06/30/2014. Remarks by Walter van Tilborg and Johan Visschedijk: "The original Rocket 185 was a design of Rufus Summerfield 'Pop' Johnson and when Johnson joined the Regent Aircraft Company, a much modified version was developed. The Rocket 260 had a more powerful 260 hp Lycoming GSO-435 engine, a much modified tail group, a longer fuselage with a larger and roomier four-seat cabin and an all-metal construction. Registered N77637 the prototype was first flown on April 22, 1951.

A projected five-seat version, designated Rocket 400, had a similar airframe as the Regent 260, but was to be powered by a 400 hp Lycoming GSO-480-D engine; it was never built. Eventually the development of the Regent Rocket was halted, although Johnson later planned a production model as the Johnson 260 with a 260 hp Continental IO-470 engine. Again this version was not built."
