Construction of the new early-warning radar at the Olenegorsk site began in the spring of 2016. At this point it's just a hole in the ground and the flat terrain makes geolocation rather difficult. But the new site is probably not far from the old Dnepr/Daugava site.
This is probably the last in the series of new early-warning radars that Russia will build in the coming years. At least that was the plan in 2013. It appears that the new Olenegorsk radar will be of the Voronezh-VP type, similar to those built in Mishelevka and Vorkuta.
