Alaska and Iowa under different design constraints

Iowa's dimensions reflected the Panama Canal, while Alaska's limits came chiefly from the role and scale of a heavy cruiser.

Question

How do Alaska's secondary-armament and aircraft arrangements compare with Iowa's?

Short answer

Both were effective for their intended roles, but Iowa was bounded by the Panama Canal while Alaska was bounded by the heavy-cruiser concept.

Notes

Both ships were effective designs within different sets of constraints. Iowa had to fit the Panama Canal, making infrastructure a direct influence on hull dimensions. Alaska was never going to approach the same beam, while its heavy-cruiser concept limited how much capability could be added before an Iowa offered more. Their layouts make sense only in relation to the physical and doctrinal boundaries imposed on each design.
