Thing is, Langley was never used in a position where it could face combat. We’re deploying Zumwalt *already*.
(Quibble) Langley converted over to an auxiliary carrier and was sunk by the Japanese, so it’s hard to tell what plans the Navy might have had. She was forward deployed with the Asiatic Fleet. The DD-1000’s are being tried out as surface raiders. The crews need t I be trained and the bugs worked out (there are many). They do have large VLS cells, so they are a credible threat on paper.
