This
was a very complex and cumbersome weapons system with many disadvantages
- venting
the
main plasma system of the starship causes an almost total loss of power
while firing, which
means
that the ship must both decloak and drop to sublight speeds while firing.
The guidance system
is
extremely limited by the difficulties inherent in operating any sensor
system through a high energy plasma field, and any degree of manoeuvring
causes a significant drop in eventual yield. Because of these difficulties
the plasma torpedo has therefore not been very successful when used against
mobile targets such as Starships.
Fixed
installations, on the other hand, are a different matter. The plasma torpedo
essentially focuses
the
entire energy output of a starship into one colossal discharge; when used
against a Federation asteroid based outpost a single plasma torpedo collapsed
the shields and caused near total destruction
of
the installation even through several kilometres of solid rock. This level
of destructiveness was not available with any other weapons system of the
time.
Today
the plasma torpedo is still in service with the Romulan Warbird as a heavy
weapon for use
against
fixed installations.
