USS Cusabo (ATF-155) was an Achomawi class fleet ocean tug built for the United States Navy during World War II.

Picking up tows there and at Portsmouth, New Hampshire, she departed Newport on 4 July for San Diego, California arriving 27 August.

Cusabo remained in the Far East on towing and salvage duty at Guam, Saipan, Iwo Jima, and Eniwetok until 10 March 1946 when she proceeded to Bremerton, Washington for pre-inactivation availability and overhaul, arriving 11 May.

In 1962, Cusabo was removed from the Columbia River Reserve Fleet and loaned to the government of Ecuador, where she was returned to service as BAE Los Rios (RA-01).

Later renamed BAE Cayambe, the ship was permanently transferred (cash sale) to Ecuador under the Security Assistance Program on 1 August 1978.
