So, RV-SB is low altitude fuse, RV is high altitude fuse, K3 is automatic destruction of missile by the system. And RV and RV-SB both arm the missile straight after launch? They just have different fuse sensitivities, correct?
They are mostly the same as we have with the Volhov, the difference, is that the Neva can select them automatically.
Neva / Volhov
RV / STAN
RV-SV / USU-NLC
K3 / K3
