Short answers, pulled from the story.
Royal Space Force: The Wings of Honnêamise was released in Japan on the 14th of March 1987 by Toho-Towa, a subsidiary of Toho. It did not receive an English-language release until 1994, when Bandai licensed it to Manga Entertainment.
Royal Space Force was written and directed by Hiroyuki Yamaga. It was co-produced by Hiroaki Inoue and Hiroyuki Sueyoshi, and planned by Toshio Okada and Shigeru Watanabe. It was the debut film of the studio Gainax.
Ryuichi Sakamoto served as music director of Royal Space Force. He was selected for the role in April 1986. Sakamoto was known for his work with Yellow Magic Orchestra and his soundtrack to Merry Christmas, Mr. Lawrence, and the year after Royal Space Force he shared the Academy Award for Best Original Score for The Last Emperor.
Royal Space Force failed to recoup its production costs at the box office. It eventually became profitable through home video sales. Its budget was the largest of any anime film up to that point, surpassing those of Hayao Miyazaki's Castle of Cagliostro and Castle in the Sky.
Royal Space Force was the debut theatrical film of Studio Gainax. Director Hiroyuki Yamaga later said the elements that made the film unsuccessful were the same ones that made possible Gainax's later successes. Hideaki Anno, who worked on the film as special effects artist, stated its difficult reception had a major impact on him personally and professionally.
Investors and sponsors pushed for a title change after finding the completed footage had few merchandise spin-off opportunities. All Nippon Airways wanted the word "wings" in the title, and Bandai preferred the form "Something of Something" following the pattern of the hit Nausicaä of the Valley of the Wind. Director Yamaga objected to the subtitle The Wings of Riquinni and proposed using Honnêamise instead. By the time of release, The Wings of Honnêamise had become the primary title.
