The Kobayashi Maru scenario was an infamous no-win scenario that was part of the curriculum for command-track cadets at Starfleet Academy in the 23rd century. It was primarily used to assess a cadet's discipline, character and command capabilities when facing an impossible situation, as there is no one answer to the problem.
In 2285, in the simulated bridge, the cadet was placed in command of the USS Enterprise on patrol near the Klingon Neutral Zone. The starship would receive a distress signal from the Kobayashi Maru, a civilian freighter that had been disabled in the zone after having struck a gravitic mine. If the cadet chose to enter the neutral zone in violation of treaties, the starship would be confronted by three Klingon Template:ShipClass battle cruisers. The test was considered a no-win scenario because it was impossible for the cadet to simultaneously save the Kobayashi Maru, avoid a fight with the Klingons and escape from the neutral zone with the starship intact. A cadet's choice of how to handle the rescue operation gave great insight into his or her command decision-making.
In the 2250s, James T. Kirk became the first (and only known) cadet to ever beat the no-win scenario. After taking the test and failing twice, Kirk took the test a third time after surreptitiously reprogramming the computer to make it possible to win the scenario.
Kirk was subsequently awarded a commendation for "original thinking" and later commented, wistfully, that his stunt "had the virtue of never having been tried." Kirk also went on to defend his "cheating" by arguing that he didn't believe in the no-win scenario. Ironically, Kirk additionally defended the test itself by suggesting, "How we face death is at least as important as how we face life."
In 2285, Kirk, then an admiral serving as an instructor at the Academy, supervised Lieutenant Saavik's performance in the Kobayashi Maru scenario. Former Enterprise crew members Spock, Sulu, Uhura and McCoy participated as "actors" in the simulation. Saavik's performance was predictably dismal; as Kirk observed to Spock, "She destroyed the simulator room and you with it." Spock had never taken the Kobayashi Maru test, but before he died of radiation poisoning, he described his sacrifice to save the Enterprise as his solution to the scenario. (Star Trek II: The Wrath of Khan)
While breaking Leonard McCoy out of a Federation prison and plotting to steal the Enterprise from the Spacedock in Earth orbit, Admiral Kirk contacted Commander Chekov with the coded message "The Kobayashi Maru has set sail for the promised land." (Star Trek III: The Search for Spock)
The term "Kobayashi Maru" may be a slang term for any hopeless situation in the 23rd century, at least in Starfleet culture. Leonard McCoy considered his and James T. Kirk's imprisonment on Rura Penthe to be a "Kobayashi Maru" and told Kirk as much, on their first night at the penal mine. (Star Trek VI: The Undiscovered Country)
A similar simulation was later used in the 24th century. It involved a damaged Ferengi ship as well as Romulan Template:ShipClass Warbirds, instead of a civilian freighter and Klingon battle cruisers, and was performed on the holodeck. (VOY: "Learning Curve")
In the alternate reality, the Kobayashi Maru test was programmed by Spock between 2254 and 2258. Its purpose was to cause the cadets to "experience fear in the face of certain death" and learn to remain in control of themselves and their ship, despite that fear. In the simulation, Starfleet Command specifically ordered the USS Trainer to rescue the USS Kobayashi Maru from a fleet of attacking Klingon warbirds.
In 2258, James T. Kirk, on his third attempt at the scenario, inserted a subroutine to make it winnable by eliminating the attacking Klingon vessels' shields and rendering them vulnerable to a single photon torpedo strike. A hearing was called in front of the entire assembly of Starfleet cadets to determine Kirk's guilt but the proceedings were interrupted by a distress call from Vulcan, which was under attack by the time-displaced Nero. Kirk was placed on academic suspension, until the Academy Council could rule on his case. (Star Trek)
The earliest version of the Kobayashi Maru scenario was in a script draft that Jack B. Sowards wrote for Star Trek II. In this document, the simulation was much as it is in the film's final version, involving the attempted rescue of the Kobayashi Maru and Kirk suggesting that the test might be a "no win scenario." (Star Trek: The Magazine Volume 3, Issue 5; )
In the audio commentary for the film Star Trek, writer and producer Roberto Orci states that he imagined that Spock also programmed the test in the prime reality, and that Kirk met him the same way after cheating.
The Kobayashi Maru scenario has also appeared in novels, short stories, video games and comic books.
- The origin of the Kobayashi Maru scenario was revealed in Michael A. Martin and Andy Mangels' Star Trek: Enterprise novel Kobayashi Maru set in 2155. In it, the Kobayashi Maru – here a freighter carrying secret Starfleet equipment to set up a listening post near the soon-to-be-established Neutral Zone – was hit by a gravitic mine in the Gamma Hydra Sector. When Enterprise came to save the Maru, the Romulans attempted to use a telecapture device on Enterprise – thus allowing them to take control of the ship by remote – and bring in three D-5 class Klingon battle cruisers to ensure the elimination or capture of Enterprise. Jonathan Archer was faced with the decision of losing his ship and the survivors or sacrificing the survivors and ensuring the survival of Enterprise, thus the no-win scenario, as Archer had been told to protect the freighter at all costs. Systems begin to fail on Enterprise indicating the ship was about to be taken over and Archer reluctantly chose to retreat.
- Julia Ecklar's The Kobayashi Maru tells how Kirk, Pavel Chekov, Montgomery Scott and Sulu each faced the problem. In the novel, Kirk won the scenario by reprogramming the simulation so that the Klingons believed he was a famous starship captain, though he was only a cadet at the time. Chekov self-destructed his ship, taking the Klingons with him; to his humiliation, his instructor pointed out that ejecting his crew in lifepods did not save them, due to the explosions of the four warp-drive vessels and the attending radiation. Scott tricked the simulation into overestimating the effectiveness of a theoretical attack against the Klingon ships' overlapping shielding. Faced with proof that such attacks, although quite valid in theory, would not work in reality and that Scott knew this, Academy staff reassigned Scott from command school to Engineering (his true love - he had used this "solution" precisely because of these consequences). Sulu, given the consequences of entry into the Zone versus the slim chance of recovering the crew of the freighter, elected not to conduct a rescue operation.
- The Starfleet Academy game provides the test as one of the missions in the game scenario. Imitating Kirk, the player character has the choice to reprogram the simulator and win the mission. One of the options is to make the AI-Klingons believe that the cadet protagonist is a famous captain and obey him at once.
- In Peter David's Pocket TNG novel A Rock and a Hard Place, Jean-Luc Picard has some misgivings about accepting a maverick officer as Will Riker's temporary replacement, but is astounded to be told that said officer beat the Kobayashi Maru without cheating. In the short story 'Til Death, part of the The Sky's the Limit anthology it's stated that when Will Riker took the Kobayashi Maru he ordered an EVA suit brought to the bridge so that he could fight the enemy ships by hand. This gambit did not appear to have been successful.
- In Peter David's New Frontier novel Stone and Anvil, cadet Mackenzie Calhoun "wins" the scenario by destroying the freighter, disabling the attacking ships in the process, escaping with his ship and crew but killing those whom he had been attempting to rescue (he later defended his actions by claiming the scenario was clearly a trap and the freighter crew were most likely already dead - and if they were alive, this quick death was preferable to the treatment they would receive as prisoners. And the whole thing is probably a trap, the Kobayashi Maru is probably an enemy ship). By this time, the scenario had been upgraded with holodeck technology, enabling variations on the basic theme of a starship in trouble.
- In the novel Sarek by A.C. Crispin, Peter Kirk beats the scenario by using a knowledge of Romulan customs unanticipated by the test's designers, challenging their captain to ritual combat - since all other hostilities must cease during the duel, the Romulan ships can only watch as Kirk's ship rescues the Kobiyashi Maru crew and escapes unharmed.
- Comic book stories of the Star Trek (DC volume 2) series are based on Ecklar's scenario. Three short stories in the Strange New Worlds anthology series have also tackled it. In "The Bottom Line" by Andrew Morby (SNW III) and Shawn Michael Scott's "Best Tools Available" (SNW VI), Cadet Nog solves it in two entirely different (and thoroughly Ferengi) ways. Kevin Lauderdale's "A Test of Character" (SNW VII) depicts a different solution from Ecklar's, one in which Kirk's tampering is "cheating without cheating," since Kirk merely creates a level playing-field, where success is not guaranteed.
- Star Trek Online features a Kobayashi Maru-inspired mission wherein the objective is to defend a civilian transport from an increasingly difficult onslaught of enemy ships. The accolades (achievements in STO) for completing high-level waves directly reference James Kirk. The mission, appropriately enough, is called "No Win Scenario".
