Interfax reports that Russia plans to construct a missile early-warning radar station in Crimea in 2019, according to a Crimean security source. The new radar station is to have the capability of tracking ballistic and cruise missiles from long distances. The Interfax source identified the planned location for the high-tech radar installation as in the vicinity of the port of Sevastopol — home to Russia's Black Sea fleet. It's not the first time plans for the radar have been announced. It was previously described as a new generation radar Voronezh-SM designed by one of the largest defense contractors in Russia, RTI Systems. 

A prior TASS news agency report which first hinted in 2017 that the system could be operational gave a timeline of "in the coming years" — suggesting either Russia will scramble to complete the project amid the current crisis or officials could be merely touting future plans to deter encroachment by NATO.
