Oxford-class research ship

The Oxford class of technical research ships were a class of three World War II Liberty ships converted in the early 1960s to provide a seaborne platform for global eavesdropping on behalf of the National Security Agency. The ships of this class were similar to the Belmont-class ships of the same era with the difference being that they were adapted from Victory ships.
