprint. This feature is particularly beneficial for enhanced night operations and operations in conditions of low visibility. Furthermore, the system requires a shorter time for radar emissions, offering better protection against anti-radar missiles. On the reliability front, the system has reduced maintenance costs due to the replacement of outdated components with new solid-state technology.
