USS Connecticut (BB-18), the fourth United States Navy ship to be named after the state of Connecticut, was the lead ship of her class of six pre-dreadnought battleships. Her keel was laid on 10 March 1903; launched on 29 September 1904, Connecticut was commissioned on 29 September 1906, as the most advanced ship in the US Navy.

Connecticut served as the flagship for the Jamestown Exposition in mid-1907, which commemorated the 300th anniversary of the founding of the Jamestown colony. She later sailed with the Great White Fleet on a circumnavigation of the Earth to showcase the US Navy's growing fleet of blue-water-capable ships. After completing her service with the Great White Fleet, Connecticut participated in several flag-waving exercises intended to protect American citizens abroad until she was pressed into service as a troop transport at the end of World War I to expedite the return of American Expeditionary Forces from France.

For the remainder of her career, Connecticut sailed to various places in both the Atlantic and Pacific while training newer recruits to the Navy. However, the provisions of the 1922 Washington Naval Treaty stipulated that many of the older battleships, Connecticut among them, would have to be disposed of, so she was decommissioned on 1 March 1923, and sold for scrap on 1 November 1923.

Design

Connecticut was long overall and had a beam of and a draft of . She displaced as designed and up to at full load. The ship was powered by two-shaft triple-expansion steam engines rated at , with steam provided by twelve coal-fired Babcock & Wilcox boilers ducted into three funnels. The propulsion system generated a top speed of . As built, she was fitted with heavy military masts, but these were quickly replaced by lattice masts in 1909. She had a crew of 827 officers and men, increased to 881 and later to 896.

The ship was armed with a main battery of four 12 inch /45 Mark 5 guns in two twin gun turrets on the centerline, one forward and aft. The secondary battery consisted of eight /45 guns and twelve /45 guns. The 8-inch guns were mounted in four twin turrets amidships and the 7-inch guns were placed in casemates in the hull. For close-range defense against torpedo boats, she carried twenty /50 guns mounted in casemates along the side of the hull and twelve 3-pounder guns. She also carried four 1-pounder guns. As was standard for capital ships of the period, Connecticut carried four 21 inch (533 mm) torpedo tubes, submerged in her hull on the broadside.

Connecticuts main armored belt was thick over the magazines and the propulsion machinery spaces and elsewhere. The main battery gun turrets had thick faces, and the supporting barbettes had of armor plating. The secondary turrets had of frontal armor. The conning tower had thick sides.

Service history

Construction

Connecticut was ordered on 1 July 1902. On 15 October 1902, she was awarded to the New York Naval Shipyard. She was laid down on 10 March 1903, and launched on 29 September 1904. She was sponsored by Miss Alice B. Welles, granddaughter of Gideon Welles, Secretary of the Navy during the American Civil War. A crowd of over 30,000 people attended the launch, as did many of the Navy's ships. The battleships , , , , , , , and were at the ceremony, along with the protected cruisers and and the auxiliary cruiser .

Three attempts to sabotage the ship were discovered in 1904. On 31 March, rivets on the keel plates were found bored through. On 14 September, a bolt was found driven into the launching way, where it protruded some . Shortly after Connecticut was launched on 29 September, a diameter hole was discovered drilled through a steel keel plate. The ship's watertight compartments and pumps prevented her from sinking, and all damage was repaired. The incidents prompted the Navy to post armed guards at the shipyard, and an overnight watch was kept by a Navy tug manned by Marines who had orders to shoot to kill any unauthorized person attempting to approach the ship.

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. During the cruise, she participated in a search for the missing steamer Ponce.
