MARAD type C3 ships for conversion to desperately needed escort carriers, it was decided in early 1942 to convert four oilers to escort carriers. The conversion took around six months.

The ships were withdrawn from active service shortly after the end of the war. Some of them were kept in reserve and reclassified as helicopter escort carriers (CVHE). All had been sold or scrapped by the early 1960s.
