Other Auxiliaries
(AGB, AGC, AGDS, AGEH, AGER, AGF, AGM, AGMR, AGP, AGR, AGTR)
Most recent update: April 6, 2015.
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.
If you have an addition or correction for this page, please send it in.
