During MSPO 2015, 23rd International Defence Industry Exhibition 2015  was shown a modernized air defense systems 2K12-2D KVADRAT-2D by  Ukrainian state company Ukroboronservice.
In present conditions of technologies fast development there is a possibility for multiple increase of combat effectiveness of any old-type Air Defense Missile System (ADMS) with much less expense than during buying of new examples with comparable characteristics.
During modernization of AAMC 2К12Ðœ1 “Kvadrat-Ðœ1” up to level AAMC “Kvadrat-2D” it will be solved the following problems:
- Increase of operation terms of the modernized systems for the term of not less than 15 years.
- Replacement of the analog radio-electronic equipment to digital one:
– in SURN 1С91Ðœ1 – up to 80%,
– in SPU 2П25Ðœ1 – up to 70%. - Increase of mean time between failures of the modernized radio-electronic equipment – up to 1,500 hours.
- Increase of combat capabilities of a complex (increase of noise protection, automation of processes of air targets detection, targets designation, etc.).
- Simplification of technical operation (reduction of maintenance scope, increase of repair ability).
- Reducing of SPTA quantity and nomenclature on 70%
During MSPO 2015, the Ukrainian company said that they are able to increase the service life of the system by 15 years by replacing up to 99% of old components with new parts. It has a declared increased reliability up to 1,500 hours between major failures. Several elements have been digitalized. Â While the new version is still able to engage only one target simultaneously, with the upgrade its operational range increased from 50-70km (against a fighter at the altitude of 7km). The new system is able to detect cruise missiles at a minimum of 21Â kilometres.
