The design of the Imperial Lambda-class shuttle in Star Wars is attributed to Joe Johnston and Ralph McQuarrie, with James Clyne also contributing early concepts for a larger, four-winged version. Johnston and McQuarrie's work laid the foundation for the iconic design, while Clyne's concept explored variations on the classic design.

Ralph Angus McQuarrie (/məˈkwɒriː/; June 13, 1929 – March 3, 2012) was an American conceptual designer who worked in film and television. His career included work on the original Star Wars trilogy, the original Battlestar Galactica television series, the film E.T. the Extra-Terrestrial, and the film Cocoon, for which he won an Academy Award.
