Naval auxiliary ships carry out a variety of missions in support of combatants. Along with destroyer tenders, the submarine tenders are the largest of the active auxiliaries. Their crews are formed mainly of technicians and repairmen. The Hunley class was configured especially to service FBM submarines. The Holland was in Guam from 1993 through 1996, prior to decommissioning in May 1996 in Bremerton WA.
