The oscillation overthruster was a device in Soong-type androids. This device was located in the primary system module (torso) of the androids.
In 2365, when Commander William T. Riker was reviewing the technical specifications for Lieutenant Commander Data, this device was listed as one of the components in the primary system module. (TNG: "The Measure Of A Man")
This is one of the numerous references in
Trek to The Adventures of Buckaroo Banzai Across the 8th Dimension. An actual Oscillation overthruster prop made an appearance on a number of occasions in several
Star Trek series.
From the Star Trek Encyclopedia (4th ed., vol. 2, p. 115), "
A small hand prop from the 1982 motion picture The Adventures of Buckaroo Banzai Across the 8th Dimension
, written by Earl Mac Rauch
and directed by W.D. Richter
. In the film, the overthruster was invented by Dr. Buckaroo Banzai
and was the key to interdimensional travel. A replica of this prop was supplied to Star Trek
by modelmaker Greg Jein
for use in Star Trek V: The Final Frontier
, althought it was not actually seen in the film. It was used several times in various Star Trek
episodes, but it was never called an overthruster. The first was as an isolinear chip
reader used by Wesley Crusher
). The overthruster was repainted and used again in "Pen Pals
" (TNG) as a spectral analyser device in the planetary geosciences lab. In "The Best of Both Worlds" (TNG), it was once again repainted and used as a Borg
surgical instrument. Dr. Bashir
used it as a handheld sensor
in "A Man Alone
). It was a Cardassian
tool on at least one occassion. Additional replicas were later made, which appeared among the equipment installed in Zefram Cochrane
's spaceship Phoenix
during his historic warp flight in Star Trek: First Contact
." Note: The film was released in 1984, not 1982.
