Other Auxiliaries AGB, AGC, AGDS, AGF, AGM, AGMR, AGP, AGR

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. In this table, AGB 1-6, all AGC excpet 4 and 6, AGEH 1 and AGP 4-20 represent the second and third categories - the ships that were purpose-built. There are some gaps in the data, particularly for the conversions. Comments or queries, please email info@navalmarinearchive.com.
