So I was wondering why the US navy never built any sister ships to the long beach class? Was it because the radar was kind of awkward in practice? Or what? Would love to know.
Cost.
A
lot of new surface ship and missile conversion programs died to bring the Polaris Subs into service. Note that even the original number was supposed to be "45 for Freedom", not the 41 that were built.
Edit: Just to put this into perspective, the US at the time was spending close to 10% of the GDP on defense, and we still couldn't afford everything the Navy was asking for.
