USS Allioth (AK-109/IX-204/AVS-4) was a Crater-class cargo ship commissioned by the US Navy for service in World War II, named after Alioth, a star in constellation Ursa Major.

SS James Rowan was laid down under a Maritime Commission (MARCOM) contract, MCE hull 1730, on 30 July 1943, by the Permanente Metals Corporation, Yard No.

Ten crewmen were slightly wounded, and the ship suffered minor structural damage from shrapnel.

After taking on more cargo there, she resumed her westward voyage, dropped anchor at Ulithi on 8 April, and began supplying various units with airplane parts.

In early June, the ship sailed to Seeadler Harbor, Manus Island, to load more spare parts.

[3] Allioth moved to Okinawa in mid-September 1945, and remained there into the next year, supporting various airplane squadrons operating in the Ryukyu Islands.
