Upon commissioning, DYNAMIC was assigned to Commander Destroyer Squadron EIGHT as USS AFDL-6 in San Diego, CA. In April 1962, DYNAMIC was deactivated, and in August 1962, reactivated for transfer to Little Creek, VA. On 5 September 1962, DYNAMIC was towed by USS CHICSAW (ATF-83) to the Panama Canal for further transfer to Little Creek by USS SHAKOR (ATF-162) on 23 September 1962. DYNAMIC arrived at Little Creek on 01 October 1962, and presently operates under Naval Surface Force Atlantic, Readiness Support Group, Norfolk, Virginia.
The dock was intended primarily for advanced base operations in areas which may be remotely separated from any permanently established shore-based installation.
In part it is self-sufficient in that it carries its own source of power, supplies and provisions as well as providing for ship repair services. Personnel, repair barges and other floating equipment are often permanently assigned to the dock and becomes an integral part of it as an operating unit.
DYNAMIC is suitable for docking vessels of the mine countermeasure (MCM) and (MHC), patrol craft (PC), yard tug (YTB) and other vessels of a similar size. Obviously, smaller vessels can be docked in this dock, sometimes in multiple docking arrangements.
Presently DYNAMIC operates as a shore dependent dock, providing regular and emergency docking availability, and sandblasting services for Commander, Naval Surface Force Atlantic operating units and various support craft.
