The USS Orvetta (IX–157) was originally built as the steamship Tampa in 1920 by the Oscar Daniels Co. in Tampa, Florida, for the US Shipping Board. She was a civilian vessel before being acquired by the United States Navy on 4 April 1944 through a bareboat charter from the Maritime Commission. Following her acquisition, she was renamed Orvetta and underwent conversion into a barracks ship by the Matson Navigation Company in San Francisco. She was officially commissioned into Navy service on 7 June 1944. Constructed as a mid-sized vessel, the USS Orvetta served primarily as a mobile housing facility during World War II. By 18 June 1944, she was reporting for duty with the Service Force, Pacific. Initially, she operated with Service Squadron 8 headquartered at Pearl Harbor, providing essential living quarters for personnel. As the Pacific campaign advanced, she shifted to Service Squadron 10 to support troops at various forward bases, including in the Philippines, where she was anchored in San Pedro Bay by the end of the war. Following Japan's surrender, Orvetta moved northward, arriving at Okinawa and later reaching Shanghai on 30 September 1945. She remained in Shanghai until 10 May 1946, after which she was taken in tow by USS Serrano to return to the Philippines. She arrived at Subic Bay on 18 May and continued to serve as a barracks ship there until her decommissioning at the end of 1946. The vessel was struck from the Naval Register on 10 June 1947 and was returned to the Maritime Commission on 26 January 1948. Subsequently, she was sold for scrap in early 1949. Throughout her service, USS Orvetta played a vital logistical role in supporting U.S. naval operations across the Pacific theater, exemplifying the importance of auxiliary ships in maintaining wartime operational capacity.
