Planet killer
The Star Trek Expanded Universe Database is for fanon and related content. See Memory-Alpha.org for the canon Star Trek wiki.
The planet killer, sometimes called the "doomsday machine", was an automated, self-propelled weapon capable of destroying entire class-M planets. It was encountered in 2267 by the Federation starships USS Enterprise and USS Constellation. Its origins are unknown, but based on its apparent trajectory, it was believed to have come from outside the Milky Way Galaxy.
The device was rendered inert when the Constellation exploded inside its forward opening. The Enterprise placed a warning buoy near the device and proceeded to the nearest starbase for repairs. (TOS: "The Doomsday Machine")

In an alternate timeline, when the Constellation detonated it triggered a reaction in the weapon's chroniton emissions and sent it through time to 2255 where it encountered and destroyed the USS Enterprise commanded by Christopher Pike. It duplicated and plunged the Federation into a conflict known as the Doomsday War. Spock, on the planet Gateway, was protected from the changes in the timeline and sent the USS Farragut, commanded by James Kirk, back in time through the Guardian of Forever, and with the help of the USS Daedalus and the USS Enterprise was able to stop the planet killer and correct the timeline.

[edit] Star Trek: Pioneer (PNR)
- This timeline allows for the events of STNV's "In Harm's Way" to occur.
After the planet killer was rendered immobile in System L-374, in 2271 a team of scientists traveled there abaord the USS Hawking to study the device. However to their astonishment when they arrived it had completely dissapeared. Sensor readings indicated a recent massive subspace distortion in the vacinity and it was assumed these has caused the weapon's destruction. (Star Trek: Pioneer (PNR): "Messengers of Doomsday, Part 1")
In fact what had occurred was far more dangerous. A month prior to the Hawking's arrival, the Borg had tested their first transwarp network. One aperture led to system L-374 and had pulled the planet killer into the conduit. At the time the Borg were unaware of this and so collapsed the conduit as was originally planned. This caused the device to fall into subspace where it drifted around for over a hundred years. In 2375, when the USS Voyager attempted to create a stable quantum slipstream, this, unknown to the crew at the time, pulled the doomsday weapon back into normal space where it emerged in the Delta Quadrant. The Borg quickly discovered and assimilated it with the intent of using it for their greatest achievement ever, the assimilation of the entire galaxy. Ultimately however their plan was foiled by Elizabeth Rand and the USS Pioneer; however the weapon once again disappeared. (Star Trek: Pioneer (PNR): "Messengers of Doomsday, Part 2", VOY: "Timeless")
[edit] Tales of the Seventh Fleet
In 2295, the USS Justice encountered the reactivated device. After a brief engagement in which most of the senior staff was injured, the device was eventually destroyed by a solar flare in system L-374. ("Return to Doomsday")
[edit] Notes
In the original TOS episode it was referred to as "the planet killer". Only in casual conversation was it compared to the "doomsday" weapons of the late 20th century.
[edit] Apocrypha
It is hypothesized that the Tales of the Seventh Fleet timeline could work with the STNV timeline, the thought being that the planet killer wasn't destroyed by the USS Justice when it was hit by the solar flare, but forced into a slingshot time warp which caused the events of "In Harm's Way" (Star Trek: New Voyages) to occur.
