The "'''planet killer'''" was an automated, self-propelled [[Doomsday Machine]] capable of destroying entire [[planet]]s. It was encountered in 2267 by the [[Federation]] [[starship]]s USS Constellation (NCC-1017) and USS Enterprise NCC-1701. Its origins were unknown, but based on its apparent trajectory, it was believed to have come from outside the [[Milky Way Galaxy]].

== Discovery ==
Around stardate 4202.1, the ''Constellation'', under the command of [[Rank|Commodore]] Matt Decker, encountered massive destruction in [[System L-370]]; all seven planets had been utterly destroyed.  Proceeding to [[System L-374]] (stardate 4202.3), the ship found three intact planets, and a fourth in the process of breaking up.  Orbiting the fourth planet was the planet killer, firing a beam of pure [[antiproton]]s at the planet and consuming the planet's rubble as fuel.

As the ''Constellation'' approached, it was attacked by the planet killer.  The ship's deflector shields were quickly overwhelmed by the onslaught, and the machine proved completely invulnerable to counterattack, because its hull was composed of pure [[neutronium]].  The ''Constellation'' sustained heavy damage; the main bridge was destroyed, the [[phaser]] banks were exhausted, and the [[warp drive]] was destroyed, impulse drive severely damaged.  In addition, the machine projected a powerful dampening field, cutting off all communications with [[Starfleet Command]], and somehow deactivating the ''Constellation'''s [[antimatter]] fuel and leaving the ship nearly powerless.

Unable to continue the attack or escape, Decker ordered the crew to evacuate to the third planet in the system.  Decker himself remained aboard as the last man.  However, having finished consuming the fourth planet, the machine then turned towards the third planet.  Decker tried to beam his crew back up, but the machine attacked again, damaging the [[transporter]].  He could only watch helplessly as the machine consumed the planet below and killed his entire crew of 400 men and women.

A short time later, the ''Enterprise'', under the command of [[Rank|Captain]] [[James T. Kirk]], received a faint and garbled distress signal.  Unable to make out any words aside from ''Constellation'', she entered system L-374 and found her sister ship drifting and abandoned, with Commodore Decker the sole survivor aboard.  Assessing the situation using the ''Constellation'''s sensor records taken by [[Science Officer]] Masada, [[Spock]] projected the weapon's origin.  He also determined, based on its present course, that it would enter the most densely populated regions of the [[Alpha Quadrant]], including the nearby [[Rigel X|Rigel system]].

== The Battle ==
As the ''Enterprise'' held alongside the ''Constellation'', it was suddenly and swiftly attacked by the planet killer. Although the ''Enterprise'' was more maneuverable, the weapon was extremely fast and gaining on its target. In the first volley, the ''Enterprise'' took heavy damage, with shields almost exhausted and transporters and communications damaged. While Captain Kirk was trapped with the boarding party aboard the ''Constellation'', Spock ordered evasive action. Commodore Decker, taken aboard the ''Enterprise'' for medical treatment, exercised his authority to assume command under Starfleet [[Starfleet General Orders & Directives|General Order 104]] and countermanded Spock's orders to avoid the machine and seek a clear space to warn Starfleet. With a combination of seeking retribution for the loss of his ship and crew, and the presumption that the nearby Rigel colonies would be the next target of the machine, Decker ordered an immediate attack on the weapon. However, the ''Enterprise'' was overwhelmed as quickly as the ''Constellation'' had been, and soon trapped by a [[Tractor Beam]] which was pulling the ship towards the planet killer's maw.

Meanwhile, on the ''Constellation'', Chief Engineer Montgomery Scott managed to effect partial repairs to the impulse engines and a single phaser bank. Kirk launched a diversionary attack on the Planet Killer that allowed both ships to escape. The planet killer apparently had a relatively simple and straightforward defensive computer program that only allowed it to engage single targets within a specific range. The immediate danger past, Captain Kirk ordered Decker relieved of command of the ''Enterprise''.

As the two Starfleet ships withdrew, the planet killer returned to L-374 and resumed consuming the planetary debris, taking in additional fuel. When Decker gave indications he was going to continue to press the attack despite narrowly avoiding disaster in the previous engagement, he was relieved of command by Spock under direct orders from Kirk on the basis that to continue to press the futile attacks would be indication he was suicidal, and was ordered to report to sickbay for a psychological examination.

Suffering from a mental break-down brought on by extreme stress and the loss of his ship, crew and command, Commodore Decker escaped custody and stole a [[Type-1 Personnel Shuttlecraft]] from the ''Enterprise'', piloting it on a suicide course directly into the weapon's maw, where it was quickly destroyed. However, the ''Enterprise'' sensors detected a small drop in the power output of the planet killer – the shuttlecraft's explosion, however small, had in fact caused some minor damage to the weapon from the inside. Based on this data, Captain Kirk proposed detonating the ''Constellation'' 's main impulse engines inside the Planet Killer, creating a much bigger explosion and hopefully causing major damage to the weapon, if not destroying it outright.

As the ''Enterprise'' held position near the Planet Killer, outside of weapons range, Kirk piloted the ''Constellation'' on a direct course toward the weapon.  Beaming out at the last second, he detonated the ''Constellation's'' engines directly inside the weapon's maw, bypassing the neutronium hull, and effectively dropping its power output to zero (in essence completely disabling the machine). It should be noted that due to the presence of the seemingly impenetrable neutronium hull, the hulk (or "corpse") of the planet killer was left intact, floating lifelessly in space. Following the battle, Captain Kirk noted in his log that Commodore Decker gave his life in the line of duty.  (TOS|The Doomsday Machine)

-==A Blast from the Past==

-In 2407, the Doomsday machine was active again after the crew of an [[Orion Syndicate]] [[starship]] boarded the vessel and managed to reactivate it. The original plan was to control the device through the use of a specially designed control system that they had integrated into the devices control systems.
-The [[Orion]]s, however failed to realize that the device had an automated repair and defense system that was reactivated when the power was restored. The device resumed it's function of destroying planets, and also destroyed the Orion starship at the same time, but not before the vessel managed to send out a distress signal.
-Responding to the Distress signal, the [[USS Boudicca]] devouring the rest of [[System L-374]] in the [[Alpha Quadrant]]. Once complete, the massive weapon did not resume it's original course towards [[Rigel X]] but instead adopted the course introduced by the [[Orion]]s. It was a course that would direct the [[Doomsday Machine]] through the [[Klingon Empire]] to [[Qo'noS]].
-The original intentions of the [[Orion]]s was to use the device to blackmail the [[Klingon]]s into releasing several thousand [[Orion Syndicate]] prisoners captured during raids.
-Unable to attack the Planet Killer, The crew of the Boudicca dispatched an away team led by [[Matthew McLaren]] to board the device using a modified [[Danube Class Runabout]].
-The away team was successful in disabling the device and narrowly escaped the Planet Killer before it was shut down for a second time. During the action however members of the away team were either killed or seriously injured. [[Antiproton]] radiation used as weapons by the device's automated defense robots caused muscular degeneration in Matthew McLaren's body which resulted in his confinement to a gravity chair for the better part of a year.
-The hulk of the Planet killer was towed back into [[Federation]] Space where it was parked in a stable orbit at a scrapyard, although federation scientists were not permitted to board the vessel for fear of reactivating it.
