While Coasties were brought to the Pacific to help as landing craft drivers, I don't think any of the landing craft were theirs. They were all Navy.
Landing craft such as these were for amphibious warfare, the "gator" Navy and Marines. The Coast Guard has never been part of the War Department, or Department of Defense as the Navy and Marines are. Amphibious warfare is not the Coast Guard.
Whatever headings are with the photos are those from the site....just so you know ...I couldn’t begin to tell the story or ships and planes one from the other. ;)
