Thrusters - RCS
Voyager Thrusters
Acronym for Reaction
Control System also referred to as manoeuvring
thrusters. The RCS is a low-power propulsion system for low-velocity
attitude and translational control. Depending on the Starship type,
the system consists of a number of thrusters mostly located at the
edge of the saucer hull.
Although the Star Trek RCS is based on a fusion reaction, its
principle has not changed since the early days of space travel in the
1960's, and similar thrusters were attached e.g. to the hull of the
Apollo spaceship.
Of course there is nothing
necessarily advanced about a reaction control system? Its principle
hasn't changed in essence from the Apollo spacecraft to the 24th
century.
Apollo Thrusters
The original Enterprise
NCC-1701 was lacking visible thrusters, although the ship should have
had them too. Enterprise corrects this error or inaccuracy and gives
the NX-01 four blocks of thrusters at the edges of the saucer where
they are traditionally located on Starfleet vessels at latest since
the Constitution refit. Since the thrusters are just holes, there
isn't any particular retro look to them.
