Submarine Tenders



Alaunia, Artifex and Ausonia
These three ships have tended to the D1/9 class fleet subs and various R class subs since their construction in 1916. Alaunia originally tended to the D1/9 class subs and later the newer R-74 class subs. Ammunition, torpedo and fuel load out vary depending on the class of subs they tend to. The extra bunkerage for submarines is not usually used for full refueling as fuel capacity is not great so these tenders are usually accompanied by a small tanker. These ships have a hoist position on the bow used to lift subs partially out of water resulting in the use of a clipper bow and a sturdy bow sprit.
