USS Bluebird (AMS/MSC-121) was a Bluebird-class minesweeper acquired by the United States Navy for clearing minefields in coastal waterways.

The third Bluebird to be so named by the Navy, AMS-121 was laid down on 5 February 1952, at Vallejo, California, by the Mare Island Naval Shipyard; launched on 11 May 1953; sponsored by Mrs. G. C. Demmon; and commissioned on 24 July 1953.

[2] The minesweeper operated out of San Diego, California, performing the usual tasks such as type training and fleet exercises.

She transited the Panama Canal on 19 May, and after a visit to Guantánamo Bay, Cuba, arrived in her new home port on 27 May.

[2] In January 1961, Bluebird began making regular periodic deployments to the West Indies serving under the auspices of the Commander, Fleet Training Group, Guantanamo Bay.

It was on one of those deployments that, during the summer of 1965, she earned the Armed Forces Expeditionary Medal for her role in the American intervention to restore order in the volatile Dominican Republic.
