CSS ?DAVID? Class Torpedo Boat Papercraft
This paper model is based on CSS David Class Torpedo. CSS David was built by a private venture of T. Stoney at Charleston South Carolina in 1863 and put under the control of the Confederate States Navy.
The cigar-shaped boat carried a 60- or 70-pound explosive charge on the end of aspar projecting forward from her bow.

Operating on dark nights and using anthracite coal which burns without smoke “David” was nearly as hard to see as a true submarine.
