The Space Forces is planning to add a new early-warning radar to the current radar network, although maybe only in a test mode. According to the commander of the Space Forces, the new radar will complement the existing seven sites and will be a modular "high degree of readiness" facility, which does not require extensive preparation of its deployment site - "we just needs a football field where we could bring a few containers with the hardware".
It seems that the new radar will be deployed near St.-Petersburg, where it could cover the gap in coverage created after liquidation of the early-warning radar in Skrunda, Latvia. The Volga radar in Baranovichi, Belarus, cannot close this gap on its own.
The concept of a portable "high degree of readiness" early-warning radar has been discussed for some time in Russia and it seems very attractive - why build expensive behemoths like Daryal when you could put a radar on virtually any parking lot? There is a problem, though. The main parameter that describes a search capability of a radar (which is exactly what an early-warning radar is supposed to do) is its "potential" - the product of mean emitting power to the antenna area. Of course, clever engineering could go a long way, but you would still need a lot of power and a big antenna. The more it will be interesting to look at the new radar when it's deployed.
