The Spanish artillery units operate 92 35/90 twin-gun anti-aircraft systems. These weapons were acquired in the 1970s and modernized at the beginning of this century to the GDF-007 standard.

The companies interested in the tender have until August 28 to obtain the contract documents and submit their participation requests.
