Enzmann starships are concepts for a crewed interstellar spacecraft by Dr. Robert Enzmann. In the original design proposed in 1964, a three million ton ball of frozen deuterium would fuel nuclear fusion rocket engines contained in a cylindrical section behind that ball with the crew quarters. The craft would be about 2,000 feet (600 m) long overall. Later designs, such as the Echolance, are smaller and involve ramjet style engines.
