IMHO the stupidest feature of this design was the fitting of the twin 8" gun. Why put a high value unit into harms way but putting them into Litoral waters to undertake bombardment, making them more vulnerable to coastal defence and enemy aircraft.
The rest of it's armament makes sense to me, if the SAM system is a point defence system such as ESSM, Sea Wolf, Mica, et al. I also like the all round fire of the Oto 76mm, useful as an AA gun, potentially an effective CIWS and good anti surface firepower, to counter small craft attacking the ship (a la USS Cole). I realise that some of these roles are undertaken by the escort, but I believe in preparing for the worst case scenario. (Hope for the best, prepare for the worst).
