Integrated electric propulsion better serves future loads

What are the merits of combined gas-and-gas propulsion for a destroyer?

It is a viable arrangement, but integrated electric propulsion is likely the better long-term choice because it can distribute power more flexibly to propulsion and high-energy weapons.

Different gas turbines can be optimized for generation or direct drive, making COGAG a credible mechanical solution. It may have arrived too late to displace integrated electric systems, which offer a more adaptable route. Lasers, railguns, and other power-hungry equipment make electrical distribution a design requirement rather than merely a propulsion choice.
