Phasers are common and versatile phased array pulsed energy projectile weapons, first seen in the original Star Trek series and later in almost all subsequent films and television spin-offs.
Phasers can be set to overload, whereby they build up a force-chamber explosion by continuously generating energy without releasing it; the resulting blast can destroy most natural objects within a 50-meter (160 ft) radius.
The Star Trek: Deep Space Nine Technical Manual, on the other hand, describes an "ACB-jacketed beam device" as the mechanism which allows phasers to function at Warp speeds.
According to later series, phasers release a beam of fictional subatomic particles called "rapid nadion", which are then refracted ("rectified") through superconducting crystals.
The Star Trek: The Next Generation Technical Manual indicates that the superconducting crystals used in phasers are called fushigi no umi, which is Japanese for "sea of mystery", and the phrase is written ふしぎの海 in the original glyphs.
Disruptors are employed by several alien species in this series, including Romulans, Klingons, Breen, Cardassians, Iridians and Orions in their personal and military small arms as well as being mounted as cannon, emitters, turrets, and banks.
Phased polaron cannons are the primary armament of the Dominion, the main antagonist faction in the later seasons of Star Trek: Deep Space Nine.
In the TOS episode, "Balance of Terror", photon torpedoes had replaced nuclear warheads as the primary wartime weapons on Federation starships.
In Star Trek: Voyager, Tuvok and Kim modify a normal photon torpedo with a gravimetric charge, a piece of Borg technology, to increase its destructive yield to 54 isotons.
In Star Trek VI: The Undiscovered Country, Spock and Dr. McCoy modify a photon torpedo to track the plasma emissions from a cloaked Klingon bird of prey as it attacks the Enterprise-A and the Excelsior, similar to the principal function of a heat-seeking missile.
Although they do not appear in the film Nemesis, according to the non-canon Destiny book trilogy these are kept by Starfleet as the weapon of last resort to be deployed to starships only when all else had failed against the Borg.
The demonstration of the weapon destroys a target buoy composed of 10 m thick solid monotanium with a chromoelectric forcefield in one shot, coring it cleanly through.
It is introduced in the Star Trek: Deep Space Nine episode "Field of Fire", where it is used in conjunction with a micro-transporter and a visual scanner headpiece to create an extremely potent sniper rifle.
Using a nanite-controlled trigger for reactant release allows vessels to deliver a high-energy plasma warhead payload within a Mark IV torpedo casing.
[29] Though dangerous, their reliability is not absolute, as Seven of Nine and Tuvok (as well as Kes in the alternate timeline presented in "Before and After") find an undetonated chroniton torpedo lodged in Voyager's hull, which in turn allow the crew to adapt the shields to withstand further attacks.
[29] The Kessok are a highly intelligent race that ally themselves with the Cardassians, albeit through deceit, in the video game Star Trek: Bridge Commander.
[30] It later features prominently in the plot of "Homecoming", the Star Trek: New Frontier short story in the 2008 Mirror Universe anthology Shards and Shadows, in which the rebels manage to steal a Romulan thalaron bomb intended for use by the Alliance, to strike a balance of power against them.
A team of terrorists attempted to steal Trilithium resin from the warp core of the Enterprise-D when it was docked at Arkaria Station to receive a baryon sweep.
[33] Captain Benjamin Sisko would later use a Trilithium resin torpedo to render a Maquis planet uninhabitable to all human life for fifty years by detonating it in the atmosphere.
[36] The bat'leth is the Klingon double-sided scimitar/hook sword/lujiaodao hybrid–edge weapon, designed by martial arts enthusiast and Star Trek: The Next Generation effects producer Dan Curry.
[38] A smaller version of this "belly–spear" (the literal Klingon translation) is used in the children's game of qa'vak, which incorporates spinning hoops, and hones assorted skills needed for hunting.
Designed by Dan Curry, it consists of a short, thick, curved blade with a metal guard extending back parallel with the grip to protect the hand.
In the Countdown comic, Nero's weapon is revealed to be the "Debrune teral'n", an ancient Romulan artifact that symbolized the empire's power; it is traditionally held by the presiding Praetor.
Tricobalt devices are not a standard armament of Federation vessels and yields are calculated in Tera-Cochranes, indicating that its mechanism is somewhat similar to the general reaction in a warp field.
Janeway calls Seven of Nine's "multikinetic neutronic mine" a "weapon of mass destruction," following up on a statement from Tuvok that it would affect an entire starsystem, destroying innocent worlds.
It possesses shields, phasers, a complement of quantum torpedoes, a Thoron shock emitter, a plasma wave weapon, engines capable of reaching at least Warp 9, and a sophisticated computer AI.
It was dragged into the Delta Quadrant in much the same manner as Voyager, and when unable to resolve the unforeseen situation it locked on to a planet that was similar to the one it was programmed to target, but which was inhabited by innocents.
They are much smaller than Dreadnought, being only a few feet in length, and while nowhere near as powerful, they are nonetheless classified as weapons of mass destruction, capable of destroying everything in a 200-kilometer radius with a highly focused antimatter explosion.
Upon capture in the "past" (2258) by the Romulan Nero, it was used as a planet-destroying doomsday weapon in conjunction with a plasma drill which bored a hole almost to the core of a planet.
A small amount of red matter was then activated at the bottom of the drilling site, creating a black hole in the heart of the planet that would tear it apart from within.
