Rubi Class Depot Ship



The Rubi class tenders primarily built with submarine support in mind; existing tenders built by the then-Island Commonwealth Navy are small, old, and not really adequate for the task.

Of note, the tenders employ refurbished machinery stripped out of the protected cruiser Puerta Espana.  A 20% refit cost to the machinery has been factored into the building cost of the ship overall.

Two units planned for 1913 and a third for 1914.

Jade Class Depot Ship

The Jade class depot ships are intended to support small deployments of mixed forces - sloops, patrol boats, submarines - which might be deployed to a relatively quiet and/or unimportant port.  The mixed bunkerage reflects the differing small craft which might be allocated to her - coal, oil, and diesel.

A run of at least four are anticipated, as the three larger Rubi-class depot ships have ended up being devoted solely to support of Colombian submarine squadrons.

The ship is designed with 1912-generation turbines, there being little practical benefit to the (theoretically, in-character) more expensive new 1916-generation turbines.
