Aerotechnica upgrades 'Guideline' for an unidentified customer

The Ukrainian company Aerotechnica has developed a new modernisation scheme for the S-75 (SA-2 'Guideline') surface-to-air missile (SAM) system, and has begun upgrade work for a currently unnamed customer.

The revised configuration is designated S-75M3 Volkhov-M3 and is intended to extend the life of the system for a minimum of 15 years. It introduces improved automation intended to boost combat efficiency and, according to the manufacturer, will increase combat survivability, provide additional resistance to jamming, and offer a mean time between failure (MTBF) of up to 1,500 hours.

In various configurations, the S-75 system is still in service with many countries around the world, most of whom lack the financial resources to procure an all-new replacement. Some operators plan to keep the S-75 in service for at least another decade, representing a potential market for the new upgrade.

The modernised S-75M3A system offered by Aerotechnica consists of:

- a newly-developed UV-A fire-division combat control cabin;

- a modernised PV-A transmitter-receiver cabin with antennas;

- a missile fire battery;

- P-1V, P-2V and P-3V trailers for transporting the antennas; and

- a PRM mobile repair workshop.
