Putting a VLS and an AEGIS system on a CGN-42 would have pretty much made them into what the CSGN was supposed to be. Too bad some brilliant admiral didn't come up with that bright idea. LOL
It was an idea that was floated around but ultimately expense got in the way (specifically the operating expenses of CGN-42). Remember, this is why we got CG-47.
Yeah, as with most good military ideas, the politicians often get in the way.
Politics didn't get in the way, money killed it. Despite what a lot of people think giving the military-industrial complex a blank check is inefficient and to put it bluntly, stupid.
To give it some perspective, that's exactly what the Soviet Union did.
