R-9

 

(Submarine No. 86: displacement 569 (surfaced), 680 (submerged); length 1862; beam 18; draft 146; speed 13.5 knots (surfaced), 10.5 knots (submerged); complement 33; armament 1 3, 4 21 torpedo tubes; class R-1)

 

R-9 (Submarine No. 86) was laid down 6 March 1918 by the Fore River Shipbuilding Co., Quincy, Mass.; launched 24 May 1919; sponsored by Mrs. Irving E. Stowe; and commissioned 30 July 1919, Lt. Comdr. Thomas Shine in command.

 

Following fitting out and shakedown, R-9, designated SS-86 in July 1920, operated along the northeast coast, primarily in the New London-Newport area until 1924. Ordered to the Pacific in March of that year, she arrived at Pearl Harbor, her new homeport, on 4 May. Operations and exercises, from individual to fleet in scope, occupied the next 6 1/2 years and on 12 December 1930 she got underway for return to the Atlantic. Retransiting the Panama Canal in mid-January 1931, she arrived at Philadelphia 9 February and reported for inactivation.

 

Decommissioned 2 May 1931, R-9 remained at Philadelphia, berthed with the Reserve Fleet, until September 1940. Then, placed in reduced commission, she moved up the coast to New London where she completed activation and was placed in full commission 14 March 1941.

 

Within 2 months R-9 was en route to the Caribbean and duty under Commander, Panama Sea Frontier. Arriving at Coco Solo 27 May, she patrolled the approaches to the vital interocean canal with SubRon 3 into October, then returned north to New London for overhaul arriving on the 23d. During December she was attached to the Submarine School but, with the new year, 1942, the submarine proceeded to Casco Bay, Maine, for operational training. From midmonth on, through the U-boat offensive of 1942 and early 1943, she rotated between New London and Bermuda to patrol the shipping lanes which transited the Eastern Sea Frontier and the Bermuda Patrol Areas. Shifted to ASW training programs in the spring of 1943, she operated primarily in the New London area for most of the remainder of World War II. In late March 1945 she moved south again, trained with destroyers, destroyer escorts, and escort carriers off Cuba and southern Florida. Then, in mid-May, she returned to New London.

 

On 20 September R-9 proceeded to Portsmouth, N.H. where she decommissioned 25 September 1945. Struck from the Navy list 11 October 1945, she was scrapped in February 1946.
