The Constellation class won't be doing anything cause it was just cancelled.
Its air defense would have been pretty potent. It had the same Aegis system as Burke. The only limitation is it had the medium range Standard instead of the long range one.
Wrong on both counts. The current plan is to still complete the first two Constellation class ships; only the follow-on purchases were cancelled. And the air defense capability is weak due to an insufficient number of VLS cells.
