Yoyodyne Propulsion Systems

The Yoyodyne Division (also known as Yoyodyne Propulsion Systems or YPS) was a shipbuilding entity that built starships for the United Federation of Planets at various shipyards including 40 Eridani A Starfleet Construction Yards, Copernicus Ship Yards, and San Francisco Fleet Yards in the 24th century.

The Constellation-class starship USS Hathaway was built by Yoyodyne at Luna. (TNG: "Peak Performance")

The Miranda-class starship USS Brattain was built by Yoyodyne at 40 Eridani on stardate 22519.5. (TNG: "Night Terrors")

The Nebula-class starship USS Phoenix was built by Yoyodyne at 40 Eridani on stardate 40250.5. (TNG: "The Wounded")

The Nebula-class starship USS Sutherland was built by Yoyodyne in San Francisco on stardate 44820.5. (TNG: "Redemption II")

The firm had an office on Deep Space 9's Promenade. (Star Trek: Deep Space Nine)

Although not mentioned in dialog, the company's name was listed on a Promenade directory map seen in many episodes of Deep Space Nine.

The existence of this contractor is not mentioned in dialog, but is derived from the text of the starship dedication plaques and display graphics. It is a reference to The Adventures of Buckaroo Banzai Across the Eighth Dimension!, which, in turn, took the name from Thomas Pynchon's novels V. and The Crying of Lot 49 (Star Trek: The Next Generation Companion)
