Antarian Trans - stellar Rally The Antarian Trans - stellar Rally was a race held in the Delta Quadrant to commemorate a treaty signed by four factions who claimed the same area of territory . It was first held in 2377 . Hosted by the Antarian s , the race included vessels from the four factions , including the Aksani and the Chessu . Other species were free to enter the race upon permission . An example of this was the representing the United Federation of Planets . The 2377 race was coordinated by an Antarian ambassador named O ' Zaal . Requirements for the race included having a pilot and co - pilot . Additionally , vessels were limited to sub - light speeds and were required to use enriched deuterium fuel . The race course was over 2 . 3 billion kilometer s long , divided into three segments based on spatial objects . The course also featured obstacles such as K - class anomalies and dwarf star clusters . The major obstacle on the course made up most of the third segment : a wormhole named the Möbius Inversion , which is a level 6 subspace anomaly . The Antarian Trans - stellar Rally of 2377 . The Antarian Trans - stellar Rally of 2377 featured twelve vessels from species such as the Aksani , Chessu , Imhotep , , and Human . After a period of intense debate and negotiation , the Federation starship " Voyager " was selected as the host for the pre - and post - race ceremonies ( Selected as the still - tentative nature of the new peace meant that various decisions could be seen as concessions to the formerly divided sides , but " Voyager " could serve as suitably neutral ground due to their lack of ties to anyone else ) . Ambassador O ' Zaal gave the commencement speech from " Voyager " s bridge . " Voyager " launched a photon torpedo that marked the start of the race . The first segment . At 58 million kilometers left in the first segment , the Aksani , Imhotep , and Terrellian ships were battling for the lead . The number 3 ship was cut off by the number 8 ship ( species unknown ) in the Darla system . The number 3 ship then used the gravity of a gas giant to gain ground . The third segment . At the third segment , the " Delta Flyer II " was in third place behind the ships of Assan and Irina . Entering the Möbius Inversion , status from outside the wormhole was unknown . While in the Inversion , the " Delta Flyer " reversed their deflector polarity to deflect the shields of Assan and Irina ' s vessels , causing them to create a gap for the " Flyer " to take the lead . Upon exiting the Inversion , the race was halted after Joxom ( Irina ' s co - pilot ) was injured due to an explosion . Apparent sabotage . After an examination of the shield generator of the damaged ship , a phase inverter was discovered , which was purposely placed to cause the overload . Rally officials met in " Voyager " s briefing room with the three leading teams to discuss continuing the race , and all agreed that the race should continue after a short break to allow Irina to repair the damage to her ship . Harry Kim of " Voyager " was allowed to replace Irina ' s co - pilot Joxum . The race resumes . With the race resumed , the " Delta Flyer " was still in the lead . Irina ' s ship encountered an EPS system malfunction , but while Harry Kim suggested a solution , she rejected it . Irina left her seat and Kim ' s console started to overload ; when he moved away from the explosion , he found Irina aiming a weapon him . Kim quickly activated a control to tilt the ship and removed the gun from her grip . When Harry attempted to contact Antarian Security , he found that Irina had disabled the comm system , so Kim decided that they would wait until someone found them . The " Delta Flyer " still maintained the lead . However , an argument over personal issues between Tom Paris and B ' Elanna Torres lead him to stop the " Flyer " to discuss the issue . Assan ' s ship took the lead , flying past the halted " Delta Flyer " . While on Irina ' s ship , Kim figured out that the fuel converter she gave the " Delta Flyer " ( to use enriched deuterium ) was rigged to explode . Using a modulating pulse modified to mimic Morse code ( which Kim and Paris used in Paris ' Captain Proton holonovels ) , Kim was able to alert Paris and Torres that the converter was rigged . The converter had started to leak veridium isotopes , which were able to cause a warp core breach . The " Flyer " left the course towards a nearby Class J nebula to dump the core to prevent the explosion from destroying nearby vessels . The core was dumped , but the " Flyer " was damaged . At the same time , Assan ' s ship crossed the finish line first , winning the race . ( )
