I was wondering primarily because GT/diesel electric combinations are being used for the new class of LHDs now being built (Wasp class and America class). But, reflecting on what you wrote, they are not quite half the tonnage as Nimitz-class carriers and do not have the same launch and high speed transit requirements.
Thanks for taking time to answer my questions.
Nah I love to talk about this stuff. GT/D has likely come a long way since I was around in the mid-90s, but I do have some concerns for the LHDs going that route. Likely be ok though, just an old bias on my part likely.
