A number of the gunboats underwent two conversions, from a (G) configuration to an (R) or (M). They are listed at the location where each change took place. Thus, an individual ship may be listed twice. Some ships are not listed as their conversion locations are unavailable. Numerous small yards in southern California converted ships and they are identified wherever possible. Many of the shipyards existing in 1944–1945 were in the area between San Diego and Long Beach, California.
Conversions were made in a single yard or in a combination of yards. For instance, LCI(L)s of Group Sixty-Three received their rocket launchers and guns at the U.S. Naval Drydocks, Hunter’s Point, San Francisco. Once the new weapons had been installed, the ships went to several yards in the San Francisco area for further work. The second part of the conversion involved modifying interior spaces to rocket storage compartments. In the San Francisco area, this work was performed by United Engineering, San Francisco; Bethlehem Steel, San Francisco; Moore’s East Yard, Oakland; Hurley’s Marine Works, Oakland; General Engineering, Alameda; and United Engineering, Alameda.

The first LCS(L), LCS(L) 1, was launched by the Lawley yard on 15 May 1944. The last built there was LCS(L) 130, launched on 15 December 1944. Albina launched her first, LCS(L) 48, on 7 July 1944, and Commercial launched LCS(L) 26 on 13 August 1944. The last LCS(L) built was LCS(L) 108, launched by Commercial on 10 March 1945. None of the LCS(L)s underwent conversion as they were purpose-built as gunboats from the beginning.
