Mira (AK-84) was never commissioned and thus never bore the USS designation.[1]. The ship was transferred to become the U.S. Army Corps of Engineers Port Repair ship Robert M. Emery the day after acquisition by Navy.


The ship was laid down under Maritime Commission contract by Penn-Jersey Shipbuilding Corporation, Camden, New Jersey, 22 May 1943 as MV William Nott, a Maritime Commission type N3-M-A1 cargo vessel. The ship was launched 31 October 1943; sponsored by Mrs. Clementine C. O’Brien; acquired by the U.S. Navy 6 November 1943 for service as Mira (AK-84). However, she was never commissioned and was transferred to the Army 7 November 1943. Her name was struck from the Navy list 16 November 1943.

Army career

Mira was renamed Robert M. Emery in 1944 for First Lieutenant Robert M. Emery of the U.S. Army Corps of Engineers serving with the st Infantry Division and killed in action on 8 November 1942 in Algeria. Lieutenant Emery was presented the Distinguished Service Cross posthumously for his action on that date.[2]

Robert M. Emery was among the first four of the N3-M-A1 types converted for use as a U.S. Army Corps of Engineers port repair ship.[3] The conversion work was done by Bethlehem Steel Co., Inc., Brooklyn, New York, in mid 1944.

Robert M. Emery joined her three sister ships and the converted Great Lakes steamer Junior N. Van Noy as one of the five ships leaving in late summer of 1944 for operations in Europe.[3] She then began operations at ports in the United Kingdom, North Africa, and France. She was the only member of that group to operate in the Pacific Ocean, going there in July 1945 to operate in the Hawaiian Islands between September and November. Subsequently, she returned to the United States West Coast for transfer to the Maritime Commission. Mira was returned to the Maritime Commission. She eventually was sold for scrapping in 1966.
