This is a shuttle papercraft, designed by dacotu. X Bomber is a marionette tokusatsu TV series. It was created by manga master Go Nagai, and produced by Cosmo Productions and Jin Productions. The show aired on Fuji TV from October 4, 1980 to March 28, 1981, with a total of 26 episodes, and was billed in Japan as being filmed in "Sūpāmariorama", a puppeteering process similar to Gerry Anderson's Supermarionation works.
X-Bomber was renamed Star Fleet and dubbed by English speaking actors for broadcast in the UK on ITV. The show was broadcast there on Saturday mornings, first airing on October 30, 1982. Due to its broadcast slot, the advertisements shown before, during and after each episode frequently included children's Public Information Films.
Drawing heavily on diverse influences such as Star Wars, Japanese Anime and Gerry Anderson's various "Supermarionation" series, the show ran for twenty-four half hour episodes. The English version's theme song was composed by Paul Bliss, and was later covered by Queen member Brian May and Van Halen guitarist Eddie Van Halen. This was released under the name "Star Fleet Project".
