This is me shaking my head in frustration and sadness.
Don't feel too bad. It was an interesting idea that generated four pages of discussion. While I still think carrier-based fighters and Talos could the job you want to modify the
Alaskas to do you might try mounting the Sea BOMARC on another ship. I don't think putting it on an
Essex would help much, the standard displacement of the
Essex class and the
Alaska class are about the same. Maybe a battleship ala the
Mississippi.
Maybe you should try a "distributed" system. As noted above the DER radar pickets would be important. Think about putting the SAGE gear on another ship. The SAGE control ship could then control all three modified
Alaskas at the same time as well as fighters.
