USS Atlanta (CLA-1944)
Operations with the Omaha class AA conversions, sold the US Navy on the type. As
AA escorts and destroyer killers they were exceptional. A slightly bigger, more
capable ship was envisaged with one more turret than the Omaha type and for the
first time in ten years, the Atlanta class would be completed with torpedo
tubes. Originally designed with four sets of torpedo tubes, before the Atlanta
was even near completion the forward sets had been removed to offset the radar
that had been added to the masts and directors.
These ships fought topweight issues all their careers. The original design had
eight twin 5" with an extra pair fitted beside the aft superstructure. These
were early deletions as the extra weight so far out on the beam of the ship
would have them rolling on wet grass (as the saying goes). They were replaced
with an extra pair of twin 40mm.
Despite all the issues with the ships, the men who crewed them, liked them.

The topweight problems with the class meant that they did not last long
in service past the end of WW2. The ships did not have the size to allow them to
be upgraded into the missile age that the other cruisers of the time had.
