USS Echo (IX-95), an unclassified miscellaneous vessel, was the only ship of the United States Navy to be named for the nymph Echo. A sailing scow, she was used as a supply ship in the South Pacific from 1942 to 1944.
A twin-masted scow (flat-bottomed schooner) of New Zealand registry, Echo was built in New Zealand in 1905 by William Brown, of kauri timber. She was originally topsail rigged. Twin diesel engines were installed in 1920.
She was transferred to the US Navy under reverse Lend-Lease from New Zealand and commissioned on 4 November 1942 with Ensign Meredith C. "Rip" Riddle in command.
Sailing from Auckland on 11 November 1942, Echo delivered cargo at Noumea en route to Efate in the New Hebrides. Based on this island at Port Vila, she served as a supply ship for the United States Army in the New Hebrides and adjoining island groups. On 14 February 1944, just prior to her departure for New Zealand, the Army awarded her crew a commendation. She arrived at Wellington on 12 March 1944, was decommissioned three days later, and returned to the New Zealand Government.
In 1942-44 she was used by US forces in the Pacific, and her story was the basis for the 1960 film with Jack Lemmon, The Wackiest Ship in the Army and the 1965 TV series of the same name. The storyline involved a secret mission with an Australian Coastwatcher, played by Chips Rafferty.
