Testing six-inch dual-purpose guns on a Brooklyn hull

Would an Atlanta-like cruiser on a Brooklyn-class hull with six-inch dual-purpose guns be worth building?

A trial group of three or four ships could test the concept before the navy committed to mass production.

The combination could be useful, but it did not justify an immediate full production run. The six-inch dual-purpose mount would have to demonstrate that it worked in service. A three- or four-ship trial class could test the concept and expand production only if the results justified it. Limited procurement can control technical risk.
