Pion-NKS (14F139)
Pion-NKS (14F139) [KB Arsenal]
The Russian Pion-NKS (14F139) satellites are the naval component of the next generation ELINT satellite system Liana.
As a replacement for both the passive ELINT US-PM and the active radar US-A, they carry both ELINT sensors as well as an active radar.
The Liana system replaces both the Tselina-2 with Lotos satellites and the naval US-PM and US-A with Pion-NKS (14F139) spacecraft.
