Identifying the ships photographed with Missouri and Alaska

What is the light carrier in the photograph with Missouri and an Alaska-class cruiser?

The accompanying description identifies it as the escort carrier USS Croatan and also lists several destroyers in the scene.

The smaller carrier is difficult to identify from the image alone. The accompanying description names her as the escort carrier USS Croatan. It also lists two Fletcher-class destroyers at the pier and an older destroyer moored outboard. The uncertainty followed by a captioned identification shows why provenance matters in crowded naval photographs.
