CVE-103 was initially named Alava Bay, 23 September 1943, for a bay indenting the southeastern shore of Revillagigedo Island, northeast of Point Alava, Alexander Archipelago, Alaska; it is located near the southern entrance of the Behm Canal, near 55° 13' North latitude, 131° 07' West longitude (NS0310304).

Renamed Roi, 26 April 1944, in keeping with the policy of renaming CVEs to commemorate victorious battles of the then still ongoing war. Roi is a small island in Kwajalein Atoll of the Marshall Islands (NS0310304a) which was captured by a U.S. naval task force 1 February 1944.

NS0310304b: Roi and Namur Islands attacked by U.S. forces, 1 February 1944. Roi and Namur were two different islands (Roi to the west, closest to camera, and Namur to the east), connected by a narrow neck of land and causeway. After the American occupation, US Navy SeaBees filled the area between the islands by December 1944; the two now joined islands are presently called Roi-Namur with a total area of about one square mile.
