USS Summit County (LST-1146) was an LST-542-class tank landing ship in the United States Navy. Unlike many of her class, which received only numbers and were disposed of after World War II, she survived long enough to be named. On 1 July 1955, all LSTs still in commission were named for US counties or parishes; LST-1146 was given the name Summit County, after counties in Colorado, Ohio and Utah. She was decommissioned in 1969 and placed in reserve. She was sold to Ecuador and renamed BAE Hualcopo (T-55). Although she suffered a major fire in July 1998, she was still in service with the Ecuadorian Navy as of 2007 under her current pennant number of TR-61.
