USS Luiseno

USS Luiseno (ATF-156) was an Abnaki-class fleet ocean tug built for the United States Navy during World War II.

During the summer of 1946 the fleet tug made a cruise to Bremerhaven, Germany to tow a 350-ton crane to Cristóbal in the Canal Zone, arriving there 20 September.

From 1946 Luiseno performed miscellaneous duties including target towing, salvage operations, and other vital services, along the east coast, in the Caribbean and from her home port, Newport, Rhode Island.

Decommissioned and struck from the Naval Vessel Register on 1 July 1975, Luiseno was subsequently transferred to Argentina under terms of the Security Assistance Program and renamed ARA Francisco de Gurruchaga (A-3).

From a total of 770 crewmembers rescued, 365 were saved by Gurruchaga, whose powerful searchlights and low freeboard proved particularly useful in recovering survivors from their liferafts.
