USS Connecticut (BB-18) [SEP] Construction
As "Connecticut" was only 55% complete when she was launched, missing most of her upper works, protection, machinery and armament, it was two years before "Connecticut" was commissioned on 29 September 1906. Captain William Swift was the first captain of the new battleship. "Connecticut" sailed out of New York for the first time on 15 December 1906, becoming the first ship in the US Navy to ever go to sea without a sea trial. She first journeyed south to the Virginia Capes, where she conducted a variety of training exercises; this was followed by a shakedown cruise and battle practice off Cuba and Puerto Rico.
