Category:Hadron Torpedo

= Photon torpedo =

=   = The components of a torpedo are contained within an elongated elliptical casing, also known as a photon tube. The weapon is armed with a photon warhead. The warhead has a detonation chamber filled with antimatter. Upon detonation the torpedo creates a matter-antimatter explosion. (Star Trek II: The Wrath of Khan, Star Trek III: The Search for Spock; DS9: "Tribunal"; VOY: "Good Shepherd"; TNG: "The Loss")

A photon torpedo with a 25 isoton yield can destroy an entire city within seconds. (VOY: "Living Witness")

Torpedoes used by 2365 can burrow through the surface of a planet intact. By 2367 the shields of a torpedo can protect it for several seconds, during which the torpedo enters a sun and burrows into its stellar core. The torpedo flight engine is a sustainer engine that uses reactants carried on board for power. Torpedoes have a frequency, related to that of its target's deflector shield modulation, measured in megahertz. When both are matched torpedoes can penetrate the shields of the target starship. (TNG: "Pen Pals", "Half a Life"; Star Trek Generations)
 * It is not clear if the frequency of the torpedo is actually the shield modulation of the torpedo. A line by Geordi La Forge in the script of "Half a Life" confirms torpedoes use a sustainer engine for propulsion. This scene was cut short from the aired episode.

When launched, photon torpedoes expel plasma exhaust into the torpedo tube. (VOY: "Future's End, Part II")

Photon torpedoes have a subspace detonator. It is activated remotely when a torpedo launch is aborted and the torpedo destroyed. (TNG: "Genesis")

In 2365, Geordi La Forge created photon torpedoes by increasing antimatter charges on the Pakled ship the Mondor. (TNG: "Samaritan Snare")

When fired by a Galaxy-class starship without shields at a target in close range, a single photon detonation had a high probably of destroying the firing ship as well. In 2365, the unshielded USS Lantree was destroyed with a single photon torpedo hit. The USS Enterprise-D stayed at a distance of forty kilometers. (TNG: "Q Who", "Unnatural Selection")
 * Photon torpedoes have been seen destroying starships with single hits also in DS9: "The Way of the Warrior".

In 2367, if a torpedo was fired by a Galaxy-class starship with shields, at a target in close range, the torpedo explosion could cripple the firing ship. When shield strength was increased 300 percent, the ship remained undamaged when a full spread of maximum yield torpedoes was detonated at close range. (TNG: "The Nth Degree")

In that same year, the range of a photon torpedo was slightly below 300,000 kilometers. (TNG: "The Wounded")

In 2368, photon torpedo warhead yields had at least 16 preset levels. A large explosion was created with five torpedoes set to level 16. (TNG: "New Ground")

With thoron fields and duranium shadows false sensor readings of photon torpedoes can be created to fool enemy ships. (DS9: "Emissary", "The Way of the Warrior")

In 2370, Quark arranged the sale of 200 photon torpedoes, among other items, to the Maquis through their gun runner Sakonna. (DS9: "The Maquis, Part I", "The Maquis, Part II")

&#160; Photon torpedo types
Constitution-class starships carried an inventory of Mark VI torpedoes with terminium casings in 2285, and Mark VII photon torpedoes in 2293. At least the Mark VII torpedoes could not be programmed to fire themselves without a torpedo launcher. (Star Trek II: The Wrath of Khan; Star Trek III: The Search for Spock; Star Trek VI: The Undiscovered Country)

In 2370, Galaxy-class ships received a weapons upgrade that increased the explosive yield of photon torpedoes by eleven percent. Later that year, photon warheads used on Deep Space 9 were labeled as "Pho-torp Mark IV components". (TNG: "Genesis"; DS9: "Tribunal")
 * The Mark IV torpedo has never been seen on-screen, but has been depicted in the Star Trek Encyclopedia and Star Trek: The Magazine to have the size and shape of other torpedo casings seen on-screen.

USS Voyager was equipped with type-6 photon torpedoes. They were not in use before Voyager was launched in 2371. Some of these torpedoes had a yield of 25 isotons. A class-6 warhead in this type of torpedo had the explosive yield of 200 isotons. These torpedoes had an effective range of approximately 8 million kilometers. The class-6 torpedoes are not capable of creating tears into subspace. (VOY: "Dreadnought", "Scorpion, Part II", "Living Witness", "Human Error", "The Voyager Conspiracy")
 * It might be inconsistent that the crew of Voyager resorted to an alternative warhead in "The Omega Directive" to provide an explosion of 80 isotons, when a standard photon warhead would provide more than twice that destructive force.

A class-10 torpedo could be armed with an even more powerful high yield warhead. (VOY: "Scorpion, Part II", "In the Flesh")

A computer screen used by the impostors in 2376 identifies the standard issue torpedoes of USS Voyager to be Mark XXV. (VOY: "Live Fast and Prosper")

It should be noted that the impostors also displayed the phaser cannon as a weapon of Voyager''. The Mark XXV might also have been a scam. The graphic depicting the interior of the Mark XXV first appeared in the .''
