How Should The Navy Power Its Next Destroyer? (From Forbes)

The Navy has begun developing a successor to its Arleigh Burke class of destroyers. It is designated DDG(X), with the “X” underscoring that the design has not yet been fleshed out. The sea service wants a warship with much greater range and fuel efficiency, and integrated electric propulsion. What isn’t so clear is the right type of engine to generate all the electricity needed for propulsion and other functions. Gas turbines are the most efficient at peak power, but diesel engines are more efficient at lower and medium speeds. China and Britain have opted for diesel-electric designs on their surface combatants. Will the U.S. Navy do the same? I have written a commentary for Forbes here.
