Other Auxiliaries
(AGB, AGC, AGDS, AGEH, AGER, AGF, AGM, AGMR, AGP, AGR, AGTR)
Many auxiliaries were created by converting existing ships; others were built new but starting with an existing design; the balance were both designed and built for their purpose. There are some gaps in the data, particularly for the conversions.
