Does anyone know if the italian modernization of de la penne class with sm2 missiles went through?
Also, if yes, what system does it use to guide missiles towards the targets, as in midcourse corrections?
i guess any example of non aegis sm-2 system would be good here, perhaps koren kdII class, how are sm2 guided there? Dedicated radio antennas? Guided via search radar? If the latter, how is that achieved given the radar rotates, it should be some track while scan option but it doesnt seem as if many updates per minute would be possible. How many missiles could be guided during midflight phase?

Just what kind of subsystem is used to feed the midcourse correction data to the missiles? How many channels are there? Those are the questions that interest me. It seems ludicrous to me that there is more publicly available data on the modern examples like seaviper/apar/aeagis then there is about NTU system USN doesn’t even use anymore.
It’s even in a wiki on NTU! 😉

The answer you’re looking for is SYR-1. It’s the comms link antenna through which the SM-2 missiles downlink their position to the WDS Mk 14.

Thank you, but nowhere in that text is clear HOW that system works. It mentiones 20 targets are tracked with some old series computer, but it seems to me it is talking about tracking of targets in the skies, not about keeping precise and almost live tracking of X number of targets for which is then data fed to the sm2 missiles fired towards them.

The ship is also equipped with the Raytheon Standard Missile SM-2MR Tartar GMLS Mk 13 missile system for defence against medium-range airborne targets.
SENSORS
The ship’s radar suite includes: Raytheon SPS-52C E-band long-range three-dimensional air search radar; Selex MM/SPS-774 (RAN 10S) F-band air search and surface search radar; Selex MM/SPS-768 D-band air search radar; Selex (formerly Galileo Avionica) MM/SPS-702 I-band surface search radar; four Selex fire control radars for the NA 30 operating at I and J band; two Raytheon AN/SPG-51D fire control radars for the surface-to-air missiles, operating at G and I bands; and Selex MM/SPN-748 navigation radar operating at I band.
