Turkey's domestically produced low altitude defense missile system (Hisar-A, 15 km) has successfully completed its final test and will soon go under mass production, a defense official said Saturday.

Defense Industry President Ismail Demir announced that the mass production of the project will start soon.

"Hisar-A low-altitude air defense missile system domestically developed by ASELSAN and ROKETSAN has successfully destroyed the target with 100% accuracy in the final tests," Demir said on Twitter.

Demir's statement comes as Spain is threatening to withdraw Patriot missiles from Turkey over the country's ongoing anti-terror operation in northern Syria.

In the face of growing security threats engulfing its region, Turkey had to rely on Patriot batteries provided by its NATO allies Germany and the Netherlands, which were withdrawn in 2015, and later Spanish batteries took their place at the İncirlik Air Base in Adana.

Hisar air defense missile system was developed by ASELSAN and ROKETSAN under the coordination of the Undersecretariat for Defense Industries (SSM).

The Hisar-A and Hisar-O are expected to be in service by 2020 and 2021, respectively.

HISAR missiles are defense weapons developed to protect military bases, ports, facilities, and troops against air-based threats as well as to meet the needs of the Turkish Armed Forces for a low- and medium-altitude air defense security system.
