Constellation was the last sail-powered-only warship built by the US Navy. Built in 1854 and launched in 1855, she served until decommissioned in 1955. By then she was misidentified as her namesake, the frigate Constellation, and was sent to Baltimore Maryland where the city tried to restore her as such. While she is not, and never has been the frigate, this claim is probably the only reason the ship still exists today, restored as the sloop-of-war she always has been.
The model attempts to depict her as she appeared in a portrait of her by Tomaso deSimone at anchor in Naples in 1856.
She is radio-controlled with 4 channels: 1 winch handles the fore mast sails, 1 winch handle the main & mizzen mast sails, a "sail-arm servo" handles all the fore-and-aft sails (jibs, spanker, etc), and the final channel is for the rudder.
