USS Rainbow

USS Rainbow (AS-7) was the only ship in the United States Navy by that name. The ship was originally converted to a distilling ship in 1898, and then converted again in 1917 to a submarine tender.

Rainbow was built in 1890 as the merchant ship Norse King by James Laing at Sunderland, England. She was purchased by the U.S. Navy on 29 June 1898, placed in reduced commission on 18 July, and transferred to the New York Navy Yard for fitting out for use as a distilling and station ship in the Philippines.

Asiatic Fleet, 1901–1908
Rainbow was commissioned in full on 2 December 1901, Comdr. S. A. Stanton in command, and was assigned to the Asiatic Fleet. En route to the Philippines, she sailed via Gibraltar for the Suez Canal, calling at Palermo, Sicily; Port Said, Egypt; Colombo, Ceylon; and Singapore before arriving at Cavite on 3 April 1902.

Rainbow, as flagship of the Philippine Squadron, remained in the Philippines, with only periodic runs to Hong Kong for repairs, until 1906. Her range was then expanded from an annual circuit among Philippine ports to include visits to various Japanese ports, and in November 1907, a call at Vladivostok with Secretary of War Taft embarked.

Pacific Fleet, 1908–1911
Becoming flagship of the 3rd Squadron, Pacific Fleet, in 1908, Rainbow cruised among the Philippine and Japanese islands and off the coast of China, and, on at least one occasion, December 1908-January 1909, conducted hydrologic surveys. Then, designated tender to the First Torpedo Flotilla, she alternated between the China coast and the Philippines until pressed into service as a transport in 1911.

Asiatic Fleet, 1911–1914
Rainbow departed Cavite on 26 October 1911, en route with an expeditionary force of Marines landed at Wusong (31 October-1 November) to help protect American nationals from imminent dangers of the revolutionary turmoil in China. She became the temporary flagship of the Commander-in-Chief, Asiatic Fleet, 1 November 1911, cruising the China coast to observe conditions which might affect the safety of Americans at Shanghai, Wusong, Nanjing, Amoy, Shantou, Qingdao, and Taku.

USS Saratoga (ACR-2) relieved Rainbow as Asiatic Fleet flagship on 10 April 1912. Rainbow then proceeded to Huangpu where she became the flagship of the China Squadron on 13 April. She supported Marine expeditionary forces on the China coast until 30 August 1912, when she sailed from Yantai for repairs at Olongapo, Philippine Islands.

Rainbow shifted from Olongapo to Cavite on 8 October 1912 and served there as temporary flagship for the Commander-in-Chief, Asiatic Fleet (30 October-7 November). She departed Cavite on 7 November 1912, bound by way of Wusong, Shanghai, and the Yangtze River to Nanjing, China. She arrived at Nanjing on 20 November and sailed 10 days later to cruise with the American ambassador to the ports of Shanghai, Hong Kong, Shantou, Amoy, and Wusong. She departed Wusong on 28 December 1912, investigating the landing facilities at Lingayen Gulf in the Philippines before being repaired at Olongapo in January 1913.

Rainbow shifted from Olongapo to Cavite on 26 January 1913 and remained in the Philippines until 28 March when she again set course for the coast of China. She transferred stores and men to USS Piscataqua (AT-49) at Wusong, then served as a station ship at Shanghai until 4 November 1913. After calling at Olongapo, she proceeded to Manila, embarked the Commander-in-Chief for transport to Shanghai, and served there as flagship from 21 December 1913 to 19 January 1914.

Rainbow resumed station ship duty at Cavite on 22 January 1914. She again became temporary flagship of the Commander-in-Chief at Cavite on 1 March 1914, but terminated this duty on 23 March 1914 when she shifted to Olongapo for overhaul, completed on 8 July 1914. She departed Manila Bay on 16 July 1914, taking refuge from a storm in Lingayen Gulf the 18th, before proceeding to survey the French Frigate Shoals, Hawaii (7-10 August 1914). She arrived at Honolulu 12 August, basing there for further survey work off the French Frigate Shoals until 14 November 1914. She then set course for San Francisco, arriving 24 November 1914 and shifting to the Mare Island Navy Yard the following day to prepare for inactivation. She decommissioned in the Mare Island Navy Yard on 24 December 1914.

Conversion to submarine tender, 1916–1918

Upon arrival at Cavite, Philippine Islands, Rainbow became the flagship of Submarine Flotilla 3 (later designated Submarine Division), Asiatic Fleet.
