USS Volador (SS-490), a , was the second ship of the United States Navy to be named for the volador.

Construction and commissioning The contract to build her was awarded to Portsmouth Naval Shipyard in Kittery, Maine, and her keel was laid down on 15 June 1945, but work on her construction was discontinued in January 1946. Her unfinished hulk remained on the ways until August 1947, when construction resumed, now including GUPPY II enhancements to the basic Tench-class design. Volador was launched on 21 May 1948, sponsored by Mrs. Harriet Rose Morton (née Nelson), widow of Commander Dudley W. Morton, and commissioned on 1 October 1948, with Lieutenant CommanderRegisters of the Commissioned Officers of the United States Navy and Marine Corps 1949 Howard A. Thompson in command.

Operational history

West Coast

Volador completed her builder's trials on 20 January 1949, left Portsmouth three days later, and stopped at Newport, Rhode Island, and New London, Connecticut, before sailing for the Gulf of Mexico on 5 February. Volador arrived at New Orleans, Louisiana, on 11 February and proceeded to the West Coast, via Galveston, Texas, and the Panama Canal, and arrived at San Diego, California, on 11 March. The submarine conducted local operations along the California coast between San Diego, California, and San Francisco, California, until she departed San Diego on 13 October, bound for Hawaii. She arrived at Pearl Harbor on 7 November but returned to San Diego on 18 November and spent the remainder of 1949 as well as most of the following year on the West Coast, conducting various training exercises. During that period, she also visited Portland, Oregon, Vancouver, Washington, and Pearl Harbor. In June 1950, Volador embarked reserves at Treasure Island, San Francisco, and proceeded on a two-week reserve cruise to Hawaii. En route, the Korean War broke out, and the submarine spent two months training in Hawaiian waters before returning to San Diego for operations on the West Coast that lasted into the summer of 1951.

Korean War

The submarine departed San Diego, California, on 21 July, bound, via Pearl Harbor, for Japan and arrived at Yokosuka on 15 August 1951. On 18 August, Volador got underway from Yokosuka for a period of special operations. Her orders directed the submarine to conduct an undetected reconnaissance patrol in the area of Hokkaidō, Japan, for a four-week period, in order to keep Commander, Naval Forces Far East, informed of any Soviet or People's Republic of China's seaborne and airborne activity in that area. Throughout her patrol, the submarine identified and photographed numerous radar contacts and made rendezvous with submarines and to exchange patrol reports and other valuable information. On 16 September, Volador held ceremonies commemorating her 1000th dive. After a 24-hour engineering run in Tsugaru Strait, she ended her patrol and arrived in Yokosuka on 22 September. From 11 to 15 November, Volador conducted ASW operations with destroyers , , and in the Atami area. From 16 November to 9 December, Volador participated in hunter/killer operations en route to Okinawa from Japan in company with Task Group (TG) 96.7. The submarine visited Buckner Bay, Okinawa, before heading home via Pearl Harbor.

Volador returned to San Diego, California, in January 1952 and conducted local operations until early summer. She then spent three months in the Juan de Fuca Strait and the Puget Sound area before entering the Mare Island Naval Shipyard in October. During the five-month overhaul which followed, a new battery and an Askania automatic depth control system were installed. Upon her return to San Diego, Volador provided services to ASW surface units, aircraft, and the Fleet Sonar School and participated in type training, Exercise "Pacphibex", and hunter/killer exercises. She departed San Diego on 7 August 1953 and arrived at Pearl Harbor on 15 August, received briefings by members of the Commander in Chief, Pacific Fleet, and the Commander, Submarines, Pacific staffs on 17 and 18 August and tested experimental sonar equipment at sea on 20 August.

Special operations

On 22 August 1953, Volador began a period of special operations, departing Pearl Harbor for an Alaskan training cruise which kept her in northern waters until October 1953. Her patrol station was northeast of the St. Lawrence Bay, and, on 1 September, she made rendezvous with submarine off the southwest cape, St. Lawrence Island; the following day, she snorkeled to an area off Brook Bank, then proceeded to the Bering Strait area. Volador conducted a shipping reconnaissance patrol until the night of 27 September 1953 when she made rendezvous with and was relieved by submarine . Volador arrived at Pearl Harbor on 7 October 1953. During her second patrol, she contacted a total of 63 ships and identified and photographed the majority of them.

Western Pacific

Returning to San Diego, California, Volador rendered services and conducted type training there until May 1954, when she entered the Mare Island Naval Shipyard for overhaul. The yard work was completed in October 1954 and Volador returned to San Diego for local operations. Departing San Diego on 3 January 1955 for her second tour of duty in the Western Pacific (WestPac), Volador proceeded to Yokosuka, Japan, via Pearl Harbor. Upon arrival at Yokosuka on 26 January 1955, she conducted type training and furnished ASW services to a destroyer division and elements of the Japan Maritime Self-Defense Force until 1 March 1955. She then completed two weeks of routine upkeep on 13 March, prior to departure for another period of special operations on 14 March.

Volador transited Tsugaru Strait and, on 19 March commenced a submerged patrol on the lane between Vladivostok and La Perouse Strait which lasted until 8 April. She then commenced a transit of Tsugaru Strait and set a course back to Yokosuka where she moored on 11 April 1955. After the completion of this patrol, Volador was commended for excellent photography, correct identification of contacts, and accurate reporting of identifying characteristics regarding the 33 ships contacted.

West Coast

Visiting Subic Bay, Hong Kong, and Pearl Harbor while en route, Volador returned to San Diego, California, on 1 July. The submarine operated along the West Coast for the next two years. In August 1957, Volador commenced another Far East deployment. She arrived at Pearl Harbor on 3 August and departed three days later for a 30-day patrol off Petropavlovsk, Kamchatka. Her mission was to gather intelligence information. Due to motor casualties nine days after arrival on station, she departed the Petropavlovsk area on 25 August and arrived at Yokosuka five days later. During this patrol Volador contacted 13 merchant ships and eight warships.

On 8 November 1957, the submarine arrived at Subic Bay for a scheduled upkeep and departed on 17 November for Yokosuka. Volador arrived at Yokosuka on 26 November; and, from 11 December through 4 January 1958, she conducted a special reconnaissance patrol in the Sea of Okhotsk. During this 17-day undetected special patrol, she completed her photographic mission in spite of severe ice and blizzard conditions. Returning to Japan, Volador departed Yokosuka on 9 January for Pearl Harbor. She arrived at Hawaii on 19 January and departed two days later for San Diego, arriving on 28 January 1958.

Volador remained at San Diego until 3 October, when she departed for Vancouver, Washington. Twenty guests of the Vancouver Navy League were embarked at Longview, Washington, for a ship's visit and disembarked upon arrival at Vancouver. Volador was welcomed by a gathering of about 500 citizens, plus the local high school band, and was presented a plaque in a simple ceremony on board. She departed Vancouver on 5 October and visited Seattle, Washington, and Port Angeles, Washington, through the month of October. Volador visited Victoria, British Columbia, from 31 October through 3 November. Canadian frigate HMCS Antigonish was the host ship, and wardroom officers were entertained on board and in the homes of the host's officers.

The submarine patrolled the areas of Esquimalt, Washington, Port Angeles, Washington, Tacoma, Washington, and Seattle, Washington until 22 November when she began her return trip to San Diego, California, arriving on 26 November. Volador operated in the San Diego-San Francisco area until 5 May 1959 when she entered the San Francisco Naval Shipyard at Hunters Point for overhaul.

Completing overhaul in October 1959, the submarine returned to San Diego, California, for local operations until leaving for WestPac in late December. While thus deployed, Volador participated in many operations including amphibious Exercise "Blue Star" and SEATO Exercise "Sea Lion." Upon returning to San Diego, she participated in various local operations during the next 20 months.

In August 1960, "Volador" was assigned as a target submarine for the USS Kingfor the testing the new ASROC MK-44 torpedo system. While at periscope depth and being tracked by USS King's SQS-23B sonar, King fired an ASROC. The MK-44 torpedo separated from the rocket motor hit the Volador's sail after entering the water, leaving a hole in its sail.

Conversion

Volador spent the early months of 1962 in local operations in the San Diego area until she conducted a reserve cruise from 4 to 11 April. Upon her return, she was placed in commission, in reserve, while undergoing FRAM Mk 1 conversion to a GUPPY III configuration at the San Francisco Naval Shipyard. The submarine was saved from possible total destruction due to a spectacular pier fire at the shipyard on 9 and 10 November 1962 by the duty section led by the duty officer and the executive officer. In September 1962, Volador was returned to active service. The conversion was completed in February 1963. A hull section was installed in addition to a large amount of new electronic, fire control, and sonar equipment, making Volador one of the most modern diesel-electric submarines in the Fleet. After trials in Puget Sound, she returned to San Diego in April 1963 to take part in local operations.

Vietnam era

The submarine departed San Diego in September 1963 for another WestPac deployment. Near the conclusion of her tour, Volador conducted a special assignment which resulted in her receiving a commendation from the Commander, Submarine Force, United States Pacific Fleet, for "a mission of great value to the government of the United States." After returning to San Diego, she was assigned to local and Pacific coast operations.

In late 1964, Volador again distinguished herself by sending the submarine hulk ex- to the bottom after firing one homing torpedo in a weapons system evaluation test, making her the only submarine in the Navy to claim two peace-time "kills". Commander, Submarine Force, United States Pacific Fleet, awarded the "E" for overall performance "and for being adjudged the outstanding submarine in Submarine Squadron 5 in fleet intra-type competition for fiscal year 1965."
