The Great Red Sea Turkey Shoot proves that drone and ballistic missile proliferation are going to be increasingly common. In short, the need is for a prolific second tier AAW escort, which pretty much sums up the Constellation. Or in other words, more a successor to the Perry class than the Knox class. Aside from the capable active towed array, the Constellation doesn't even have a hull sonar, not even a modest one for mine avoidance.
It's worth noting the Constellation has has low speed electric drive but isn't IEP. As we all know, IEP was initially a disaster in terms noise aboard the Type 45 Destroyer. There's nothing wrong with hybrid diesel electric and direct drive gas turbine concept and it's definitely easier to optimize for ASW platforms. I expect a huge fuel savings over the Burkes, but I do have doubts about the compatibility of the Constellations with 20knot fleet cruising speeds, when the electric propulsion is optimized for a few knots less than that. Moreover, the single LM2500 not only limits the top speed but flexibility. I might be wrong and the FFG-62 might make over 20 knots on electric and 29 knots on the gas turbine like the old FFG-7s which did function as fleet escorts. I just hope there isn't a big efficiency speed gap. The British Type 23s could only make 15 knots on the electric motors but having 2 gas turbines gave them greater flexibility and a respectable flank speed..
