The antiproton was a particle, an antimatter element with the opposite charge of a proton. In the early 25th century, antiproton energy constituted a common directed energy weapons type by the Alpha Quadrant Alliance. (TOS episode: "The Doomsday Machine", STO - Klingon War mission: "The Doomsday Device")

Technical use[]

In the 2365, the spin reversal system of the Federation Galaxy-class starship USS Yamato generated antiprotons. This was marked on a schematic on the secondary hull. (TNG episode: "Contagion")

In 2368, the USS Enterprise-D was able to track the brancher known as the Crystalline Entity by its trail of antiprotons. (TNG episode: "Silicon Avatar")

In 2369, Starfleet identified that the trace of residual antiprotons from firing a Romulan disruptor could be used to date when such a weapon had been fired. (TNG episode: "Face of the Enemy")

In 2371, the Jem'Hadar were able to detect the cloaked USS Defiant by using antiproton beams. (DS9 episode: "The Search, Part I")

When Tom Paris suffered mutation from a transwarp test flight in 2372, the Doctor of USS Voyager used bursts of antiprotons to reverse the mutation on a DNA-level. (VOY episode: "Threshold")

In 2373, the deflector dish of Federation Sovereign-class ships was charged with antiprotons. (TNG movie & novelization: Star Trek: First Contact)

Residual antiprotons emanating from cloaked ships could be used to detect such vessels. In 2379, the prototype IRW Scimitar employed an advanced form of cloaking device that left no detectable antiproton trace. (TNG movie: Star Trek: Nemesis)

Antiproton weaponry[]

In 2267, the planet killer employed an antiproton beam, consisting of pure antiprotons only, to destroy planets. (TOS episode: "The Doomsday Machine")

In 2366, the illusory Delta Rana warship, created by the Douwd Kevin Uxbridge to mimic the Husnock warship that ravaged Delta Rana IV, used beams of antiprotons and positrons. Its firepower could be modulated from the equivalent to forty megawatts to 400 gigawatts. (TNG episode: "The Survivors")

By 2409, antiproton-based directed energy weapons were available for handheld and shipboard use. Antiprotons, when confined into a beam, normally appeared crimson with a black void border. Up close, the energy looked a lot more unstable, similar to plasma and tetryon energy. However, Undine antiproton weapons were pale yellow in color. (STO - Klingon War missions: "Welcome to Earth Spacedock", "Diplomatic Orders")

Borg Unimatrix 0047 command ships fired antiproton weapons. (STO mission: "Borg Red Alert")

The bio-neural warheads equipped on Klingon battlecruisers dealt antiproton damage. (STO - Klingon Sector mission: "First City")

The Solanae-made Obelisk 1 starship fired antiproton weapons. (STO - Legacy of Romulus mission: "Sphere of Influence")

When the Annorax-class science dreadnought was launched during the Iconian War of 2410, vessels of the class were pre-equipped with a chroniton lance that fired antiproton beams. (STO - The Iconian War mission: "Time and Tide")

Other factions using antiproton-based directed energy weapons as a default during the 2400s and 2410s decades included: the Crystalline Entity, Fek'Ihri Horde, Iconian Empire, Malon Cooperative, Sphere Builders, Undine, and Voth. (STO video games: Legacy of Romulus, Delta Rising, Agents of Yesterday)

In the 29th and 31st centuries, ships of the resurgent Terran Empire, like the Paradox-class temporal dreadnought, fired antiproton weapons. (STO - Agents of Yesterday mission: "Assault on Terok Nor")
