Torpedoes
There are two types of photon torpedoes, the first type contains six slugs
of deuterium which are fired at corresponding slugs of antideuterium
at detonation, the explosive energies then created are briefly held by
a containment field, and then released. Although the torpedo could
coast indefinitely after launch, it has a maximum range of 750,000 km
due to stability limits of the anti-matter containment unit.
The second type of
torpedo is the one which Starfleet currently use. This torpedo has a
maximum range of 3,500,000 km. In this torpedo thousands of tiny
packets of matter and antimatter are held in suspension by powerful
magnetic fields. This device also has a variable yield.
Until launch these
packets are held in separate regions of the torpedo, as a safety
precaution. Upon launch the packets are mixed, although they don't
come into contact. At detonation the fields holding the
matter/antimatter apart collapse, and the torpedo explodes. The
maximum payload in a standard torpedo is 1.5 kg of antimatter and 1.5
kg of deuterium. This payload would cause an explosion of 18.5 isotons.
The standard torpedo casing used by Starfleet is 2.1 x 0.76 x 0.45 m
and weighs 247.5 kg (before loading)
Torpedo Propulsion
The torpedo can
sustain warp velocities due to it's internal multi-mode warp-field
sustainer system. This system is not a true warp-engine due it's small
size. It is only intended as a matter/antimatter fuel cell, which uses
the field sustainer coils to 'grab' and hold a 'hand-off' field from
the torpedo launcher in order to maintain the torpedo's velocity if
launched at warp. Due to the small size of the matter/antimatter cell
the torpedo can only travel 0.75c faster than the launch velocity. The
torpedo steers by differentially constricting the sustainer exhaust
grills.
Quantum Torpedo
The quantum torpedo
is the first Starfleet follow-on weapon to replace the standard
photon torpedo first developed in 2268. During upgrade testing of the
Mark-IX warhead, it was determined that the theoretical maximum
explosive yield of 25 isotons had finally been reached for a
matter-antimatter reaction. Existing and future threat force conflicts
drove the development of a new defensive standoff weapon that could be
deployed on specially equipped Starships, star bases, and
planetary-surface fortifications.
Advances in rapid
energy extraction from the space-time domain known as the zero-point
vacuum eventually led the Starfleet R&D facility on Groombridge 273-2A
to test a prototype continuum-twist device with a calculated potential
of 52.3 isotons.
The quantum torpedo
consists of a pressure-moulded shell of densified tritanium and
duranium foam, trapzoidal in cross section and tapered at the forward
end for atmospheric applications. A 7 millimeter layer of
plasma-bonded terminium ceramic forms an ablative armour skin for the
foam hull, over which is bonded a 0.12 mil limiter coating of
silicon-copper-yttrium rigid polymer as an antiradiation coating.
The Micro Quantum
Torpedo was introduced to help arm the relatively small and undefended
Starfleet Runabouts. Although Runabouts were equipped with Phaser
arrays, a more powerful weapon was required to help defend the
Runabouts against larger, more powerful opponents such as the Dominion
fighters they were frequently encountering. Measuring just 13 cm in
length, the Micro Quantum Torpedo is the most powerful weapon of it's
size. When fired from a Runabout, the torpedo incorporates a mini
guidance system which will home in on the nearest enemy target, but
this guidance system does not kick in until 3.7 seconds after it is
launched in order to let it clear the vicinity of the Runabout. As
with all torpedoes, the Micro Quantum Torpedo can be fired while the
ship is at Warp.
Storage and Other uses
Space burial such as that of Spock,
Starfleet uses torpedoes to bury fallen comrades based on the
tradition of the Navy, such as in Star Trek II - The Wrath of Khan. An
example of the 'Spock' torpedo for space burial is shown here
Ship storage is in the main armory in the stacked locked bays
