re: PLAN Type 052 Class Destroyer
What would a 965EM Sov add to such a battle group? Another 052B or 052C will do as well, and not stick out like a sore thumb (lower radar signature).
Character. It's his model fleet after all, and I imagine it would get a little 'boring' to just add another 052B/C or 054A. I would have thought an 051C might have added similar character and also be more realistic, but maybe there isn't a model for it, or maybe Jeff just already have a suitable Sov model, so using it would save him time and money.
In real life, it is hard to see how a Sov would be useful, but I hardly think a Sov will have a larger RCS than the carrier or replenishment ship.
The biggest problem with the Sovs is that there biggest asset - the sunburn, is of no use to a carrier strike group that doesn't want to get remotely close enough to the enemy where the sunburn would be useable.
In terms of AAW or ASW, the Sovs have nothing over the likes of the 054As never mind the 052Cs.
Can the Sovs even network with other PLAN ships using datalinks? Come to think of it, I cannot recall any instances where the Sovs have operated together with other PLAN ships as part of a task force. They always seem to just operate by themselves or with other Sovs, but rarely if ever with other PLAN ship types.
If it is true the the Sovs could not network with other PLAN ships other thank the other Sovs, that may explain why the PLAN has never sent Sovs out on anti-piracy missions. Everyone knows that those missions are prime training opportunities for long range and fleet ops, and it could be that it was felt the training experience would be diminish if one of the three ships was literally not operating on the same wavelength. That seems like a far more sensible explaination than the usual 'the Sovs are so bad that they might not last the duration of the mission without breaking down' reasons others have suggested.
The Sovs are hardly the poster boys of reliability, but it is hard to imagine them being that bad, especially since the PLAN has hardly been pushing them since getting them, so they should still have a lot of miles left on the clock.
