Space based recon and targeting Liana finally gets its active radar and imaging constellation (passive Lotos satellites are already in orbit) of Pion-NKS into the final stretch with the launch of KOSMOS-2550 on 25 June 2021.
There is one detail, however, which needs to be explained to laymen–Liana does not “guide” missiles. Missiles are guided by onboard inertial navigation system and correct their path using a wide variety of means from GLONASS to celestial navigation means, to, in case of land attack missiles by means of TERCOM and DSMAC. Liana provides the most important service: it detects the target(s) and “issues” coordinates (targeting data) which allows the guidance of the salvo to the accurate targets’ vicinity in which missiles are capable to detect (refined search–dorazvedka) and lock on the target(s) with their seekers, whatever those might be ranging from radar to optronic or mixed. Targeting is the most important thing and Liana is capable to deliver it already, once all Pions are in orbit, well we may only speculate how much territory they will cover but those will undoubtedly be the most important theaters of operations of US and NATO navies. I guess training of TU-22M3s and MiG-31Ks at Khmeimim base has a lot to do with Liana finally coming online in full force. Recall that X-32 has a range of 1000+ kilometers while Kinzhal has a range of 2000 kilometers etc. You know, Mediterranean and all. Recall this from three years ago:
We may also thank our wonderful friend Evald (didn’t see him in a long time) who drew for us great illustrations:
