Concept
Depot ship
Résumé
A depot ship is an auxiliary ship used as a mobile or fixed base for submarines, destroyers, minesweepers, fast attack craft, landing craft, or other small ships with similarly limited space for maintenance equipment and crew dining, berthing and relaxation. Depot ships may be identified as tenders in American English. Depot ships may be specifically designed for their purpose or be converted from another purpose.
Depot ships provide services unavailable from local naval base shore facilities. Industrialized countries may build naval bases with extensive workshops, warehouses, barracks, and medical and recreation facilities. Depot ships operating within such bases may provide little more than command staff offices, while depot ships operating at remote bases may perform unusually diverse support functions. Some United States Navy submarine depot ships operating in the Pacific during World War II included sailors with Construction Battalion ratings to clear recreational sites and assemble buildings ashore, while the Royal Navy mobile naval bases included specialized amenities ships to meet recreational needs of British Pacific Fleet personnel.
Services provided by a depot ship depend upon whether typical client warship missions are measured in hours, or days, or weeks. A warship crew may be expected to remain at their stations for missions measured in hours, but longer missions may require provisions for dining, sleeping, and personal hygiene. The crew of small warships may carry individual combat rations and urinate or defecate from the weather deck. Longer missions typically require storage provisions for drinking water and preserved food, and some resting area for the crew, although rest may be limited to a sheltered spot to sit or recline. Cooking may be limited to warming food on an exhaust vent, and buckets may be used for bathing, laundry, and sanitary waste. Habitability standards vary among navies, but client warships large enough to include a head, bunks, a shower, a kitchen stove, refrigerated food storage, a drinking water distillation unit, and a laundry require little more than medical and repair service from a depot ship.
