PNS DuQuesne was the lead ship of the eponymous class of superdreadnoughts built and used by the People's Republic of Haven.
In 1879 PD, she was commissioned and put on space trials prematurely when Anton DuQuesne, the political heir to the DuQuesne Plan, was killed in an aircar accident. The ship's rapid construction and launch made it go through many working trials before it was permanently attached to the Capital Fleet for training purposes. (JIR2)
