Armada de México
On 15 August 1978, "Abnaki" began preparations for decommissioning and transfer to the Mexican Navy. She was placed out of commission on 30 September 1978 and was simultaneously transferred to the Mexican Navy. Her name was struck from the Navy list that same day, and she was commissioned in the Mexican Navy as "Yaqui" (A-18), Lt. Guttierez in command.
