One who discovers a new route through untraversed regions.
Pathfinder (AGS-1), a survey vessel built in 1929 by the Lake Washington Shipyard, Houghton, Wash. for the Coast and Geodetic Survey; acquired by the Navy and commissioned 31 August 1942, Capt. Bascom H. Thomas, USNR, in command.
A sea-going arm of the U.S. Navy's Hydrographic Office, Pathfinder spent the war years paving the way for amphibious invasion.
After shakedown in the Puget Sound area of Washington and a stop at San Francisco, Pathfinder got under way 10 November 1942 and proceeded via Pearl Harbor and Palmyra to the Ellice Islands arriving Funa Futi 26 December.
For nearly two years Pathfinder operated along the dangerous New Guinea-New Britain-Solomon Islands are as allied land-air-sea forces fought to break the Japanese grip on the area. An isolated reef, an uncharted harbor, a lonely stretch of enemy hold coastline-each presented a different problem. At Bougainville, Treasury Island, Green Island, Emirau and Guam, advance Pathfinder parties were sent ashore under the noses of the Japanese to work in close cooperation with Allied amphibious elements in laying out harbor charts or surveying inland channels.
During most of 1943, the ship operated in the Solomons and neighboring groups; the Russells, Admiralties, Loyalties, and New Caledonia. Pathfinder, although nominally a noncombatant, experienced some fifty bombing raids while working close to the front lines. She showed that she could retaliate at Guadalcanal 7 April 1943 when her anti-aircraft gunners bagged two Japanese planes.
At the end of September 1944, after some three months of scientific probing around New Guinea, Pathfinder departed for Espiritu Santo, with written commendations from Admirals Nimitz, Kinkaid, and Halsey. She reached Pearl Harbor 11 October and Alameda, Calif. 21 October.
The proud veteran headed back toward the war zone 18 December 1944. By this time the tide of battle had swept northward to the Philippines.
She reached Guam 4 February to prepare for landings at Casiguran Bay, Luzon 13 March 1945. This first on the eastern coast of Luzon greatly helped to liberate the Philippines. On 28 March two enemy aircraft attacked the ship but she escaped damage.
On 1 May 1945, one month after the initial beachhead was established on Okinawa, Pathfinder churned into Hagushi Anchorage. On 6 May 1945 at "Suicide Slot," Sesoko, a Japanese kamikaze plane crash-dived into the veteran survey ship's after gun platform killing one man, starting fires and setting off ready ammunition. Emergency parties quickly brought the flames under control.
Between her arrival at Okinawa and the final cessation of hostilities 15 August, the ship was at General Quarters 170 times.
Pathfinder anchored at Yokosuka Naval Base, Tokyo Bay, 13 October 1945 and wound up her U.S. Naval career with a series of surveys among the Empire's home islands to assist the Allied occupation.
Pathfinder departed Yokosuka 5 December 1945. Touching at Pearl Harbor 16 December, the ship arrived Seattle 24 December, she decommissioned 31 January 1946, and was transferred to the Commerce Department 22 August. On 1 October 1946 Pathfinder was returned to the Coast and Geodetic Survey. She was struck from the Navy List 13 November 1946.
Pathfinder received two battle stars for World War II service.
