SA-6 (2K12 KUB/KVADRAT) is a mobile low to medium-level SAM system. System core consists of radar vehicle and four missile launchers. SA-6 system is still an efficient weapon, although its use is seriously limited by ageing equipment electronics. The original system design and technology are very demanding to operation, maintenance and repair.
Highly appreciated SAM system capabilities, namely vehicles mobility and missile performance, suffer from aging radar electronics and lack of superior command and control network interface.
RETIA, a.s. proposes an SA-6 upgrade including radar vehicle SURN, missile launchers 2P25 and replace of 3M9 missiles including new loading vehicle. This upgrade prolongs system lifetime, increases combat efficiency and decreases operators load. The integrated logistic support is proposed to allow efficient use of upgraded system for the whole lifetime. Proposed upgrade replaces outdated communication equipment with new means. Analogue signal processing and displays are replaced by new digital signal and data processor and new high resolution LCDs.
Upgraded system design is ECCM aware to improve the ECM resistance. Original Kremnyj equipment is replaced by a new, NATO compatible, fully integrated IFF system.
An upgraded original day vision equipment can be expanded/ replaced by night vision one, while both can be supplemented by an optical tracker. Upgraded system is fully compatible with today's C2I systems. Communication means could depend on customer requirements. The upgrade design carefully considers reliability, availability and easiness of repair issues. Proposed upgrade focuses on key performance and reliability bottlenecks of original system.
System's upgrade includes complete replacement of surveillance and fire control radar electronics, new communication means and new operators' workstations.

1S91 "Strait Flush" Upgrade SURN CZ Description
SURN vehicle upgrade starts with repair of chassis and superstructure. The original equipment is subsequently replaced by new subsystems and cable trees. New units are installed into modified original frames. This huge replacement allows optimization on system level, performance and reliability improvement.
Commander's and fire control radar operator's consoles are designed to reduce complexity of operation and the operators´s load. Operators do decision and setting tasks, while routine tasks are performed by software. All units include built-in test equipment (BITE) for easier maintenance and repair. All BITE reports are collected and presented on commander's console.
The extended SURN CZ functionality enables replacement of KPC vehicle
The modernized SA-6 system successfully attended on Live Fire Exercise in 2001, 2007 and 2009.
2P25 Upgrade SPU CZ Description and Missile Replacement

Integrated Logistic Support
Replacement of original 3M9 missiles
- ASPIDE 2000 Missile (evolution of RIM-7 family)
- Medium-range semi active guided missile
- Fully all-weather day/night capability
- X-band semi-active seeker
- Multi Threat Capability
- Intercept up to 20km range
- Total shelf life is 24 years
- Field Proven (over 700 firings)
The SA-13 „Gopher" (S-10 Strela) is self-propelled VSHORAD surface-to-air missile system, intended for firing of the low/medium-level air targets. Manual operation and original incompatible communication, navigation and identification means make impossible to fulfill today's requirements imposed upon this kind SAM systems.
Submitted modernization consists of
- Up-to -date radio and line communication interface to link system with any C4I Center
- Commander terminal
- Automatic target handover into missile fire
- Control system
- Up-to-date IFF Mark XII interrogator with new antenna
- Hybrid INS/GPS navigation system
The air picture information that is delivered from external radar data source by means of the wire or radio link is depicted on the Commander terminal. The Commander terminal is supported by hybrid navigation system. The target clicked for fire is automatically aimed and the target identification is ultimately verified just before missile launch.
The modernization upgrades SA-13 SAM system fire effectiveness, shortens reaction time and minimizes thread of friendly firing.
SA-8 „Gecko" (9M33 OSA AK/AKM) is a mobile short range SAM system with command missile guidance. System employs all sensors and missile launcher on one amphibious off-road vehicle.
The highly appreciated efficiency of SAM system based on extremely high mobility and performance of missiles suffer from aged radar electronics and lack of integration into AD command systems.
The severest limitations of original system are:
- Outdated communication subsystem
- Obsolete radar signal and data processing
- Lack of electronic protection functions (ECCM)
- Limited capabilities of analogue indicators
- Incompatible IFF system
- Low reliability
To achieve up to date system performance and extend lifetime is necessary to upgrade functionality and reliability bottlenecks of radar system. The scope of upgrade can be modified upon user's requirements, while some essential subsystems are mandatory.
Proposed upgrade of SAM system's radar achieves interoperability with air-defence command and control systems, increase system combat performance and reliability. The proposed upgrade includes (in all channels of surveillance and fire control radars):
- New microwave circuitry
- New high performance all solid-state receivers
- New transmitters
- New adaptive radar signal processing
- Upgrade of optical channel (fire control radar)
- Replacement of original analog indicators by new colour displays
- Up-to-date Mark-XII compatible IFF interrogator (including antenna)
- New fire control computer, missile tracking receivers and signal processor, upgrade of missile command link (coder unit)
- New tactical VHF transceivers for voice communication and data exchange
- New digital intercom
- Data recorder and integrated simulator means
- EMC filters avoiding unwanted emission in spurious and out of the band domain
- Overhauling of original special electronics preserved in system
Suggested upgrade can be gradually structured depending on user requirements, military authority policy, budget priority, etc.
