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.
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.
[12] 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.
The Navy did not release any information about the grounding until press dispatches from San Juan, carrying news of the incident reached the mainland on 23 January.
[18] On 21 March, the Navy announced that Swift would be court-martialed for "through negligence, causing a vessel to run upon a rock" and "neglect of duty in regard to the above".
[23] President Theodore Roosevelt opened the Jamestown Exposition on 25 April, and Connecticut was named as the official host of the vessels that were visiting from other countries.
She was ordered back to the New York Naval Yard, once again on 6 September, for a refit that would make her suitable for use as flagship of the Great White Fleet.
The press in both countries began to call for war, and Roosevelt hoped to use the demonstration of naval might to deter Japanese aggression.
[26] Connecticut left the New York Naval Yard, on 5 December 1907, and arrived the next day in Hampton Roads, where the Great White Fleet would assemble with her as their flagship.
[25] The battleship captains paid their respects to President Theodore Roosevelt on the presidential yacht Mayflower, and all the ships weighed anchor and departed at 1000.
[33] The fleet left Rio on 22 January 1908, still heading south, this time bound for the coaling stop of Punta Arenas, Chile.
[34] Four cruisers from Argentina, San Martin, Buenos Ayres, 9 De Julio, and Pueyrredon, all under the command of Admiral Hipolito Oliva, sailed 300 nmi (350 mi; 560 km) to salute the American ships on their way to Chile.
[36] Peru's president, José Pardo, came aboard Connecticut during this time, as Rear Admiral Evans was quite ill and could not go ashore.
[37] After taking on coal, the ships steamed for Mexico on 29 February, passing in review of Pardo on board the cruiser Almirante Grau before leaving.
[d] After a grand parade through San Francisco, a review of the fleet by Secretary of the Navy Victor H. Metcalf, a gala reception,[40] and a farewell address from Evans (who was retiring due to his illness and his age),[41] the fleet left San Francisco, for Seattle, with Rear Admiral Charles Stillman Sperry as commander.
High seas and winds hampered the ships for part of the voyage to New Zealand, but they arrived on 9 August; festivities, parades, balls, and games were staples of the visits to each city.
[54] Connecticut then led all of these warships around Tail-of-the-Horseshoe Lightship on 22 February to pass in review of President Roosevelt, who was then on the presidential yacht anchored off Old Point Comfort, ending a 46,729 nmi (53,775 mi; 86,542 km) trip.
"[55] Following her return from the world cruise, Connecticut continued to serve as flagship of the Atlantic Fleet, interrupted only by a March 1909 overhaul at the New York Navy Yard.
[58] After several months conducting maneuvers and battle practice off the New England coast, she left for Europe on 2 November to go on a midshipman training cruise.
Connecticut next visited Cherbourg, France, where she welcomed visitors from the town and also hosted commander-in-chief of the French Navy Vice-Amiral Laurent Marin-Darbel, and a delegation of his officers.
[62][63] After taking on stores in Philadelphia, Connecticut sailed for Mexico and arrived on 22 April; she was to patrol the waters near Tampico and Vera Cruz, protecting American citizens and interests during disturbances there and in Haiti.
After the division passed in review before Secretary of the Navy George von Lengerke Meyer on the 25th, Connecticut left for Genoa, Italy, where she remained until 30 November.
[65] She took refugees from Mexico to Galveston and carried officers of the Army and representative from the Red Cross back in the opposite direction.
[66][67] She remained there until 31 July, when she embarked 433 men from the Second Regiment, First Brigade, of the United States Marine Corps for transport to Port-au-Prince, where they were put ashore on 5 August, as part of the US occupation of Haiti.
After two months, Connecticut made another run overseas: following a short period of liberty in Paris, for her crew, she embarked 891 men variously from the 502nd Army Engineers, a medical detachment, and the Red Cross.
[73] On 23 June 1919, after having returned over 4,800 men,[71] Connecticut was reassigned as flagship of the Second Battleship Squadron of the Atlantic Fleet,[6] under the command of Vice Admiral Hilary P.
However, the port engine of Connecticut gave out three days after transiting the canal, requiring New Hampshire to tow the battleship into Guantánamo Bay.
After participating in Naval Academy celebrations on Memorial Day, Connecticut and her squadmates departed on a midshipman cruise which took them to Europe.
After arriving in Portugal, on 21 July, the battleship hosted the civil governor of the province of Lisbon and the commander-in-chief of the Portuguese Navy.
[6] Under the terms of the Washington Naval Treaty, which set tonnage limits for its signatory nations, the Navy designated Connecticut for scrapping.
